If you want to restart your Netflix account to get back to watching your favorite TV shows and movies, simply sign in to Netflix.com and click Restart Membership from any profile except a Kids profile.
If your account is inactive, you'll be asked to restart your membership once you sign in to Netflix. Your billing date will change to the date you restarted your membership on.
If your account hasn't closed yet, you can keep your active account status by clicking the Restart Membership link on your Account page. Your billing date will not change.
