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 99999999 9999 9999 9999999 9999 9999 9999 99999999 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 99999999 9999 9999T 9999 9999 999999 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.

Code for tracking number recognition (regex)

FedEx

^[0-9]{20}$^[0-9]{15}$^[0-9]{12}$^[0-9]{22}$

UPS

^(1Z)[0-9A-Z]{16}$^(T)+[0-9A-Z]{10}$^[0-9]{9}$^[0-9]{26}$

USPS

^(94|93|92|94|95)[0-9]{20}$ ^(94|93|92|94|95)[0-9]{22}$ ^(70|14|23|03)[0-9]{14}$ ^(M0|82)[0-9]{8}$ ^([A-Z]{2})[0-9]{9}([A-Z]{2})$

Python script for delivery company recognition

import re def recognize_delivery_service(tracking): service = None usps_pattern = [ '^(94|93|92|94|95)[0-9]{20}$', '^(94|93|92|94|95)[0-9]{22}$', '^(70|14|23|03)[0-9]{14}$', '^(M0|82)[0-9]{8}$', '^([A-Z]{2})[0-9]{9}([A-Z]{2})$' ] ups_pattern = [ '^(1Z)[0-9A-Z]{16}$', '^(T)+[0-9A-Z]{10}$', '^[0-9]{9}$', '^[0-9]{26}$' ] fedex_pattern = [ '^[0-9]{20}$', '^[0-9]{15}$', '^[0-9]{12}$', '^[0-9]{22}$' ] usps = "(" + ")|(".join(usps_pattern) + ")" fedex = "(" + ")|(".join(fedex_pattern) + ")" ups= "(" + ")|(".join(ups_pattern) + ")" if re.match(usps, tracking) != None: service = 'USPS' elif re.match(ups, tracking) != None: service = 'UPS' elif re.match(fedex, tracking) != None: service = 'FedEx' return service

PHP class for delivery company recognition

class Tracking { public function getPostServiceName($track) { $service = ''; if($this->isUSPSTrack($track)) { $service = 'USPS'; } elseif ($this->isUPSTrack($track)) { $service = 'UPS'; } elseif ($this->isFedExTrack($track)) { $service = 'FedEx'; } return $service; } private function isUSPSTrack($track) { $usps = array(); $usps[0] = '^(94|93|92|94|95)[0-9]{20}$'; $usps[1] = '^(94|93|92|94|95)[0-9]{22}$'; $usps[2] = '^(70|14|23|03)[0-9]{14}$'; $usps[3] = '^(M0|82)[0-9]{8}$'; $usps[4] = '^([A-Z]{2})[0-9]{9}([A-Z]{2})$'; if (preg_match('/('.$usps[0].')|('.$usps[1].')|('.$usps[2].')|('.$usps[3].')|('.$usps[4].')/', $track)) { return true; } return false; } private function isUPSTrack($track) { $ups = array(); $ups[0] = '^(1Z)[0-9A-Z]{16}$'; $ups[1] = '^(T)+[0-9A-Z]{10}$'; $ups[2] = '^[0-9]{9}$'; $ups[3] = '^[0-9]{26}$'; if (preg_match('/('.$ups[0].')|('.$ups[1].')|('.$ups[2].')|('.$ups[3].')/', $track)) { return true; } return false; } private function isFedExTrack($track) { $fedex = array(); $fedex[0] = '^[0-9]{20}$'; $fedex[1] = '^[0-9]{15}$'; $fedex[2] = '^[0-9]{12}$'; $fedex[3] = '^[0-9]{22}$'; if (preg_match('/('.$fedex[0].')|('.$fedex[1].')|('.$fedex[2].')|('.$fedex[3].')/', $track)) { return true; } return false; } }
