Because of the diversity of chips and their different modes of operation, some models of chip cannot be read by some of the currently available readers. The Realtrace, PetScan V8, and the Halo will read A& B, while the Universal Scanner will read all chips used in animals worldwide.
The following notes should enable you to accurately determine the type of chip injected into the animal and to interpret the data, if they comply with the ISO standard i.e. have 15 digits.
If the chip number consists of 10 digits and letters:
• This is an FDXA chip.
If the chip number consists of 15 digits:
• This is an ISO chip (FDXB).
As for the chip number’s structure, under the ISO it was originally intended that the first three digits would correspond to the international country code:
However, this regulation is changing.
For example, Great Britain (country code 826) has abandoned its initial coding and has decided to provide vets with chips coded as follows:
3 digits 12 digits
ICAR (International Committee for Animal Recording) is an international body whose responsibilities include checking that RFID products offered by companies (manufacturers and distributors) comply with ISO standard 11784/85. This body issues a manufacturer code after the product has been checked by an approved laboratory. Trovan's manufacturer code is 956, RealTrace (in France) use 936.. This can be used at the beginning of the chip’s code instead of a country code, or it can follow it.
Chip for Chile or Mexico: 939 XXXXXXXXXXXX
Chip for Switzerland: 7560939 XXXXXXXX
In France, the chip coding definition conforms with the ISO standard and was imposed by decree in 2003.
3 digits 2 digits 2 digits 8 digits
250 26 XX XXXXXXXX
- 250 is the ISO country code for France, Great Britain is 826.
- 26 is the species code, in accordance with the Ministry of Agriculture’s coding definitions.
26 = domestic carnivores 25 = equines 22 = exotic pets and wild animals
- the next two digits are the manufacturer number assigned by the Ministry of Agriculture.
When looking at a chip number we recommend that you:
Read the first three digits.
If the number made by the first three digits is between 900 and 985, this is not the country code but the manufacturer code issued by ICAR. If the number is below 900, it is probably the country code.
Finally, please note that you can obtain information on chips by connecting to the database https://www.europetnet.com
There are some concerns about the 900... prefix, this is a default code used by multiple manufacturers and traceability has proved to be an issue for more informaation on this click here).
However, you will have either direct information on the animal's country of origin (if the chip includes the country code) or indirect information through "europetnet" (if the first three digits indicate the manufacturer and they have transmitted the information to Europetnet).
The identification of domestic animals is a regulatory obligation. This rule has gradually been extended to all domestic carnivores (dog, cat, ferret).
- in France: Under the laws of January 6, 1999 and May 17, 2011, the identification of dogs and cats is compulsory for:
- all transfers (sale or gift)
- all dogs older than four months born after January 1999
- all cats older than 7 months, born after 1 January 2012
- in Europe
