+86 Phone number "exceeded limits" error - Need manual verification

Hello NVIDIA Team,

I am trying to verify my phone number on build.nvidia.com, but I keep getting the error: “This phone number has exceeded limits, please try a different phone number or try again later.”

This is my first time registering, and I have not received any SMS code.

Could you please manually verify my account or whitelist my number?

Thank you for your help.
