It's 1800SAMSUNG in the USA, other countries try samsung.com
http://www.samsungparts.com/ModelList.aspx?Catalog=Parts_and_Accessories&model=N920 seems to note 6 models. I'd get the full model number before the call.
I have lost my s pen and need to order a replacement.
So are all S pens the same? Can I order a note 4 s pen and will it fit in my note 5?
If I can only order a note 5 s pen, I have a model N920C but can only find s pens for N920T and N920N and etc. Will those pens fit in my note pen slot?
