Investigating

We are aware of instances of the following message being returned for some Stamps.com produced USPS labels when attempting to track them via /v1/tracking or on the USPS website directly:
"Tracking information will not be displayed because this package was shipped with counterfeit postage. Please contact the merchant or seller with any questions."

Stamps is aware of the issue and working on steps towards remediation.
