A notice to all SAT members on communication received from ECSA regarding their transition to ECSA Digital Certificates. ECSA is replacing paper-based certificates with new digital certificates powered by PrivySeal to enhance security, transparency, and real-time verification of professional registration in South Africa. These digital certificates are tamper-proof and verifiable online and will be the only accepted proof of good standing after December 31, 2025.
