View detailsTwo 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, owned by its depositors with no shareholders. That structure made it 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.
Then in October 2021, Eastern 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. Eastern Bank transformed overnight from a depositor-owned mutual into a publicly traded corporation on NASDAQ under the ticker EBC.
Routing number
Eastern Bank's routing number is 011301798. The 011 prefix ties to the Federal Reserve Bank of Boston, reflecting the bank's Massachusetts charter. This applies to all Eastern Bank deposit accounts — personal and business checking, savings, and money market accounts — and has remained unchanged through the IPO and the transition from mutual to stock ownership. The same routing number applies to domestic wire transfers. Eastern serves eastern Massachusetts and southern New Hampshire, with branch concentration in Greater Boston, the North Shore, South Shore, and Merrimack Valley.
The 10% pledge that turned an IPO into philanthropy
What made Eastern's IPO genuinely unusual was what the bank did with the proceeds. Eastern committed 10% of its IPO value — roughly $180 million — to the Eastern Bank Foundation, 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. This wasn't a marketing move. Eastern had been one of the most philanthropically active banks in Massachusetts long before the IPO, consistently ranking among the top corporate charitable givers in the state relative to its size. The 10% pledge was an extension of a culture that viewed community investment as core strategy, not compliance.
New England banking in a consolidation era
The New England banking landscape has been reshaped by decades of consolidation — FleetBoston absorbed by Bank of America, Sovereign becoming Santander, Citizens bought by Royal Bank of Scotland. Against that backdrop, Eastern'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, with lending decisions made locally by bankers who understand Boston's neighborhoods, real estate cycles, and the economics of healthcare, education, and life sciences.
Legacy values, modern expectations
Eastern Bank has earned its reputation over two centuries of steady, community-focused banking. But longevity alone doesn't solve the operational challenges facing modern businesses — real-time visibility into spending, automated expense workflows, corporate cards with programmable controls, and banking infrastructure that doesn't end at the New Hampshire border. Slash brings those capabilities to businesses that need them, pairing the financial discipline of institutions like Eastern with the software-first experience today's finance teams expect.
