I'm from Nanning, and I just got a business license. Do I need to go to the public security bureau for filing when engraving the official seal? Or go directly to the designated place of the public security bureau? Bring the original and photocopy of the business license, the original and photocopy of the legal representative's ID card and the original and photocopy of the agent's ID card to the public security brigade of the county-level public security bureau where your company is located. After completing the simple formalities such as filling out the form there, take the notice issued by them to the qualified engraving shop designated by them to engrave the seal. You can't find the official seal of the engraving shop yourself. The company name on the official seal must be exactly the same as the name on the industrial and commercial business license, otherwise the official seal is invalid.
