Equines Entering California through Border Stations

Border station personnel are required to document all horses crossing into California. This includes California horses returning to California. Thus, all horse trailers are required to stop at the border station crossings to provide destination information and required entry documentation. To facilitate prompt, efficient transition through the station, an Equine Only – California Entry Document has been developed. This document can be completed in advance and provided to the border personnel for verification.

Equine owners and transporters are encouraged to download and complete the document for presentation to station personnel.
