Identify shippers and valid tracking numbers from package barcodes

Project Description

Identify shippers and valid tracking numbers from package barcodes.

A package barcode string is tested against known shipper barcode types, matching the format and calculating checksum validity to identify the type provided. The module supports these barcode formats:

  • DHL
  • FedEx Express
  • FedEx Ground “96”
  • OnTrac
  • UPS
  • USPS IMpb
  • USPS UPU S10
  • USPS 20

Note: For some shippers the package barcode is the same as the tracking number, while for others the tracking number is a subset of the barcode. Inputting a tracking number instead of a barcode will work in some cases but not others.


Begin by importing the Drogher module:

>>> import drogher

Now, call the barcode function with a package barcode string:

>>> package = drogher.barcode('1Z999AA10123456784')

That returns a Package subclass containing some useful information:

>>> package.barcode
>>> package.shipper
>>> package.tracking_number

We can also ensure the package is valid, which tells us the barcode matched an expected format and the calculated checksum matches the check digit:

>>> package.is_valid

If a barcode cannot be matched with a shipper, the class does not validate and the shipper is None:

>>> package = drogher.barcode('123456')
>>> package.is_valid
>>> package.shipper

For some shippers, the barcode is not the same as the tracking number:

>>> package = drogher.barcode('420221539101026837331000039521')
>>> package.barcode
>>> package.tracking_number
>>> package.shipper
