Football League clubs will have to interview at least one Black, Asian or ethnic minority candidate for a first-team manager's position from next season.
It follows an 18-month trial period, which saw clubs make a voluntary commitment to the rule.
The 'Rooney Rule' is an NFL policy that requires the league's 32 teams to interview BAME candidates for head coaching and senior operation roles.
"The EFL has today made a further commitment to improving equality in first-team football by introducing a recruitment code into regulation in order to help address the under-representation of BAME managers," an EFL statement read.
