View detailsBuilt on the wings of Grumman Aircraft
Bethpage Federal Credit Union was chartered in 1941 to serve the employees of Grumman Aircraft Engineering Corporation — the Long Island company that built the F6F Hellcat, the F-14 Tomcat, and the Lunar Module that landed on the moon. For decades, membership was restricted to Grumman employees and their families. The credit union's name comes from the hamlet of Bethpage, New York, where Grumman's sprawling manufacturing complex once employed tens of thousands of workers.
When Grumman merged with Northrop Corporation in 1994 to form Northrop Grumman, the credit union retained its name and gradually expanded eligibility. Today anyone who lives, works, worships, or attends school on Long Island — as well as residents of several New York City boroughs — can join. That expansion transformed Bethpage from a defense industry credit union into the largest credit union in the New York metropolitan area, with over $12 billion in assets and more than 400,000 members.
Routing number
Bethpage Federal Credit Union's routing number is 221473958. The 221 prefix ties to the Federal Reserve Bank of New York, consistent with its New York charter. This applies to all Bethpage accounts — share accounts (savings), share draft accounts (checking), money market accounts, and certificate accounts — for direct deposits, ACH transfers, bill payments, and wire transfers.
A note on credit union terminology: what Bethpage calls a "share draft account" functions identically to a checking account. If you're setting up direct deposit with your employer, 221473958 is the number you need.
Long Island economics and the post-defense transition
Bethpage FCU's growth mirrors Long Island's broader economic transformation. When Grumman was at its peak, Long Island was a center of American aerospace and defense manufacturing. As that industry contracted — Grumman's Bethpage campus is now largely redeveloped — Long Island's economy shifted toward healthcare, education, financial services, and small business. Bethpage adapted by building out consumer lending products and small business services that serve this diversified economy. The decision to remain headquartered in Bethpage is a nod to heritage: the Grumman era is deeply woven into the community's identity.
Bethpage also sponsors the naming rights to Bethpage State Park's Black Course — one of the most famous public golf courses in the world and host of multiple US Open championships — giving the credit union brand visibility far beyond what a typical credit union achieves.
When your business needs more than a credit union
Bethpage serves its members well for personal banking and basic small business accounts. Businesses that need corporate cards with spend controls, real-time expense tracking, multi-user account management, and integrations with modern accounting platforms will find that credit union infrastructure wasn't designed for those use cases. Slash fills that gap — business-grade financial tools that let growing companies manage money with precision and visibility. Keep your Bethpage savings account earning above-market rates while running your business finances through a platform actually built for it.
