1. The name of the door head must be consistent with the business license. If the local industrial and commercial bureau finds that the name of the door is inconsistent with the contents of the business license, it will generally ask for a change. Business licenses are divided into originals and duplicates, which have the same legal effect. The original shall be placed in a prominent position in the company's domicile or business premises, and the business license shall not be forged, altered, leased, lent or transferred.

2. Legal basis: Article 20 of the Regulations on the Administration of Enterprise Name Registration

The name used in the enterprise seal, bank account, plaque and letterhead shall be the same as the registered enterprise name. The name plaque of an enterprise engaged in commerce, catering, service and other industries may be simplified appropriately, but it shall be reported to the registration authority for the record.

Second, is the use of the company name as a trademark infringing?

Trademark infringement refers to other acts in which the actor uses the same or similar trademark on the same or similar goods without the permission of the trademark owner, or interferes with or hinders the trademark owner from using its registered trademark, thus damaging the legitimate rights and interests of the trademark owner. The infringer usually bears the responsibility of stopping the infringement, and the actor who knows or should know that it is an infringement is also liable for compensation. If the circumstances are serious, they shall also bear criminal responsibility.
