How the Guides Are Checked

  1. Official Sources First

    Each guide is built from the ministry, state or standards body that owns the rules, and links to it.

  2. A Date on Every Guide

    Every guide shows the day it was last verified, so you know how fresh the facts are.

  3. Checked Every Quarter

    Guides are checked again each quarter, and sooner when a country or state changes its rules.
