NR Submission Phone Number Validations

In Name Request, since people can use both a phone number and email to retrieve their existing NRs, it would be good to validate their phone numbers as well within the submission flows.

Right now a user can continue with a phone number that is just "55" without seeing an error message, which may cause issues if they try using their phone number to retrieve their NR later on.

I think validations would need to work for international numbers as well

Was this something we were going to include at some point @Kaineatthelab

Not a P1

Start by locating the Name Request submission flows and the existing phone or email validation. Check how a short value such as "55" currently proceeds and how international numbers are represented. Done means invalid phone numbers show an error before submission while valid international numbers remain usable.
