The software we use for printing USPS labels unfortunately uses tracking numbers that are recycled. USPS is not clearing the data correct before reissuing the numbers and hence you see details for a previous shipment.
The tracking number will update after USPS picks up and scans your package. Please allow 24-48 hours for this to update and after that you'll be able to track the package up to your address.
Feel free to email us on firstname.lastname@example.org if you have any concerns about your package.
