What is 160-series numbers?
160-series numbers are the number range TRAI assigns to businesses for service and transactional calls, so customers can recognise a legitimate company call.
Examples of service calls are order updates, appointment reminders, EMI due notices and account information sent to existing customers.
Using the right series matters: customers are used to ignoring unknown mobile numbers, and regulators expect commercial calls to come from designated series.
At Vyora: Vyora's standard outbound calls run on TRAI-compliant 160-series numbers.
