USPS
Buy USPS labels at ShipGenius rates with no USPS account needed. You can also link your own USPS business account by signing in with USPS.
Ship USPS without an account
You can rate and buy USPS labels without connecting a USPS account. Those labels use ShipGenius's own USPS account and rates.
Link your own USPS account
To use your own USPS business account, go to Settings, Carrier accounts and choose USPS. Connect USPS Account sends you to USPS to sign in or create an account, then back to ShipGenius. Finish the setup with your Master Mailer ID, EPS Account Number and CRID, and tick the NSA box if you use your own USPS NSA account.
If the USPS authorization expires, the account shows Authorization expired. Open the account to reconnect it.
Scan at counter
When you buy a USPS label, you can choose Scan at counter. You get a code to show at a USPS counter and they print the label for you, so there's nothing to print.
