Supported Providers

The phone number integration modal offers three ways to connect a number. Availability depends on your account configuration.

ProviderHow it works

Telnyx (bring your own)Paste your Telnyx API key and account public key, plus the E.164 number you own on Telnyx.

Searching for a Telnyx Number

If your account is set up with Telnyx as its telephony provider, Get a number searches the Telnyx pool. You can narrow the results by:

  • Country — United States or Canada
  • City
  • State or province
  • Area code

Searches run server-side, so your browser never handles a provider credential.

Bringing Your Own Telnyx Account

  1. Select Telnyx from the provider list.
  2. Paste your Telnyx API key. It’s treated as a password and is not shown back to you.
  3. Paste your account public key — in the Telnyx portal, under Account Settings > Keys & Credentials.
  4. Enter the phone number you own on Telnyx, in E.164 format (for example +15551234567).

Atlas validates the key, provisions the call-control application and outbound voice profile in your Telnyx account on first use, and links the number to your campaign.
