Yes — 94401 (San Mateo, California, San Mateo County) is inside the coverage network, and requests from this ZIP are routed to licensed electrical contractors working the San Mateo area. Give the dispatcher the ZIP and the street so they can confirm the visit window.
Do you handle both homes and small businesses?

Is 24/7 emergency service available for 94401?
