## Abstract

We are adopting as a final rule, with several changes, an interim rule that, among other things, amended the regulations to allow for the use of additional numbering systems for purposes of animal and premises identification. As amended by this document, the rule recognizes additional numbering systems for the identification of animals in interstate commerce and State/Tribe/Federal/industry cooperative disease control and eradication programs. Additionally, the rule amends the regulations to authorize the use of a numbering system to identify premises where animals are managed or held. These regulatory changes are necessary to allow the use, for official purposes, of the new numbering systems in the National Animal Identification System. Use of the new numbering systems is not required by this final rule.
