International numbering of Musnad Ahmad hadiths

I am searching for international numbering of Musnad Ahmad. I got the 2 books: > 1. The book whose chapters names are the names of Sahaba. > 2. The book whose chapters names are like "The chapter of Imaan, The book of faith and Islam, etc". Maybe there are more published books with different chapter names strategy.
Which Musnad Ahmad book has international numbering? I searched a lot but didn't find any answer. Can someone please help me to get the right **international numbering Musnad Ahmad book**?
