Across six public releases, approximately 3,000 translated VENONA messages were made public.
Notes on verification
Confirmed by NSA's own official history publication and NSA Cryptologic Foundation records, plus corroborating CIA/NSA joint publication figures and Wikipedia citing Benson's history. Multiple independent government and secondary sources agree on both the six-release structure and the ~3,000 message total.
