What Drives Price
Box size is the dominant factor. Small boxes are the least expensive, while large boxes in city centers command the highest rates. Facility location also matters; urban facilities typically charge more due to demand and space costs.
Regional Price Differences
Prices show noticeable variation across regions. In major metropolitan areas in the Northeast or West Coast, small boxes can exceed $15–$25 per month, while many suburban locations in the Midwest or South fall in the $6–$15 range for small boxes. Urban premiums of 20–60% over rural areas are common, driven by overhead and real estate costs.
Real-World Pricing Examples
Assumptions: single user, standard 5″ x 5.5″ box, no forwarding; location varies.

Factors That Affect Price
Contract terms and location influence price; some facilities offer annual prepay discounts, while others bill month-to-month. Accessibility options such as 24/7 access or after-hours slots can add to the monthly cost.
Ways To Save
Compare by ZIP to identify lower rates nearby, as prices can vary widely within the same city. Choose a smaller box if you only need mail intermittently. Bundling services, if available, may reduce per-item costs.
