“Phone number format is invalid Please ensure your phone-number has the format +country-code-xxxxxxxxxx” (For INFORMED Act Account Verification)

I’ve tried several variations and Amazon isn’t accepting anything.

+12223334444 (no dashes, current phone number format that needs changing)

+1 2223334444 (Suggested in a forum to use a space)

+1-2223334444 (single dash after US code of 1)

+1-222-3334444 (dash after US code and dash after area code)

+1-222-333-4444 (Dashes after everything)
