Mass Bay Credit Union will never call and ask you for account or other personal information. We recognize that there are people hoping to gain access to your deposit accounts, debit card, credit card and other personal information to make purchases and access your money. Do not become a victim. If someone calls you, and the caller ID is our phone number, we ask that you do NOT give out or confirm your personal information, account numbers, PINs, social security or other sensitive information. Hang up, do not press re-dial, and call us at 617-269-2700. Do not be coaxed via text or email either! We want to keep you safe from fraudsters.
