Sometimes the tracking information does not seem to move or populate for some reason at the origin USPS post office. Sometimes packages are scanned at the next receiving USPS and then the scan updates. If your label has just been created within 1-3 business days, please be patient as we print labels as a first stage in our shipping process and then process shipments in batches one through three. If our total shipments are on the larger side, three batches and if on the smaller side, just one batch.
