How passport power is measured
Passport power, or passport strength, is typically measured by the number of countries a passport holder can access without obtaining a visa in advance. The Henley Passport Index, published by Henley and Partners using International Air Transport Association data, is the most widely cited ranking and is updated quarterly.
Access is counted in three tiers:
- Visa-free: no permission required before arrival
- Visa on arrival: permission obtained at the border, still requiring no advance application
- eTA: an electronic pre-authorisation, counted as visa-required by some indices and visa-free by others. The Henley Index counts eTA as visa-free access
That last row is where most of the disagreement between rankings comes from, and it is worth keeping in mind before treating any single number as definitive.
The most powerful passports
The top tier of passport power is occupied by a cluster of Japanese, Singaporean, and Western European passports, each providing access to a very large number of destinations without a prior visa application.
Nordic passports and other EU member states occupy the same tier. The differences between top-ten passports are minor, often a handful of destinations, but the gap between the top tier and mid-tier passports is significant.
Rankings shift quarterly, so check the index directly rather than relying on a figure quoted in an article. Our passport pages show the current corridor-level position for a given passport, which is more useful for planning than a headline rank.
Notable trends over the past five years
The post-Brexit UK passport The UK passport retains its top-tier status despite Brexit. UK citizens lost automatic residency and work rights within the EU, but the Schengen Area remains accessible visa-free for tourism, subject to the 90/180 rule. The practical change for short-stay travellers is modest. For those who want to live or work in EU countries, the change is substantial. See what is Schengen for how the day counting works.
UAE passport rise The UAE passport has risen sharply over the past decade on the back of an active programme of bilateral visa-exemption agreements, one of the more striking trajectories in modern passport history.
US and Canadian passports Both remain strong globally but have seen relative decline as their peer group strengthened. US citizens now require eTAs or visas for some destinations that were visa-free a decade ago.
Indian and Pakistani passports These remain mid-tier despite their countries' economic growth. Visa-free access for holders of these passports remains limited relative to European equivalents, a significant constraint on mobility for hundreds of millions of people.
What drives changes in passport power?
- Bilateral agreements. Most changes come from individual countries negotiating visa-free access with each other, often tied to trade deals or diplomatic relationships.
- Security assessments. Countries add or remove visa requirements based on assessed risk levels, overstay rates, and document fraud statistics.
- Regional blocs. EU expansion extends strong passport rights to new member states. Applicant countries progressively gain access to Schengen visa-free travel as part of the accession process.
- Political shifts. Geopolitical changes can rapidly alter access, and bilateral visa-free agreements have been suspended at short notice more than once in recent years.
Why a headline rank is not a travel plan
A ranking counts destinations. It does not tell you what your specific trip requires, and that is where the friction actually sits.
- A passport ranked highly can still need an electronic authorisation for a destination it counts as 'visa-free'. See what is an eTA.
- Visa-free access says nothing about how long you may stay, or whether repeat visits are limited.
- Transit is assessed separately from entry, and catches out travellers with strong passports regularly. See transit visas explained.
- The corridors that generate the most confusion are not always the ones with the hardest rules. Our look at the most-searched corridors covers why.

Frequently asked questions
What does passport power actually measure?
The number of destinations a passport holder can reach without applying for a visa in advance. It is a count of access, not a measure of how easy any individual trip will be.
Which index should I trust?
The Henley Passport Index is the most widely cited, but indices differ in how they treat electronic authorisations. Compare the methodology before comparing the numbers.
Does an eTA count as visa-free?
It depends on the index. The Henley Index counts it as visa-free access. Others treat it as visa-required, which is why the same passport can appear at different ranks in different tables.
Why do rankings change so often?
The indices update quarterly, and bilateral agreements, security assessments, and political events all shift access between updates.
Does a strong passport mean I can stay as long as I like?
No. Visa-free access is separate from permitted length of stay. Many visa-free arrangements cap stays and some limit how often you may return within a period.
Did Brexit weaken the UK passport?
Not in ranking terms. The UK passport remains top tier for short-stay travel. What changed was the loss of automatic rights to live and work in EU countries, which rankings do not measure.
Why do some passports rank so much lower despite strong economies?
Access is negotiated bilaterally and reflects diplomatic relationships, reciprocity, and assessed risk rather than economic size alone.
Does my passport rank affect transit?
Not directly. Transit permissions are assessed per country and per route, so a highly ranked passport can still require a transit authorisation for a particular connection.
