This article has information related to purchasing shipping labels from the Shipstation. If you purchased your shipping label through the PayPal Shipping Center, visit our PayPal Shipping Center for more information.
The USPS uses Automated PackageVerification (APV) to confirm that all shipments match the details on thelabel. If you entered incorrect package weight, package size, or destinationaddress, it could result in underpaid postage. If you haven't paid enough tocover the postage for your package, USPS will deduct the differential amount ofthe label automatically from your PayPal account. If you've overpaid, it'llrefund the excess amount automatically to your PayPal account.

- Dimensions - Report accurate dimensions when purchasing labels.Dimensional weight (volumetric weight) may apply to your packages and providingcorrect dimensions will help you avoid underpaid postage.
- Correct address - Make sure that you enter the correct address andcorrect zip code. Any discrepancies in this would result in extra charges.
- Match the label to the packaging - USPS provides a wide range ofshipping options to help you meet your mailing needs. Make sure that the labelyou're using matches the packaging.
