## TL;DR
The European Union is a political and economic union of 27 member countries. Public claims should rely on official EU pages for membership, values, and euro-area facts.

## Core Explanation
The EU combines shared institutions, treaty-based values, and policy coordination among its member countries. Not every EU country uses the euro; the euro area is the subset of EU countries that have adopted the euro as official currency.
