PGA e SANCHIT LPCO uploads require ICEGATE registration to link IRNs to customs entries for paperless clearance. PGAs will upload digitally signed Licences, Permits, Certificates and Other Authorizations on e SANCHIT and generate a unique Image Reference Number (IRN) for each LPCO; beneficiaries must register on ICEGATE to enable linkage of the IRN to their IEC/GSTN and email, and must tag the IRN to the Bill of Entry or Shipping Bill so customs officers can view the LPCO as a supporting document. Amended LPCOs require reupload with a new IRN and corresponding amendment of the BE/SB; untagged IRNs may be linked by beneficiaries through a Service Centre amendment.
