Hello, Yuyang Intellectual Property Agency will answer for you. There are some registered trademarks using numbers, but the most important thing is to see what category you are registering, whether there are similar trademarks, etc., so that analysis can determine whether A trademark cannot be registered. I only checked 80 for you. The amount of data is too large. You can check it yourself. If you want to register a trademark, you can ask a professional agent.
