Why this rule existsrationale

Three separate limits apply at once and only the one you hit is reported, so an appeal built from phone photographs of documents fails on total size after being trimmed to ten files. Every attempt costs a cycle, and appeals are usually filed under time pressure with a campaign already blocked.

How to fix itremediation

Combine the pages of each document into one PDF and compress scans to text-readable rather than photographic quality. Two or three well-made PDFs beat ten photographs and land inside every limit at once. Done when there are ten or fewer files, none over 10 MB, and 30 MB in total.

A compliant exampleexample

attachments: cp575.pdf (1.2 MB), state-registration.pdf (0.8 MB) — two documents, all pages in each

Notesnotes

Absorbs OPS-328, which states the same attachment limits alongside the explanation length in BRD-257. Combining pages into one PDF also discharges BRD-260, which requires every page of a multi-page document to be attached.

Rules you will hit next

2 other rules read the appeal attachments. Fixing one field to satisfy a single rule is how a resubmission trades one rejection for another, so read these before you change anything.
