The trademark registration number is a unique identifier assigned by the trademark registration agency to each successfully registered trademark and is used to identify and distinguish different trademarks.

According to the principles of the trademark registration system, trademark registration numbers should be unique and there should be no identical registration numbers.

The uniqueness of a trademark registration number is an important guarantee for ensuring the recognizability and independence of a trademark in terms of legal protection and management.

However, there may be rare special cases of errors or duplicate allocations, but these should be very rare.

If there are duplicate trademark registration numbers, it is recommended to contact the local trademark registration agency or the relevant intellectual property department to verify and solve the problem.

In short, the trademark registration number should be unique and used to accurately identify and manage the trademark registration information.
