Twilio phone number configurations are also Region-specific.
This guide will show you how to create and manage these Region-specific Twilio resources using the Console.
Phone numbers themselves are global resources. Your account has a single pool of numbers, and these numbers may be used with any Twilio Region. However, each of your phone numbers can have a distinct configuration in each Region.
For example, you may have a phone number that is configured with a Voice URL of
https://us.example.com/twilio in the US1 Region, and is configured with a Voice URL of
https://aus.example.com/twilio in the AU1 Region. The configuration that is ultimately used depends on which Region incoming calls are processed in. See our guide to incoming call routing to learn more about this.
To manage your phone number configuration for a specific Region, first ensure that you have the Phone Numbers product pinned in that Region. Then, navigate to the Active Numbers link under Phone Numbers product menu within the relevant Region section in the navigation menu:
Finally, click on the phone number that you wish to manage.
The first time you manage a phone number in a new Region, you may see a banner near the top of the configuration page that says "No Configuration." If this occurs, simply enter a friendly name or a webhook URL for the number in this Region, and click the Save button at the bottom of the page to create a configuration.
Your account's Auth Token and API Keys are Region-specific.
To view and manage these, click the Account menu in the top right-hand corner of the Console, and select "API keys and tokens". After entering your verification code to access the page, select a Region using the menu near the upper right-hand corner of the page.
