AWS End User Messaging Toll Free Number registration

I thought you may try below:

1. Mock the Opt-In Flow Even if you're only receiving SMS from service providers, you can create a mockup that shows:

• A portal or internal system where your team enters the toll-free number
• A statement like: “By providing this number to service providers, you consent to receive SMS verification codes” This satisfies the requirement for a clear opt-in workflow, even if it's internal.

2. Use AWS End User Messaging APIs You can automate the registration using AWS APIs:

• create-registration
• describe-registration-field-definitions
• create-registration-attachment (for opt-in mockup)

3. Consider 10DLC Instead If toll-free registration continues to stall, 10DLC (10-digit long code) might be a viable alternative:

• Slightly lower throughput
• Requires brand and campaign registration
• May be better suited for receiving verification codes

I understand the challenges you're facing, and here's some clarification and guidance.

First, it's important to note that the registration requirements, including the opt-in workflow, are part of compliance regulations set by the telecom carriers themselves, not by AWS. We're required to collect this information to meet these industry-wide standards.

For your unique use case of receiving verification codes from service providers, you can still complete the registration process. Here's how:

1. In the Use Case Category, select "One-time passwords".

2. In the Use Case Details, explain that the number will be used exclusively for receiving verification codes from service providers, not for sending messages to customers. Describe how your company provides this number to service providers for 2FA purposes.

3. For the Opt-in Workflow Description, explain that the "opt-in" occurs when your company explicitly provides the toll-free number to service providers for verification purposes.

4. For the Opt-in Workflow Image, you could provide a screenshot or diagram showing how you set up this number with your service providers for receiving verification codes. Or a flowchart showing the flow from the service provider sending a code to the company receiving it.

Regarding Amazon Pinpoint, while it's transitioning to legacy status, it's important to understand that AWS End User Messaging is the underlying primitive service that powers SMS capabilities for all AWS services, including Pinpoint, Connect, Amazon SNS, etc. Moving forward, AWS End User Messaging will continue to provide robust SMS capabilities.

And for Originators: 10DLCs have a much higher throughput, and TFNs the lowest. (Sender IDs are not available in the US.)

I hope this helps.
