This site is not sponsored by Kroger. There is no one here that can help you get your W2. It is a bad idea to post your name and email address on any website.
Maybe this will help you:
All you need is your SS# and your Employee ID and birthdate. Initials followed by 5 numbers. You would have used it to log into greatpeople.me to see your schedule or to see your paystub online. You can try to call the store Hiring manager and get them to look it up for you. You should have filled out a change of address form with the post office to make sure your mail follows you.
