Introduction to Identification, Registration and Movement of Animals
This section contains information related to the identification, registration and movement (IRM) of animals. The identification and tracing of animals for veterinary purposes is of crucial importance for the control of infectious diseases.
Livestock Identification Prefix Code – End of the Transition Period on 30 June 2025
(updated 30 June 2025)
The prefix code on Northern Ireland livestock tags has changed from ‘UK’ to ‘XI’.
From Monday 30 June 2025 all newborn cattle, sheep and goats in Northern Ireland must only be identified with ‘XI’ prefixed tags.
Unused stocks of ‘UK’ prefixed tags are now obsolete, and keepers should dispose of them, as they will not be able to use them to identify their animals.
There is no requirement to re-identify animals which were identified in Northern Ireland with ‘UK’ tags prior to 30 June 2025, if they are remaining within the UK.
All livestock being exported to continental Europe must be identified with 'XI' tags prior to their export. Any such animals previously tagged with 'UK' tags must be re-identified with ‘XI’ tags. For cattle this must be done under veterinary supervision.
All sheep and goats being exported to Ireland must be identified with 'XI' tags prior to their export. Any such sheep and goats previously tagged with 'UK' tags must be re-identified with ‘XI’ tags, with the re-identification recorded in the flock register. Keepers may wish to consider re-identifying all sheep and goats going to market with ‘XI’ tags to ensure they are eligible for purchase for export.
Cattle identified with ‘UK’ tags prior to 30 June 2025 can still be exported to Ireland without being re-identified with ‘XI’ tags.
This change, which is a legal requirement under EU Animal Health Law, has ensured continued unfettered access (subject to normal export eligibility requirements) to both EU and UK internal markets for our livestock and agri-food products. It will also help prepare for the introduction of bovine electronic identification in the future.
Please see Tag prefix changes Q&A for further details.

Standstill
The 6-day whole-farm standstill restriction no longer applies from Monday 4 March 2013. From this date, animals moved onto a holding will not cause movement restrictions for other animals on the holding. This relaxation will allow livestock to move more freely between holdings.
For disease control and animal welfare purposes an animal cannot move to a market if that animal has been in a market in the last 6 days.
Keepers who move cattle, pigs, goats and sheep must comply with the conditions of the revised general movement licence when moving livestock within Northern Ireland.

Northern Ireland Food Animal Information System (NIFAIS)
NIFAIS will replace APHIS which has been in operation since 1999 and is approaching the end of its natural life span and support contract. The NIFAIS programme was established to procure, develop and implement a new system utilising the most up-to-date technologies which will be flexible, adaptable and future proofed. NIFAIS will build upon the already world leading functionality that APHIS currently delivers and enable DAERA to move forward with new advances in IT.
