Mailboxes x Mastercard FAQs

Frequently asked questions about our service and the competition. If you still need help, contact us here.

  • Other carriers may charge you for the size of your actual package — not just the weight. Mailboxes ditched this pricing model last year and never looked back.

    Now, when you ship with us, you only pay for the weight of your package, not the size of the box it comes in.

  • Yes! Dimensional weight charges are gone across the board. All packages are now priced by actual weight.

  • Nope! Just keep shipping as usual. We’ll handle the rest.

  • Still charged by actual weight.

    Note: if any dimension is 36” or greater, transit may take up to 72 hours longer to arrive.

  • Dimensional weight charges were officially removed starting August 18th, 2025.
