Eastern Bank Routing Number: America

Two hundred years of mutual ownership, then a bell on Wall Street

Eastern Bank was chartered in 1818 in Salem, Massachusetts - three years after the Battle of Waterloo and four decades before the Civil War. For 203 years, it operated as a mutual bank, meaning it had no shareholders and was technically owned by its depositors. That structure made Eastern one of the most conservative, community-rooted financial institutions in the country. It survived the Panic of 1837, the Great Depression, the savings and loan crisis, and the 2008 financial crisis without ever needing a bailout or outside capital infusion.

Then, in October 2021, Eastern Bank did something that seemed almost unthinkable for an institution with two centuries of mutual heritage: it went public. The IPO raised approximately $1.8 billion, making it one of the largest bank IPOs in US history. Trading on the NASDAQ under the ticker EBC, Eastern Bank transformed overnight from a depositor-owned mutual into a publicly traded corporation, a transition that fundamentally altered its governance, capital structure, and strategic options.

Eastern Bank

Eastern Bank's routing number is 011301798. The 011 prefix identifies it as processed through the Federal Reserve Bank of Boston, reflecting the bank's Massachusetts charter. This number applies to all Eastern Bank deposit accounts - personal and business checking, savings, and money market accounts. It has remained unchanged through the IPO and the bank's transition from mutual to stock ownership.

For wire transfers, Eastern Bank uses the same routing number domestically. The bank serves eastern Massachusetts and southern New Hampshire, with a concentration of branches in Greater Boston, the North Shore, South Shore, and Merrimack Valley.

The 10% pledge that turned an IPO into philanthropy

What made Eastern Bank's IPO genuinely unusual was not its size but what the bank did with the proceeds. Eastern committed 10% of its IPO value - approximately $180 million - to the Eastern Bank Foundation, making it one of the largest charitable commitments in New England history. The foundation directs those funds toward affordable housing, racial and economic justice, workforce development, and small business support across the communities Eastern serves.

This was not a marketing stunt. Eastern Bank had been one of the most philanthropically active banks in the country long before the IPO, consistently ranking among the top corporate charitable givers in Massachusetts relative to its size. The 10% pledge was an extension of a culture that viewed community investment not as a compliance obligation but as a core business strategy. For Eastern, the IPO was a way to fund two centuries of community banking values at a scale that mutual ownership could never achieve.

New England banking in a consolidation era

The New England banking landscape has been reshaped by decades of consolidation. Fleet Boston was absorbed by Bank of America. Sovereign became Santander. Citizens was bought by Royal Bank of Scotland (and later re-IPO'd). Against this backdrop, Eastern Bank's independence is increasingly rare. It is one of the few remaining large, locally headquartered banks in Massachusetts - a distinction that matters to the small businesses and nonprofits that depend on local lending relationships.

Eastern's commercial banking team focuses on middle-market companies, commercial real estate, and nonprofit organizations. The bank's lending decisions are made locally by bankers embedded in the communities they serve, a model that relies on institutional knowledge of Boston's neighborhoods, its real estate cycles, and the economics of industries like healthcare, education, and life sciences that define the Greater Boston economy.

Legacy values, modern expectations

Eastern Bank has earned its reputation over two centuries of steady, community-focused banking. But longevity alone does not solve the operational challenges facing modern businesses: real-time visibility into spending, automated expense workflows, corporate cards with programmable controls, and banking infrastructure that does not end at the New Hampshire border. Slash brings those capabilities to the businesses that need them, pairing the financial discipline of institutions like Eastern with the kind of software-first experience that today's finance teams expect.
