Carrier is not detected for some UPS tracking numbers

[shkrt]

There are UPS tracking numbers that look like this K1506235620.

Expected behaviour:

TrackingNumber.new('K1506235620').carrier
=> :ups

Actual behaviour:

TrackingNumber.new('K1506235620').carrier
=> :unknown

version used: 1.0.5

I don't have any record of UPS numbers besides the ones starting with 1Z. You're sure this is a tracking number and not some other number on the label?

I got that number from one of my customers, and package is actually trackable using it, as seen on the attached image:

(I intentionally painted out some info for the sake of privacy). But I also don't see that kind of numbers anywhere in the documentation.

Also, this code gives us a clue that there is also UPS tracking numbers starting with H

It appears the code comes from a UPS handwritten labels, also called a UPS Worldwide Services Waybill. I've seen several posts where it can start with A, H, J, K and T.

  UPS:
  K2479825491         (UPS ground)
  J4603636537         (UPS next day express)
  1Z87585E4391018698  (regular)
  

Another shipping website specializing in detecting tracking numbers identified 'K1506235620' (the original posters) as 1 of 4 carriers: UPS, Delnext, GLS Italy or Total Express.

When testing, it shows the same list of 4 possible carriers for anything [A-Z]1506235620.

We need to have UPS documentation reference of their format.
