Any procedure to check no of bank accounts of a pvt ltd

1. Ask for Bank Statements  and Go through them

    Try to Spot out Transactions having Reference No. as "00000" 

     You will definately get Account no. against such rerence/ chq no.

     Ask the Management to furnish the detail of the party concerned

2. While checking the vouchers, focus on the Account no. from which the payment is being made.

3. Also check those payments which have been adjusted into the books of Accounts by way of Journal Entries

Dear Mr. Khanna...
