Several key MLS dates in 2020, including both the winter and summer MLS transfer windows, were officially released ahead of the new regular season which kicks off on February 29.

The transfer windows are the periods in which MLS teams can officially register any new players who were previously under contract with clubs based outside MLS and for which an International Transfer Certificate (ITC) is required. While deals may be agreed upon outside these windows, the transfer and receipt of an ITC are required in order to officially add a player to a roster, thus allowing him to be eligible for official competitions.

All in-season trades between MLS clubs must take place within these transfer windows.

The 2020 dates are roughly in line with the same windows in 2019 (February 13 - May 7 / July 9 - August 7) and 2018 (February 7 - May 1 / July 10 - August 8).

Primary Transfer Window: Wednesday, February 12 – Tuesday, May 5, 2020

Secondary Transfer Window: Tuesday, July 7 – Wednesday, August 5, 2020
