State code alignment with GSTN implemented-trade must use revised codes in customs declarations to avoid interface mismatches. Alignment of state code lists in ICES from the RBI list to the Census/GSTN codes has been implemented via an NIC RES package update; trade must use the new codes in Bills of Entry and Shipping Bills to ensure correct State of Origin and registration declarations and to prevent ICEGATE-side mismatches, and report any difficulties to the System Manager at the Custom House.
