During registration, you can add a field in which the user must enter a code that is given above (also via paper letter) and that is different for each user?
In practice it would be an activation code that identifies the user; a kind of customer number.
You'd need a database to store those activation codes if they're supposed to be unique and 1 time use. You'd then need CB Query Field and its Query Validation added to a Text field to validate the value they supplied exists in that database and hasn't been used yet. CB Invites is the easier approach by just sending them an invite via Email that gives them an invite code, which they'd use the invite code field (set to display on registration and required); I suppose you could use it without the email though. Alternatively if the activation code doesn't have to be unique and is the same for everyone just make a text field that validates against that 1 value.

The invite code is unique per invite. So you'd have the admin send an invite to someone using their email address. That person would then click that invite URL to register which will fill out the invite code field (if set to display on registration) to accept the invite. If you set the invite code field to required then it's mandatory for someone to be invited to join the site. You can set the access of the invite tab to your admins view access level if you only want to allow admins to invite people. This would be the easiest approach.
