The US Postal Service will no longer accept two shipping labels on one package

The US Postal Service has stopped allowing packages to carry two shipping labels. This means senders can no longer use a single package for both outbound and return shipping.

This change simplifies the shipping process for the Postal Service. It removes a small operational complexity that could lead to errors or confusion in sorting and delivery. For businesses that used this method, it means they will need to find alternative ways to handle returns or multi-leg shipments.
