After submitting the application, UU errands will review the applicant's information, including checking the ID card, driver's license, vehicle driving license and other information, and will also interview and train the applicant. After approval, the applicant can become a rider running errands for UU.

Applicants need to keep their mobile phones open so that UU errands staff can contact them. In addition, applicants need to wait patiently for the results of the review, and do not submit applications repeatedly, otherwise the review cycle may be extended.
