Episcopal Charities of Long Island is a 501(c)(3) not-for-profit organization registered in New York State and governed by a board of directors who are clergy or parishioners within the Diocese of Long Island. Its ministry in the Diocese of Long Island is to raise and disburse funds to support the agencies and programs of the diocese.

The agencies and programs that are funded through ECLI are funded by the charitable donations received from individuals, congregations, businesses, and foundations, as well as income from invested funds.

Because income from invested funds is used to pay for modest administrative costs, 100% of every dollar contributed to ECLI through its appeals is applied to agency and program support.
