The code for recognizing delivery company by tracking number

In this post I'm going to offer you a solution that recognizes a delivery company by tracking number.

All companies use their own tracking number format, so I have created special regular expressions for all of them. I read about formats in the official documentation of delivery companies. This solution works for the following services:

• UPS
• USPS
• FedEX
  

Formats of tracking numbers

FedEX

The most common tracking number format is 12 digits or 15 digits.
Some other less common formats may also exist, such as 20 digits and 22 digits.

FedEX tracking number examples

9999 9999 9999
9999 9999 9999 999
9999 9999 9999 9999 9999
9999 9999 9999 9999 9999 99

UPS

The most common tracking number format is a combination of 18 alphabetic and numeric characters, usually starting with "1Z". Some other less common formats may also exist.

UPS tracking number examples

1Z 9999 9999 9999 9999
9999 9999 9999
T 9999 9999 99
9999 99999

USPS

The most common tracking number format is 20 digits or a combination of 13 alphabetic and numeric characters, usually starting with 2 alphabets, following by 9 digits, and ending with "US". Some other less common formats may also exist, such as 10 digits.
