Is there any place to get patterns for shipping tracking numbers for all shipping companies like UPS,FedEX, DHL, AirBorne, USPS ...
Fedex: 12, 14, 15, 20, 22 digits are all valid tracking number
UPS: 1Z + 16 digits or begin with W,T,H + 10 digits
DHL: 10 digits ONLY (if u mention the express shipping, as DHL also have cargo, sea shipment etc)
usps: https://tools.usps.com/go/TrackConfirmAction!input.action
Notice that as far as i know, there is not a complete list there.
If anyone know the new tracking number format, please let me know too.
As I run a startup http://www.aftership.com which also need to detect the tracking number pattern.
