Twitter unsupported Phone Number

Twitter asks for your mobile number in two significant cases if it detects any unusual log in from an IP address, device or observes any spam or automated activity from our account, which violates twitter’s Rules and Policies

As for the “unsupported phone number,” error means you are using the mobile or landline operator, which doesn’t allow Twitter to send you a verification code via SMS. In this case, you need to contact them and describe the issue in detail.

Why did I get this message?

Twitter now only accepts actual mobile phone numbers issued by mobile service providers. It doesn’t matter how you sign up, desktop, or any other device. Twitter will request a mobile number. One exception is if you don’t use a VPN and use newer Gmail to sign up, which has your phone number. Google most likely shares the phone number with Twitter or has it ready as soon as they might request in the future. 

Also, before requesting login, Twitter will require a google Captcha, designed to run your IP and check through google “secure” servers to see if your IP is blocklisted or using VPN. 

In this case, Google will pass Twitter either pass or phone request protocol.

Reasons for “Unsupported Phone Number” message display 

Twitter does not accept VOIP phone numbers for registration because they are VoIP (Voice over Internet Protocol) numbers, which the FCC classifies as “wireline,” a combination of wireless and landline.

 As they are classified as wireline Twitter will display an “unsupported phone number” message every time you try to verify your account with a republic wireless phone number. This message is displayed for Venmo and Twitter.

 Sometimes Twitter takes this action when they think you are spamming or acting like a bot, any other activity that violates Twitter community guidelines. It’s like the second stage of verification to make sure you’re a human. So Twitter sends you a text on your phone number, a Google Voice number (similar VOIP) you may need to enable text forwarding.

Clear your device cache (or try another browser) and see if it resolves the issue. Ensure you are not using any proxy or VPN because Twitter verifies login attempts from a different country IP for security purposes.

If your account is suspended, this pretty much means that you are banned from Twitter. A suspension, however, can be temporary and can be appealed and is usually a restriction from accessing accounts suspected of sharing fake news, spam, or harassment. To get your Twitter account back, you have to verify yourself again by texting a verification code on your phone.

Twitter will automatically log your account off all devices, and it is usually expected. Suppose Twitter notices suspicious behavior around your account, like repeated logins with an incorrect password or higher-than-normal account activity. In that case, the account will be logged out from all devices.

Using a number that no longer exists or is already registered with other accounts. Twitter will automatically display “unsupported phone number” if it finds any phone numbers being used.

Solutions for “Unsupported phone number” message

Luckily, there are ways to log in to your Twitter account without needing an active phone number(even with a wireless republic phone number). Yes, they’re all legitimate ways to get your account back and give you access again. These methods include:

  • Reset Your Password Using Email 
  • Fill out Twitter’s Account Restoration Form (it takes some time, but it’s worth it)
  • Contact Twitter Support Directly
  • Using a VoIP 
  • Use a Supported Phone number

Reset Your Account Password using Your Email

This is the first and recommended option when trying to gain access to your locked Twitter account. Find the “reset password” button on the login page and click on it. If you don’t have a phone number, input your recovery email (make sure it was the same one you used while creating your account). Once completed, Twitter will send you a verification email with an option of changing your password that you can use to unlock your account. Once you’re back in your account, you can change this password to something you like and try to remember it.

Fill Out Twitter’s Account Restoration Form (Contact Twitter Directly)

You’ll have to fill an Account Restoration Form. It is available to anyone trying to gain complete access to a locked Twitter account or you have accidentally signed out of your Twitter account.

You can request account restoration through the Twitter support section. In the form, you’ll be asked a few security questions to ascertain your identity as the account’s original owner, including your initial login details. They might ask backup security questions that you filled when creating an account.

This takes some time, as the form itself is very extensive. The response time takes a while because human operators review it individually and conclude with the decision.

If all these methods fail, don’t be afraid to contact Twitter directly. Twitter Support is open to everyone. It has a set of questions that will guide you to reset your account and thus regain access to your locked Twitter account.

 It is a similar process as filling up the account restoration form. Still, it might take a little longer with all the processes.

Fortunately, you are not alone. Twitter locked out suspicious accounts all the time temporarily and permanently too(very rare). A person can be locked out of their account for various reasons, from suspected spamming and posting offensive content, posting vulgar content, abusive or harassing someone, to something as simple as trying to create a Twitter account before you turned 13. It may sound like a joke, but it is actually against Twitter Rules and Privacy. Still, kids have a way around everything.

Use a VoIP 

VoIP, Voice over Internet Protocol, also known as IP telephony, allows people to make localized landline calls over the internet. While it might sound complicated, it is not. You might be using one right now: TextNow, Google Voice, and Skype are some of the most popular VoIP services available online. VoIP’s are usually free to use, but the premium services are more suitable and offer more services, text messaging, like a usable phone number, etc.

But there is a catch; Twitter, including Skype, doesn’t recognize most VoIP. Due to the standard evolving tactics of hackers and spammers. Twitter does the same and bans most VoIP’s because of their poor security.

Google Voice and TextNow, however, are still recognized by Twitter, with a Google Voice and TextNow usually being recognized during signup and login verification. 

That is because Google allows SMS to be sent to these company-generated mobile numbers because of security protocols. Not to mention that it’s Google is one of the most trusted companies around the globe.

If Twitter locked you or did it by yourself, try registering for a Google Voice number or other services and use that to receive the Twitter verification code. It usually works, but some phone numbers that Google Voice generates aren’t recognized by Twitter (people complain about Twitter saying that it’s an unsupported phone number), so you might have to try multiple times. If it does work, however, Google Voice will receive the verification SMS that Twitter sends, and you’ll be able to gain access to your account again.

A similar process can be done through TextNow. Still, it is recommended only if you already have their number, as registering to TextNow is lengthy. Still, the verification process is more smooth than Google Voice.

Using a Supported Phone number

When creating your Twitter account, make sure to use a supported phone number, unlike Republic Wireless supports, preventing an “unsupported phone number” message. You can use your family member’s phone number or someone living close to you just for verification purposes or buy a new phone number to avoid any problem.
