Valid Thru Date: This ordinarily refers to a date on which a plastic Card is disabled and becomes unusable by the cardholder but with the cardholder retaining the ability to access the underlying account or value by obtaining a new card or via a customer service transaction. Valid Thru Date should not be confused with Expiration Date, which is a date on which a Card becomes unusable with the cardholder losing the ability to access the underlying account or value. Among other rules, Valid Thru Dates are regulated by Consumer Protection Laws and proper use requires understanding of Unclaimed Property Statutes.
