Requesting dedicated long codes for SMS messaging with Amazon SNS

A long code (also referred to as a long virtual number, or LVN) is a standard phone number that contains up to 12 digits, depending on the country that it's based in. Long codes are typically meant for low-volume, person-to-person communication. However, you can also use long codes for sending test messages, or for sending low volumes of messages to your customers.

Note

Support for long codes is restricted to the United States only. Sending rates for long codes are restricted to 1 message per second. This restriction is set by the telecom carriers, and isn't a limitation of Amazon SNS. If you send a large volume of messages from a long code, wireless carriers might begin to block your messages. Your applications that use Amazon SNS should limit the number of messages that they send each second.

Note

If you're new to SMS messaging with Amazon SNS, you should also request a monthly SMS spending threshold that meets the expected demands of your SMS use case. By default, your monthly spending threshold is $1.00 (USD). For more information, see Requesting increases to your monthly SMS spending quota for Amazon SNS.
