1. Identify the authenticity of the invoice

1. Identify it from the paper.

all local tax invoices are printed on the national uniform invoice special paper, which is white in paper, and has a number of clear diamonds in the background. The diamonds contain a lantern with a watermark pattern of two capital English letters "SW" from left to right, which can be recognized by naked eyes. Fake invoices generally have no watermark, or ink is used to print watermark patterns on ordinary white paper. As long as you carefully observe, you will see the traces of ink printing.

2. Distinguish from ink.

the oval invoice producer seal, invoice classification code and invoice number of the real invoice ticket header are printed with the national unified anti-counterfeiting special ink, and the color is big red, which will emit orange light under the irradiation of purple fluorescent lamp (that is, ordinary money detector). The producer seal and number of fake invoices generally don't glow, and they look darker.

3, from the intuitive number to identify.

There are two groups of real invoice numbers. The first group is the 12-digit invoice classification code, which represents the administrative region, industry, invoice type and denomination. The second group is the 8-digit invoice sequence code.

4. Distinguish from the quality of the invoice producer seal.

the full name of the invoice producer seal is "National Uniform Invoice Producer Seal", which is produced by the Local Taxation Bureau of xx Province. The quality of the invoice producer seal for real invoices is good, and the invoice producer seal for fake invoices is rough, and some words look vague.

5. Distinguish from the printing batch number.

the invoice face is printed with the batch number of the document approved by the tax authorities to print the wholesale ticket, which is only available to the tax officer in charge of printing the invoice.
