Fraud Alerts


Debit Card Fraud is a worldwide problem, and as a result we have placed restrictions on our debit cards in order to protect you and MCU.

Debit Card Restricted Locations

We have no restrictions on your card in the US. It is not necessary to call us before you travel within the US to a location you visit often. However, if you are traveling outside of your normal patterns, your card may be blocked.  Please make sure you have an updated cell phone number with MCU, because you may be called to verify your recent transaction history to protect your card from being blocked. If you prefer, feel free to call the office before you travel and your account will be noted.

If you are traveling abroad, please notify us in advance.  Because there are high fraud volumes in many countries, your transactions may not go through unless we place a note on your account. We apologize for any inconvenience and appreciate your understanding and patience. These steps are necessary to protect the integrity of you your card.

Fraud Protection

Members Credit Union will never authorize an outside company or organization to contact you by phone or internet to request account holder information. If you should be contacted in such a manner, please hang up and call the credit union immediately. If a credit union staff member contacts you for account information, we will offer you the opportunity to call us back at 203-622-6050 in Cos Cob.

The credit union is alerted of attempted fraud situations that affect the financial industry on a regular basis. We would like to pass on the information to you so you can be aware of what to look for in case you are approached by someone who wants to obtain your information and use it for illegal purposes.

2020 SCAM ALERT! One of our members received an e-mail from the National Credit Union Administration asking for debit card information. This is a phishing fraud e-mail. Please don't give out credit union account information in reply to any e-mail.

E-mail and telephone scams are on the rise. Never give out account or personal information to anyone requesting it via e-mail.

Members Credit Union will never ask you to provide account information via e-mail. If you should receive an e-mail requesting such information, contact the credit union immediately. If you receive a telephone call requesting account or personal information, do not provide it unless you are initiating the telephone call.

2021 SCAM ALERT! At least three MCU Members have received calls telling them that their computer has been compromised and that the individual on the phone will repair their computer, but they need to be paid first. The members were told that they couldn’t accept a credit card because of the compromise and they needed to drive to a close store, buy gift cards and give the person on the phone the numbers of the cards in payment. Sound suspicious? These scam artists were so convincing that two of the members actually followed their directions, got in their cars with the person still on the phone, bought the cards and gave the callers the card numbers! PLEASE, if you ever get a call like this, HANG UP THE PHONE! Neither the police, or MCU will be able to get your money refunded, and you will lose whatever you spent.
