These codes serve as a crucial identifier for mail delivery, enabling the efficient and accurate distribution of correspondence.

The first three digits of a San Jose postal code represent the Sectional Center Facility (SCF) responsible for processing mail within a specific geographical area. The last two digits denote the Delivery Unit (DU), which refers to a particular post office or carrier route responsible for delivering mail to individual addresses.
