Finding the right postal code for Buffalo, New York doesn't have to be confusing. The city uses ZIP codes ranging from 14201 to 14225 for its core neighborhoods, downtown business districts, and immediate residential zones.
If you're mailing a package, setting up billing software, or looking up delivery routes, knowing the exact ZIP code prevents costly shipping delays and mail misroutes.
Let's break down how Buffalo's postal system is organized, examine the complete neighborhood list, and clear up common misconceptions about local mailing zones.
Overview of Buffalo ZIP Codes
The United States Postal Service (USPS) manages Buffalo's mail network through sectional center facilities that route all incoming and outgoing mail for Western New York. Additional insights regarding the matter are explored by Associated Press.
Unlike smaller towns that share a single postal code, Buffalo is split into dozens of distinct delivery zones. These codes help postal carriers sort mail by street grids, carrier routes, and high-density commercial blocks.
- Downtown Core: 14202, 14203
- West Side & Black Rock: 14201, 14213
- North Buffalo & University Heights: 14216, 14214
- South Buffalo: 14220
- East Side & Kaisertown: 14208, 14211, 14212, 14215
Using a generalized city-level address without a proper ZIP+4 or correct five-digit code often results in automated sorting halts at the regional processing and distribution center.

Suburban ZIP Codes Near Buffalo
People often confuse Buffalo city limits with the surrounding Erie County towns. While these suburbs use Buffalo mailing addresses, they operate under distinct municipal boundaries and postal codes:
- Amherst: 14221, 14226, 14228
- Cheektowaga: 14225, 14227
- Tonawanda: 14150
- West Seneca: 14224

If you're shipping freight or filling out official government forms, make sure you don't mix up town postal codes with city codes, as utility districts and emergency services rely strictly on municipal boundaries.
Common Mailing Mistakes to Avoid
Mailing errors can add days to delivery times. Keep these practical tips in mind when addressing mail to the Buffalo area:
- Check directional prefixes: Buffalo features streets with North, South, East, and West designations (such as West Ferry Street vs. East Ferry Street). Swapping these results in immediate misdelivery.
- Don't rely on city names alone: Cities like Cheektowaga and West Seneca often use Buffalo mailing addresses, but writing the exact town name alongside the correct ZIP code ensures accurate sorting.
- Verify street name changes: Several historic streets have updated names or alternative designations used by local delivery drivers. Always check digital mapping tools if you're unsure.
