(2) The words "Shenzhen Local Taxation Bureau" in the upper right corner of the invoice are cancelled and replaced by 12 national general invoice classification code, and the category code (the enterprise number of self-printed invoice is reserved) is retained, and the invoice number is unified to 8 digits. When querying invoices, you only need to enter the invoice number and type code (enterprise number is required for self-service printing invoices).

When the pattern is heated, the oval in the middle changes from light purple to pink, and the lace in the periphery changes from deep purple to colorless.

In addition, the local tax invoice of our city can also be inquired by calling the inquiry telephone number printed on the invoice or inquiring the website.
