Why do some official seals have numbers and some don’t?

The ones with numbers use a new type of anti-counterfeiting seal (metal seal with built-in electronic chip). The ones without numbers are old-fashioned seals (red glue seals).

The company's official seal is the company's seal for handling internal and external affairs. The company's official letters, documents, and reports to the outside world use the official seal. Documents stamped with the official seal have legal effect. The official seal is controlled by the company's legal representative. If the legal representative uses the legal representative's seal together with the official seal, it represents the company's actions.

The electronic signature system is composed of a digital certificate authentication system (public security PKI/CA system), an electronic seal management system, an electronic signature authentication system and client electronic signature software. The digital certificate authentication system directly adopts the PKI/CA system that has been built by the public security system.
