Write a Letter to a bank informing it about the loss of your credit card or ATM card and request for a replacement.

Hello,

Re: Account No.

This is to state that I recently lost/misplaced my card on the above-referenced account. The card carried the number . In view of the situation, I request you to cancel that card and issue me a replacement card as soon as possible. In addition, the use of the lost card should not be authorized under any circumstances.

I would appreciate your prompt attention to my request. In case you have any queries regarding the matter, please do not hesitate to contact me.

Regards,
