The department of telecommunications allocates from time to time new set of MSC codes to operators in certain circles where the operators meet certain qualifying criteria of subscriber base.
DOT has assigned new MSC codes to Bharti Airtel for crossing 1 million new subscriber additions in Odisha, Karnataka and Tamil Nadu circles.
The details of the MSC codes assigned are given below:
| Name of operator | Name of circle | MSC codes allotted |
| Bharti Airtel | Odisha | 73258-73260, 73268-73270, 73278-73280, 73288 |

The above allocation also includes MSC codes which were previously allotted to other licensees and are hereby withdrawn with immediate effect as the said licences had been quashed by the Supreme court in 2012.
