A UPS tracking number, for domestic packages within the United States, will usually start with "1Z" followed by a 6 character shipper number (numbers and letters), a 2 digit service level indicator, and finally 8 digits identifying the package (the last digit being a check digit), for a total of 18 characters.
Because Codabar is self-checking, most standards do not define a check digit. [3] Some standards that use Codabar will define a check digit, but the algorithm is not universal. For purely numerical data, such as the library barcode pictured above, the Luhn algorithm is popular. [4] When all 16 symbols are possible, a simple modulo-16 checksum ...
The service became quickly popular: for UPS the number of packages tracked on the web increased from 600 a day in 1995 [9] to 3.3 million a day in 1999. [10] On-line package tracking became available for all major carrier companies, and was improved by the emergence of websites that offered consolidated tracking for different mail carriers. [11]

In a database, storing the ZIP+4 code in a 10 character field (with the hyphen) allows easy output in the address block, and storing the check digit in a 3-digit field (instead of calculating it) allows automatic checking of the validity of the ZIP+4 and delivery point fields in case one had been changed independently.
This section of the code may be omitted, but if it is present, the 5-, 9-, or 11-digit forms of the ZIP Code are also encoded in the Intelligent Mail barcode.

The next 7 digits is the Serial Number of the AWB; The last digit is the Check digit. The check digit is derived by dividing the 7 digit Serial Number by 7. The remainder determines the Check Digit. Example: Serial Number 8114074 divided by 7 is 1159153 with remainder 3. To easily calculate the remainder you can divide the 7 figures by 7, then ...
