The ZIP Code Boundary Review Process requires any municipality or community group seeking a ZIP code change to submit the request in writing to the USPS district manager who is responsible for the area along with any rationale and justification.

A United States postal code, for example, might be either five digits or five digits followed a hyphen (dash) and another four digits (12345-1234). If you are validating US postal codes, allow for both conditions. The following rule validates a field that can be five digits, five digits + dash + 4 digits, or blank.

Also called ?plus-four codes?, ?add-on codes?, or ?add-ons?, the ZIP+4 code starts with the standard five-digit ZIP Code. The four extra numbers are added after a hyphen to complete the ZIP+4. So what do the extra numbers mean? These last 4 digits represent specific delivery routes within delivery areas.

ZIP & ZIP+4 United States ZIP codes are five numerical digits long. ZIP+4 codes, also known as add-on or plus-four codes, include four additional digits that identify a geographic segment within a ZIP code delivery area. The first digit in a ZIP code represents a defined group of U.S. states.

Decoding the Code "0" represents the northeastern U.S. and "9" is used for the western states (see list below). The next two digits identify a commonly linked transportation region and the last two digits pinpoint the correct processing center and post office.

The first number in the code represents a general geographic area of the nation, ?0? in the East, moving to ?9? in the West. The next two numbers represent regional areas, and the final two identify specific Post Offices.

ZIP is an acronym for Zone Improvement Plan. However, the USPS intentionally chose the acronym to indicate that mail travels more quickly when senders mark the postal code on their packages and envelopes. It makes sense that the term ZIP code would be related to being zippy, which means ?lively? or ?peppy.?
