Use

In China, the official document number is used in conjunction with the official lot number to form a unique identification code for each prenumbered form.

Structure

The official document number contains eight digits and the documents are numbered consecutively. For example:

00011544
00011545

This eight-digit number is pre-printed in the upper right-hand corner of the special invoice.
