GST migration special procedure: jurisdictional nodal officer nominated; contact details provided for taxpayer migration assistance. The notification implementing the special procedure for taxpayers with provisional IDs nominates a jurisdictional nodal officer to assist completion of migration; Annexure A supplies the officer's designation, office address, telephone and email for IT grievance redressal, and the Trade Notice directs commissioners and trade associations to circulate these contact details to officers and assessees, superseding the earlier Trade Notice.
