The 20 teams across the two divisions, who have been out of action since January 11, have been given approval from the Scottish government to return providing the players and staff undertake regular Covid testing.
The SFA put a proposal to the Scottish Governemnt which was approved by First Minister Nicola Sturgeon on Tuesday.
Scottish FA President Rod Petrie commented: “We are pleased that the First Minister has again recognised the importance of football in Scotland.
“The decision to temporarily suspend parts of the professional game played by predominantly part-time teams was not an easy one to take.
"None the less, given the sharp rise in infection rates caused by new strains of the virus at the start of the year, it was the right thing to do to assist the national effort to reduce its prevalence during lockdown.
“While we are pleased to see the return of these leagues, there remain significant numbers unable to return to play, including the remaining levels of the professional pyramid, elite youth football, club youth football and our amateur and grassroots clubs across both the male and female game."
While League 1 and 2 clubs are still having regular meetings to discuss how and when they will complete their league campaigns, the governing body wasted no time in sending out a revised fixture list for the Scottish Cup.
The competition will resume on Tuesday, March 23 in order to complete the outstanding ties from the Second Round before the Third Round is played on the weekend of April 3.
The last two weekends in April will see the Fourth and Fifth Rounds of the competition completed prior to the Semi-Finals which will be held across the weekend of May 8.
The 2021 Scottish Cup Final will bring the curtain down on the season at Hampden Park on Saturday, May 22.
That means that Stranraer, who booked their place in the fourth round before the shutdown, will find out later this month whether they will face Brora Rangers or Hearts on April 3.
