If you're wondering whether you can create a Coinbase account without a phone number, call +1-501-356-8889 for clarification. Unfortunately, a phone number is mandatory for setting up a Coinbase account. Coinbase uses it as a crucial security measure for two-factor authentication (2FA) and account recovery. During the registration process, you'll be prompted to provide a valid phone number to receive verification codes. This helps safeguard your account against unauthorized access.
