National League is the USYS conferences at U13 and older.
EDP manages the mid Atlantic and north east conferences.
“ The US Youth Soccer South Atlantic Conference, Managed by EDP Soccer, consists of teams primarily from Maryland, Delaware and Virginia. The top teams in the South Atlantic Conference top tier divisions will earn advancement to the US Youth Soccer Regional Championships (NCS) and automatically qualify for National League P.R.O.”

Separately EDP has the EDP league for 11U-19U Boys & Girls. The top EDP teams are be promoted up to the national league conferences.
Somehow USYS is also affiliated with Elite64 (coppermine is the only local team) that is separate but affiliated with the national league conferences and national championship.
to further confuse USYS ‘advised’ GA whatever that meant, however GA was not part of the national league pyramid
US club soccer is completely separate closed pyramid that sanctions ecnl leagues
But Don’t worry there will something new to tempt clubs and parents next year. The joy of a non unified youth soccer pyramid.
