Swine producers can now order 840 RFID (radio frequency identification) eartags at www.840swinetags.com—at no cost. Tags are shipped directly from Merck Animal Health to your premises. Tags are available while supplies last. Order your tags now to ensure you have tags available when you need them.
These tags are for use in swine only.
Producers need:
- Your valid premises ID
- Shipping information
- Contact information
- Your sow or show pig count
- Number of tags
If you require assistance locating your premises ID, please contact the Wisconsin Livestock Identification Consortium (WLIC) at 888-808-1910 or visit wiid.org.
Note: RFID tags must be applied using a compatible tag applicator, which is not provided through this program.
About the Swine Identification Initiative
Originally announced in August 2025, this initiative—modeled after the successful no-cost RFID cattle tag program—aims to strengthen national swine disease traceability. While traceability does not prevent disease, it significantly reduces the time needed to respond to outbreaks, helping to limit the number of affected farms and animals. This, in turn, minimizes economic impacts on producers and their communities.
For full program details—including eligibility, ordering instructions, and tag quantity guidelines—visit Swine Identification.
