Messaging Transfer Confirmation

Messaging Transfer Confirmation (MTC) is a notification service that gives you the ability to approve the transfer of messaging services from your Bandwidth account to another industry provider or another Bandwidth customer. It’s available both via the Bandwidth App and API.

To contract for MTC, please reach out to your Bandwidth Account Manager. Once contracted, the Bandwidth Onboarding Team will add this feature to your account.

Add an MTC subscription

Important Update Regarding Messaging Transfers (Effective June 10, 2026):

  • To prevent unauthorized messaging transfers and protect your numbers, you must contract for MTC and set up a notification subscription.

  • Without MTC contracted, all transfer requests are automatically approved. If MTC is contracted but your notifications are not configured, requests will be automatically denied.

To add an MTC subscription in the Bandwidth App:

  1. Log in to the Bandwidth App.

  2. In the side navigation bar, click Account and select Notifications.

  3. Next to Subscriptions, click Add, and complete the following fields:

    1. Event type: Select Messaging Transfer Confirmation.

    2. Custom name: Enter a name for this subscription (optional).

    3. Delivery type: Select if you want notifications to be delivered via Email or Webhook.

    4. Email: If you selected Email, enter the email address you want notifications to be delivered to.

    5. Frequency: Select if you want to receive notifications Instantly or Daily.

    6. Filter: Click Add filter to add condition(s) (optional).

  4. Click Add subscription.

Locate an MTC request

To locate an MTC request in the Bandwidth App:

  1. In the side navigation bar, select Numbers and click My Numbers.

  2. Search for the number and click it to access its Phone Number Details page.

  3. Locate the transfer confirmation request in the Service activation section (on the Universal Platform) or the Phone number details section (on the Legacy North American Platform) and click Confirm or Deny to complete the process.

Important: If you don’t approve the MTC request within 47 hours, it will be denied. This is done to prevent messaging from being automatically transferred after 48 hours without your explicit approval. Also note, if no subscription is set up, we will not wait the 47 hours and these requests will be denied immediately.

Frequently Asked Questions

Why do messaging transfers have to be approved?

We believe you should have complete control over your numbers. Bandwidth is shifting this choice to our customers so you can decide exactly which messaging port-outs are valid for your business. To give you full decision-making power, you can contract for Messaging Transfer Control (MTC) and set up notifications. If you prefer a hands-off approach, simply leave things as they are, and we will apply a default action on your behalf as outlined above.

What type of numbers does this apply to?

This only applies to long code numbers. The industry doesn’t have the same capabilities yet for toll-free numbers.

What if I’m already hosting messaging elsewhere?

Those numbers will remain where they are. This service only applies to future messaging ports.

Is there an MTC report?

The Messaging Transfer Confirmation Report is located under Number details in the Bandwidth App and provides the following details:

  • TN (telephone number)

  • Customer decision

  • Transfer arbiter (user that made the decision)

  • Transfer decision date

  • Transfer origin (external or internal to Bandwidth)
