I already created a driver profile and input a number that looked to be available, without having it confirmed. Is that okay?

No, if the number has not gone through our numbering system, that number will not be considered valid and may be assigned to another driver if they select it within the numbering protocol. If you formerly created a profile and selected a number without validation, please follow the steps to confirm your number, or use the share stories space on the request form to explain your situation.
