Do you need to display it before you create it?

In this case use default with Closure and get the data/logic from db.

Otherwise use the mutateFormDataBeforeCreate hook

this is if you want to create it after the record is saved in the db.

User model:

    public static function boot()
    {
        parent::boot();

        self::creating(function ($model) {
            // ... code here
        });

        self::created(function ($model) {
            // USER00001
            $model->special_identifier = 'USER' . str_pad($model->id, 5, '0', STR_PAD_LEFT);

            $model->save();  // You need to save again since this happens after creation
        });

        self::updating(function ($model) {
            // ... code here
        });

        self::updated(function ($model) {
            // ... code here
        });

        self::deleting(function ($model) {
            // ... code here
        });

        self::deleted(function ($model) {
            // ... code here
        });
    }

    public static function boot()
    {
        parent::boot();

        self::creating(function ($model) {
            // ... code here
        });

        self::created(function ($model) {
            // USER00001
            $model->special_identifier = 'USER' . str_pad($model->id, 5, '0', STR_PAD_LEFT);

            $model->save();  // You need to save again since this happens after creation
        });

        self::updating(function ($model) {
            // ... code here
        });

        self::updated(function ($model) {
            // ... code here
        });

        self::deleting(function ($model) {
            // ... code here
        });

        self::deleted(function ($model) {
            // ... code here
        });
    }
