How long does it take for the background check to go through?

Sometimes they are waiting on some info from you or from an area you lived in. You can check the status of your background check through this site https://applicant.checkr.com/ or you can call Rover's customer support [Edit: Rover’s contact options have changed. Visit the Rover Help Center at https://support.rover.com/ to find the phone number, help articles, or chat with the team] and they can check too!
