    Hi @Chanchal K

    Thank you for posting your question in the Microsoft Q&A forum. 

    Please note that our forum is a public platform, and we will modify your question to hide your personal information in the description. Kindly ensure that you hide any personal or organizational information the next time you post an error or other details to protect personal data. 

    Regarding the Developer Program signup error (50001): This error commonly occurs during the phone verification step of the Microsoft 365 Developer Program registration. In many cases, it happens when the phone number has already been associated with another Developer Program account or has reached the allowed verification limit. One possible workaround is to remove the existing Developer Program profile associated with that phone number or attempt the signup process using a completely different phone number.  

    You may refer to the official Microsoft 365 Developer Program FAQ for additional details on verification requirements. 

    If using a new phone number still results in the same error, the appropriate next step would be to contact Microsoft Developer Support. Support requests related to the Developer Program are typically handled through the Services Hub. Please note that access to the Services Hub depends on your organization’s support agreement and may require a paid support plan. You can review the requirements and sign-in conditions in the Services Hub sign-in FAQs before submitting a request. 

    As I am only forum moderator, I do not have access to internal Microsoft system to check this for you. All of the published threads related to this issue only pointed for contacting support.  

    I hope this information helps clarify the situation.
