Twitter prioritizes the safety and privacy of all users, which is why it is possible for Twitter Blue users to enable SMS codes so they can safely log into their accounts.

Nevertheless, this Twitter code does not always work. If you are struggling to get SMS login verification codes on your phone, then you are not alone.

This guide has the best troubleshooting tips and solutions to address the following topics:

  1. Why is Twitter not sending verification code?

  2. Best ways to fix verification code problems on Twitter;

Why is Twitter Not Sending SMS Verification Code? 3 Possible Reasons

Twitter normally sends SMS verification codes without problems when users who have enabled two-factor authentication wish to log into their Twitter account.

However, if Twitter is not working because you are not receiving SMS codes, the problem might be caused due to any of the following reasons:

  1. Delays in SMS Delivery: One of the most common reasons why users don’t get the SMS code is due to delays in the SMS delivery. Normally, the text message takes a few seconds to arrive, but it may take longer, so it’s important to be patient;

  2. Problems with your mobile device: If the network of your device is offline or if airplane mode has been enabled, you will not get an SMS code to log into your Twitter profile. Login requests through 2FA only work if your phone is suited to receive SMS text messages;

  3. The Twitter phone number is blocked: Twitter uses a 40404 mobile number to send the login code via SMS. If this number has been accidentally blocked, it will not be possible to receive the Twitter short code on your phone.

How to Fix Twitter Not Sending Verification Code

There are several ways to fix Twitter not sending verification codes, but keep in mind that the ideal solution depends on the initial trigger of the problem.

Follow the following 6 fixes to address issues with login authentication on Twitter.

Solution #1: Check Your Mobile Network and Contact Your Mobile Carrier

Your phone will only receive SMS codes from Twitter if your mobile network is working without problems.

To check this, follow these steps:

  1. Make sure that your phone can receive SMS and phone calls from other numbers;

  2. Turn off Airplane Mode on Settings in case this feature has been accidentally enabled. Check if your Internet connection is working to ensure Airplane Mode has been turned off;

  3. Contact your mobile carrier if you are unable to receive SMS. It is also worth noting that SMS codes will not be sent if you don’t type your phone number correctly on an existing app session.

Solution #2: Unblock Twitter Phone Number

One of the possible reasons why you are unable to receive SMS codes from Twitter is that the Twitter phone number has been blocked. To unblock Twitter’s phone number, do this:

  1. Open the Settings App of your phone and go to Phone. Some Android versions have a dedicated Phone App where you can manage blocked numbers;

  2. Look for the “Blocked Numbers” option. You may need to tap the three dots icon to access this option in certain Android models;

  3. Look for a 40404 number and unblock it. Once you click “Delete,” the number will be removed from the block list, which will allow you to receive Twitter verification codes without further inconvenience.

Solution #3: Check Out Twitter Blue Credentials

From March 20, 2023, and onward two-factor authentication via SMS is only available to Twitter Blue users.

According to Twitter, unverified users who have not paid for Twitter Blue subscriptions “will be prompted to disable it before you can continue to use their accounts”

If you cannot use SMS verification codes anymore, you may need to subscribe to Twitter Blue. The subscription is $8 per month in the United States, and although you could get 2FA via other methods (such as authentication apps).

Solution #4: Turn On Twitter Push Mobile Notifications

Perhaps Twitter is not sending the SMS code because you have mobile notifications turned off. To solve this problem, try these steps:

  1. Make sure that mobile notifications are enabled on your phone’s Settings;

  2. If so, then let’s check recent login requests to see if the problem is related to the login push notification or any other reason;

  3. Log into Twitter, go to Settings, open Account, select Security, and tap “Login Requests;”

  4. Here, you will see all recent requests to log into your account from the official Twitter client (desktop and mobile versions);

  5. Tap “Request a code sent to your phone via SMS.” From now on, the code should arrive without problems. Remember that having push notifications enabled is imperative to get the SMS code.

Solution #5: Update Your Mobile Settings with a New Backup Code

When you enroll in two-factor authentication, you can generate a backup code to protect your profile in case you get a new phone or lose your old phone.

If you manage to log into your account from a laptop, computer, or another device, you may need to set an active backup code to get SMS verifications again. To do this, follow these steps:

  1. Log into your Twitter account, select “Settings,” and tap Account information;

  2. Now, select Security, and tap Backup Codes;

  3. Generate a new backup code - you will get a link request to do so. Then, make sure to share the newly generated code somewhere.

Many Twitter users get an error message if they attempt to use an inactive backup code on a new device or existing session, so restarting your code is a great way to continue using 2FA

Solution #6: Contact Twitter Support

Lastly, if nothing works and you simply can’t access your account by using 2FA via SMS, then it’s time to contact Twitter Support.

Twitter Support will help you whether the number has been registered on any other account, you have lost your device, or the message is simply not being sent by Twitter.

Go to the official Twitter Support Contact page, select “I’m having problems with account access,” and choose “I’m having problems authenticating my account.”

Explain your case to Twitter, and wait for an answer.

By following all these fixes progressively, you will be able to get rid of Twitter not sending verification code issues on the app.

Keep in mind that contacting Twitter Support is only advisable if any of the other solutions work, as the Support Team might take a while to respond.
