SiliconFlow 硅基流动 SMS Verification

Developers without a Chinese SIM can clear the SiliconFlow 硅基流动 SMS verification with a virtual number, but real-name verification is still required to use the models.

SiliconFlow (硅基流动) is a Chinese AI cloud platform operated by Beijing SiliconFlow Technology Co., Ltd. that gives developers API access to models such as DeepSeek. On the China-facing siliconflow.cn site, registration and login require a phone number and an SMS code, and under Chinese law the platform also runs real-name verification before any product can be used.

A virtual +86 number can receive the sign-up code, but according to the privacy policy individual accounts match your name and ID number against Alipay face recognition, while companies verify through a legal representative or a corporate bank transfer. This route only makes sense for people who can complete verification with their own identity but cannot reach a Chinese line right now.

Do not try to sidestep real-name verification; unverified accounts cannot top up or request invoices. Because each account can be bound to only one verified subject, teams should use corporate verification. Your balance and API keys live in the account, so secure login with a number you can keep or a linked e-mail, and never share your API keys.
