Private Mail Centers

NAICS 561431 · Administrative and Support Services · SBA size standard: $19 million average annual receipts

Private mail centers provide mailbox rentals, package acceptance, shipping, copying, notary and related services. For a center that rents post office boxes, accepts deliveries, packs and ships parcels, the specialists turn customer requests into tracked orders, orders into daily shipping manifests and label runs, and manifests into carrier handoffs and inventory reorders. Pricing, carrier contracts and notary seals stay with the owner.
