Microsoft 365 Developer Signup Not Sending Code

Question

I'm trying to sign up for to the 365 developer program, but when I get the the step it's supposed to text me a code, nothing happens. Looking at the browser console while it's happening it looks like an issue with the captcha. I've included a screenshot of the console below.

I think the site’s security rules are blocking recaptcha from even starting, so the sms step never runs. open it in a private window → force‑reload → try once on mobile data… still no code then clear your browser cache and try again.

Hi @450Percent

Thank you for reaching out and for sharing the details of your issue. 

First, I’d like to clarify that this is a user‑to‑user support forum. Moderators participating here do not have access to backend systems, nor can we directly intervene in Microsoft product functionality. Our role is limited to providing technical guidance and sharing best‑practice recommendations based on reported issues, requests, and scenarios.      

Based on your description, the browser’s developer tools show repeated errors related to reCAPTCHA and Content Security Policy (CSP). This indicates that reCAPTCHA network requests are being blocked. As far as I know, this issue may be related to ad‑blocking or privacy extensions, strict browser security settings, VPN usage, or enterprise network controls that restrict access to third‑party or Google domains.

Because reCAPTCHA fails to load or complete successfully, Microsoft’s sign‑up flow never advances to the SMS verification step. As a result, no verification code is sent, even though no visible error appears in the user interface. 

To troubleshoot this issue, you could try reproducing the sign‑up process in an InPrivate or Incognito window with all browser extensions disabled. Also ensure that you are not connected to a VPN and, if possible, use a non‑corporate network or a personal device. Allowing access to recaptcha.net or switching to a clean browser profile often resolves the problem.

The verification SMS not being sent during Microsoft 365 Developer Program signup is consistent with Microsoft temporarily blocking verification codes when unusual activity is detected, when there are many repeated requests, or when there are regional/service issues with SMS delivery.

To move forward, use these supported options:

1. Avoid repeated code requests
   • Do not keep retrying the same SMS step; excessive or repetitive requests can cause or extend a block on sending verification codes.
2. Try another verification method
   • If available on the signup page, switch from SMS to an alternate email address already associated with the account and complete verification that way.
3. Try another network and browser session
   • Use a different network (for example, switch between Wi‑Fi and mobile data) and start a fresh, private/incognito browser session before retrying signup. This helps if the block or failure is tied to the current network/session.
4. Wait for the block to clear
   • If the behavior persists, wait at least 24 hours without additional attempts. Some blocks clear automatically; if there is still no change, wait up to a week before trying again.
5. Use the sign‑in helper and support
   • Run the sign‑in helper to identify sign‑in/verification issues and see available support options: use the Sign-in helper link provided in the documentation.
   • If still blocked, go to Contact Microsoft Support, describe that verification codes are not being sent during Microsoft 365 Developer signup, and then choose Get Help → Contact Support to reach a support option.

Note that Microsoft support agents cannot send verification codes or change account details; they can only guide through supported recovery and troubleshooting paths.
