These are the phone and email addresses we use to send you a secure code if the device you log in from is not recognized.

It’s important that we have your latest address, phone number and email address on file so we can reach you promptly.
A: We monitor online banking activity closely and may contact you if we notice login attempts, bill payments or external transfers that are out of the ordinary. Risk Management Specialists from The Merrimack or from our online banking service providers will only contact you to verify that unusual activity was authorized by you and will not ask for confidential information, such as your online banking username and password. If you’re ever uncertain whether a communication you received was made by or on behalf of The Merrimack, please call us directly at 800.541.0006. Please also be sure to keep your contact information up to date so we can reach you promptly.
