If you indeed count the independents and non-denoms…then you it would be over 30,000 now since the count was done.

Independents (about 22,000 denominations)
Let’s deal with these first, since this is the largest mega-bloc (22000+ “denominations” of the total 33000+). These are broken down into various large groups, and their lists and numbers span from the bottom of page 16, through page 17, and most of page 18. I’m not going to type all of these since the list is quite long – much longer than any of the groupings in the other mega-blocs which are listed below in full. I will quote a major sampling of these “Independent” Christian groups, and still try to cover the whole list:
While the World Christian Encyclopedia does refer to “only” 9000 or so denominations as “Protestant” the source also includes 22,000 or so denominations as “Independent” and if you look at the names of these “Independent” groups above, you’ll see most of them are clearly Protestant (the “Apostolic”, the “Charismatic”, the “Full Gospel”, the house or home churches, the pentecostals, probably all the TV/radio Christians, and all the independents of other Protestant denominations listed, etc). None of these are Catholic or Orthodox, but there appear to be some renegade Orthodox, Anglicans, and schismatic Catholics among the “Independents.” The largest of these Independent Christians are “White-led charismatic” (17,478,000 members [year 1995], in 2856 separate denominations [year 2000]), “African independent pentecostal” (18,943,000 members [year 1995], in 5385 separate denominations [year 2000]), and “African neocharismatic of mixed traditions” (1,500,000 members [year 1995], in 3333 separate denominations [year 2000]). These three are all Protestant (neither Catholic, nor Orthodox) and account for more than half (53%) of the 22,000 “Independent” denominations.
Another section of these “Independents” with a decent number of denominations include (ordered by smallest to largest denominations, year 2000):
