History of P.A. Zip Codes
The United States Postal Service (USPS) introduced the zip code system in 1963 to improve mail sorting and delivery efficiency. Pennsylvania, being one of the original 13 colonies, was among the first states to adopt the zip code system. The P.A. zip code was designed to divide the state into distinct regions, making it easier to manage mail distribution. Over the years, the zip code system has undergone several changes, with new codes being added and old ones being modified to accommodate the state's growing population.

P.A. zip codes are five-digit codes that identify specific geographic areas within the state. The first digit represents the region, the next two digits represent the sectional center facility, and the final two digits represent the post office or delivery area. For example, the zip code 15213 represents the city of Pittsburgh, with 15 being the region, 21 being the sectional center facility, and 13 being the post office or delivery area.
