Online Form Available for Federal Premises Identification Registration


As exotic animal diseases such as avian influenza and African swine fever continue to threaten the Missouri livestock industry, the Missouri Department of Agriculture is encouraging producers to create or strengthen biosecurity plans in their holdings. The first step in developing a biosecurity plan is to register for a Federal Site Identification Number (PIN).

A PIN is a unique code permanently assigned to a single physical location. This number can be assigned to places where animals are born, managed, marketed or exhibited. Allied farms and non-producer participants can also register for PINs.

PIN registration is administered by the State of Missouri and allows animal health officials to quickly and accurately identify the whereabouts of animals in the event of an animal health or food safety emergency. Information collected during establishment registration will be used for animal health purposes only. This essential data will provide animal health officials with the necessary contact information in the event of a disease problem.

The Missouri Department of Agriculture accepts free and voluntary registration of premises in the state.

MDA has created an easy-to-use online registration form for federal premises identification. To obtain a PIN online, visit For those who prefer to register by phone, contact MDA’s Animal Health Division at (573) 751-3377.

Once PIN registration is complete and locations have been validated by the Animal Health Division, a PIN card will be mailed to the holder.

If you have already registered for a PIN in the State of Missouri, but have forgotten the number or need to update the premises information, call the Department at (573) 751-3377 .

The Missouri State Fair does not require PINs to show or exhibit livestock.
