# Purchase 140 & 160-series Numbers

> India-specific DLT-registered number classes

140-series and 160-series numbers are DLT-registered categories required for
commercial voice traffic in India (promotional and transactional, respectively).

<Callout type="warning">
  DLT registration with your telecom provider is required before these numbers can
  be used for outbound calling in India.

Contact your telephony provider (Plivo/Twilio) support to complete DLT registration,
then assign the number to an agent as usual.
