On Monday people were filling the Rushmore Mall parking lot to get their papers shredded.
As part of Operation Stop Scams, the AARP offered free shredding with the help of A to Z Shredding.
They say 33 percent of reported identity theft in South Dakota is tax or employment document related.
And especially after tax season, they want to help people clean out their closets to prevent criminals from getting personal information.
Consumer Credit Counseling says be aware of who you're giving your personal information to and understand what documents to keep and what should be shredded.
Consumer Credit Counseling Education and Community Outreach Manager Terry Mills says, "Anything that you don't keep in your spending plan like credit card receipts, check receipts, and things like that you should keep. Always keep those in a very safe place in case somebody would break in and steal that information. Otherwise, shred everything else. Anything with your name or address like utility bills, cable bills, even stuff like that because criminals are looking for information."
Last year AARP shredded 7,000 pounds of paper.
On Tuesday they'll be at the Safeway in Spearfish from 11 A.M. to 1 P.M. offering free document shredding again.
