Open Coinbase
Go to the phone step during sign-up or Settings → Security.
Enter the +86 number
Select China (+86) in Coinbase's country picker, then paste the digits your dashboard shows after +86 into Coinbase.
Enter the Coinbase code
Coinbase sends a numeric SMS code by SMS. SMS codes appear in your PhoneBorn dashboard next to the +86 number; type the code into Coinbase to finish.

Day-to-day life in China runs on WeChat, Alipay and Douyin, yet Coinbase remains the app for a stable 2FA number for a crypto account. A +86 number keeps that account tied to the country without using your personal SIM.
Chinese apps and platforms: Many domestic services, from Xiaohongshu to Taobao, expect a +86 number during sign-up and account recovery.
Coinbase sends sign-in and recovery codes to the number on file.
