Applicant Information
To sign up as an applicant, the system will ask you to enter some of the applicant’s personal information. The first screen will request the applicant’s first and last legal name as well as the last four digits of the SSN (or the full number, depending on the State), and the Date of birth (MM/DD/YYYY).
What does "Legal" mean?
If the applicant’s name is ‘Robert’ and that is the way the name appears in any proof or documents to be used as proof, the only way to enter the name in the application is ‘Robert’. No nicknames (E.g., Rob, Bob, Bobby, etc.) should be added, as the proof and enrollment will get rejected if any alias or nicknames are used. Agents will also be able to introduce Middle name and suffixes if needed.
The applicant’s email address is a mandatory field, and it should be entered to make sure that, if needed, customers can be contacted. Applicants can also indicate if they are interested in receiving promotional offers.

After introducing the applicant’s PII, the system will verify that the applicant does not have another enrollment created. If that is the case, the following pop up will be displayed.

To keep in mind: If the device in use does not have a front camera, or permissions to access the Quest app have not been granted, the Quest app will not be able to continue with the enrollment process.
In the following section, ST Agents will have to introduce the customer's physical address. There will be a specific section for them to introduce the applicant’s apartment, unit, etc., if applicable. The applicant’s City, State and Zip Code will be auto filled as well, based on the Zip Code entered to check availability.

No PO Boxes should be added here. Only Physical addresses can be entered in this step.
Shipping Address Information
If the applicant needs to enter a mailing address different from the main address, a shipping address can be added in this same step, as long as the address is from the same state where the applicant resides. Shipping addresses can be from a relative, friend, general delivery, or a PO Box, provided they are deliverable. To introduce the shipping address, the Use this address as mailing address dropdown should be filled with a No.
