Hello, glad to answer your question.

There doesn't seem to be an area code for invoices in general.

There are two numbers on an invoice, one is the invoice number (usually the top right corner) and the other is the invoice code (usually the top left corner). Then, the invoice number generally has fewer digits than the invoice code, en, it also has the word No. written on it, which is also called the invoice slip number. Invoice number is the tax department to give the invoice coding smack code, in checking the authenticity of the invoice, you need to enter the invoice number, the invoice number is generally 8 digits, by year, batch preparation.

The code of electronic special invoice is 12 digits, and the coding principle: the first digit is 0, the 2nd-5th digits represent provinces, autonomous regions, municipalities directly under the central government and planned stools of single-listed cities, the 6th-7th digits represent the year, the 8th-10th digits represent the batch, and the 11th-12th digits represent the type of invoice (11 represents the electronic value-added tax general invoice).
