legal subjectivity:

1. First, it is necessary to distinguish whether it is a national tax invoice or a local tax invoice, which can be distinguished from the "National Uniform Invoice Producer Seal" on the face. If the seal is printed with the words "produced by the State Taxation Bureau of _ _ province" or "produced by the State Taxation Bureau of _ _ city", enter the website of the State Taxation Bureau of the province or the city for inquiry; If the seal contains the words "produced by the local taxation bureau of _ _ province" or "produced by the local taxation bureau of _ _ city", enter the website of the local taxation bureau of the province or city for inquiry. You can search the website directly in Chinese. If you want to inquire about the sales invoices issued by our company for our customers, you can directly search in Chinese and enter the website of Dongguan State Taxation Bureau. 2. After entering the tax bureau website, the pages of different tax bureau websites will be different. However, when you want to check invoices, you usually click the words "invoice query", "invoice inspection" and "invoice comparison" to enter the query. After clicking, an interface will pop up asking for invoice information. Enter the relevant information according to the prompts, and then click "OK" and "Query" to pop up the query results, usually with invoice purchase information. If there is something wrong with the invoice, words like "Our Bureau has never sold this invoice", "No invoice found" and "No record found" will generally appear. 3. You can dial the national unified tax service hotline (area code +12366) for consultation and inquiry. 4. Confirm whether the other party has a legal invoice purchase record by providing a copy of the Invoice Purchase Record containing the invoice code in the Invoice Purchase Book.
