  • The ZIP was introduced to the postal system before October 2004 and maintains P-classification (PO Box only).

  • Border location in El Paso County suggests the facility may serve cross-border mail needs and international commerce.

The PO Box System

The ZIP has no residential population, no land area designated for carrier routes, and no street delivery infrastructure. What it does have is a post office that processes mail for people across the broader El Paso metro area who prefer or require PO Box service. This pattern appears frequently in border cities where cross-border commerce, international mail forwarding, and privacy needs drive PO Box demand beyond what local street addresses would suggest.

Geographic Context

The facility sits within the 79910 ZIP code's geographic boundaries, near the Cielo Vista neighborhoods. Three nearby communities—Cielo Vista North, Cielo Vista East, and Cielo Vista South—all sit within a mile of the post office location. These are predominantly Hispanic neighborhoods (over 80% across the area) that reflect El Paso's binational character. Residents in these areas get home delivery through their own ZIP codes but may maintain boxes at 88521 for business mail, package delivery from carriers that don't deliver to all addresses, or correspondence that crosses the international border regularly.

Understanding Border Post Offices

Border cities like El Paso maintain PO Box facilities that serve populations well beyond the immediate neighborhood. The administrative separation between street delivery ZIPs and PO Box-only designations reflects USPS's operational structure more than community geography. For customers, the distinction matters only when filling out forms—mail gets delivered either way.

Street Name Patterns

No street delivery exists in this ZIP code. It operates exclusively as a PO Box facility with no carrier routes or delivery addresses.
