The EFL announced the increase following its annual general meeting on Friday, when clubs approved a number of regulation changes which will come into effect immediately.
As part of the new substitution rules, each club is only permitted a maximum of three opportunities to make changes during a fixture, plus an opportunity at half-time.

The EFL has also confirmed a home club will now be able to wear its ‘away’ or third kit, where a clash may occur that would make it difficult for people who are colour blind to differentiate between the kits worn by both teams.
The amendment also allows clubs to further ‘mix and match’ elements of their registered kits in order to avoid kit clashes.
The EFL will also play a more active role in helping clubs identify where a potential ‘colour blind kit clash’ may occur, in order to give them adequate notice so that all necessary arrangements can be made in advance. Meanwhile, Millwall chief executive Steve Kavanagh has been appointed to the EFL board following the election of a new Championship representative.
Kavanagh, who previously served as the Championship’s alternate director, joins North End’s Peter Ridsdale and Neil Bausor (Middlesbrough ) as Championship representatives . He succeeds Nicholas Randall QC following Nottingham Forest’s promotion to the Premier League.
League One and League Two representatives Jez Moxey (Burton Albion), Steve Curwood (Fleetwood Town) and John Nixon (Carlisle United) have been duly reappointed and will continue in their roles subject to promotion and relegation.
The EFL also added a disqualifying condition in its Owners and Directors’ Test for those convicted of a hate crime: defined as an offence that is considered to be aggravated in accordance with the Crime and Disorder Act 1998 and the Sentencing Act 2020.
