What is an LID #? Can I use that to purchase 840 tags?


An LID # is a Location Identifier Number. In some cases, 840 tags can be purchased using an LID number, but a Premise ID is more reliable and is sure to work. The LID is assigned for a state-wide tracking system, and is not shared with the federal government. A Premise ID is assigned by the state on behalf of the federal government.


How can I register to receive a Premise ID Number?


Most states have forms to fill out, which are submitted to the state Department of Agriculture or the state’s livestock traceability program. From here, your premise or location is assigned a permanent number which never needs renewed or changed. Some states also have the option to register over the phone.
