MULTAN, Dec 20: The direct dialling code for Multan district will change from 061 to 61 on Tuesday (today), says a Pakistan Telecommunication (PTCL) press release issued on Monday.

It has added prefix '4' to the old numbers starting from digits 54, 51, 55, 570, 577, 78, 745 and 746, and a prefix of '6' to old numbers starting from digits 52, 24, 536, 539, 77, 750, 752, 760, 762, and 532.

The prefix of '4' would also transform the old numbers of some 23 telephone exchanges into new numbers. They included 18-Kassi, Bosan, Shershah, Bahadurpur, Ayazabad Maral, Lar, Shujabad, Sikandarabad, Basti Malook, Ghazipur, Jalalpur Pirwala, Khan Bela, Zareef Shaheed, Bagreen, Budhla Sant, Gulzarpur, Khokhraan, Qadirpur Raan, Tataypur, Chak 11-MR/Pul-18, Kot Abbas Shaheed, Khanpur Maral and Matotali.
