Why is a microchip important and how does it work for pet travel?

The reasons microchipping matters for pet travel and how ISO and AVID microchips work.

Microchipping your pet is crucial for several important reasons:

  • Permanent Identification: Unlike collars and tags that can break or fall off, microchips provide permanent identification that should last for your pet's lifetime.

  • Reunification: Microchips significantly increase the chances of being reunited with your lost pet. When a lost pet is found, shelters and veterinarians routinely scan for microchips.

  • Proof of Ownership: A registered microchip can help establish proof of ownership in case of pet theft or disputes.

  • Travel Requirements: Many countries require pets to have microchips for international travel, making them essential for pet passports and proof of good health, immunizations, and parasite treatments.

  • Peace of Mind: Knowing your pet has permanent identification provides reassurance that if they ever get lost, there's a reliable way for them to be identified and returned home.

The microchipping procedure is quick, safe, and relatively painless - similar to a routine vaccination. The tiny chip (about the size of a grain of rice) is inserted under your pet's skin, typically between the shoulder blades, and contains a unique identification number that can be read by a scanner.

An ISO microchip, the most commonly accepted for international travel, is a unique 14 or 15 digit number. This type of microchip can be read by internationally standard scanners.

An AVID microchip, less common and most often found in the US, is a unique 9 digit number. This type of microchip cannot be read by an internationally standard scanner and requires a special scanner.

Some jurisdictions accept AVID microchips, but most do not and require an ISO microchip.

Remember: A microchip is only effective if the registration information is kept current. Always update your contact details if you move or change phone numbers.

Requirements vary by airline, route, and destination — always confirm current rules with your airline and the destination's official animal import authority; final acceptance rests with them.
