New Delhi: Telecom regulator Trai on Tuesday said a corporate number can be ported out only if it is signed by the authorised person of the subscriber to whom that number has been allotted.
"No corporate mobile number shall be ported unless the porting request in respect of such number is accompanied by an authorisation issued by the authorised signatory of the subscriber to whom such number has been allotted," Trai said while releasing Telecommunications Mobile Number Portability (Fifth Amendment)Regulations, 2013.
A corporate mobile number is allotted by operators in the name of a firm or organisation.
The Telecom Regulatory Authority of India (Trai) said a corporate number user may make porting request for more than one number provided that a separate unique porting code be generated and the user should pay separate charge for each number.
"Every access provider shall prefix the character 'C' to the unique porting code generated for porting of corporate mobile number," Trai said.
The regulatory said every operator on receipt of porting request, forward within 24 hours, the corporate number and its unique code and scanned copy of the authorisation letter to the mobile number portability service provider.
"Every donor operator shall reject a request for porting of a corporate mobile number if the same is not accompanied by an authorisation letter from the authorised signatory of the subscriber," Trai said.
