Hello! Yes, there are other methods you can try if you want to change your Facebook name and you have reached the limit. Here are a few options you can consider:
1. Contact Facebook Support: You can try reaching out to Facebook's support team directly through the Help Center. Explain your situation and ask if they can assist you in changing your name despite the limit.
2. Provide Legal Documentation: If you have legally changed your name, you can upload the necessary documentation to Facebook for verification. This may include a driver's license, passport, or marriage certificate.
3. Create a New Account: If all else fails, you can consider creating a new Facebook account with the desired name. However, keep in mind that this may result in losing your current friends, photos, and other data associated with your old account.
Remember to always follow Facebook's policies and guidelines when making any changes to your account. I hope these suggestions are helpful to you! Let me know if you have any other questions.
