Paytm Postpaid service is a pre-approved and instant credit facility for common customers of Paytm and ICICI Bank. The loan will be given by ICICI Bank to Paytm customers and the eligibility will be decided based on your transaction history with Paytm. At present, the credit limit being offered to users is between Rs 500 and Rs 6,000. It will be necessary to link the ICICI savings bank account while setting up the Paytm Postpaid account. Paytm will generate a transaction statement on the first of every month. The default repayment option is auto-debit from your ICICI Bank account.
