Important safety notes for Anthropic

Because these numbers are shared publicly, use them only for accounts you can afford to lose access to. For your primary Anthropic account with real data, use a private US number instead. After signup, add an email backup so you're not dependent on the shared phone number for password recovery.

Frequently asked questions

Does Anthropic block virtual numbers?

Anthropic uses standard carrier lookups. Our numbers are real US mobile numbers via licensed telecom carriers, so they typically pass. If a specific number is blocked because of heavy prior use, try another from the list.

How fast do Anthropic codes arrive?

Typically within 30 seconds. Occasionally up to 90 seconds during peak carrier delays.

Can I create multiple Anthropic accounts with virtual numbers?

Technically yes, but check Anthropic's terms of service — most platforms prohibit multiple accounts per person and can ban all associated accounts if detected.

Do I need to be in the US to use these numbers for Anthropic?

No. The numbers are US-format but receive SMS globally. You can be anywhere in the world and still get Anthropic codes on our US numbers.

Can I use these for Anthropic password recovery later?

Not recommended. Add your email as a backup recovery method inside Anthropic immediately after signup. Shared numbers can be re-used by others — you may lose access if you rely on the same shared number for recovery months later.

Is using a virtual number to sign up for Anthropic legal?

In most jurisdictions yes — you're providing a real, functional US mobile number as requested. Check Anthropic's specific terms of service for any restrictions on virtual/temporary numbers.
