This isn't a conventional ZIP code with defined boundaries. It exists as a service point for customers who choose PO Box delivery over street addresses. The facility serves both Key West and Stock Island residents, indicated by the alternate city names associated with the designation. While 222 ZIP+4 records reference Whitehead Street carrier routes, these belong to neighboring 33040, the standard street delivery ZIP that actually covers Key West's residential and commercial districts.
The PO Box concentration here reflects island lifestyle patterns rather than service limitations. Second homeowners and seasonal residents often maintain boxes year-round even when they're not on the island, ensuring mail continuity regardless of occupancy. Businesses operating from multiple Keys locations also concentrate their correspondence here. The 235 business-specific box assignments suggest commercial adoption exceeds typical residential patterns.
Key West's postal infrastructure splits delivery between this PO Box facility and the street carrier routes of 33040. The overlap creates an unusual situation where the same Whitehead Street address might appear in both ZIPs depending on delivery method. This dual-ZIP arrangement is common in resort communities where mail volume and seasonal population swings require specialized service structures separate from geographic coverage.
Whitehead Street is Key West's main north-south artery running from the Gulf to the Atlantic. Its appearance in 33041's ZIP+4 records is administrative reference rather than actual delivery territory, since carrier routes operate under ZIP 33040.
ZIP Code 33041 supports both business and residential activity. According to the Business Census (2024), there are 16 business establishments, employing about 175 people with an annual payroll of $8,645,000.
