Millwall and the EFL will collaborate in a bid to repair "reputational damage" caused by a "minority" of their supporters.
The club's policy for selling away tickets will be reviewed after some of the Lions' supporters invaded the pitch at the end of the play-off final victory over Bradford at Wembley in May.
The offending fans were criticised by Millwall match-winner Steve Morison as well as Bradford manager Stuart McCall.
A Football League statement read: "The EFL and the club will work on specific measures in relation to Millwall supporters attending fixtures at other EFL clubs. This initiative will see, amongst other things, the EFL and Millwall collaborate on how tickets are sold for away games.
"In the event Millwall qualify for any future EFL final at Wembley, the EFL and the club will review ticketing, security and stewarding arrangements, giving full consideration to any previous issues that have taken place at the National Stadium before a final plan is put into place."
Millwall chief executive Steve Kavanagh has been in regular contact with Football League chief Shaun Harvey since the events of the play-off final and the club is adamant the measures will be "fair and proper for the club's core supporters who provide outstanding backing of the team week in, week out, season after season."
Millwall will start the new league season at Nottingham Forest on Friday.
