Animal Disease Traceability Program Overview

The Animal Disease Traceability (ADT) program is a USDA initiative that applies to all livestock moving interstate. This system incorporates individual animal identification, record keeping and when necessary, record sharing. Although animal disease traceability does not prevent disease, an efficient and accurate traceability system reduces the number of animals and response time involved in a disease investigation. This tool helps reduce the economic impact of a livestock disease outbreak on owners and affected agricultural communities.

Maine Premises Identification Number

Premises Identification is one part of the USDA Animal Disease Traceability (ADT) program. A Premises Identification Number (PIN, also commonly called a "Prem ID") is a unique code that is permanently assigned to a single physical location. PIN registration is administered by each State and plays an important role in an animal disease response event.

The PIN record helps animal health officials quickly and precisely identify the locations of livestock and their potential contacts during an animal disease outbreak. A PIN permanently corresponds to a physical location where livestock are born and housed. If a producer moves their business to a new location, they would register for a new PIN and discontinue using any official ID tags associated with the old PIN and location.

What is premises identification number? +

A premises identification number is a unique code that is assigned to a physical location. Once a premises is established and registered with a identification number it is tied to that physical location permanently so there is no need to obtain a new number each year or re-register. However, since it linked to that physical location the premises identification number will not travel with you if you move and you will need to obtain a new number for your new location. Also, if you raise livestock at multiple locations there will need to be a unique premises identification number for each unique physical location.
