Protecting American animal agriculture by safeguarding animal health is vital to the wellbeing of all U. S. citizens. It promotes human health; provides wholesome, reliable, and secure food resources; mitigates national economic threats; and enhances a sustainable environment. Essential to achieving this goal is an efficient and effective animal identification program.

The National Premises Identification Number provides a unique number across the entire United States for locations involved in animal agriculture and links that location to the entity that participates in animal production and/or commerce.

Requests for premises identification numbers received by the California Department of Food and Agriculture shall be maintained in confidence to the extent authorized by law.

An accountholder e-mail is required to request a premises identification number. Call 866-325-5681 if you don't have an e-mail address.
