Note: Out of the total ATMs deployed by State Bank of India, 156 ATMs are deployed overseas.

1. Number of ATM deployed on site by the bank.
2. Number of ATM deployed off site by the bank.

This was stated by Shri Santosh Kumar Gangwar, Minister of State in the Ministry of Finance in written reply to a question in Rajya Sabha today

Free ATM transaction limits for on bank and out of bank use define customers' entitlement to fee free ATM access. A regulatory notification limits the number of free ATM transactions by distinguishing on us and off us transactions, with lower allowances for off us use in metro areas; the ATM network is described as 100% interoperable and Reserve Bank statistics provide bank wise on site, off site and total ATM deployment figures for Public Sector Banks, culminating in an aggregate total.
