Every rule in the database is linked to a source. A rule is marked as verified only when an official source confirms it: a foreign ministry, border authority, embassy or the official legal text.
Blogs, media and guides are used only to find out what needs checking. Such rules are marked as based on a secondary source.
So that any nationality and any country can be checked, the basic “passport → country” answer for all 199 countries comes from the open Passport Index dataset. It is labelled as a secondary source with its data date. Where we have a rule built from an official source, that rule is shown instead.
Every basic answer is cross-checked against a second source — reference tables compiled from IATA Timatic data (the system airlines check) for 196 nationalities. When the sources agree, we say so. When they disagree, the more cautious answer is shown along with both versions — confirm those on the country's official website.
Every answer links to the destination's official government site and, when a visa or travel authorisation is needed, to the official application portal. We never link to commercial intermediaries.
Every rule has a check date. Rules older than 90 days and rules with an end date are re-checked first.
Rule changes are published in the “Rule changes” section only with a link to a source.
