Beyond the neighborhoods listed above, Oakland also has ZIP codes reserved for post-office boxes, large-volume business mailers, universities, and government facilities that do not correspond to a single residential district. When you are unsure which code to use, the USPS ZIP Code Lookup confirms the exact ZIP for any street address, while the area code shown in each row indicates the telephone prefix that most commonly serves that part of Oakland. Mail sorted to the correct ZIP+4 moves faster and is less likely to be delayed or returned.

How Oakland ZIP Codes and Area Codes Align

A ZIP code is a postal routing number, while an area code is a telephone routing number, so the two systems do not map one-to-one. In Oakland, the 510, 341 area codes overlap the same territory that dozens of ZIP codes divide up. A single ZIP code can contain phone numbers from more than one area code, and a single area code spans many ZIP codes. For a full breakdown of the telephone side, see the Oakland area code guide.

Because California uses 10-digit dialing, always dial the area code plus the seven-digit number when calling a Oakland line, even locally. When you only have a ZIP code, the directory above is the quickest way to see which area code most likely serves that part of the city.

Postal & Telecom Scam Warnings in Oakland

Watch for fake home-services and utility-shutoff scams, and never share account details with an unsolicited caller claiming to be your bank or PG&E. Across Oakland ZIP codes, watch for USPS “undelivered package” smishing texts that ask you to pay a small redelivery fee, address-change and mail-hold fraud, and area-code spoofing that makes robocalls appear to come from a local Oakland number. The Postal Service never texts you a payment link for a package, and legitimate callers do not demand gift cards or wire transfers. Report mail fraud to the U.S. Postal Inspection Service and unwanted calls to the FTC at reportfraud.ftc.gov.

What area codes serve Oakland?

Oakland is served by the 510, 341 area codes. See the Oakland area code guide for full details.
