How to add your phone number to your account

Adding a phone number to your account is a great step toward a better Twitter experience. If you’re thinking about adding your number, here are a few benefits:

• Keeping your account secure. With a phone number on your account, you’ll be able to enroll in security features like login verification.
• Faster account recovery. If you ever lose access to your account, having a phone number attached can make it easier for you to get back in to Twitter.
• Use Twitter via SMS text message. With a phone number on file, you’ll be able to text Tweets and receive Twitter updates via SMS texts, as long as your phone uses a supported carrier.
• Connect with friends and contacts. With a phone number on your account, you can easily connect with people you know. Read more about allowing others to find you by your phone number.

Add your phone number via SMS text message to a short code

1. Send a text to your Twitter code with the word START.
2. We'll reply and ask you to text YES to the Twitter short code.
3. Text your username to the same number. Do not use the @ symbol or quotation marks. Send your username ONLY, for example: larrybird
4. Next, text your password. This is case sensitive, so be sure you are sending your password correctly.
5. You're ready to go! Now you can post Tweets, receive notifications about your account, and enroll in security features like login verification.

Add your phone number via SMS text message to a long code

If you have to use a long code, note that it is one-way only. You will not be able to receive Tweets or other Twitter notifications to your phone through this channel, and you may be charged international message rates when using these codes. For these reasons, we do not recommend features such as login verification for long code users, as the experience may be less than optimal.

1. Begin by sending two separate text messages to the long code with the word STOP.
   
2. Wait two to three minutes before proceeding.
3. Send a text message to the long code with the word START.
4. Wait two to three minutes before proceeding.
5. Text YES to the Twitter long code.
6. Wait two to three minutes before proceeding.
7. Text your username to the same number. Do not use the @ symbol or quotation marks. Send your username ONLY, for example: larrybird
8. Wait two to three minutes before proceeding.
9. Text your password. This is case sensitive, so be sure you are sending your password correctly.
10. You’re ready to go!

To test if you have correctly added your phone, send a test Tweet to your long code number (just like sending a normal text message). Then, log in to www.twitter.com via the web to make sure your Tweet shows up on your Twitter profile. If it does, you have correctly added your phone. Once again, you will not be able to receive any texts back from a long code.

Adding your phone number to multiple accounts

You can have the same phone number associated with up to 10 Twitter accounts. It’s important to note that only the account most recently linked to this phone number can receive SMS notifications (for account activity like Direct Messages, new followers, Retweets, etc.) or perform SMS commands (such as sending (D [username] + message) for DM or RETWEET [username] for Retweets). You can adjust these notifications in your Text notifications settings. Find instructions for adjusting your SMS notification settings.

You will not be able to edit text notifications settings for any other accounts you have previously associated with your phone number. If you attempt to edit your settings on an account that isn’t your primary account, you’ll receive a message letting you know that the account cannot get these notifications because it shares a phone number with another account.
