End User Messaging Registration with Comreg in Ireland stuck as "reviewing"

The "REVIEWING" status for your AWS End User Messaging SMS registration for Ireland/ComReg is taking longer than typical. While there's no specific timeframe mentioned for Ireland registrations, prolonged review periods like yours (three weeks) are not uncommon but do warrant attention.

When a registration is in the "REVIEWING" status, it means your submission has been accepted and is being evaluated, but you cannot make any changes to it during this time. This is a normal part of the process, but three weeks is a considerable wait.

Even without a paid support plan, you can still open a case with the AWS Account team for registration issues. This is specifically available for registration-related problems. When contacting them, be sure to include your registration ID and details about your use case to help expedite the process.

Before reaching out, double-check that you properly completed all the required steps for Ireland registration, including:

• Completing the ComReg Sender ID registration at the ComReg portal
• Selecting "Amazon Web Services" as a third party in Section 2
• Choosing all required OPAs (Sinch Sweden AB, Telesign Corporation, Twilio Inc, and Vonage) in Section 3

Missing any of these steps could cause delays in the approval process. The AWS Support team can help determine if there are any specific issues with your registration that need to be addressed.
