Adding your mobile number to your account

To add your mobile number to your Twitter profile from the web:

1. Log in to twitter.com and click on the gear icon.
2. Select Settings from the drop-down menu.
3. Click on the Mobile tab.
4. Choose your country from the first drop-down menu.
5. Enter your mobile number. No need to include your country code or leading zero; we handle these automatically. Users located outside of the US may need to follow separate instructions, listed below.
6. Click Activate phone to begin verifying your phone.
7. You will be directed to send the word 'GO' via text message to Twitter (using the appropriate country-specific short code).
8. Text the verification code from your phone to that short code.
9. After we receive the verification code from you, your mobile device will be added to your Twitter account!

If you are located outside of the US, you may need to follow these extra steps:

• You will be asked to Choose your carrier after you've entered your mobile number.
• Select your carrier and click Activate phone to verify your phone (if you don't see your carrier listed, read this article).
• You may need to select the desired language you'd like to send and receive Tweets in.

Congratulations! You can now send and receive SMS text message updates via Twitter for SMS!

To add your phone to your Twitter account via text message to a short code:

When you use a short code with your Twitter account, you can post Tweets, receive notifications, and enroll in security features like login verification.

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.

To add your phone to your Twitter account via 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.
