Import Export Code (IEC) after GST

[lakush jain]

Do I need to register for IEC code or can I just use GSTIN number?

Below memo states that I can use GSTIN number but it is confusing that whether I still need to register with DGFT for IEC to consider my PAN number as IEC?

AI Summary

GSTIN as primary import identifier: use GSTIN for IGST credit and quote it in import documentation.
GSTIN is the primary transaction-level identifier for imports and must be quoted in Bills of Entry for IGST credit; where GSTIN is not applicable, PAN or UIN may be used and PAN is treated as the IEC for entities. Existing IECs need not be updated with GSTIN, and import/export operations require IEC registration with DGFT and acceptance by ICEGATE.
