Do I need a phone number to register Claude?

In most cases, an email is enough — no phone number required. Domestic mailboxes are unreliable at receiving verification mail, so a Proton or other overseas mailbox is recommended.

Which email should I use to register Claude?

A Proton free mailbox is recommended (no phone number, has a Chinese interface) — it takes about ten minutes to set up and can be used to apply for a Claude account afterward.
