What status updates look like
USPS statuses include acceptance, in transit to next facility, out for delivery, and delivered / available for pickup. International pieces may show customs-related delays.
Tips for accurate results
- Letter formats ending in DE can be DHL Parcel Germany — check the carrier we detect.
- ‘Arrived at USPS facility’ is not final delivery.
- International inbound can pause during customs without new public scans.
