Duplicating and reprinting a label are two very helpful but very different ways to regenerate a specific shipping label.
Duplicating a label
When you duplicate a label, you are essentially requesting a new label to be created and purchased for the same customer. This is particularly helpful if you need to send a second package out to the same customer, or if you made a mistake on the first label. Therefore, a brand new label PDF is generated and you will need to repurchase.
Without any manual manipulation, the information will be identical except for a new, unique tracking number.
Reprinting a label
When you just need to reprint the same label, click the "Reprint" button from the SHIPMENT HISTORY. You are not charged again as you are just reprinting an identical copy of the same label. Some common reasons for reprints can be related to an unsuccessful first print (due to printer settings being incorrect, ink running out, etc.) or in situations such as losing the label and needing a new copy.
What if a label is reprinted and used by mistake?
If this happens once, USPS can use their decretion to let it go, or deduct it from your postage account. Learn more about APV.
What if a label is reprinted and used multiple times?
USPS will escalate it to the district manager, who will then escalate with Stamps. Stamps will then bill the customer.
