For National Animal
The U.S. Department of Agriculture’s Animal and Plant
Health Inspection Service has published in the
Federal Register a final rule that recognizes additional
numbering systems for identification of animals in
interstate commerce and state/tribal/federal/industry
cooperative disease and eradication programs. It
also recognizes a new standard numbering system to
identify premises where animals are managed or held.
This final rule is based on an interim rule that has
been in place since Nov. 8, 2004, and contains only
minor revisions in response to public comments.
The final rule recognizes animal identification num-
bers (AIN) for the identification of individual animals,
the group/lot identification number (GIN) for the iden-
tification of groups or lots of animals, and the prem-
ises identification number (PIN) for the identification
of premises. The rule also prohibits the removal of
official identification devices and eliminates potential
regulatory obstacles to recognizing emerging tech-
nologies that could offer alternatives to existing animal
identification devices and methods.
APHIS received 16 comments on the interim rule
from producers, producer associations and state
governments. In response to comments received, the
final rule was adjusted in the following manner:
• The definitions for AIN and PIN were clarified to
show that they are “nationally unique” numbers.
The AIN is a unique 15 digit number which is
used for the NAIS and other programs, including breed
registry and performance recording by the livestock
industry. The first three digits of the AIN contain
the country code (840 for the United States). Dur-
ing an interim phase, the use of manufacturer codes
assigned by the International Committee on Animal
Recording or “USA” as the first three digits of the AIN
is also recognized as official identification.
