they can use the number just the below the expiration date on the top of the card, i think. if you ever contest a ticket that you got in the subway, you give that number to the MTA and they can run a history on it.

ps, how did you demagnetize your card?

new bag, and I didn't notice that the back pocket has a pretty serious magnet closure. That's what I get for buying a cheap bag...

and, thank you! That gives me hope.

It can also happen if you keep your card in the same pouch as your magnetized work ID.

An attendant will give you a pamphlet to return the demagnetized metrocard in. I didn't have a receipt. You just need to note the machine where you remember buying it and at what station and the approximate balance.

Be warned, my card had about $70+ on it and the MTA returned $17. The guess it's better than nothing, but still a rip off.

This, just fill in what info you can and the relevant numbers.
I did it and three weeks later I got a full $81 unlimited card, which is good, because the one it replaced stopped working 3 days in.

This just happened to me last month.

The station agent cannot transfer your balance over to a new card, so you have to mail the card in and then about three weeks later you get something--I got a credit to my credit card that I used to buy the metro card. I'm not sure what you'll get if you don't have the receipt, maybe a replacement card. When you talk to the station agent, they are supposed to offer you an envelope and form to send it in to the MTA. The Astoria agent I talked to didn't though, and I had to go back and ask for it after calling the customer service number.

If you paid for your monthly card with a credit card, you can simply call them and they will give you a credit for the remaining days on the card (from when you call in). Just tell them you lost it.

I paid cash in the machine, unfortunately.

i did this once accidentally. i had to mail off the metrocard using the little pamphlet the station agent will give you. mine had about 3 weeks left on it as well, and they just mailed me a brand new 30 day card. you have to buy a new one in the meantime, though.

Actually I got a station agent to just transfer the balance once ... although my card was old not demagnetized and I was dressed pretty and gave him a cute smile.....

This JUST happened to me last week. Don't mail it in: call that "if you lost your monthly metrocard and you paid for it with a credit card" number (if you paid for it with a card) and they'll refund the money back to your card.

Idk if this helps. The last time this happened to me, I brought it to the station agent and he was just using the table to straighten it out in every way lol


But they should be able to use that number on your card and track it.
