Livestock Microchipping Laws in Georgia: What Counts as Official ID and When It Applies

If you raise cattle, horses, goats, or other livestock in Georgia, the question of what qualifies as official identification matters every time an animal crosses a state line, changes hands at auction, or needs to be traced during a disease investigation. Microchips and RFID ear tags are both radio-frequency identification technologies, but they are not interchangeable under Georgia or federal law — and using the wrong one at the wrong time can leave you out of compliance.

Georgia follows the federal Animal Disease Traceability (ADT) framework administered by USDA’s Animal and Plant Health Inspection Service (APHIS), which means the rules that govern official ID in the Peach State are largely shaped in Washington before they reach your farm. Understanding both layers — federal minimums and Georgia-specific requirements — is the only way to stay on the right side of the law.

This guide walks through how microchips and RFID ear tags are treated under Georgia and federal rules, which species can use each form of ID, and what you need to do to keep your records in order.

Pro Tip: Before moving any livestock out of Georgia, confirm identification requirements with the Georgia Department of Agriculture (GDA) Animal Disease Traceability coordinator, since receiving states may impose stricter rules than the federal minimums Georgia adopts.

Microchipping vs. RFID Ear Tags: What Counts as Official ID in Georgia

The terms “microchip” and “RFID ear tag” are often used interchangeably in casual conversation, but they describe two physically distinct devices with different regulatory roles. A microchip is a cylindrical radio frequency identification device (RFID) that is implanted in the subcutaneous tissue of an animal using a hypodermic needle for the purpose of identification. An RFID ear tag, by contrast, is an externally attached device clipped to the animal’s ear.

Externally attached microchips such as RFID ear tags are commonly used to identify farm and ranch animals, with the exception of horses. For most cattle, swine, sheep, and goats, the ear tag — not the implanted chip — is the standard official identification device under federal and Georgia rules. The implanted microchip fills a different role: it is the preferred or accepted form of official ID for equine and certain non-traditional livestock species where ear tagging is impractical or not recognized.

The current Animal Disease Traceability program began in 2013 through USDA-APHIS and establishes minimum identification and documentation requirements to trace livestock moving across state lines. Livestock species covered include cattle, bison, equine, goats, sheep, poultry, swine, and farmed deer. Traceability is achieved by applying a form of official ID to an animal. Georgia adopted the ADT standard set by the USDA, though other states may have more stringent rules.

In practice, this means a subcutaneous microchip implant does not substitute for an RFID ear tag when an ear tag is required — and an ear tag does not substitute for an implanted chip when a chip is required. Knowing which device your species needs is the starting point for every movement decision you make.

The Federal RFID Mandate and What It Means for Georgia Producers

The updated Animal Disease Traceability regulations, effective November 5, 2024, aim to enhance the nation’s ability to respond to and mitigate the impact of foreign or significant diseases affecting livestock. The most significant change for Georgia cattle and bison producers is the shift away from visual-only metal tags toward dual-readable electronic ear tags.

USDA-APHIS amended the animal disease traceability regulations to require that eartags applied on or after a date 180 days after publication of the final rule in the Federal Register 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. That effective date is November 5, 2024.

The types of cattle required to be identified when moving interstate remain unchanged. The list includes dairy cattle, sexually intact beef cattle 18 months or older, and rodeo and exhibition cattle. Cattle and bison of any age used for rodeo or recreational events, and cattle and bison of any age used for shows or exhibitions, also require electronic tags. Cattle and bison going directly to slaughter are exempted from official identification requirements.

Official metal tags that conform to the National Uniform Eartagging System and were applied before the November 5, 2024, deadline will continue to be accepted. If you tagged your animals before that date, you do not need to re-tag them. However, any new tag applied to a covered animal after November 5, 2024, must be an RFID-capable 840 tag that is both visually and electronically readable.

Important Note: The federal RFID mandate applies specifically to cattle and bison moving interstate. Swine, equine, sheep, goats, and other species each have their own identification requirements and are not subject to the cattle-specific November 2024 RFID ear tag rule. Check species-specific requirements separately before any interstate movement.

To support implementation of these regulations, the USDA continues to prioritize funding to offer no-cost electronic IDs for cattle moving interstate, aiming to reduce the financial burden on producers and encourage compliance. Contact the GDA Animal Disease Traceability coordinator to learn how Georgia allocates its share of federally funded RFID tags.

Which Livestock Can Use a Microchip as Official Identification in Georgia

The answer to this question depends almost entirely on species. For cattle and bison, an implanted microchip is not a recognized substitute for an official RFID ear tag under the federal ADT rule. But for equine and several non-traditional livestock categories, the subcutaneous chip is either the preferred form of ID or one of a small number of accepted options.

Horses and other equines moving interstate can be officially identified using a digital photograph or written description of the animal — or, in practice, an ISO-compliant implanted microchip. 840 AINs (Animal Identification Numbers) are available in microchip implants for equine and other species, making the implanted chip a recognized official identification device for horses under the federal framework.

For non-traditional livestock entering Georgia for exhibition purposes, the rules are explicit. All llamas, alpacas, and camels entering Georgia must be identified by a USDA-approved metal ear tag, unique and individual tattoo, notarized photograph, or an electronic identification device (microchip). If electronic identification is used, the consignee is responsible for providing the appropriate reading device for verification.

For sheep and goats, the National Scrapie Eradication Program governs official ID requirements. All sheep over 18 months of age, sexually intact sheep under 18 months sold for breeding or exhibition, and sheep sold unrestricted must carry official ID. Sexually intact goats not in slaughter channels of any age that do not meet requirements to be considered low-risk commercial goats must also be officially identified. Scrapie program tags — not implanted microchips — are the standard device for sheep and goats under this program.

If you raise goats in Georgia, the goat ownership laws in Georgia article covers the broader regulatory picture, including zoning and health certificate requirements that interact with identification rules.

When a Microchip Qualifies for Interstate Movement in Georgia

A microchip qualifies as official identification for interstate movement in Georgia when two conditions are met: the species must be one for which a microchip is a recognized official ID device, and the chip must meet the applicable ISO or USDA AIN standards.

For equine, an ISO-compliant implanted microchip is widely accepted as official identification for interstate movement. ISO-compliant electronic identification — such as a microchip — is an accepted form of official ID for equine. Non-ISO electronic identification injected into the equine on or before March 11, 2015, may also be recognized under certain conditions. An official RFID ear tag bearing an 840 AIN number is also an option for horses, but the implanted chip is the more common choice in the equine industry.

Unless specifically exempted, livestock traveling over a state border must be officially identified and accompanied by an interstate certificate of veterinary inspection (ICVI) or other documentation. The microchip number — or the ear tag number for species where ear tags are required — must be recorded on the ICVI. The official ID is recorded on a Certificate of Veterinary Inspection (CVI) or other movement document.

For cattle and bison, a subcutaneous microchip does not satisfy the interstate movement ID requirement. The federal ADT rule requires an official RFID ear tag for covered cattle and bison. No person may move covered livestock interstate or receive livestock moved interstate unless all requirements of 9 CFR Part 86 are met.

If you are moving livestock into Georgia from another state, note that it is unlawful for any person to ship or import any equines, poultry, livestock, or birds into Georgia unless accompanied by an official interstate or international certificate of veterinary inspection. The identification device on the animal must match what is recorded on that certificate.

Producers in neighboring states should also review the requirements in their home states. The rules for transporting livestock in Florida and transporting livestock in Kentucky each have their own documentation requirements that must align with Georgia’s entry rules when animals cross those borders.

Approved Microchip Standards and Placement by Species in Georgia

Not every microchip qualifies as official identification. USDA-APHIS specifies both the technical standard the chip must meet and the Animal Identification Number (AIN) format it must carry. Using a non-compliant chip — even one that scans correctly — will not satisfy official ID requirements for interstate movement or federal disease traceability purposes.

Approved devices for electronic identification include 134.2 kHz LF RFID tags compliant with both the ISO 11784 and ISO 11785 standards, or UHF RFID tags. Relevant standards for the chips are ISO 11784 and ISO 11785. These standards govern the frequency and data encoding format of the chip, ensuring any compliant reader can retrieve the identification number regardless of manufacturer.

For equine specifically, USDA-approved injectable transponders are available from multiple manufacturers. The Equine Slim injectable transponder (model T-SL 8010) is an FDX microchip carrying AIN number 0086, approved for equine and deer/elk. Placement in horses is typically in the nuchal ligament on the left side of the neck, which is the industry-standard location recommended by the American Association of Equine Practitioners and recognized by most state veterinarians.

For sheep and goats, USDA has also approved injectable transponders. The Sheep/Goat Slim injectable transponder (model T-SR 8010) is an FDX microchip carrying SCR number 0103, approved for sheep and goats. However, as noted above, scrapie program ear tags remain the primary official ID device for these species in most movement scenarios.

The table below summarizes the approved ID forms by species under Georgia’s adopted ADT framework:

Species	Primary Official ID Device	Microchip Accepted as Official ID?	Key Standard
Cattle & Bison	840 RFID ear tag (visually + electronically readable)	No — ear tag required	ISO 11784/11785; 840 AIN
Equine (horses, mules, donkeys)	ISO-compliant implanted microchip or description/photo	Yes	ISO 11784/11785; 840 AIN
Sheep & Goats	Scrapie program ear tag (visual or RFID)	Limited — injectable transponder approved but ear tag is primary	USDA Scrapie Program
Swine	Premises ID (PIN) ear tag for slaughter; tattoo for breeding	No standard microchip option for official ID	9 CFR Part 86
Llamas, Alpacas, Camels	USDA metal ear tag, tattoo, notarized photo, or microchip	Yes — with reader provided by consignee	ISO-compliant chip
Farmed Deer/Elk	840 AIN ear tag or injectable transponder	Yes — USDA-approved injectable transponder	ISO 11784/11785; 840 AIN

Pro Tip: Always verify that the chip or tag number on the animal matches the AIN recorded on the Certificate of Veterinary Inspection before any interstate movement. A mismatch — even a single digit — can result in the shipment being rejected at the state line.

Registering a Livestock Microchip in Georgia

Implanting a chip is only the first step. The chip number must be registered and linked to premises and ownership information before it has any practical value as official identification. An unregistered chip number on a CVI creates a documentation gap that can delay movement, complicate disease investigations, and undermine your ownership claim if an animal is lost or stolen.

For livestock subject to the federal ADT program, the chip’s AIN is tied to a Premises Identification Number (PIN). The official ID is recorded on a Certificate of Veterinary Inspection or other movement document, which means your accredited veterinarian needs the PIN and chip number on file before issuing the health certificate. Contact the Georgia Department of Agriculture at agr.georgia.gov/livestock to obtain or confirm your premises identification number.

For equine microchips specifically, registration through a national equine database — such as those maintained by breed registries or the American Association of Equine Practitioners — is the standard practice. The chip number, along with a physical description of the horse, is recorded in the database and linked to the owner’s contact information. This record is what a state veterinarian or border inspector will look up when verifying the chip against the CVI.

Having the microchip placed is only the first step; the microchip must be registered in order to give you the best chances of recovering your animal. If that information is missing or incorrect, your chances of getting your animal back are dramatically reduced. The same principle applies to livestock: a chip with no registration record is functionally useless in an emergency traceback scenario.

Georgia also maintains a brand registration system for cattle and horses. The Livestock & Poultry section of the Georgia Department of Agriculture regulates and monitors the sale and exhibition of livestock in Georgia. Livestock brands are reviewed and purged on a 5-year cycle, and everyone with registered brands must renew every year ending in 4 and 9. A microchip does not replace a registered brand, but the two forms of ID can be used together to strengthen your ownership documentation.

If you also keep backyard poultry or other small animals on your property, it is worth reviewing the backyard chicken laws in Georgia and beekeeping laws in Georgia to understand how GDA oversight applies across different animal categories on the same premises.

Microchipping as Proof of Ownership in Georgia

A microchip is not a title document, and Georgia law does not treat a chip scan as conclusive proof of ownership in the way a bill of sale or brand certificate would be. What a microchip does provide is a persistent, tamper-resistant link between an animal and a registered owner record — which makes it a powerful supporting piece of evidence in an ownership dispute.

Due to the fact that traditional identifications are on the exterior of the animal, tags can be lost, scars can heal, and tattoos can fade. A subcutaneous microchip, by contrast, cannot be accidentally removed and does not degrade over time under normal conditions. This permanence is precisely why it carries more weight than a visual tag in a dispute where an animal’s tags have been removed or replaced.

In Georgia, livestock ownership disputes are governed by the state’s general property laws and the specific provisions of O.C.G.A. Title 4. A registered chip number that matches the animal’s CVI history, purchase records, and premises registration creates a chain of documentation that is difficult to challenge. Conversely, an animal with a chip registered to someone else’s premises raises an immediate question of provenance that you would need to address with additional documentation.

For horses, the combination of an ISO-compliant microchip, a breed registry record, and a current Coggins test creates the strongest possible ownership package. State veterinarians and law enforcement in Georgia are familiar with scanning horses for chips when ownership is in question, and the Georgia Department of Agriculture’s Equine Program oversees stable licensing and equine welfare complaints statewide.

If a livestock animal strays onto your property or you find one on a public road, the chip can help identify the owner quickly. Georgia’s livestock-at-large laws under O.C.G.A. Title 4 govern what happens when animals stray, and the microchip record — combined with the GDA’s premises database — is one of the fastest ways to locate a registered owner. Related animal law topics that Georgia producers and landowners often encounter include neighbors’ dog on your property laws in Georgia and dog bite laws in Georgia, both of which involve similar questions about ownership documentation and liability.

Microchipping also intersects with Georgia’s pet import rules for animals that cross the line between livestock and companion animal categories — such as miniature horses or pot-bellied pigs. The pet import laws in Georgia article covers the health certificate and identification requirements for animals entering the state that may not fall cleanly under the livestock ADT framework.

Key Takeaway: A microchip strengthens your ownership claim but does not replace a bill of sale, brand registration, or CVI. Keep all four documents current and cross-referenced to each other for the strongest possible ownership record under Georgia law.

Georgia livestock producers who stay on top of identification requirements — knowing which device each species needs, which standard the chip must meet, and how to register the number — are better positioned to move animals smoothly across state lines, respond quickly to disease investigations, and protect their property rights if an animal is lost, stolen, or disputed. The rules are layered, but they are manageable once you understand which layer applies to your operation.
