Troubleshooting UPS Error: Shipper Number Cannot Be Used

Updated

The UPS error "The Shippers shipper number cannot be used for the shipment" indicates a failure in the authentication process between ShipHero and UPS. This error typically prevents label generation until the account configuration is corrected at the carrier level.

Before troubleshooting, ensure you have your UPS.com login credentials and your most recent billing statement handy to verify account details.

Potential Causes and Resolutions

Cause Required Action
Address Mismatch Confirm that the From Address in ShipHero matches the address registered to your UPS account exactly. Differences in zip codes or suite numbers can trigger this error.
Unlinked Account Number Verify that your Shipper Number is properly connected to your [UPS.com](http://UPS.com) profile. This is often required for third-party shipping software to access your rates.
Account Suspension Log in to your UPS account (UPS Billing Center) to check for alerts or contact your UPS Representative to verify that your account is in good standing and not suspended for billing issues.
