Signature type and requirements for signature content

When creating a signature, the signature type must be selected. The specific signature content that can be applied for for each signature type must comply with the corresponding requirements:

Signature type	Signature content	Requirements and application instructions
Company (Recommended for priority use)	Full name of the company	It is exactly the same as the name on the business license of the enterprise.
Company (Recommended for priority use)	Company abbreviation	The abbreviation must be continuously and fully included in the full name of the business license, and it must not be confused or have the same name as other enterprises. It is recommended to include regional enterprise attributes. For example, the recommended abbreviation for "Beijing ABC Technology Co., LTD." is "Beijing ABC Technology", and it is not recommended to use "ABC Technology".
Government agencies, public institutions and other organizations (Recommended for priority use)	Institution Name	It is exactly the same as the name on the organization/institution's license.
	Abbreviation of the institution	The abbreviation must be continuously and fully included in the full name on the license, and it must not be confused or have the same name as other organizations/institutions. It is recommended that it contain regional attributes.
Trademark	Trademark name	The trademark must have been registered on the China Trademark Network. ⚠ Note When a trademark is unique, the submitted signature must be exactly the same as the registered trademark name, including both uppercase and lowercase. When a trademark corresponds to multiple registered enterprises and lacks uniqueness across the entire network, the operator may require the addition of enterprise information in the signature to distinguish it. For instance, both Company A and Company B have registered the trademark "abc". When Company A applies for A trademark signature, the signature content that may be approved by the operator side could be "abc" or "abc of Company A". The actual review result shall prevail.

⚠ Note

The supported signature types have been updated. It is recommended to give priority to using "Company" and "Government/Government agencies, Public institutions/Other organizations", which can increase the success rate of real-name registration by operators.
The signature content must meet the requirements of being true, clear and uniquely identifying the affiliated enterprise/organization/institution. It cannot be confused with other enterprises or businesses and does not support neutral signatures.
