EAS Validate

This tool validates an EAS file against the 2025 to 2026 validation rules that can be checked in your browser.

Some rules need reference data that is not in the file. These are shown as manual checks with summaries to help you review them.

The EAS file is processed in your browser, and is not transmitted elsewhere.
