Understanding ZIP Code Boundaries

ZIP (Zone Improvement Plan) codes were introduced by the United States Postal Service (USPS) in 1963 to improve the efficiency of mail sorting and delivery.

The History of ZIP Codes

Before ZIP codes, mail delivery could be significantly slower due to manual sorting.

The USPS continues to update and refine these codes to adapt to population changes and new developments.
