Verification of GST registrations strengthened: risk based scrutiny, document authentication, and mandatory physical verification where necessary. Officers must promptly scrutinize FORM GST REG 01 and uploaded documents for legibility, completeness and authenticity, cross verify addresses and identity proofs with public sources, and consult DGARM/GSTN risk ratings to apply heightened scrutiny to high risk ARNs and PANs with adverse registration histories; deficiencies must be addressed by electronic notice (FORM GST REG 03), responses examined (FORM GST REG 04), and unsatisfactory or absent replies lead to rejection (FORM GST REG 05). Physical verification is required where Aadhaar authentication is absent or where officers deem it necessary, and registrations granted on deemed approval or in high risk cases must be physically verified without delay.
