GST registration base campaign requires trader enumeration, officer verification, help desks, and strict compliance with filing timelines. A special campaign was launched in Uttar Pradesh to increase the GST registration base by completing trader enumeration in municipal bodies, wards, major markets and gram panchayats with population above 2,000. Zonal officers were required to allocate areas for verification, complete prescribed percentages of verification by senior officers, maintain a non-overlapping visit schedule, and upload visit and verification data in the specified formats. The circular also required timely completion of enumeration, data feeding, certificates, help desks, awareness activities, and full compliance with the registration campaign.
