Recently while creating a Dynamics 365 Trial, https://dynamics.microsoft.com/en-us/dynamics-365-free-trial/, we were getting the below error, during the verification step
“Sorry, we need additional information to verify your identity. Please Contact Support”
This error could be related to the same phone number being used multiple times to create the Dynamics 365 trial or could be related browser cache.
Before trying with a new phone number, we should first try creating a trial in the In-Private mode (or clear cache in the browser).
In our case, the In-Private mode worked as shown below, and we were able to create the trial.
Hope it helps..
