NACH (National Automated Clearing House)- Every thing you should know

Recently, following RBI Guidelines, LIC has shifted to NACH (National Automated Clearing House) from ECS (Electronic Clearing Service) for its electronic mode of automatic premium deduction through banks. NACH is a centralised bulk file based transaction processing system, specially designed to facilitate and efficiently manage large volume of collection in retail payment systems.

NACH is facilitated through newly formulated NPCI (National Payment Corporation of India). NPCI is a body formulated by Reserve Bank of India( RBI) in conjunction with  Indian Banks Association and 10 promoter banks.

    The Loan account is in by brother’s name but the ECS debit account is in mine.The first EMI got rejected due to “Payer name mismatch” I contacted the bank that provided the loan and they asked me to submit the ACH mandate form.If I submit it , will it get rejected again due to Payer Name mismatch ?

    Is the Loan account name permitted to be different from the debiting account name ?

    • Anish L J

      Loan account and payer name can be different but only thing is that it should be properly updated in the mandate during the registration process. Name in the NACH and registered in the module must be same. Please submit mandate form after correcting the payer name in the records first.

  • I received a message from the bank from where I took the loan saying – “Nach mandate registration toward loan account has been rejected by Bank due to reason drawers signature differs. The same will be re-loadged with your bank”.

    After one day. I received message saying – “Your security NACH mandate towards loan has been sent for registration. Please request your bank to register the mandate. Mandate will be presented only if the EMI is not paid”

    Not sure what should I do?

    • Anish L J

      The message you received is not from LIC as the account cannot be a loan account and debit is not for EMI in case of NACH policies.
