Add a ship-from address

Updated October 6, 2026

Where your labels originate. Verified against USPS so the ZIP+4 is always right.

  • Open Addresses from the app header and choose Add address.
  • Enter a nickname (for example Garage or Warehouse 1), the contact name, phone, and the street address.
  • Save. We verify the address against USPS and store the standardized version with its ZIP+4 so labels never fail address checks.
  • Set a default. The default address is pre-selected on every new order; you can switch per order.

Verification said the address could not be found

Double-check the unit or suite number and the ZIP code. New construction can take USPS a few weeks to add. You can still save an unverified address, but carrier rates will be based on the ZIP code only.
