Bethpage Federal Credit Union Routing Number: From Grumman

Built 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 in Bethpage FCU 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 its membership 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 Bethpage FCU. That expansion transformed it 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.

The routing number and what it means for members

Bethpage Federal Credit Union's routing number is 221473958. The 221 prefix identifies it as processed through the Federal Reserve Bank of New York, consistent with its New York charter. This routing number applies to all Bethpage accounts - share accounts (savings), share draft accounts (checking), money market accounts, and certificate accounts.

Credit union terminology can be confusing for members accustomed to traditional banks. What Bethpage calls a "share draft account" functions identically to a checking account, and the routing number works the same way for direct deposits, ACH transfers, bill payments, and wire transfers. If you are 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 one of the centers of American aerospace and defense manufacturing. As that industry contracted and consolidated - Grumman's Bethpage campus is now largely redeveloped - Long Island's economy shifted toward healthcare, education, financial services, and small business. Bethpage FCU adapted by building out consumer lending products (auto loans, home equity, mortgages) and small business services that serve this diversified economy.

The credit union's decision to remain headquartered in Bethpage - even as much of Long Island's commercial activity has shifted to the western suburbs of Nassau County - is a nod to its heritage. The Bethpage name still carries weight on Long Island, where memories of the Grumman era are deeply woven into the community's identity.

Credit union advantages and the New York competitive landscape

As a federal credit union, Bethpage is tax-exempt and member-owned, which allows it to offer consistently lower loan rates and higher deposit rates than the commercial banks that dominate the New York metro market. In a region where Chase, Citibank, and Bank of America control the majority of consumer deposits, Bethpage has carved out a loyal following by competing on price and service rather than branch count or brand awareness.

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 the host of multiple US Open championships. This sponsorship gives Bethpage FCU brand visibility far beyond what a typical credit union achieves, connecting it to one of Long Island's most iconic landmarks.

When your business needs more than a credit union

Bethpage FCU serves its members well for personal banking and basic small business accounts. But 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 was not designed for those use cases. Slash fills that gap - providing the business-grade financial tools that let growing companies manage their money with the precision and visibility that consumer-oriented institutions simply do not offer.

You can keep your Bethpage savings account earning above-market rates while running your business finances through a platform actually built for it.
