Livestock Microchipping Laws in Utah: What Every Producer Needs to Know

If you raise cattle, horses, sheep, goats, swine, or captive cervids in Utah, the question of official animal identification is not academic — it directly affects whether your animals can legally cross a state line, change hands, or be presented at a show. Microchips and RFID ear tags are often discussed in the same breath, but Utah law and federal regulations treat them very differently depending on species, purpose, and the direction of movement.

This guide breaks down exactly where microchips fit into Utah’s official ID framework, how the federal RFID mandate reshapes your obligations, and what you need to do before moving an animal off your premises.

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

The first thing to understand is that “microchip” and “RFID ear tag” are not interchangeable in Utah’s regulatory framework. Utah’s animal disease control regulations under Rule R58 are designed to eliminate or reduce the spread of disease by setting standards for the movement of animals both within the state (intrastate) and into the state (interstate). Within that framework, “official identification” is a defined term — and not every electronic device qualifies.

For cattle and bison, the standard official ID is an RFID ear tag, not a subcutaneous microchip. A USDA rule effective November 5, 2024, requires newly applied cattle and bison official ID tags to have both a visual and electronic component, and as of that date the only official tags meeting these requirements are 840 RFID ear tags. A microchip implanted under the skin does not satisfy this requirement for cattle or bison.

For other species — particularly equines, sheep, goats, and captive cervids — an implanted microchip can qualify as official ID, but only under specific conditions. Sheep and goats that are required to be officially identified for interstate movement may use electronic implants when accompanied by a certificate or owner statement that includes the electronic implant numbers and the name of the chip manufacturer. Captive cervids have their own distinct rule covered later in this article.

Pro Tip: Before purchasing any microchip or RFID device, confirm with the Utah Department of Agriculture and Food (UDAF) Division of Animal Health that the specific product is on the USDA-approved list for your species. Using an unapproved device can invalidate your official ID entirely.

The Federal RFID Mandate and What It Means for Utah Producers

The biggest regulatory shift in recent years came from the federal level, and it has direct consequences for Utah ranchers and farmers. USDA’s Animal and Plant Health Inspection Service (APHIS) amended the animal disease traceability regulations to require that ear tags applied on or after November 5, 2024, be both visually and electronically readable in order to be recognized as official ear tags for the interstate movement of covered cattle and bison.

This means all dairy females and males born after March 11, 2013, exhibition and rodeo cattle, and sexually intact beef cattle 18 months of age and older must be officially identified before moving interstate. If you are a Utah beef producer moving older breeding stock to a sale barn in Nevada or Colorado, those animals need a compliant 840 RFID ear tag applied after the November 5, 2024 deadline — a visual-only metal tag no longer suffices for new applications.

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. So animals you tagged years ago are not automatically out of compliance — but any new tag you apply must be an electronic 840 RFID tag.

The ADT program applies to movement between states of sexually intact beef cattle 18 months of age or older and dairy cattle of any age. Feeder cattle and movements of any class of livestock within a state are not subject to the ADT program and are not required by federal law to be identified with electronic ID. That distinction matters: if you are moving animals entirely within Utah, state rules — not the federal RFID mandate — control your identification obligations. You can learn more about the full scope of those intrastate requirements in our guide to transporting livestock laws in Utah.

Important Note: The federal EID rule covers cattle and bison only. Horses, sheep, goats, swine, and cervids are governed by separate species-specific identification rules at both the federal and state level. Do not assume that compliance for one species means compliance for another.

To support implementation, USDA has continued to prioritize funding to offer no-cost electronic IDs for cattle moving interstate, an initiative aimed at reducing the financial burden on producers and encouraging compliance. Contact the UDAF Division of Animal Health or your local USDA-APHIS Veterinary Services office to ask about tag availability in Utah.

Which Livestock Can Use a Microchip as Official Identification in Utah

Utah’s Rule R58-1-3 sets out the official identification devices and methods recognized by the state. Whether a microchip qualifies depends entirely on the species involved.

Equines (horses, mules, donkeys): Equidae may be imported into Utah when accompanied by an official Certificate of Veterinary Inspection, and equines shall be accompanied by a brand inspection or proof of ownership and be officially identified by 9 CFR 86. Under 9 CFR 86, an ISO-compliant microchip is a recognized form of official identification for equines. The USDA 840-ID Official Microchip can be used in all equines, goats, sheep, alpaca, llama, elk, whitetail and other deer.

Sheep and goats: Sheep and goats required to be officially identified for interstate movement may use electronic implants when accompanied by a certificate or owner statement that includes the electronic implant numbers and the name of the chip manufacturer, or official ear tags approved for use in the Scrapie Flock Certification Program, or USDA backtags when moving directly to slaughter. Utah’s intrastate rule under R58-2 also requires that sheep and goats moving within Utah upon change of ownership comply with federal Scrapie identification requirements under 9 CFR Part 79.

Captive cervids (deer, elk): Captive cervids required to be officially identified for interstate movement may use a microchip placed in the right ear. This is one of the clearest species-specific microchip authorizations in Utah’s rules.

Swine: Swine may be shipped into Utah if they are accompanied by an approved Certificate of Veterinary Inspection and have individual official identification such as an RFID or NUES tag. A subcutaneous microchip is not listed as an approved form of official ID for swine under Utah’s current import rules — an RFID ear tag or NUES tag is required.

Cattle and bison: As described above, the 840 RFID ear tag is the required official ID for covered cattle and bison moving interstate. Implanted microchips do not satisfy this requirement for these species. If you raise goats in Utah, our separate guide on goat ownership laws in Utah covers additional state-level requirements beyond identification.

Species	Microchip Qualifies as Official ID?	Primary ID Method Required
Cattle & Bison	No	840 RFID ear tag (EID)
Equines	Yes (ISO-compliant)	Microchip or brand + CVI
Sheep & Goats	Yes (with certificate/owner statement)	Electronic implant or official ear tag
Captive Cervids	Yes (right ear placement)	Microchip in right ear
Swine	No	RFID ear tag or NUES tag

When a Microchip Qualifies for Interstate Movement in Utah

Moving animals across state lines triggers a separate and stricter set of requirements than intrastate movement. For species where a microchip can serve as official ID, there are specific conditions that must be met before that chip is recognized by the receiving state.

For equines entering Utah, equidae may be imported into Utah when accompanied by an official Certificate of Veterinary Inspection or an electronic Extended Equine Certificate of Veterinary Inspection created by a platform approved by the department. The microchip number must appear on that certificate. Equines shall also be tested for Equine Infectious Anemia (EIA) via AGID or ELISA test within one year before entry to Utah, although a nursing foal less than six months old accompanied by its EIA-negative dam is exempt from the test requirement.

For sheep and goats, the microchip alone is not enough. Sheep and goats entering Utah shall comply with federal Scrapie identification requirements as listed in 9 CFR 79. That means the microchip number must be linked to your premises ID and recorded in the National Scrapie Database. To use an 840 microchip for horses, deer, elk, alpaca, llama, and other livestock, you must have a Premises ID Number; for goats and sheep, you must have both a Premises ID Number and a Flock (Scrapie) ID Number.

For captive cervids, Utah’s rules allow a microchip placed in the right ear as official ID for interstate movement, but the accompanying paperwork — typically a Certificate of Veterinary Inspection — must document the chip number and manufacturer. Movement of cervids is also subject to chronic wasting disease (CWD) requirements that operate independently of the identification rules.

For producers in neighboring states sending animals into Utah, it is worth reviewing how identification rules compare. Our articles on transporting livestock laws in Idaho and transporting livestock laws in Colorado outline the requirements on either side of Utah’s borders.

Pro Tip: Always confirm that the receiving state accepts a microchip as official ID before shipping. Even if Utah recognizes a chip for a given species, the destination state may require a different form of identification — and the sending state’s rules govern what goes on the Certificate of Veterinary Inspection.

Approved Microchip Standards and Placement by Species in Utah

Not every microchip is an approved official ID device. Utah defers to USDA-APHIS standards, which means the chip must meet specific technical and numbering requirements to count for official purposes.

The governing standard for official microchips is the USDA 840-ID chip. The “840” chips are used for official USDA identification to comply with USDA-APHIS and Scrapie regulations. The chip numbers begin with the official United States country code of 840. Any chip that does not start with 840 is not recognized as official USDA identification — this includes many standard ISO pet microchips that use different country codes.

Placement requirements vary by species:

• Equines: ISO-compliant microchips are typically implanted in the nuchal ligament area of the neck (left side of the neck at the base of the mane). This location is the international standard for equine microchipping and is where veterinarians and inspectors will scan first.
• Sheep and goats: There are restrictions on the use of implantable devices for sheep and goats; refer to the National Scrapie Eradication Program Standards for full details. In practice, implants are typically placed in the ear or the tail web area per APHIS program guidance.
• Captive cervids: The microchip must be placed in the right ear. This is a Utah-specific placement requirement for captive deer and elk — not the neck or tail web used in other species.

For EID technologies used in official ear tags, both HDX (half-duplex) and FDX (full-duplex) low-frequency ear tags meet U.S. standards for official EID, and either is acceptable for official purposes. When choosing between HDX and FDX, match the tag format to your existing reader equipment to avoid scanning incompatibility in the field.

For cattle and bison ear tags specifically, approved tags must be tamper-resistant, have a high retention rate of at least 99%, and start with the three numbers 840 — the ISO code for the United States. RFID tags are recommended to be placed in the left ear.

Registering a Livestock Microchip in Utah

Implanting a chip is only the first step. For a microchip to function as official identification in Utah, it must be registered and linked to your premises before the animal moves or changes ownership.

The registration process starts with obtaining a Premises Identification Number (PIN). Official tags display the 15-digit AIN (starting with 840), the official ear tag shield, and “Unlawful to Remove,” and a PIN is required to purchase 840 tags. To get your PIN in Utah, contact the UDAF Division of Animal Health at their Salt Lake City office or reach out through the USDA-APHIS state office.

For sheep and goat producers, the registration process has an additional layer. For goats and sheep, you must have both a Premises ID Number and a Flock (Scrapie) ID Number. To request official sheep and goat tags, a flock or premises ID, or both, call 1-866-USDA-Tag (866-873-2824). Once you have both numbers, you can order approved 840 microchips from APHIS-approved vendors and the chip numbers will be linked to your flock record in the National Scrapie Database.

Here is a step-by-step overview of the registration process for most species:

1. Obtain your Premises ID Number (PIN) — Contact UDAF Division of Animal Health or USDA-APHIS Veterinary Services in Utah.
2. For sheep and goats, also obtain a Scrapie Flock ID — Call 1-866-USDA-Tag (866-873-2824).
3. Purchase approved 840 microchips from a USDA-approved vendor — 840 microchip orders cannot ship until Flock and/or Premises IDs are verified.
4. Have a licensed veterinarian implant the chip — Document the chip number, placement location, and date of implantation.
5. Record the chip number on all movement documents — Certificates of Veterinary Inspection, owner statements, and any brand inspection paperwork must include the chip number and chip manufacturer.
6. Retain records — Federal rules require records to be provided to USDA within 48 hours of receiving a request, and the person or entity who distributes official ID devices must enter distribution records into a state or federal database.

Microchipping as Proof of Ownership in Utah

A microchip that meets official ID standards does more than satisfy a movement requirement — it can also serve as evidence of ownership in a dispute or theft investigation. Utah’s brand inspection system under Title 4, Chapter 24 of the Utah Code is the primary tool for establishing livestock ownership, but electronic identification increasingly supplements that system.

For equines, equines shall be accompanied by a brand inspection or proof of ownership and be officially identified by 9 CFR 86. A microchip number recorded on a Certificate of Veterinary Inspection or a brand inspection certificate directly links an animal to its registered owner. If a horse is stolen and later recovered, the chip number — matched against the chip manufacturer’s registry and the USDA premises database — provides a verifiable ownership trail that a brand alone cannot always supply.

For sheep, goats, and camelids, the scrapie identification system creates a parallel ownership record. Sheep and goats entering Utah shall comply with federal Scrapie identification requirements as listed in 9 CFR 79. Because the National Scrapie Database links chip numbers to a specific flock ID and premises, a chip implanted under this program ties the animal back to the producer of origin — useful evidence in a theft or ownership dispute.

For captive cervids, the right-ear microchip requirement under Utah’s rules creates a species-specific ownership record that is especially important given the strict regulations around cervid possession and movement in Utah. Any elk or deer you hold under a captive wildlife permit should have its chip number recorded in your permit documentation.

It is worth noting that a microchip alone does not replace a brand inspection for horses or cattle in Utah. Utah horses returning to Utah as part of a commuter livestock shipment are exempted from the Certificate of Veterinary Inspection requirements; however, a brand inspection or valid Utah horse travel permit and a negative EIA test within one year are still required. The chip and the brand inspection work together — neither fully replaces the other.

Pro Tip: Keep a written record of every chip number, the date of implantation, the veterinarian who performed the procedure, and the chip manufacturer. Store a copy off-premises. If an animal is stolen or strays, this documentation is what law enforcement and UDAF will need to verify your ownership claim.

For producers who also keep backyard poultry, chickens, or other non-traditional livestock, Utah has separate identification and ownership rules that apply. Our guides on backyard chicken laws in Utah and beekeeping laws in Utah cover those requirements in detail. If you ship livestock to other states, our resources on transporting livestock laws in Missouri, transporting livestock laws in Oklahoma, and transporting livestock laws in North Carolina can help you understand what receiving states expect when your animals arrive.

Utah’s livestock microchipping framework rewards producers who plan ahead. Knowing which species accept a chip as official ID, registering your premises before you need to move animals, and pairing every chip with the correct paperwork keeps you compliant under both state Rule R58 and the federal ADT program — and gives you a defensible ownership record if something goes wrong.
