The Post Tracking Number Generator generates 13-character identifiers to items for tracking them during shipping. An identifier consists of a two letter service indicator code, an eight digit number, a check-digit, and a two-letter ISO country code.
The dialog box of the Post Tracking Number Generator contains some of the Basic Settings and custom settings. You can customize the generator by changing the basic and custom settings.
Separator
