Pre-registration physical verification to prevent fake GST registrations, with suo-moto cancellation for functionally non-existent registrants. Proper Officers must prevent any registration application from becoming deemed approved through inaction and are accountable for failures. Mandatory pre-registration physical verification is required where Aadhaar OTP authentication is not completed; where OTP is completed, verification is required on a risk-based data-analytics basis or discretionally with Circle Head approval. Post-registration, immediate physical verification is required for unverified registrants or on enforcement leads; adverse findings of functional non-existence trigger suo-moto cancellation proceedings following natural justice and may be applied retrospectively.
