From Season 2021/22 it will be mandatory for all players under the age of 16 to have a parent record attached. The NEHYL are making this mandatory for this coming season.
For club/team officials to attach a parent, the details required (for the parent) are shown in the screenshot below - a FAN is generated if none exists based on the search criteria shown. The FA have now created a new feature to add a parents email address to a player which sends them an email to confirm the player and attach the record. This avoids the need to request a parent's DOB.
