# Buy a number from PolyAI

> Purchase phone numbers directly in Agent Studio.

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.

<Info>
  Managing many numbers? The [Agents API](/api-reference/agents/introduction) exposes bulk [import](/api-reference/agents/endpoint/phone-numbers/import-phone-numbers-into-a-project), [get](/api-reference/agents/endpoint/phone-numbers/batch-get-phone-numbers), and [reassign](/api-reference/agents/endpoint/phone-numbers/reassign-a-phone-number-to-a-different-connector) operations.

## Purchase a number

<Steps>
  <Step title="Open the Numbers page">
    Go to **Configure > Numbers** in the sidebar.
  </Step>

  <Step title="Add a number">
    Click **Add Number**.
  </Step>

  <Step title="Select a region">
    Choose **US** or **UK** depending on where your callers are located.
  </Step>

  <Step title="Confirm">
    Click **Add Number**. The number provisions in seconds and is ready for use.
  </Step>
</Steps>

Once provisioned, you can assign the number to a specific [environment](/environments-and-versions/introduction) (Sandbox, Pre-release, or Live) to control which version of your agent receives calls.

<Tip>Use separate numbers for each environment to avoid accidentally routing test calls to production.</Tip>
