Galveston's postal history dates back to the 19th century, when it served as a critical port of entry and commercial hub. The establishment of the ZIP code system in 1963 streamlined the sorting process for the city, which had grown into a complex urban environment with distinct neighborhoods. The introduction of the extra digits, known as ZIP+4, allowed for even more precise localization, down to specific city blocks or high-volume receivers.
