A Historical Tapestry: The Evolution of San Diego's Postal Codes

The history of San Diego's postal codes is inextricably linked to the city's growth and development. The first post office in San Diego was established in 1850, assigning a single postal code (92101) to the entire city.

As San Diego expanded, the need arose for a more granular system of postal codes. In 1963, the U.S. Postal Service implemented the five-digit ZIP code system, assigning unique identifiers to each neighborhood.

The subsequent decades witnessed several revisions and expansions to the San Diego postal code system. In 1983, the ZIP+4 was introduced, adding an additional four digits to further refine mail delivery. And in 2003, the Postal Service introduced the ZIP+9, which further augmented the level of precision by indicating the specific delivery point within a given address.
