Theoretically, the trademark registration number should be unique and the same situation should not exist.

The trademark registration number is a unique identifier assigned by the trademark registration agency to each successfully registered trademark. It is used to identify and distinguish different trademark registration cases, as well as for search and citation in trademark databases.

Trademark registration numbers usually consist of a series of letters, numbers or symbols, and the specific format and structure vary by country or region. Different trademark registration authorities may use different coding systems and rules to generate registration numbers.

Since the uniqueness of a trademark registration number is crucial to trademark management and maintenance, trademark registration agencies usually ensure that each trademark registration case is assigned a unique registration number. Therefore, the same trademark registration number should not exist in the registration database of the same trademark registration agency.

It should be noted that there may be duplicate trademark registration numbers between trademark registration agencies in different countries or regions. This is because trademark registration authorities in different countries or regions assign registration numbers independently, and their coding systems and rules may be different.

In short, the uniqueness of a trademark registration number is an important guarantee to ensure that trademark registration cases can be accurately identified and managed.
