My phone number shows "exceeded limits" when registering

Hello,
I am trying to register a NVIDIA account, but when I enter my phone number **+86 13518347983**, it shows the error:
“This phone number has exceeded limits, please try a different phone number or try again later.”

I confirm that I have **never used this phone number to register or verify any NVIDIA-related account before**. This is my personal mobile number, and I suspect it may be a recycled number from the carrier or a system misjudgment.

Could you please help check the status of this number and lift the restriction so that I can complete the registration?

Thank you very much for your assistance.
