Prepare a Free Proton Overseas Mailbox
Before registering for Claude, get an email address that can receive international mail. We recommend registering a free Proton overseas mailbox (no phone number).
Visit the Claude Website
Open your browser and go to https://claude.ai, then click Sign up to begin.
💡 Restricted local network, or a region-not-supported message? If you hit a region block locally (such as Not available in your country) or don't have a clean overseas network, see the cloud alternative: Register a Claude account with Meta Muse, completing the sign-up directly in a remote cloud browser.
Complete Email Verification
Enter your email address, create a password, then click the verification link in your inbox (check the spam folder if it isn't there).
Keep your network IP stable and avoid switching frequently to reduce the risk of account suspension.
Pros and Cons
Advantages of this registration approach
- No phone number: the Proton mailbox needs no phone verification at any point, so the barrier is low
- Short flow: prepare an email → visit claude.ai → verify your email, done in 5–15 minutes
- One account, many entries: a single Claude account works across the web app, the mobile app, and Claude Code
Limitations / things to note
- Depends on a clean, stable network: frequently switching IPs easily triggers Claude's risk controls
- Domestic mailboxes often miss the verification email: use Proton or another overseas mailbox
- Finer verification details and anti-suspension tips follow the official flow as it changes
FAQ
Q: Do I need a phone number to register Claude? A: In most cases an email is enough — no phone number required. Domestic mailboxes receive mail unreliably, so a Proton or other overseas mailbox is recommended.
Q: What should I do if my Claude account gets banned? A: Claude's risk control is stricter than ChatGPT's. Common causes include frequently switching IPs, using flagged payment channels, and violating the usage policy. Use a clean, stable network environment.
