If your DCU account is locked, a card is missing, a transaction looks unfamiliar or a loan payment needs attention, use the secure route that matches the problem. Account-specific questions should go through Digital Banking or DCU’s verified telephone number—not the public email form or a review.

Quick contact: Call DCU’s Information Center at 1-800-328-8797. DCU’s current contact page lists live-specialist hours of weekdays from 7 a.m. to 11 p.m. and weekends from 8 a.m. to 7 p.m. Eastern Time. Self-service telephone banking is available 24 hours a day.

DCU and First Tech Merger Update

Digital Federal Credit Union and First Technology Federal Credit Union legally merged on January 1, 2026, forming one credit union named First Technology Federal Credit Union. During the 2026 integration period, the organization continues operating through two divisions: Digital Federal Credit Union, or DCU, and First Tech Federal Credit Union.

DCU members should continue using DCU.org, DCU Digital Banking and DCU contact information unless the credit union provides different instructions. Do not assume a communication about the merger is legitimate merely because it uses both names. Review the official DCU and First Tech merger information before acting on an unexpected message.

DCU states that member accounts remain federally insured by the National Credit Union Administration. Coverage depends on account ownership and other factors; the NCUA share-insurance resources explain the rules.

Best DCU Support Route by Issue

Digital Banking lockout: Call 1-800-328-8797. Start at DCU.org rather than a link received by text or email.
Checking, savings or account question: Use a secure message inside Digital Banking or call the Information Center.
Auto or personal loan question: Call the Information Center and choose the loan-related option. Have the loan type and requested action ready, but do not enter confidential information until the call is verified.

Loan application status: Use the application-status route provided with the application or contact the Information Center.
Mortgage or home-equity issue: Use the servicing contact shown on the current statement or inside Digital Banking, because servicing and application routes may differ.
Lost or stolen Visa card: Call 1-800-847-2911 immediately.
Suspected debit-card, credit-card or account fraud: Call DCU immediately at 1-800-328-8797.

Transaction dispute: Sign in to Digital Banking, open Membership, choose Services and select Dispute a Transaction for the applicable transaction type.
Branch service: Use the official locator to check the address, services, hours and appointment availability for the specific branch.

DCU Fraud, Phishing and Urgent Card Help

Urgent fraud warning: DCU says it will never ask for your Digital Banking username, password or PIN. Do not share a one-time passcode or verification code with an unsolicited caller, even if caller ID displays DCU’s number. Hang up and independently call 1-800-328-8797 using the number published on DCU.org or printed on your card.

DCU warns that scammers may spoof its telephone number and claim to work for its fraud team. Do not reply to an unexpected alert, click its link, install software, move money to a “safe” account or provide login credentials. Access the account by typing DCU.org yourself or using the installed DCU app.

Forward suspected phishing email: phishing@dcu.org
Official DCU fraud guidance: DCU Privacy and Fraud Resources
Identity-theft recovery: IdentityTheft.gov

If money or account access may be at risk, contact DCU immediately. A public comment does not freeze a card, stop a transfer, dispute a transaction, preserve a claim deadline or notify the credit union.

DCU Disputes, Payments and Loan Documentation

For an unfamiliar transaction, first determine whether it is pending or posted and whether another authorized user may recognize it. Then use DCU’s secure dispute process or call promptly. Keep the merchant name, amount, date, transaction type and any contact with the merchant, but do not post those details publicly.

For a loan payment, payoff, title, insurance or credit-reporting concern, identify the exact loan and requested resolution. Save payment confirmations, statements, notices and secure messages. Ask for a case or reference number and obtain written confirmation of any payment arrangement, fee decision, payoff instruction or promised correction.

Do not send a payment, payoff check, title, dispute package or original document to a general address unless DCU confirms that the address applies to the specific account and purpose.

DCU Mailing and Delivery Addresses

USPS letters and standard mail: DCU, PO Box 9130, Marlborough, MA 01752-9130
FedEx, UPS, overnight and courier deliveries: DCU, 853 Donald Lynch Boulevard, Marlborough, MA 01752-4704

The former page listed 220 Donald Lynch Boulevard. DCU’s current website instead publishes 853 Donald Lynch Boulevard for deliveries. Confirm the correct destination before mailing anything sensitive, time-critical or account-specific.

How to Escalate a DCU Complaint

Use the department connected to the account, card, loan, transaction or branch.
Describe the problem, important dates and requested resolution briefly.
Ask for a case or reference number and expected follow-up date.

Send supporting documents only through the secure channel DCU identifies.
Keep statements, receipts, notices, secure messages and call notes.
If the issue remains unresolved, request supervisor or complaint review and ask for the appropriate written escalation process.
