It has been confirmed that Gloucester City and Oxford City have been moved across from National League South to the North for the forthcoming season.
The three other new teams Hereford will face next season are Farsley Celtic, Kettering Town and King's Lynn Town, who were all promoted from Step 3.
Clubs have seven days to appeal the decision and the league has to ratify it at its AGM.
