The National Credit Union Administration (NCUA) is the independent federal agency that charters and supervises federal credit unions throughout the United States and its territories.
NCUA administers the National Credit Union Share Insurance Fund (NCUSIF). Backed by the full faith and credit of the United States government, the NCUSIF insures the accounts in all federal credit unions and the substantial majority of state-chartered credit unions. NCUSIF insurance is equivalent to FDIC insurance offered by banks.

The insurance that NCUSIF provides credit union members is up to $250,000 on your individual accounts. If your account balance exceeds the coverage limit of $250,000, you have options for coverage that is separate from and in addition to the coverage available to your individual account.
