Toll-free numbers - Amazon Simple Notification Service

Toll-free numbers

A toll-free number is a 10-digit number that begins with one of the following area codes: 800, 888, 877, 866, 855, 844, or 833. You can use toll-free numbers to send transactional messages only.

To purchase toll-free numbers, use the Amazon Pinpoint console. No message template registration is required. For more information, see Requesting a number in the Amazon Pinpoint User Guide.

Currently, Amazon Pinpoint supports toll-free numbers for both voice and SMS messages, but Amazon SNS supports SMS messaging only.

Guidelines for using toll-free numbers

When using a toll-free number as an origination number, follow these guidelines:

  • Don't use shortened URLs created from third-party URL shorteners, as these messages are more likely to be filtered as spam.

    If you need to use a shortened URL, consider using a 10DLC number or short code. Using short codes and 10DLCs require that you register your message template, where you can specify a shortened URL.

  • Be aware that keyword opt-out (STOP) and opt-in (UNSTOP) responses are set at the carrier level. You can't modify these keywords or other any other keywords, or the messages that are sent when users reply with STOP and UNSTOP.

  • Don't send the same or similar message contents using multiple toll-free numbers. Carriers call this practice snowshoeing or number pooling and target these messages for filtering.

  • Because toll-free numbers are subject to content filtering, be sure your messages don't contain any of the following types of restricted content:
