Purchase a phone number from Retell directly in the dashboard or through the API. Retell manages these numbers, so you don’t have to set up any telephony infrastructure.
Currently we only support purchase of US and Canada numbers and support making calls to 15 countries. If you are looking to use numbers from other countries, or to make calls to more countries, or to use your own telephony provider, check out Custom Telephony guide.

From the dashboard

You can purchase a number and bind agents to it from the dashboard. You can optionally specify the area codes you want to purchase from. After purchasing, you can change the number’s nickname to make it easier to find and identify. The number is ready to accept inbound calls once you’ve assigned an inbound agent. Try calling it.

From the API

Check out Create Phone Number API Reference for all the parameters you can use programmatically.
  • Phone numbers are yours once purchased, and can be used indefinitely. Find numbers you own here.
  • You can assign different inbound and outbound agents to the number.
  • If you don’t want a user to be able to call this number (maybe you are doing outbound calls and don’t want callbacks), you can leave inbound_agent_id unset.

Pricing

We support both Twilio and Telnyx numbers:
  • Twilio
    • US numbers: $2/month
    • US toll-free numbers: $5/month
    • Canadian numbers: $2/month
  • Telnyx
    • US numbers only: $2/month
Toll-free numbers cost $0.06 per minute for inbound calls. Outbound calls are charged at the same rate as regular U.S. numbers.
The monthly number fee is billed to your payment method at the end of each billing cycle (prorated if purchased mid-month on credit-based accounts) and recurs until the number is released. See the billing overview for how number charges appear on your invoice.

FAQ

Yes. Connect your own telephony provider through custom telephony, or import an existing number into Retell.
Not directly. Retell-managed numbers are US and Canada only. To use numbers from other countries, connect your own provider via custom telephony. Retell-managed numbers can still place calls to 15 countries.
Delete it from the phone number page in the dashboard, or call the Delete Phone Number API. The monthly fee stops once the number is released.
