To know whether the trademark registration is successful, you can consider the following ways:

1. Notice from the Trademark Registration Office: The Trademark Registration Office will usually send a formal notice to the trademark applicant to confirm Trademark registration successful. This notice may be in writing or sent to you via email or online system. The notice will contain important information such as the trademark registration number and registration date.

2. Trademark registration certificate: The Trademark Registration Office usually issues a trademark registration certificate as confirmation of successful registration. A trademark registration certificate is a formal document proving that your trademark has been successfully registered and has legal protection. The trademark registration certificate usually contains information such as the trademark's drawing, registration number, registration date and applicant.

3. Online query system: Trademark registration agencies in many countries and regions provide online query systems. You can use the application number or trademark name to query in the system. Through the query system, you can check the status and progress of your trademark registration application. Once a trademark is successfully registered, the system will usually display the trademark registration information.

4. Announcement and registration announcement period: In some countries or regions, after the trademark registration is successful, the Trademark Registration Office will make an announcement and release the registered trademark information to the public. The notice period is usually a period of time that allows others to raise objections. If no objections arise during the announcement period, the trademark registration will be finally confirmed.

If you have submitted a trademark registration application and want to know whether it was successful, it is recommended that you use one of the above methods to check. The specific inquiry methods and channels may vary by country and region. You can consult the local trademark registration agency or professional trademark agency for accurate guidance and support.
