First, make sure the DVD rental kiosk you're trying to use is, in fact, a redbox (click here to find the redbox locations near you). Occasionally, a redbox will be completely full, and won't allow you to return a DVD. In this case, please return your DVD to another location. Still need help? Please call redbox Customer Service at 1.866.733.2693, 7 days a week, from 7:00 a.m. to midnight Central Time for prompt resolution of your problem.
