Domains

1. Visit the Console and sign in.

2. Navigate to Twilio Admin > Domains.

3. Click the Add Domain button.

4. On the Verify Domain page, enter your company's domain name then click the Save & continue button.

5. Select either the DNS or HTTPS method to verify the domain:

   • If you select DNS: Update your domain's DNS configuration and add a new TXT resource record with the host set to _twilio. The Verify Domain Twilio Admin page will present a text string containing a unique token to use as the body of the record. You will need to visit your domain registrar to add this string to your DNS record.
   • If you select HTML: Upload an HTML page file to your website's root directory. To use this option, your site must be accessible via HTTPS. When you select this option, the Verify Domain Twilio Admin page presents a Download HTML File button — click this to get the file you will upload to your own site. The file contains the same token used for the DNS record option.

6. Click the Verify Domain button.

7. Upload your HTML file or update your DNS records.

Twilio checks your DNS record or uploaded file immediately, but because DNS records can take up to 72 hours to propagate — usually it's much quicker than that — you may not see your domain marked as verified straight away if you have used this method.

In any case, Twilio re-checks the file upload or DNS data every 24 hours to confirm your continued ownership. If the token gets altered or removed, an Organization's Owner or Administrator has 30 days to re-validate the domain before it is automatically deleted from the Organization. Until the domain is re-validated, you will not be able to use email addresses from that domain to add new users.

If a domain is left unvalidated for more than 30 days, any managed users previously added to the organization will automatically be removed. You will have to add the managed users back to the Organization after validating the domain.

1. Visit the Console and sign in.
2. Navigate to Twilio Admin > Domains.
3. Click the Delete Domain button under the Actions column for the domain you want to delete.

In some situations, companies might want to keep different business units as separate Twilio organizations. To enable these units to access organization-level functionalities, Twilio allows the same internet domain to be verified by more than one Twilio organization — this is called the multi-verified domain.

Organizations with a multi-verified domain are able to:

1. Verify the same domain in more than one organization, up to a limit of 20 organizations with the same domain.
2. Manage users and respective accounts independently in each Twilio organization without dependencies from other organizations with the same domain.
3. Enforce single sign-on for their specific set of users.

Organizations with multi-verified domain aren't able to:

1. Apply the organization settings using the option to get new users to auto-join or join through invitation-only.
2. Bulk import users automatically without invitation.

A user or account can only be managed by a single organization at a time.

When one organization verifies the domain that was previously verified by another organization, all organizations will be notified and the functionalities above will be disabled. If you want to verify your company's internet domain in more than one organization, please talk to support.

See the Import Users feature description for instructions on how to bulk import existing Twilio users from your verified domain into your Organization.
