To sign up for a Yahoo! account, visit the Yahoo! website. Locate the "Sign Up" link and click it. Fill the sign-up form with your name, a chosen Yahoo! username or ID, password, mobile number, date of birth and gender. Click on "Create Account" to submit the registration details.
Choose a username and password that is easy to remember to avoid getting locked out of your account. Check the availability of a username, because each account must have a unique Yahoo! ID. Additional details, such as a recovery phone number and security questions, may be requested. To check email once the account is established, visit the Yahoo! homepage, click on the "Sign in" link and log in with your credentials.
