Q. Do the MetroCards used for New York City subways expire?
Yes they do.
Here’s the pertinent info from the Metropolitan Transportation Authority (MTA):
“Every MetroCard has an expiration date. The date is located at the upper left corner on the back of the card. The expiration date is usually about one year from the date of purchase. If your Pay-Per-Ride MetroCard expires, you have two years from the expiration date to transfer any remaining money to a new card.”
“Within the first year after expiration, bring your expired card to any subway station and ask the agent to make the transfer. After that time, the expired MetroCard must be sent to MetroCard customer claims. Ask the station agent for a postage-paid Business Reply Envelope.
If your Unlimited Ride MetroCard expires, you should mail it to MTA Customer Service and request a replacement card. Pre-addressed postage paid envelopes are available at station booths.
