Request an SMS-enabled phone number through Amazon Pinpoint SMS

Important

Some countries require phone numbers and sender IDs to be registered for use in the country. It can take up to 15 business days to process a registration request after it is submitted. We strongly recommend you begin this process early. For more information about registering, see Registrations.

Using Amazon Pinpoint SMS, you can request new SMS-enabled phone numbers or reuse existing SMS-enabled phone numbers for use in Amazon Connect. You can request short codes, 10-digit long codes (10DLC), and toll-free numbers. These are also known as Origination Identities (OIDs).

For instructions about procuring a number for SMS messaging, see Requesting a phone number in the Amazon Pinpoint SMS User Guide.

Best practices for requesting SMS numbers

  • Each type of OID has a different registration process and the leasing costs vary. Review the pricing here: Amazon Pinpoint SMS pricing.

  • When deciding what type of phone number to request, we recommend considering your throughput needs. SMS messages are delivered in 140-byte sections known as message parts. Your throughput rate is the number of message parts that you can send each second.

    • 1–3 message parts per second: Use a toll-free number. We recommend using a 10DLC number or short code if your throughput needs will exceed these limits as you expand your use cases. These number types provide plenty of room for growth, but also cost more and currently take longer to obtain than a toll-free number. For more information about requesting a toll-free number in Amazon Pinpoint, see Requesting a phone number.

    • 10–75 message parts per second: Use a 10DLC number. You can also use a short code, which would provide additional room for growth, but would also cost more. For more information, see Requesting dedicated long codes for SMS messaging with Amazon Pinpoint SMS.

    • 100 message parts per second or more: Use a short code. When you create your request in the AWS Support Center Console, specify the throughput rate that you want your short code to support.

      By default US short codes support 100 message parts per second, but the throughput rate can be increased beyond that rate for an additional monthly fee. For more information, see Requesting short codes for SMS messaging with Amazon Pinpoint SMS.

  • Request at least one of the above OIDs as a TRANSACTIONAL number from Amazon Pinpoint.

  • Be sure to provide all of the information requested during the registration process. There are no exceptions to the questions being asked.

    Important

    Providing incomplete or inaccurate information will increase the registration time. Your registration will need to be edited and returned to be reviewed again.

    Registration for all types of OIDs in the US are managed by a third-party registrar. Amazon does not review applications.

  • Toll-free phone number registration requires the least amount of time to procure.

  • Review the 10DLC registration process explained in the Amazon Pinpoint SMS User Guide.
