How we verify what we publish
Travel rules published wrongly can cost you a fine or an entry ban, so this page describes exactly how our information is produced — including its limits.
Source policy
Every rule, date, fee or threshold on this site must be checked against a primary official source before publication:
- EU law as published on EUR-Lex / the Official Journal (regulations, Council decisions)
- European Commission and other EU institution pages (europa.eu)
- National government authorities
Blogs, news articles and other travel sites are never used as the basis of a value — at most they help us locate the primary source. Where two official pages disagree, the legally controlling text (the regulation) wins; we record the conflict. This has already caught real discrepancies — an official EU information page still displaying the superseded €7 ETIAS fee after Delegated Regulation (EU) 2025/1411 set it to €20.
Structured, dated, cited
Rules live in structured data files, each carrying the legal source, a per-claim citation list, and the date it was last checked. Pages display "Checked against official sources" with that date. If we can't reach a primary source for a fact, we don't publish the fact — you may occasionally see a gap where other sites confidently state a number; that's deliberate.
Automated freshness checks
The official pages we rely on are monitored weekly for content changes. When a watched source changes, the affected values are re-checked and their "checked" dates updated.
Verification is automated — here's what that means
Checks against official sources are performed with AI assistance and recorded per claim; there is no separate human editorial review. That's why every value links its source: you can — and for high-stakes decisions should — verify the original yourself. The calculator additionally reproduces the European Commission's own worked examples in an automated test suite, and its results always link the official EU calculator for cross-checking.
Found an error?
The fastest way to get it fixed is to point us at the official source that contradicts us. Errors are corrected with priority over everything else.
