Starting this Thursday (10th), the mandatory use of the 0303 prefix in calls made to customers by telemarketing companies begins to take effect. The change, announced at the end of last year by the National Telecommunications Agency (Anatel), aims to help users easily identify this type of call and decide whether to accept the call.
The code will appear at the beginning of the number of any call aimed at offering products or services. The changes apply only to mobile phone providers. In 90 days, they should also be implemented by fixed telephony operators.
According to Anatel , the use of code 0303 will be exclusive and mandatory for active telemarketing activities, practice of offering products or services through telephone calls or messages, previously recorded or not. The measure determines that telecommunications networks allow the clear identification of the code on the device’s display.
In addition, operators must preventively block calls originating from active telemarketing at the request of the consumer. The telecoms will also be responsible for employing the necessary technological means to prevent use outside the rules established by Anatel.
