MTNL, Delhi has made available yet another customer friendly feature for all subscribers served from Digital Electronic Exchanges. The facility enables the subscribers to know the telephone number of the calling party. For this, customers have to subscribe to this facility, and have to either use their own FEATURE PHONE (a telephone with in-built facility) or a separate ADD-ON device with the existing telephone instrument. The feature phone and add-on device should have the interface approval of the Telecom Engineering Centre (TEC)

For subscribing to this facility, apply on a plain paper at your Divisional Customer Service Centre only. The charges of this service are Rs. 50/- only per month. In addition, a one time processing fee Rs 50/- only will be charged and billed in your regular bi-monthly bills.

After equipping and subscribing, the called subscribers will get the identification of the calling party, of all the incoming calls, in the format “ABCDEFGHI” followed by Zero. ”ABCDEFGHI” consists of the STD code of the place followed by the local number of the calling party  subscribers.

For example, if a call is made from a number 24364656 of Delhi, the display will show 11243646560. If the call is made from the number 24161234 of Mumbai, the display will appear as 22241612340.

However, if the call is made within the same local exchange, only the seven digit number of the calling party will be displayed.
