Common Mistakes When Addressing Mail to Western New York
Mailing errors often happen when people confuse city limits with postal boundaries. For instance, parts of Cheektowaga, Amherst, and Tonawanda share postal prefixes with Buffalo because mail delivery routes cross municipal lines.
If you write "Buffalo" on an envelope that belongs in Amherst or Cheektowaga, sorting machines rely strictly on the five-digit code to prevent misrouting. Always verify the specific numerical code rather than assuming the municipal name matches the postal designation. For official verification of zoning changes or boundary maps, consult the U.S. Census Bureau.
