Can I redeem winning scratch-off tickets that are over a year old? Some stores could not do it.

We are not the state lottery. You will have to contact your state lottery to determine what the last day to claim date is for any of the tickets you have.

The lottery will end a game (known as the game end date) and will apply a last date to claim, usually 1 year after the game end date. However, some states have much shorter periods to claim prizes. For example, Florida has a 3-month window between Game End dates and Last Day To Claim dates for most of their games.  

So, please check your state's lottery website.  You should be able to find a page for "Last Day to Claim" information for all games.
