The USPS uses an Automated Package Verification system (APV) to verify that all shipments match the details on the label, including:
If the weight, dimensions, and packaging details on the label do not match your package, or the selected mail class is not valid for the package, the USPS will automatically either charge or refund the difference of the correct rate to the account used to create the label.
Without APV, improperly-applied specifications would result in a shipment being returned, or in some cases, delivery charges for the recipient. With APV, the USPS will instead deliver the package but will then issue cost adjustments.
Adjustments Apply to All Carriers
While the Automated Package Verification system is only used for USPS labels, UPS and DHL Express labels created in the PayPal Shipping Center are also subject to post-billing adjustments.
Adjustments for undercharged shipments created in the PayPal Shipping Center will be collected with your next label purchase after the adjustment is charged. Adjustments for overcharged shipments will be refunded to your PayPal Shipping Center account as an Account Credit.
You will receive an email from the PayPal Shipping Center alerting you of USPS adjustments.
Manual Rate Adjustments at the Post Office
On rare occasions, if your shipment does not go through the APV system, any adjustments will be charged by the USPS to the recipient when they collect the shipment from their local post office.
You can view adjustments of your USPS shipments by date in CSV files from PayPal Shipping Center.

You can pay an adjustment balance through the PayPal Shipping Center in one of two ways.
Pay with your next label purchase: When you purchase your next label, the adjustment cost(s) will be automatically added to the postage costs.
Automatic charge from the PayPal Shipping Center: The PayPal Shipping Center will automatically charge your account payment method for the balance amount at the end of each business day after the nightly adjustments process.
For example, if you owe $1.00 for a USPS post-billing adjustment, the PayPal Shipping Center will charge your credit card $1.00 to return your balance owed to $0.00.
You will receive an email notifying you of the charge.
If you wish to dispute an Automated Package Verification (APV) adjustment, you will need to email USPS directly. They have an email address specifically for this purpose: VerifyPostageHelp@usps.gov
