What is 140-series numbers?
140-series numbers are the range TRAI designates for promotional telemarketing calls.
Promotional calls market a product or service to people with no existing relationship, so they carry stricter requirements, including honouring the DND registry and calling-hour limits.
If you only call existing customers about their orders, appointments or accounts, you are generally in the service category instead.
Common questions
- Can I use a normal mobile number for outbound business calls?
- Commercial calling is expected to use designated telemarketing series. Check TRAI's current rules or ask your provider.
