Livestock Ear Tag Requirements in Florida: What Every Producer Needs to Know

Florida is one of the top cattle-producing states in the nation, and that means livestock identification rules matter — not just at the state level, but under federal law as well. Whether you run a cow-calf operation in Okeechobee, raise sheep in the Panhandle, or move hogs across state lines, knowing which animals need official ear tags, what type of tag qualifies, and how to document everything correctly can protect you from fines, rejected shipments, and disease-outbreak liability.

This guide covers every layer of Florida’s livestock ear tag requirements — from the federal RFID rule that took effect in November 2024 to Florida-specific species rules, where to obtain compliant tags, how to apply them correctly, and what records you need to keep. If you move animals across state lines or sell through a Florida livestock market, this is the information that keeps your operation compliant.

Which Animals Require Official Ear Tags in Florida

Not every animal on your property needs a government-issued ear tag. Florida’s identification requirements, administered by the Florida Department of Agriculture and Consumer Services (FDACS) Division of Animal Industry, mirror the federal minimums set by USDA APHIS under 9 CFR Part 86. The trigger for official identification is almost always movement — not simply owning the animal.

The basic concept is that all adult cattle and bison 18 months old or older being transported or sold must have an approved official USDA identification device or tag, unless they are going directly to a slaughter facility. Florida aligns with this baseline, and it extends similar logic to other species covered under the federal Animal Disease Traceability (ADT) framework.

The species and categories that trigger official ID requirements in Florida include:

• Cattle and bison — sexually intact animals 18 months of age or older, all dairy cattle of any age, and any cattle or bison used for rodeo, recreation, shows, or exhibitions
• Sheep and goats — all animals moving interstate or through concentration points such as livestock markets
• Swine — domestic swine moving interstate or sold through markets
• Captive cervids — deer and elk moving interstate under 9 CFR Part 77
• Equines — horses and other equids moving interstate, with limited exceptions

Florida’s rules do not require that cattle be tagged while they remain on the ranch of origin. USDA tags are only required before animals are transported to a new owner. That said, if your animals will ever leave your property for sale, a show, or interstate transport, you need to have a compliance plan in place before that day arrives.

Pro Tip: Register your premises with FDACS before you need tags. You cannot order official USDA 840 RFID tags without a valid Premises Identification Number (PIN), and getting one takes time. Contact the FDACS Division of Animal Industry at (850) 410-0900 to start the process.

Federal RFID Ear Tag Rule: What Changed in November 2024

The single biggest shift in livestock identification in a generation took effect on November 5, 2024. New federal rules require electronic identification (EID) ear tags for certain cattle and bison moving across state lines. The rule, published by USDA APHIS, replaces the old system of visual-only metal tags with radio frequency identification (RFID) tags that can be read electronically.

USDA APHIS amended the animal disease traceability regulations to require that eartags applied on or after the effective date be both visually and electronically readable in order to be recognized for use as official eartags for interstate movement of cattle and bison covered under the regulations. The rule was published in the Federal Register on May 9, 2024, and USDA published the final rule on May 9, 2024, making the effective date November 5, 2024.

The rule specifies that ear tags for all sexually intact cattle and bison 18 months of age or older, all dairy cattle, cattle and bison of any age used for rodeo or recreation events, and cattle or bison of any age used for shows or exhibition must be both visually and electronically readable in order to be recognized for use as official identification for interstate movement.

A key protection for existing operations: cattle tagged with visual-only official tags prior to November 5, 2024, do not need to be retagged unless they lose their ID. However, currently, the only official tags that meet the new requirements are 840 RFID tags. This requirement applies to official identification placed for any reason, including interstate movement, brucellosis vaccination, and tuberculosis testing.

These changes only apply to official ID for cattle and bison. The purpose of this rule is to improve livestock traceability. Electronic identification tags and systems provide many advantages over traditional metal tags, including faster information sharing, more accurate and precise identification of animals, and significantly faster record searches during disease outbreaks.

Important Note: Florida was already ahead of many states on RFID adoption. According to the National Cattlemen’s Beef Association, Florida was among a small group of states — including Michigan, Colorado, and Kentucky — that had their own RFID requirements in place before the federal rule was finalized. The November 2024 federal rule now sets a uniform national floor.

Official 840 RFID Ear Tag Requirements in Florida

An “official” ear tag in Florida means a tag that meets USDA APHIS standards — not just any commercially available ear tag. Official EID are USDA-approved official tags that have a visible 15-digit number starting with 840 printed on them that matches the electronic chip inside the tag, are stamped with the US shield, and say “unlawful to remove.”

The number “840” is the country code for the United States. After the 840, these tags have 12 other numbers unique to that animal. The term “RFID” refers to radio-frequency identification, meaning those tags can be read with a special scanner.

The physical requirements for an official 840 tag include:

• A 15-digit Animal Identification Number (AIN) beginning with 840, printed visually on the tag and encoded electronically in the RFID chip
• The official U.S. Route Shield graphic with “US” or the state postal abbreviation imprinted within it
• The phrase “Unlawful to Remove” printed on the tag
• Approval from USDA APHIS — tag companies must submit specific products to APHIS for approval, and the agency maintains a list of approved tag providers

Since March 11, 2015, all official eartags applied to animals must bear an official eartag shield. Tags that predate this requirement may still be grandfathered, but any new tag you apply today must carry the shield.

Two RFID formats are currently in use: Full-Duplex (FDX) and Half-Duplex (HDX). Both HDX and FDX tags adhere to ISO standards and are compatible with the same EID readers. HDX tags excel at transmitting signals through interference, such as metal objects and fluorescent lights. Either format is acceptable as official ID when the tag is otherwise USDA-approved.

To order official 840 tags, you must have a valid Premises Identification Number. A Premises ID is required to purchase USDA tags. Your PIN is a seven-character alphanumeric identifier permanently assigned to your physical operation address through the FDACS Division of Animal Industry.

Species-Specific Ear Tag Rules in Florida

The 840 RFID rule is primarily a cattle and bison rule. Other species follow separate federal and state identification frameworks, and Florida producers need to understand the distinctions before moving any animal off their property.

Cattle and Bison

As described above, the 2024 rule applies to sexually intact cattle at or over the age of 18 months; all female dairy cattle of any age; male dairy cattle born after March 11, 2013; and all cattle used for rodeo, showing, or exhibitions. Beef feeder cattle under 18 months are generally exempt unless the destination state or a federal disease program requires identification. Beef cattle less than eighteen months of age are exempt from the official identification requirement for interstate movement under Florida’s importation rules.

Sheep and Goats

All sheep and goats must have official USDA identification tied to their flock or herd of birth. Acceptable forms include USDA tags, tattoos combined with a registration certificate, or microchips. The federal scrapie eradication program drives most of the sheep and goat ID requirements in Florida.

Sheep and goats that are required to be officially identified for interstate movement must be identified by a device or method authorized under the applicable federal scrapie regulations. Do not use cattle RFID tags on small ruminants — these animals have their own RFID tags. The 840 RFID format is available for sheep and goats, but the tag must be species-specific and USDA-approved for those animals.

All sheep and goats imported into Florida, except those consigned to slaughter, must be accompanied by a health certificate dated not more than 30 days before import. The health certificate must include the official individual identification of each animal and a statement that each animal is free of the clinical signs of caseous lymphadenitis, contagious ecthyma, chlamydial keratoconjunctivitis, scabies, scrapie, and contagious foot rot.

Swine

Domestic swine must also have official USDA identification and an Official Certificate of Veterinary Inspection (OCVI, or health papers) not more than 30 days old, just like other livestock species. Swine that are required to be officially identified for interstate movement must be identified by a device or method authorized under the applicable federal swine identification regulations. Florida requires that swine moving through markets or crossing state lines carry valid official ID before departure.

Equines

Horses and other equids moving interstate must be officially identified prior to the interstate movement, unless they are used as the mode of transportation — such as horseback or horse and buggy — for travel to another location and then return directly to the original location. Official ID for equines may include an 840 microchip implant, a lip tattoo, or other USDA-approved method. Florida requires an OCVI for most equine imports.

Captive Cervids

Captive cervids that are required to be officially identified for interstate movement must be identified by a device or method authorized under 9 CFR Part 77. Florida has specific cervid regulations under the Florida Fish and Wildlife Conservation Commission in addition to FDACS requirements, so check both agencies before moving deer or elk across state lines.

Pro Tip: Use InterstateLivestock.com to look up the exact identification and health certificate requirements for any species moving from Florida to a specific destination state. Veterinarians responsible for health certificates, or livestock owners planning interstate travel with livestock, can see every requirement based on the state an animal is coming from and the specific state where it is going by using the InterstateLivestock.com website.

Where to Get Official Ear Tags in Florida

Florida producers have several options for obtaining official 840 RFID tags, ranging from no-cost government distribution to direct purchase from authorized manufacturers.

No-Cost Tags Through FDACS

EID tags are issued through the state veterinarian’s office at no cost to producers. There is also a limited supply at the district FDACS offices. However, supply is finite. States are provided an annual allotment of tags to distribute within the state specifically for use in replacement heifers. In Florida, these tags are distributed to accredited veterinarians for use with official activities — calfhood brucellosis vaccination, tuberculosis testing, Certificates of Veterinary Inspection, and similar — and to district FDACS offices. The annual allotment is less than 10% of the annual calf crop in the state, which means FDACS must limit the number of tags provided to any single producer.

Contact the FDACS Division of Animal Industry directly at (850) 410-0900 or email [email protected] to inquire about tag availability in your district. Your local accredited veterinarian may also carry a supply of no-cost tags for use during official health activities.

Purchasing Tags from Approved Manufacturers

When the free allotment runs out — or if you need tags in volume — you can purchase directly from USDA-approved manufacturers. Three major manufacturers produce approved 840 tags: Allflex (Dallas, TX), Datamars (Temple, TX), and Y-Tex (Cody, WY). Tags are available through veterinary supply distributors, farm supply stores, and directly from manufacturers.

RFID 840 tags cost between $2 and $5 per tag, depending on the manufacturer, tag style, and order quantity. You will need to provide your Premises Identification Number when ordering. USDA tags cannot be shipped to a different state from the state that the Premises ID is registered to, so make sure your PIN is current and tied to your Florida address before placing an order.

Source	Cost	PIN Required	Best For
FDACS District Offices	No cost (limited supply)	Yes	Small producers, replacement heifers
Accredited Veterinarian	No cost during official activities	Yes	Brucellosis vaccination, TB testing
Allflex, Datamars, Y-Tex (direct)	$2–$5 per tag (as of 2024)	Yes	Commercial operations, volume orders
Farm supply / vet supply distributors	$2–$5 per tag (as of 2024)	Yes	Convenience, mixed-species operations
Approved livestock markets (tagging sites)	Varies by market	Market handles registration	Producers without squeeze chutes

Florida’s rules allow cattle producers to have their cattle tagged at livestock markets that become approved tagging sites. Ranchers who do not have a squeeze chute or head catch will be able to have cattle tagged at local markets prior to sale. This is a practical option for smaller operations, though markets may charge a fee for the service.

How and When to Apply Ear Tags in Florida

Applying an official ear tag correctly matters as much as using the right tag. A tag that falls out or is placed improperly can leave an animal unidentified at a critical moment — and replacement tags must be applied before the animal moves again.

Placement Guidelines

USDA prefers producers apply ear tags in the left ear, leaving the right ear for official use. More specifically, all ear tags should be placed two-thirds of the way from the outside edge of the ear, and one-third of the way from the head between the middle two cartilage ribs. This placement avoids major blood vessels and cartilage ridges, which reduces the chance of tag loss and infection.

For cattle and bison, the official brucellosis vaccination tag — an orange RFID button — follows a specific protocol. The new official brucellosis identification is an orange RFID button, placed in the right ear by the herd veterinarian at the time of vaccination. Only an accredited veterinarian may apply brucellosis vaccination tags.

Timing Requirements

Tags must be in place before the animal leaves your property for any non-exempt purpose. USDA tags are only required before animals are transported to a new owner. However, if you are moving cattle to a show, a rodeo event, or across state lines for any reason other than direct slaughter, the tag must be applied before loading — not at the destination.

The exceptions to pre-movement tagging in Florida are narrow:

• Animals moving directly to a recognized slaughter establishment
• Animals moving through no more than one USDA-approved livestock facility and then directly to slaughter
• Animals moving to an approved tagging site (such as a licensed livestock market)
• Animals moving between premises under common ownership as part of normal farm operations, provided cattle are not commingled with animals under separate ownership

If a tag is lost after application, it will only need to be replaced when the new owner decides to sell the animal, and the replacement tag will be assigned to that owner’s ranch premise. Keep records of the original tag number and the replacement so your documentation chain stays intact.

Applicator Tools

Each tag manufacturer produces an applicator designed for their specific tag. Using the wrong applicator can damage the RFID transponder inside the tag or cause the tag to seat improperly. Y-Tex 840 USDA FDX EID tags require the Y-Tex Ultra Tagger Plus for EID and tamperproof tags. Check the manufacturer’s instructions for your specific tag brand before applying. For small ruminants, use species-specific applicators — the button size and pin diameter differ from cattle tags.

Ear Tag Requirements for Interstate Movement in Florida

Moving livestock out of Florida — or receiving animals from another state — triggers both federal traceability requirements and Florida’s own importation rules. Understanding both layers prevents delays at inspection stations and keeps your health certificates valid.

Florida operates agricultural inspection stations at key entry points. Chapter 570 of the Florida Statutes gives FDACS the authority to regulate the transportation of agricultural products, food, and livestock into the state of Florida. FDACS’s Office of Agricultural Law Enforcement (OALE) has the primary responsibility to enforce laws involving livestock, poultry, aquaculture, and other animals.

What You Need to Move Livestock Out of Florida

For cattle and bison, cattle and bison moved interstate must be accompanied by an Interstate Certificate of Veterinary Inspection (ICVI) unless they are moved directly to a recognized slaughtering establishment, or directly to an approved livestock facility and then directly to a recognized slaughtering establishment, and they are accompanied by an owner-shipper statement.

The ICVI — commonly called a health certificate or “papers” — must be issued by an accredited veterinarian and is typically valid for 30 days. It must list the official individual identification (tag number) of each animal. The USDA also made minor changes to the traceability rule, including clarifying the definition of dairy cattle and making small adjustments to the definition of the Interstate Certificate of Veterinary Inspection to accommodate electronic documentation.

For sheep and goats, sheep and goats moved interstate must be officially identified prior to the interstate movement unless they are exempt from official identification requirements or are officially identified after the interstate movement as provided under the applicable federal regulations.

For swine, swine moving interstate must be officially identified in accordance with the applicable federal swine identification regulations. Florida also requires an OCVI for swine imports, dated no more than 30 days before entry.

What Florida Requires for Incoming Livestock

Florida’s importation rules under Chapter 5C-3 of the Florida Administrative Code require that all incoming livestock carry valid official identification and a current health certificate. A Permit for Interstate Movement from a USDA Approved Livestock Facility, or an equivalent form approved by the state of origin, can be issued by an approved livestock facility as a valid interstate movement document for cattle moving between Florida, Alabama, Georgia, or Mississippi.

If you are transporting livestock into Florida from other states, be aware that FDACS inspection stations check documentation at the border. FDACS enforcement has historically focused on Peninsular Florida with inspection stations at key points positioned for incoming traffic from Georgia, but enforcement is expanding to inspect incoming traffic from Alabama in the Panhandle. A new inspection station is under construction on Highway 231 just north of Campbellton, Florida at the Florida-Alabama state line.

Recordkeeping Requirements for Ear-Tagged Animals in Florida

Ear tags are only as useful as the records that back them up. Federal regulations under 9 CFR Part 86 establish minimum recordkeeping requirements for anyone involved in distributing, applying, or moving officially identified livestock.

Tag Distribution Records

Any state, tribe, accredited veterinarian, or other person or entity who distributes official identification devices must maintain for 5 years a record of the names and addresses of anyone to whom the devices were distributed. Official identification device distribution records must be entered by the person distributing the devices into the applicable tribal, state, federal, or other acceptable database.

If you receive tags from your accredited veterinarian or a district FDACS office, the distributor is responsible for entering that transaction into the system. Your responsibility is to record which tag numbers were applied to which animals on your premises.

Records for Veterinarians

Records of official identification devices applied by a federally accredited veterinarian to a client animal must be kept in a readily accessible record system. Veterinarians who apply tags during official activities — brucellosis vaccination, TB testing, or CVI issuance — must be able to produce those records on request by state or federal animal health officials.

Records for Livestock Facilities

Approved livestock facilities must keep any ICVIs or alternate documentation required for the interstate movement of covered livestock that enter the facility on or after March 11, 2013. For poultry and swine, such documents must be kept for at least 2 years, and for cattle and bison, sheep and goats, cervids, and equine species, 5 years.

If you sell through a Florida livestock market, the market is responsible for maintaining those movement records. You should still retain your own copies of any health certificates and owner-shipper statements for your records.

What Producers Should Keep on File

While federal rules do not currently require individual producers to maintain tag application records in the same way that distributors and veterinarians do, good practice — and Florida’s ability to trace disease outbreaks — depends on producers keeping organized records. At a minimum, maintain:

• A log of tag numbers received, including the date received and the source (FDACS, veterinarian, or manufacturer)
• A record of which tag number was applied to which animal, including the animal’s description, breed, sex, and approximate age
• Copies of all ICVIs and health certificates associated with animal movements, retained for at least 5 years
• Owner-shipper statements for any cattle moved to slaughter or through approved livestock facilities
• Records of any lost or replaced tags, including the original tag number and the replacement tag number

Pro Tip: Electronic recordkeeping tools — including herd management apps and the USDA’s Animal Identification Management System — make it easier to link tag numbers to individual animal records. RFID allows a quicker response during disease investigations because animal health officials can process tag information electronically. The same efficiency benefit applies to your own herd management.

If state or federal animal health officials request your records during a disease investigation, additional recordkeeping requirements include the retrieval of official identification distribution records and certificates of veterinary inspection within 48 hours of a request made by federal or state animal health officials. Having organized, accessible records means you can respond quickly and demonstrate compliance without disruption to your operation.

For producers moving animals across multiple state lines, the requirements of each destination state may add layers beyond what Florida requires. Review the USDA APHIS Animal Disease Traceability page for the federal framework, and consult InterstateLivestock.com for state-by-state specifics. Florida producers shipping into neighboring states can also review dedicated guides for livestock trailer requirements in Georgia and livestock trailer requirements in Alabama to understand what those states expect when your animals arrive.

Livestock ear tag compliance in Florida is not complicated once you understand the framework — federal rules set the floor, FDACS enforces and often mirrors those rules, and species-specific programs handle the details for sheep, goats, swine, and cervids. Getting your premises registered, ordering the right tags before you need them, applying them correctly, and keeping clean records are the four steps that keep your operation on the right side of the law every time an animal leaves your property.
