List of ZIP Code prefixes

Each cell in this table contains a three-digit ZIP code prefix, the state where that ZIP code prefix is located, and the name of the United States Postal Service (USPS) Sectional Center Facility (SCF) that serves that ZIP code prefix, which may be in a different state. Each SCF may serve more than one three-digit ZIP code prefix. Each SCF serves local addresses whose five-digit ZIP codes start with the same set of prefixes.

• An asterisk (*) indicates that the listed place name is the "default" place name for all addresses in the prefix, that is, that addresses for all ZIP codes beginning with that three-digit prefix will have that place name in the city portion of the address (example: 23219, 23224, and 23294 will all have "Richmond, Virginia" addresses, even if the mailing address is physically located elsewhere.).
• A dagger (†) indicates that the SCF serving this prefix is in a different state.
• A double dagger (‡) indicates that the prefix was not part of the original set of ZIP Codes when the system was introduced in 1963.
