Due to an increase in population or to the improve postal operations, the US Postal Service® will occasionally add a new ZIP Code or change ZIP Code boundaries.

As of 1963, zip codes' numbers are determined by a few factors: the area, the regional postal facility and the local zone. The first number of the five-digit code signifies the region which the address is located in, a number that grows from the east coast to the west.

?the five-digit ZIP number is a structured code in which the first digit identifies one of ten large areas of the Nation, and the second digit indicates a State, a geographic portion of a heavily populated State, or two or more less populated States.

Because ZIP+4 codes are based on delivery routes, they change when the postal delivery routes are updated by the USPS. That's why ZIP+4 codes can change as often as once a month, since there are several factors that can result in the USPS updating its delivery routes.

The current postal codes in the United States range from 00001 ? 99950. The lowest and highest of these postal codes are both specific to areas in Alaska; The 00001 code is for the N Dillingham area, and the postal code 99950 is for Ketchikan, AK.

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.

Most of the information that changes about a ZIP code is related to the ZIP+4 (the last 4 digits after the primary 5 digit ZIP code) or the number of deliverable addresses. Neither are included in the ZIP code database so updates can be less frequent.
