General case

The UELN is a 15-digit alphanumerical number in two-parts.

  1. The first part is the UELN code of the organization managing the horse. It is the international code of the database, which makes unique the UELN of the horse. It is composed of itself by two parts:
    1. 3 numbers for the country of the database which registered the foal at birth (ISO -3166 country code);
    2. 3 numbers for the code of the database where the horse has been registered at birth.
  2. The second part is composed of 9 numbers. It is the horse national identification number given by the stud-book of birth. This horse national identification number can include numbers and characters.

For example: In France, 250001 is the UELN code for SIRE (the national database). Take a horse at random: its national number in the SIRE database is 00155928M. So its UELN number will be 25000100155928M.

Some characteristics:

  • For Thoroughbreds, it was agreed that the 3 numbers for the code of the database were replaced by the alphacode of the country.

For example: In France, 2500FR is the UELN code for SIRE for thoroughbreds, in Ireland 372IRE is the code for Weatherbys for thoroughbreds

  • If the horse national identification number has fewer digits and/or characters than 9, so add zeros between this identification number and the UELN code.

For example, IHB UELN code is 372414. The national number of one of its horses may be 1234567 (only 7 characters). So the UELN number of this horse will be 372414001234567.

  • If the horse national identification number includes special signs like / * or !, find a way of translating this number so that you will only have alpha-numeric characters in the UELN number (each database using such signs can choose its own way of translation).

For example, a UELN code is 121212. A horse national number is 78M/234. The UELN number of this horse may be 1212120078M0234. We add a zero to complete the 2 characters GB and another one before the national number of the thoroughbred.

Case of germany

The particularity of Germany is that there is an existing codification of the organisations. Each organisation has two kind of codes : one for horses born before 2000 and another one for horses born since 2000.

For example : a horse born in Germany and registered at birth by the Rheinisches Pferdestammuch e.V.
