MADISON, Wis. – Wisconsin is again accepting orders for no cost 840 radio frequency identification (RFID) official identification tags provided by USDA. Currently, there is a limited supply of these tags, and they are anticipated to be available until September 30, 2025, or while supplies last. In Wisconsin, these tags are available for markets and dealers, directly to producers, and to veterinarians for use with their clients’ animals, and are intended for use in cattle and bison only.

Tags can be ordered in multiples of 1,000. Currently, there is a 5,000-tag limit per order due to limited supply. Other important details include:

For producers, tags are for use only with your own animals. Tags should not be shared, sold, or used at other farms. For markets, dealers, and veterinarians, RFID tags are available to apply to customers’ and clients’ animals. Note that records are required. For markets, dealers, and producers, white button tags are available. For veterinarians, white button tags are available, as well as orange button tags used for identification when vaccinating against brucellosis. Although 840 RFID tags are required for brucellosis vaccination, orange tags are not required; however, the orange tags can only be used for this purpose.

Taggers are the responsibility of the person ordering the tags. Taggers can be ordered directly from the manufacturers or their distributors. It is recommended to use a tagger from the same manufacturer as the tags.
