All the details: MLS Primary Transfer Window open through May 5

It’s been a wild MLS silly season with a flurry of big-name signings, trades and rumors from across the globe.

But the actual window to sign players hadn't yet opened. That changes today, Feb. 12, when the Primary Transfer Window begins and runs through May 5.

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 Secondary Transfer Window extends from July 7 through Aug. 5. For all of the major 2020 MLS season dates, learn more here.
