Toll-free numbers
A toll-free number (TFN) 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 TFNs to send transactional messages only.
Important
US mobile carriers have recently changed their regulations and require all toll-free numbers (TFNs) to complete a registration process with a regulatory body before September 30, 2022. Check the status of your TFN by going to Toll-free number registration status. For more information about registering your company see Registering your toll-free number.
It can take up to 15 business days for your registration to be processed after it is submitted.
Update March 3, 2023: Effective April 1, 2023, mobile carriers will apply the following industry-wide thresholds for messaging sent over any unregistered toll-free number:
-
Daily limit: 500 messages, resets at 12:00 AM PT
-
Weekly limit: 1,000 messages, resets Sunday at 12:00 AM PT
-
Monthly limit: 2,000 messages, resets at the end of calendar month at 12:00 AM PT
Update September 19, 2022: Effective October 1, 2022, mobile carriers will apply the following industry-wide thresholds for messaging sent over any unregistered toll-free number:
-
Daily limit: 2,000 messages
-
Weekly limit: 12,000 messages
-
Monthly limit: 25,000 messages
We strongly encourage you to complete your registration as soon as possible. Messages sent via unregistered TFNs will be on a best effort basis. The messages will be subject to increased filtering and blocking over time as carriers continue to restrict unregistered traffic.

Guidelines for using toll-free numbers
TFNs are typically used only within the US for transactional messaging, such as registration confirmation or for sending one-time passwords. They can be used for both voice messaging and SMS. Average throughput is three message parts per second (MPS). However, this throughput is affected by character encoding. For more information about how character encoding affects message parts, see SMS character limits in Amazon SNS. For more information about registering a TFN, see Toll-free number registration requirements and process.
Each customer account can have up to five TFNs. If you're sending over 15 text messages per second but less than 100, we recommend that you register one or more 10DLC origination IDs. If your use cases require sending more than 100 text messages per second, we recommend that you purchase and register one or more short codes.
When using a TFN 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 keywords 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. You also can't modify messages that are sent when users reply with STOP and UNSTOP.
-
Don't send the same or similar message contents using multiple TFNs. Carriers call this practice snowshoeing or number pooling and target these messages for filtering.
-
Any messages related to the following industries may be considered restricted and are subject heavy filtering or outright blocks. This can include one time passwords (OTP) and multi factor authentication (MFA) for services related to restricted categories.
If you had a registration denied for being a non-compliant use case and you feel this designation is incorrect, you can submit a request via support. For details on how to do this, see Registration issues.

Purchase a toll-free number
To purchase TFNs, use the Amazon Pinpoint console at https://console.aws.amazon.com/pinpoint/

Toll-free number registration requirements and process
Important
A TFN can be revoked if it is used for any purpose other then its specified use case.
Toll-free number forbidden use cases
Amazon SNS has limited ability to send messages in cases where the messages are blocked (for example, use cases related to controlled substance, or phishing), or when high levels of filtering are expected (for example, high risk financial messages). You may be unable to register TFNs associated with restricted content use cases defined in Guidelines for using toll-free numbers.
