The National Uniform Eartagging System employs an eight- or nine-character alphanumeric format, consisting of a two-number State or territory code, followed by two or three letters and four additional numbers. Official APHIS disease control programs may specify which format to employ.

Official animal identification. A device or means of animal identification approved for use under this part by APHIS to uniquely identify individual animals. Examples of approved official animal identification devices are listed in § 55.25 of this chapter. The official animal identification must include a nationally unique animal identification number that adheres to one of the following numbering systems:

(1) National Uniform Eartagging System. The CWD program allows the use of either the eight-character or nine-character format for cervids.

(2) Animal identification number (AIN).

(3) Premises-based number system. The premises-based number system combines an official premises identification number (PIN), as defined in this section, with a producer's livestock production numbering system to provide a unique identification number. The PIN and the production number must both appear on the official tag.

(4) Any other numbering system approved by the Administrator for the identification of animals in commerce.

Premises identification number (PIN). A nationally unique number assigned by a State, Tribal, and/or Federal animal health authority to a premises that is, in the judgment of the State, Tribal, and/or Federal animal health authority, a geographically distinct location from other premises.

The premises identification number may be used in conjunction with a producer's own livestock production numbering system to provide a unique identification number for an animal. It may also be used as a component of a group/lot identification number. The premises identification number may consist of:

(1) The State's two-letter postal abbreviation followed by the premises' assigned number; or

(2) A seven-character alphanumeric code, with the right-most character being a check digit. The check digit number is based upon the ISO 7064 Mod 36/37 check digit algorithm.
