USPS has announced stricter new policies in their effort to fight against the use of fraudulent or counterfeit labels.
You must ensure all labels are used within 30 days of purchase and never intentionally or accidentally use a label that has been refunded!
The following labels are now invalid and should be discarded:
USPS labels for which you have received a refund
Labels that you have not used within 30 days of purchase
What happens if I use an invalid label?
The packages will be confiscated and discarded by USPS, no claims against these packages will be accepted.
