Flagstar Bank
About Flagstar Bank
Flagstar Bank, N.A. is an American bank providing a broad range of financial services to individuals, families, and businesses. Its offerings include checking and savings accounts, lending, mortgages, commercial banking, private banking, and other financial products designed to meet personal and business banking needs.
Flagstar historically maintained major headquarters operations in Troy, Michigan, where it developed a strong presence and built a significant national mortgage-lending business. Over time, the bank’s corporate structure changed substantially through mergers and banking reorganizations, resulting in changes to its corporate operations and headquarters.
Today, current Flagstar materials identify the bank’s corporate headquarters at 102 Duffy Avenue, Hicksville, New York, rather than its former Michigan headquarters. While Michigan remains an important Flagstar operating market, Hicksville, New York, should now be treated as the bank’s current corporate headquarters.
