Bring Your Own Carrier lets you use phone numbers you already own in your Twilio account as caller IDs for your agents. You are never billed here for those numbers. Calls run through your Twilio account, on your Twilio bill.

​
What you need

  • A Twilio account with at least one voice number.
  • Your Twilio Account SID.
  • A Twilio API key set to the Standard key type, and its Secret.

​
Step 1. Get your Twilio credentials

1

Copy your Account SID

Sign in to the Twilio Console. Your Account SID is the value that starts with AC, shown under Account Info on the Console home page. You can also copy it from the Console URL when it is visible there. If you use subaccounts, make sure it is the same account where you create the API key below.
2

Create a Standard API key

Go to Account, then API keys & tokens, then Create API key. Give it a name you will recognise, set the Key type to Standard, and click Create.
3

Save the SID and Secret

Twilio shows the API Key SID (it starts with SK) and the Secret. Copy both now. The Secret is shown only once, so save it before you leave the page.
Prefer not to make an API key? You can use your Account SID and Auth token instead. An API key is the safer choice, since you can revoke it later without rotating your account.

​
Step 2. Connect Twilio in the app

1

Open the connect dialog

Go to Phone Numbers, then click Connect your Twilio account.
2

Enter your credentials

Paste your Account SID, then the API Key SID and Secret. Leave Use auth token off unless you chose the auth token route above.
3

Connect

Click Connect. We check the credentials with Twilio before saving anything.

​
Step 3. Import a number

1

Open the import dialog

Click Import a number from Twilio.
2

Pick a campaign and a number

Choose the campaign the number should call from, then pick one of your Twilio voice numbers.
3

Import

Click Import. There is no charge and no monthly fee. The number stays in your Twilio account and is ready to make and take calls right away.

​
Good to know

  • We never buy or release your numbers. They stay yours.
  • Removing a number here restores its previous Twilio voice settings and leaves it in your account.
  • Your imported numbers work for both outbound and inbound calls.
