Microchips for pet identification follow strict numbering standards regulated by international organizations. The most common standard is ISO 11784/11785, which defines the structure and technical requirements for microchips.
Standard 15-digit microchips
Consist of 15 digits.
The first three digits represent the manufacturer or country code.
The remaining digits are a unique identification number assigned to the pet.
8-digit and 9-digit microchips
These microchips are less common, accounting for less than 1% of the market.
They do not comply with ISO standards and may not be readable by all scanners.
The Issue of Counterfeit and Duplicate Microchips
The spread of counterfeit and duplicate microchips poses a serious threat to pet identification:
Counterfeit Microchips
Produced by unauthorized manufacturers without following standards.
May contain incorrect or fake codes, making registration in databases difficult.
Using counterfeit microchips can result in lost pets not being identified.
Duplicate Microchips
Occur when the same identification number is used by different manufacturers or due to registration errors.
Lead to confusion in databases and complications in reuniting lost pets with their owners.
Microchipping is an essential step in ensuring pet safety and identification. Adhering to international standards and avoiding counterfeit chips will increase the chances of reuniting with your pet if it gets lost.
