Fresno ZIP Codes & Area Codes at a Glance

Fresno ZIP Code Directory

The table below lists major Fresno ZIP codes with the neighborhood or district each covers, the telephone area code that serves it, and the county it falls in.

Beyond the neighborhoods listed above, Fresno 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 Fresno. Mail sorted to the correct ZIP+4 moves faster and is less likely to be delayed or returned.

How Fresno 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 Fresno, the 559 area code covers 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 Fresno area code guide.

Because California uses 10-digit dialing, always dial the area code plus the seven-digit number when calling a Fresno 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 Fresno

In this agricultural hub, watch for fake farm-labor and job-recruitment scams, along with utility-shutoff robocalls demanding immediate payment. Across Fresno 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 Fresno 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.
