    This phone number has been used with a recently deleted account and is currently unavailable.

    Hi @tion,

    Thank you for your message.

    It would be helpful for us to investigate if you can tell us the country you are in.

    Currently,  TeamViewer introduces account validation to unverified users in China which corporates with validation code in the text message. When you delete your TeamViewer account we delete all data related to your account. However, the phone number associated with the deleted TeamViewer account cannot be used to validate a new account until 2 months after the deletion.

    For more information, feel free to check out this KBA  and follow up on this post for more updates.

    Best regards,

    I am reporting the same issue in China. I am a holder of a valid Chinese sim card. My Teamviewer has been updated to the new version, and two-factors authentication activated.

    When trying to connect to any other computer, a messagge for account validation through SMS pops up. After following the procedure, the SMS never arrives. This is extremely annoying, as it prevents completely from the use of the service.

    A workaround on how to fix this issue would be appreciated.



  • I deleted it and registered account again with same email. Now I got this message. What is this? Should I buy a new SIM on every my China trip?

    Hi @Shaeek,

    May I know your location? TeamViewer introduces account validation to unverified users in China which corporates with validation code in a text message when they start the first outgoing connection and start a meeting. Therefore, if you are requested to validate your account in China please check out this thread for more information.

    Hi @Shaeek,

    Thank you for your confirmation.

    Please take a look at this article for the specific steps. We recommend using Chrome, Edge, Safari or Firefox browsers on a computer to validate, and please make sure that Cookies are enabled.

    Hi @Ying_Q, thanks for your reply.

    I am pretty sure my input mobile number is true and valid.

    When I checked the link you shared, I saw there was "点击按钮开始智能验证" below input area in the screenshot, but it never showed in my page. I don't know if there is anything else I can do but it is quite urgent for me to use Teamviewer and hence I really need your help. Look forward to your reply.

    Before, Fiona_ G. The staff member can release the mobile phone number after replying to it for two months, but it has been more than two months and has not been released yet. I see that some articles are longer, four months. Please give an exact reply. Can't you release it? I can make a choice and whether to discard it。

    I'm a bit troubled.

    I'm using teamviewer for a while now and it worked fine for me. I checked everything before I left home and got on a businesstrip to China.

    Now I want to access my PCs at home and I just can't because: "please validate your account to continue"

    1. Why do I need to do this now. I'm using the same account and same Notebook as I did before to connect to the same PCs as before.
    2. TV wants a Chinese Phone number to do so. I'm German, try to reach my German PCs with my German Notebook which I used in Germany before. Why Chinese number? Makes no sense at all!
    3. Got a Chinese Phonecard send to my Quarantine Hotel. Workes fine for everything. Just not for TV: invalid number....

    So what can I do now to be able again to connect to my PCs?

    PS. I'm using the free license and try to reach my private PCs

    I also meet the issue, I have a valid Chinese phone number. But when I enter it, it shows that your phone number is invalid. Can someone help me with it?

    In this post, the topic is the same as the below one

    Now it's April 29, 2022. There is still no improvement. Everytime I try to connect any computer and keep showing something like "your +86 phone number is invalid" to me. Are you guys really able to solve this problem? Or just ignoring users in China?

    phone number ISP: China Unicom

    I'm having the same issue. Although this is not my first visit to China and until now, I had no issues using TV during past trips. This most recent trip has proved difficult and though I also have a local mobile number, TV claims it is invalid to use for validating my account. Have you heard from support staff or found any solutions to this issue?

    Hi. Any updates on this issue? It seems like months later and the "validation system" still doesn't work.

  • ceciljchen
    ceciljchen Posts: 3 Newbie

    It's crazy that users have been complaining about this issue for nearly 2 years and it still hasn't been resolved competently. I've been using teamviewer for more than a decade and it had always been a smooth experience. Wonder what has changed? Any solutions or workarounds to this issue?

    SMS cannot be sent from China , use Chinese mobile phone number for confirmation-Invalid phone number provided, how to solve?

  • blaaaaarrgh

    I had the same issue just then. You'll need to turn off your VPN and then the website will display correctly. The dialogue box where you enter the phone number will look different.

    I can only see one option to validate the teamviewer account and that is via SMS. But I cannot validate as it continuously shows this message. By the way I deleted the account several months before as I cannot add my computer after installing new windows. And it was 4-5 months before... Now I cannot receive SMS to validate the account.

    As the above problem persist, how can I activate the teamviewer account ?

    Hello Fiona,

    Thanks for your explanation. I am using a free account right now and I cannot validate this account with my phone number. I am pretty sure that the previous account (email abandoned) has been deleted for OVER two months.

    Any updates to this issue or has the policy changed somehow?

    Hi Teamviewer,

    I havnt used my team viewer account for a while, and recently when I did, I get this prompt and then an ask to validate the account via a Chinese phone number. But when I entered my phone number, i get another prompt of it is being used by another account. This is a little weird because I've never associated a Chinese phone number. Where can I check phone # association?
