    • PMBs provide you with a real street address, which is more professional than a conventional PO Box number
    • PO Boxes rented through USPS can only receive Postal Mail and USPS packages, while PMBs can accept mail and packages from all carriers, including FedEx and UPS
    • PMBs provide package arrival notifications
