While this is technically a PO Box-only ZIP code, it doesn't mean the area lacks street delivery. Residents and businesses in this part of Center City receive their standard mail through the neighboring ZIP 19107, which provides carrier delivery for the same geographic area. The 91 businesses using 19105 PO Boxes likely do so for mail volume, security, or branding reasons rather than necessity.
The street addresses concentrate heavily on Arch Street, one of Philadelphia's original east-west corridors named by William Penn himself. The nearly exclusive focus on this single street suggests the PO Box facility serves a specific downtown block rather than a broader area.
