A new dialling code is to be implemented in the greater Johannesburg area, Telkom said on Tuesday.

The new 010 area code, will not inconvenience customers, Telkom said.

"Telkom has recently been allocated, by ICASA, the first batch of numbers in the 010 area code for use within the same geographic boundary as the existing 011 code," it said.

The company's Group Executive for Network Infrastructure Provisioning Marius Mostert said: "The introduction of the 010 area code has been fuelled by the diminishing capacity of numbers within the 011 area code. We are therefore currently implementing the new code."

He said the introduction of the 010 code effectively doubled the amount of numbers available in the greater Johannesburg geographic area.

"It is important to note that there are sufficient numbers available in other parts of the country and, therefore, there should be no introduction of other second area codes in the foreseeable future," said Mostert.

He added that those who made use of Private Automatic Branch Exchange should contact their service providers, if they experienced any problems.
