1, self-employed individuals need to carry documents or letters issued by relevant departments to go through the examination and approval procedures at the public security administrative department of the public security organ at or above the county level where the unit is located. After being examined by the public security organ, they will issue a notice of seal engraving or a letter of introduction, proof, etc., and engrave the official seal at the engraving factory or engraving shop designated by the public security organ. Generally, it takes 3 to 4 days to bring the receipt to the engraving shop to collect it.

2, individual industrial and commercial households with industrial and commercial business license to pay this to the regular seal shop, seal shop is responsible for the public security bureau for the record. Take a paid copy of the industrial and commercial business license, a legal person ID card and two photos one inch smaller, and go to the designated national and local tax bureaus (if you are not clear, you can ask the industrial and commercial bureau or call 12366 to ask) to apply for the national and local tax certificates. Only when you have a good national tax certificate can you apply for an invoice (100-digit handwritten invoice and 1000-digit computer invoice). You don't need a special accountant, but whether you need to make accounts depends on the requirements of the tax bureau. Because the Ministry of Public Security has not made uniform regulations on the procedures for engraving seals, the regulations on the procedures for engraving seals vary from place to place. According to the different types of engraved seals, the procedures are different.

Legal basis: Article 8 of the Measures for the Administration of Public Security of Seals.

If there is no superior competent department, it shall apply to the local public security organ at or above the county level for quasi-engraving procedures with the business license, registration certificate issued by the registration administration department or the certificate issued by the local public security police station.
