📋 Visa CEDP Product 3 — April 2026 Update
Visa launched Commercial Enhanced Data Program (CEDP) Product 3 in April 2025. Note: Visa began sunsetting the legacy Level 2 enhanced-data program in April 2026. Merchants processing B2B volume should confirm CEDP migration status with their acquirer. Mastercard's Commercial Data program remains the parallel qualification path.
