The Premier League summer transfer window will run between 27 July and 5 October subject to FIFA approval.
The period will also cover the English Football League and both the EPL and EFL say a domestic window will operate between 5-16 October.
“During this window, clubs will only be able to trade with EFL clubs (either loans or permanent registrations),” said a Premier League statement.
“No transfers can take place between Premier League clubs in this period.”
The EFL added: “The window for international registrations closes at 23:00 BST on Monday, 5 October, with an agreement in place with the Premier League for an extended two-week domestic-only window, which will close at 17:00 on Friday, 16 October.”
No date has yet been fixed for the start of the 2020-21 season.
Reports suggest that the new season would most likely start on 12 September immediately after September’s round of international games.
