Cattle Passport Rules: The 27-Day Window Explained

Every calf in the UK needs a passport applied for within 27 days of birth. Miss it, and the animal carries the mark for life. Here is exactly what the rule means, what counts as day one, and what happens the day after day 27.

Quick answer

An application for a cattle passport must be received by BCMS within 27 days of the calf's birth, with the day of birth counting as day one. Miss the window and BCMS will not issue a passport. Instead you get a CPP35 notice of registration, and the animal is permanently barred from the food chain and restricted from moving alive except under a movement licence to a BSE sampling site, a knacker's yard or hunt kennels.

What does the 27-day rule actually say?

The Cattle Passports Order 1996 sets the deadline: an application for a cattle passport has to reach the British Cattle Movement Service within 27 days of the calf being born. That is 27 days for the paperwork to arrive, not 27 days to post it. The calf's date of birth is day one, so a calf born on the 1st of the month needs its application in by the 27th, not the 28th.

There is one exception worth knowing even if it rarely applies to you: bison get 7 days, not 27, because of a separate identification regime. Everything else in this guide is about cattle.

Who has to apply, and how

The keeper of the holding where the calf was born is responsible for the application. In practice this usually happens through CTS Online, by post, or through farm software that files it on your behalf. Whichever route you use, the clock runs from birth, not from when you got round to filling in the form.

What happens if you miss the deadline?

Nothing dramatic happens on day 28. No letter arrives, no fine lands on the mat. What happens is quieter and more permanent: BCMS simply will not issue a passport for that animal. Instead, you get a CPP35 notice of registration, which puts the calf on the Cattle Tracing System without the rights a passport carries.

That difference matters more than it sounds. An animal registered this way:

In plain terms: a calf without a passport is an animal you can raise but can never sell. For a beef or dairy farm, that is not a paperwork inconvenience, it is a financial one.

Worth knowingIf a passport is refused, an unpassported animal already born can sometimes be issued a passport later, but only after vet-administered DNA parentage testing confirms its dam and sire. That costs real money and takes real time, and it is the exact scenario the 27-day rule exists to make unnecessary.

Can you appeal a late passport application?

Yes, in principle. BCMS will consider an appeal if there were exceptional circumstances that stopped you applying in time. In practice, the bar is set high and interpreted narrowly. A busy calving week, a lost form, or simply forgetting are not exceptional circumstances, they are the ordinary texture of running a farm, and BCMS treats them that way. Appeals succeed when something genuinely outside your control happened, such as a documented postal failure or a medical emergency, not when the farm was simply stretched thin.

The honest advice here is not "appeal and hope." It is to treat the 27-day window as non-negotiable and build a process that cannot let it slip, because the appeal route is a last resort, not a safety net.

Why do farmers actually miss the 27-day deadline?

It is rarely carelessness. Calving season is exactly when a farm has the least spare attention to give to paperwork, and the passport application is easy to lose track of among everything else happening in the yard. The most common ways it slips:

How can you make sure you never miss it?

The rule itself will not change with the move from BCMS to the Livestock Information Service, so the discipline still matters after the switch. What can change is how much of the tracking is left to memory. FarmHQ starts the clock the moment a calving is recorded, whether that is typed in or said out loud from the calving pen, and drafts the passport application against the actual birth date so the 27-day window is being watched from day one, not remembered on day twenty-five.

What do farmers actually ask?

What is the deadline for a cattle passport application?

The application must be received by BCMS within 27 days of the calf's birth. The day of birth counts as day one. For bison, the deadline is 7 days, not 27.

What happens if I miss the 27-day deadline?

BCMS will not issue a passport. Instead you get a CPP35 notice of registration, which registers the calf on the Cattle Tracing System but carries permanent restrictions: the animal can never enter the food chain, and it cannot move alive from your holding except under a movement licence to a BSE sampling site, a knacker's yard or hunt kennels.

Can a late cattle passport application be appealed?

Yes, but only on genuinely exceptional circumstances that prevented you applying in time, and BCMS interprets these narrowly. A busy calving season or an administrative slip is very unlikely to succeed.

Does the 27-day rule change when LIS replaces BCMS?

No. The 27-day statutory window is set by the Cattle Passports Order, not by which IT system processes the application. It stays in force as England migrates from BCMS/CTS to the Livestock Information Service.
