Due to only Stevenage being relegated from League Two, Maidenhead (who finished 21st in the National League) stayed up, meaning that only three teams were relegated. Two of of those teams - AFC Fylde and Chorley - drop into the North. No teams have been promoted to National League North due to all Step 3 leagues being declared null and void due to the coronavirus pandemic.
As it stands the National League North teams for 2020/21 are...
AFC Fylde
AFC Telford United
Alfreton Town
Blyth Spartans
Boston United
Brackley Town
Bradford (Park Avenue)
Chester
Chorley
Curzon Ashton
Darlington
Farsley Celtic
Gateshead
Gloucester City
Guiseley
Hereford
Kettering Town
Kidderminster Harriers
Leamington
Southport
Spennymoor Town
York City
