According to Daniel Wallace:

The total number of catalogued Greek New Testament manuscripts now stands at 128 papyri, 322 majuscules, 2926 minuscules, and 2462 lectionaries, bringing the grand total to 5838 manuscripts.

CSNTM has also “discovered” two more minuscule manuscripts in the summer of 2013 on our European expeditions which will most likely receive their Gregory-Aland numbers in due time.
