Need to find my new shade

[4evrskiz]

I love love Lancôme Teint Idole Ultra wear foundation! Every time I wear it I get so many compliments on my skin and how flawless it looks and the shade is SPOT ON! No mixing required. Now that’s they’ve changed shades mine is no longer there ( 420 Bis N). I don’t want to have to go into a store and get shade matched again. 
Any recommendations on what new shade would equal what I’ve been using?

@4evrskiz have you tried Sephora's shade match ?  It is still best to try the products in store as it isn't always a correct match.

I was hoping to avoid that if I could!  But I guess that's my only option at this point.  I was hoping that there would be a shade comparable to what I have been using.
