Contact and corrections
One form, two kinds of message. Everything sent here reaches the person who maintains the dataset.
Reporting a data error
The most valuable message we get. Tell us the country or zone, what the page currently says, and what the rule actually is — and, if you can, the instrument, the article number or a URL. A report that names its source can be checked in minutes; one that does not, often cannot be acted on at all.
Everything else
Questions, missing countries, data reuse, press. If you are writing about a specific page, include the link to it.
What happens to a report
A legal correction is checked against the source you cite, or against the primary instrument if you cite none. If it holds, the country record is corrected at source — the map, the country page and the zone pages are all generated from that one record — and the change carries its own citation. If it does not hold, nothing is changed.
Send a message
Include the country or zone, the page you are looking at, and the source if you have one.
