Document Numbers

Every bill is uniquely identified by its bill ID. Bill ID is a random, system-assigned number. In some locales utilities may be required to assign and print an additional document number. For example, in Argentina a utility must obtain authorization from the national tax agency before they are allowed to print bills at a local office. Once authorized, the utility is assigned a printing authorization code valid for a period. The printing authorization code and expiration, as well as an official document number are printed on the bill at the location where the bill is issued.

The topics in this section describe how document numbers are implemented in the system.
