The CTA wants to remind riders who bought their Chicago Card Plus or Chicago Card four years ago that these cards will expire this year and free replacements are available.

About 59,800 cards are set to expire beginning in April through the end of the year. Customers can check the expiration date on their Chicago Cards online at www.chicago-card.com, at most rail stations, by calling 1-888-YOUR-CTA or visiting CTA headquarters at 567 W. Lake St. Monday through Friday.
