[4] In the late 1950s the bank began to open branches in the area, and in 1960 the name was changed to First National Bank of South Amboy-Madison Township to reflect the move of its headquarters to nearby Madison Township (later renamed Old Bridge Township[5]).

[7] In the mid-1980s, Amboy Bank became one of the first lenders in the United States to offer a biweekly mortgage.

[9] In 2003 it transitioned to offering accounts that could be opened online.

[10] In 1998, the Amboy Foundation was established to provide grants to community organizations that support education, civic, health, and social services.
