Horse Passports and Microchips: What the Law Asks

In the UK every horse, pony and donkey needs a passport, and in England every one must also be microchipped. When you buy one, tell the Passport Issuing Organisation within 30 days. Ireland has passport rules too. The US has no national horse passport, but states ask for a negative Coggins test and a health certificate to cross state lines.

Why Horses Carry Papers

An identity document links a horse to its owner, its microchip and its health records. That helps reunite stolen or straying horses with their owners, helps vets trace disease, and, in countries where horses can enter the food chain, records whether a horse may be used for food.

The paperwork differs a lot between countries. The UK and Ireland have lifelong passports for every equine; the US and many other countries rely on state or regional health papers for travel. Rules change, so treat this page as a starting point and check with your national authority.

The Law: Rules Differ by Country

Most countries have some form of horse ID or travel paperwork. What it covers, and who issues it, is set nationally, and sometimes by state or region.

England: every horse, pony, donkey, mule and other equine needs a passport, kept with the animal at all times, and every equine must be microchipped by a vet. Apply for a foal's passport before it is 12 months old. Tell the Passport Issuing Organisation (PIO) within 30 days if you buy a horse, or if it dies. Semi-wild ponies on Dartmoor, Exmoor, Wicken Fen and in the New Forest need a passport only if they are enclosed on your land or treated by a vet. Fines are possible (gov.uk).
Scotland and Wales: passports are needed too, under their own regulations, and details can differ. Check gov.scot or gov.wales.
Northern Ireland: every equine needs a lifetime identification document; equines born on or after 1 July 2009 must be microchipped; keep details up to date on the UK Central Equine Database (DAERA).
Ireland: equines need a passport, and the place where they are kept should be registered with the Department of Agriculture, Food and the Marine (DAFM). Check gov.ie.
United States: no national passport. All states require a negative Coggins (equine infectious anemia) test to bring a horse in, and most also want a Certificate of Veterinary Inspection from an accredited vet, usually dated within 30 days. Each state sets its own entry rules, so call the destination state veterinarian's office (USDA APHIS keeps links to state rules).
Elsewhere: Canada (CFIA and your province), Australia (your state or territory agriculture department), New Zealand (Ministry for Primary Industries).

Rules change, so check with your national authority before you buy, sell or travel.

UK Passports in Practice

A UK horse passport is a small booklet issued by a Passport Issuing Organisation, usually a breed society or a specialist ID organization. It describes the horse with a markings diagram, records its microchip number and, for pedigree animals, its breeding.

Keep it with the horse. At home that means on the same premises. When the horse travels, the passport goes too.
Have it ready for the vet. Vets need to see it when they examine or treat a horse.
Buying? Don't hand over money until you have seen the passport, checked that the microchip matches it, and checked the details on the national chip checker. If a seller won't give you the passport, gov.uk says to contact your local trading standards office.
Update it. New owners contact the PIO within 30 days. The PIO updates the Central Equine Database for you.

Microchips and the Central Equine Database

A horse microchip is about the size of a grain of rice and is placed by a vet in the neck. In England it is compulsory for every equine; elsewhere in the UK the rules depend on age and nation.

The UK Central Equine Database links each chip number to a passport. You can check a chip number with the online chip checker. If you find a horse was never chipped, a vet can chip it and you then update the passport with the PIO.

The Food Chain Section

In the UK and the EU, horses can legally enter the human food chain unless they are signed out of it. The passport records that status, and it affects which medicines a vet may use and what must be written down. Once a horse is signed out, it can't be signed back in.

Medicines and your horse's passport: see your vet or a pet supply store with trained staff. Your vet can explain what the food chain section means for your horse's care.

If you buy a horse, you must tell the PIO within 30 days if it is signed out of the food chain. Your vet will talk you through it.

A waterproof document wallet keeps the passport dry in the lorry or trailer. A small lockable document box in the tack room or house keeps it safe at home. A headcollar name plate or tag with your phone number helps if a horse gets loose, and a record book keeps vaccination, farrier and dental dates together.

Travel Papers in the US and Elsewhere

In the US the Coggins test is a blood test for equine infectious anemia, drawn by a vet. States differ on how recent it must be: some want it within 6 or 12 months, others go by the calendar year. Shows, boarding barns and trail rides often ask for one too, even without a state line in sight.

A Certificate of Veterinary Inspection, often called a health certificate, is issued by an accredited vet after examining the horse. Some states accept extended or "passport" certificates for horses that travel often. Ask your vet well before a trip, because test results can take a few days.

In other countries, ask your agriculture authority what papers a horse needs to move, and keep records of ownership and vaccinations even where no passport is required.

Frequently Asked Questions

The paperwork questions people ask most.

Do donkeys and Shetland ponies need passports in the UK?

Yes. Every equine needs one, whatever its size, including donkeys, mules and miniature ponies. In England they must be microchipped as well.

What happens if a horse I'm buying has no passport?

In the UK, don't buy it until the seller sorts it out. A horse passported late is treated as signed out of the food chain. If a seller won't hand over the passport after a sale, contact your local trading standards office.

How long do I have to update the passport after buying a horse?

In England, contact the Passport Issuing Organisation within 30 days. The PIO then updates the Central Equine Database.

Can I microchip my own horse?

No. In the UK only a vet may implant an equine microchip. Your vet can also scan an older horse to see whether it already has one.

Does my horse need a passport in the US?

There is no national passport. To cross state lines, all states want a negative Coggins test and most want a health certificate, each within a set time. Check with the destination state.

Should the passport go with my horse to a show?

In the UK, yes: the passport must travel with the horse. In the US, take your Coggins and health certificate, and check the show's own entry rules too.
