Here is a list of common MicroChip formats so that you know what to look for:

  • 15 digit number = e.g. 977200000000000
  • 10 digit number - e.g. 111111112A
  • 9/13 digit number - e.g. AVID*012*345*378
The MicroChip number will often be listed under a barcode on official paperwork. The number may also have references to ISO, FDXA, FDXB, FECAVA.

There are quite a few places that you might find the MicroChip number:
  • A certificate from the pet MicroChip database
  • Travel documents - it will often be listed as 'Transponder Code' in any travel documents
  • Pet insurance documentation
  • Your pet's veterinary records
If you cannot find the number yourself the following might help:
  • Contact your usual vet as they may have recorded the number on their client records
  • Contact the implanter of the MicroChip, if not your usual vet
  • Take your pet to be scanned at your local vet, rescue centre or dog warden service
If you call our amendments line we are able to search for your pet's details, but as there are multiple databases in the UK it will help to have the MicroChip number. We can only locate the record if already registered in your details on our database, if you are wanting to the transfer the record to yourself you will need the MicroChip number.

If you have the MicroChip number then we can help direct you to the appropriate database if the pet is not registered with the UK PETtrac MicroChip Database.
