Microchips

If you own a horse or pony with a microchip but without passport, this page helps you to find the original passport issuing organization to apply for a duplicate passport.
A duplicate equine passport can only be issued by the oganization that issued the original passport.

Microchip numbers are registered by country; below are the web sites to find which organzation in a country issued the passport, based on the microchip number.
The links are followed by a list of countrycodes which should correspond with the first 3 digits of the microchip number.

For horses with an Irish (372) registration you need to contact the registering studbook in Ireland.
Passport issuing organizations (PIOs) outside Ireland are not allowed to make replacement equine passports for horses born in Ireland.
You find the issuing organization by the chipnumber or lifenumber of the horse: every Irish  elk Iers PIO has an own set of life numbers from 372001 to 372414 with according microchip numbers.
You find these numbers here. If the PIO cannot help you, mail to HorseID@agriculture.gov.ie of the Department of Agriculture for help.
