Eastern Bank Headquarters & Corporate Office

About Eastern Bank

Eastern Bank is a Massachusetts-chartered bank founded in 1818 and headquartered in Boston. It provides personal banking, business banking, commercial banking, mortgages and home equity lending, deposit products, treasury management, private banking, and wealth-management services. Its publicly traded parent is Eastern Bankshares, Inc., a Massachusetts corporation formed in 2020 and listed on Nasdaq under ticker EBC.

Eastern has expanded substantially through recent acquisitions. Its 2024 combination with Cambridge Trust added major wealth-management and private-banking capabilities, and its merger with HarborOne became effective in November 2025, broadening Eastern’s branch network and lending operations. Current October 2026 investor materials describe Eastern as operating more than 125 branch locations across eastern Massachusetts, southern and coastal New Hampshire, and Rhode Island.

As of June 30, 2026, Eastern reported approximately $31.1 billion in assets. It is led by Denis K. Sheahan, Chief Executive Officer, with Quincy L. Miller serving as Vice Chair, President and Chief Operating Officer. Eastern’s principal executive office and current corporate headquarters are located at 125 High Street, Boston, MA 02110.

How to Reach a Real Person at Eastern Bank

Personal banking customers should call 1-800-EASTERN (1-800-327-8376). Live Customer Service representatives are available Monday through Friday from 7:00 AM to 8:00 PM and Saturday from 9:00 AM to 3:00 PM. Have the account number, customer identification information, recent transaction details, and any existing case number available before calling.

Business customers should use 800-333-8000, while wealth-management clients should call 866-602-1522. For a branch-specific matter such as a cash transaction, teller interaction, safe-deposit concern, or local account issue, contacting or visiting the branch directly can be faster than starting with the corporate office.

If the problem concerns suspected fraud, unauthorized debit-card activity, or identity theft, call 1-800-EASTERN immediately or visit a branch. Eastern advises customers to keep detailed records of all fraud-related conversations, confirm important communications in writing, and retain copies of correspondence and supporting documentation.

How to File a Complaint Against Eastern Bank

Eastern Bank complaints may involve checking or savings accounts, debit cards, mortgages, loan servicing, fees, fraud, branch service, online banking, wealth management, commercial banking, or another financial product. Before escalating, collect statements, transaction records, receipts, loan documents, screenshots, emails, branch information, and prior complaint numbers.

Step 1: Contact Customer Service

Call 1-800-EASTERN (327-8376) and explain the complaint clearly. Provide the relevant account or loan information, transaction dates, disputed amounts, and the resolution requested. Ask the representative to document the issue and provide a reference number whenever available.

Step 2: Contact the Relevant Department

Use 800-333-8000 for business banking, 866-602-1522 for wealth management, or the appropriate branch for local transactions. Mortgage and loan customers can use the regular Consumer Service Team unless their statement identifies a specific servicing provider. Routing the issue to the department that controls the product generally produces a faster review.

Step 3: Request Supervisor or Management Review

If the first representative cannot resolve the dispute, request supervisor or management review. Provide the previous case number and summarize the facts without restarting the complaint from scratch. For a branch complaint, ask the Branch Manager to review the matter. For commercial or wealth-management issues, request the relevant relationship manager or senior service team.

Step 4: Use the Company’s Written Complaint Channel

Eastern provides an Eastern Cares Feedback process through its Customer Service resources. Written feedback is useful when the complaint requires supporting documents or a detailed timeline. Customers can also write to Eastern Bank, Customer Service Center – EDG2-02, P.O. Box 4071, Wakefield, MA 01880-5371.

Step 5: Contact Corporate Headquarters

For a serious unresolved corporate complaint, send correspondence to Eastern Bankshares, Inc. / Eastern Bank, 125 High Street, Boston, MA 02110. Include copies of statements, complaint references, transaction details, and all previous responses. Clearly identify the outcome being requested and keep proof that the correspondence was delivered.

Step 6: Use the Specialized Complaint or Dispute Department

Fraud or identity-theft complaints should be reported immediately through 1-800-EASTERN and may require closing or replacing affected accounts. Wealth-management complaints should be raised with the Cambridge Trust Wealth Management Client Service Center. Mortgage servicing disputes should be directed to the servicer identified on the current loan statement if the loan is serviced through LoanCare or another designated provider.

Step 7: File With the Appropriate Regulator

Eastern Bank is regulated by authorities including the Massachusetts Commissioner of Banks, FDIC, Federal Reserve Board, Consumer Financial Protection Bureau, and New Hampshire Banking Department, depending on the entity, location, and issue. A complaint concerning deposit accounts, lending, mortgage servicing, or another regulated banking activity should be filed with the regulator that has jurisdiction over that product.

Step 8: Use Consumer Protection or Financial Dispute Options

Consumers may also submit qualifying financial complaints to the Consumer Financial Protection Bureau, while fraud can involve local police, the Federal Trade Commission, credit bureaus, and other agencies. Eastern itself recommends placing fraud alerts with the major credit bureaus when identity theft is suspected. Payment disputes may additionally involve the relevant card network or another financial institution.

Step 9: Consider Formal Legal or Arbitration Procedures

If internal review and regulatory channels do not resolve a serious banking dispute, review the applicable deposit agreement, loan agreement, mortgage documents, wealth-management contract, and dispute-resolution provisions. Depending on the issue, options may include mediation, arbitration, court proceedings, or another contractual remedy. For substantial financial loss or complex lending disputes, obtaining advice from a qualified attorney may be appropriate.
