An Importer-Exporter Code (IEC) is an essential business identification number required for both exporting from and importing to India. No individual or entity can engage in export or import activities without obtaining an IEC, unless they are specifically exempted. Following the implementation of GST, the Importer-Exporter Code (IEC) issued aligns with the PAN of the firm. However, the DGFT still issues the IEC separately based on an application. Firms obtaining an IEC may fall under various categories such as Proprietorship, Partnership, LLP, Limited Company, Trust, HUF, or Society.
