How can I block or allow outbound SMS messages to a specific list of countries?

Plivo uses Geo-Permissions to help curb unexpected costs and protect your account from potential misuse by restricting SMS traffic to specific countries based on your business needs.

You can choose to enable or disable SMS traffic to additional countries as needed. Messages sent to countries that are not enabled in your Geo-Permissions will be blocked and will fail with error code 450. These blocked messages are not charged.

To manage your account's SMS Geo-Permissions:

  1. Log in to your Plivo console.
  2. Navigate to the Messaging section.
  3. Go to the Fraud Shield subsection.
  4. Select the account or sub-account you wish to configure.
  5. Under Manage Geo Permissions and Messages Per Hour Fraud Thresholds, you can enable or disable countries as needed. Use the search bar or apply filters such as risk level or continent to easily find and select the countries you want to enable or disable.

Note:

  1. You can set custom Geo-Permission preferences at the sub-account level, allowing for more granular control over different segments of your business.
  2. Any changes you make to Geo-Permissions are immediately enforced for new messages sent via the SMS API or for messages that are queued in Plivo's system.
  3. Effective February 1, 2025, messages to disabled countries will fail with HTTP status code 403 instead of error code 450.
