Where can I find the company official seal number?

The industrial and commercial bureau where the company is located. It should be noted that the official seal number has important security significance in the company, similar to the personal ID number. Therefore, in order to prevent criminals from using this information to make forged official seals, online public inquiries are usually not provided. If you need to inquire, you generally need to hold a letter of introduction or a lawyer's certificate from the relevant institution and go to the corresponding public security organ or industrial and commercial bureau to inquire. In addition, some areas may provide specialized online inquiry platforms, such as the seal inquiry platform in Sichuan, but this service may not be widely provided. Therefore, the most reliable method is to directly contact the industrial and commercial bureau or the public security organ where the company is located for consultation and inquiry.
