Photograph the label on a parcel you received, straight on, small print sharp, barcode and printed codes in frame; cut-off barcodes, blurred text and steep angles are rejected. Up to 100 per contributor, from a global base strongest in Southeast Asia, the United States and Europe, so expect regional couriers such as J&T, Ninja Van, LBC and JNE alongside USPS, Royal Mail, DHL and the global integrators. No field annotations are included. Label-reading models usually train on a few carriers' templates and fail on the long tail: regional couriers, thermal labels that smudged in transit, hand-applied stickers over the original, barcodes that warped with the box. An OCR and barcode set on labels as they arrive.
