If you're a Claude user, you might soon be asked for your phone number. Anthropic is rolling out a mandatory identity verification process for some users of its AI assistant, and here's what it means for you.
The main goal is to strengthen security and ensure users are following Anthropic's safety policies.
By linking accounts to a verified phone number, the company can more effectively track and stop users who break the rules, such as those creating harmful content or spam accounts.
Why Verification is Being Implemented
Anthropic says this is a key step in keeping its AI environment safe and responsible. The identity check acts as a deterrent, making it harder for malicious users to operate anonymously.
This move is part of a broader trend in the tech industry. As AI models become more powerful, companies like OpenAI and Google are also adding stricter controls. OpenAI, for instance, uses similar verification methods for its API access, while Google's AI tools are deeply integrated with verified user accounts.
These measures are a direct response to the growing risks that come with advanced AI.
The User Experience and Process
If you're selected for verification, the process is simple. When you try to use Claude, a prompt will appear asking you to confirm your identity by entering a valid phone number.
A one-time code is then sent to your phone via SMS. You'll enter this code back into the Claude interface to complete the process and get back to your account. Anthropic says this should be a one-time check for affected users.
Impact on Privacy and Access
Adding a phone number requirement naturally raises questions about privacy. Anthropic's support documents state that phone numbers are used only for identity verification and not for marketing.
While this adds an extra step for some, it's a trade-off Anthropic is willing to make for platform safety. It remains unclear, however, what specific activity triggers the verification prompt, leaving many users to wonder if and when they'll be asked to verify.
