How to Add a Phone Number on Twitter on a PC or Mac

Go to https://www.twitter.com in a web browser. You can access X from any modern web browser, such as Chrome or Safari. If you’re not signed in to X, enter your account information and click Log In.

Click the smaller version of your profile photo. It’s in a circle at the top-right corner of X.

Select Settings and privacy.

Click Mobile. It’s in the left sidebar.

Enter your phone number. Your country code should be filled in automatically. If you’ve added a phone number in the past, click Edit to update it.

Click Continue. X will send a text message containing a verification code to the number you entered.

Enter the verification code from the text message. You’ll type it in the blank labeled “Verification code.”

Click Activate Phone. Once the activation is complete, you’ll see a message that says “Your phone is activated!”
