About the Cambridge branch
The Cambridge Post Office is a small U.S. Postal Service branch at 265 Cambridge Avenue, a block off California Avenue. USPS lists it as Cambridge, ZIP code 94306; OpenStreetMap calls it the Cambridge Branch. It is the closest post office to the California Avenue district and a short walk from the California Avenue Caltrain station. USPS lists street parking, which carries time limits here. The USPS page also gives the national line, 1-800-ASK-USPS, plus a TTY line at 877-889-2457.
The branch does not offer passports. The Palo Alto main post office on East Bayshore Road takes passport appointments and has a kiosk open into the evening. Downtown, the Hamilton Avenue post office keeps Saturday counter hours, which this branch does not. The Stanford post office in White Plaza was scheduled to close on October 31, 2026.
