SenderID registration: error when uploading new documents

It seems you're encountering an issue with uploading documents for SenderID registration, specifically related to service quotas. This error suggests that you've reached the maximum number of registration attachments allowed per account.

When registering a Sender ID, some countries require additional documentation to be uploaded. These attachments have specific requirements:

1. The maximum file size for each attachment is 500KB.
2. Valid file extensions are PDF, JPEG, and PNG.

Even if you've deleted a previous registration and created a new one, the quota for attachments is likely account-wide, not per registration. This means that deleting a registration may not reset your attachment quota.

To resolve this issue, you could try the following:

1. Review your account for any unnecessary or outdated attachments and remove them if possible.
2. Ensure that your new documents meet the file size and type requirements.
3. If you've recently deleted attachments, allow some time for the quota to reset.
4. If the problem persists, you may need to contact AWS support to request an increase in your attachment quota or to help resolve any underlying issues with your account's attachment limit.

Remember, clear and concise submissions are essential to avoid rejections and delays in the Sender ID registration process. If you continue to face issues, it's advisable to open a support case with AWS for further assistance.

I understand that you're encountering the following error while trying to upload new company documents:

Error Service Quota Exceeded - Reason="REGISTRATION_ATTACHMENTS_PER_ACCOUNT"

This error occurs because you have reached the maximum limit of 50 "RegistrationAttachments" quota for your account. This is a default service quota set by AWS for Sender ID registration attachments.

To resolve this issue, you can request an increase in the "REGISTRATION_ATTACHMENTS_PER_ACCOUNT" limit by following these steps:

1. Visit the AWS Service Quotas console
2. Submit a quota increase request with the following details:
   • Service: AWS End User Messaging SMS (Pinpoint)
   • Resource Type: Sender ID Registration
   • Region: <REGION>
   • Limit name: Transactional/Notifications/OTP/2FA
   • New limit value: 100
   • Use case description: "Please increase the REGISTRATION_ATTACHMENTS_PER_ACCOUNT limit to 100 in our AWS account."

For detailed instructions on requesting quota increases, please refer to the official AWS documentation: https://docs.aws.amazon.com/sms-voice/latest/userguide/quotas.html#quotas-increase

Please note that the quota increase request will be reviewed by the AWS team, and the processing time may vary.
