Westamerica Bancorporation operates as a holding company for Westamerica Bank, a regional community bank with over 90 branches and 2 trust offices in 21 Northern and Central California counties.

As one of the leading financial institutions in the Northern and Central California areas, Westamerica Bancorporation recognizes its responsibility not only to provide the highest quality banking services to the citizens of our communities, but also to improve the quality of life of the communities we serve.
