You can purchase a phone number directly from PolyAI without needing a third-party telephony provider like Twilio. PolyAI-provisioned numbers are preconfigured to route calls to your agent immediately.
Managing many numbers? The Agents API exposes bulk import, get, and reassign operations.

​
Purchase a number

1

Open the Numbers page

Go to Voice > Numbers in the sidebar.
2

Add a number

Click Add Number.
3

Select a region

Choose US, UK, or Canada depending on where your callers are located.
4

[Optional] Pick an area code

For US and Canada numbers, you can optionally specify a 3-digit area code to source the number from a specific region (for example, 415 for San Francisco or 416 for Toronto). Leave the field empty to let PolyAI auto-assign one from the available pool.Both countries share the North American Numbering Plan (NANP), so area code selection works identically.
5

Confirm

Click Add Number. The number provisions in seconds and is ready for use.
Once provisioned, you can assign the number to a specific environment (Staging or Live) to control which version of your agent receives calls. Sandbox has no phone numbers, so test there over an in-app call instead.
Use separate numbers for each environment to avoid accidentally routing test calls to Live.
