AWS pinpoint: Increase registration attachment max file size to 5MB

Service: pinpoint · 2026-09-27 · Documentation low

File: pinpoint/latest/apireference_smsvoicev2/API_CreateRegistrationAttachment.md

Summary

Updated the maximum file size for registration attachments from 500KB to 5MB and renamed the Python SDK label to Boto3.

Security assessment

The change raises an upload size limit (500KB to 5MB) while keeping the same validated file extensions; it is a functional quota change rather than a security fix or hardening guidance.

Evidence

+Create a new registration attachment to use for uploading a file or a URL to a file. The maximum file size is 5MB and valid file extensions are PDF, JPEG and PNG. For example, many sender ID registrations require a signed “letter of authorization” (LOA) to be submitted.
