Two passport rankings can disagree without either table containing a simple arithmetic error. They may count different access categories, compare a different destination universe, use another snapshot date or break ties differently.
The safe comparison keeps the provider, method, metric and date attached to every number.

Quick Answer: Why Do Passport Rankings Disagree?
They do not all count the same thing in the same way.
Providers can differ on passport coverage, destination coverage, visa-free treatment, visa on arrival, ETA or eTA, eVisa, tie-breaking, source inputs and update timing. A rank is meaningful only inside that method and edition.
The Five Methodology Questions
Before quoting a ranking, ask:
- What is the metric? A no-prior-visa score, Mobility Score or another access score?
- Which access categories count? Visa-free, visa on arrival, ETA, eVisa or visitor permits?
- What is the universe? How many passports and destinations are compared?
- How are ties displayed? Shared ranks, skipped positions or a secondary tie-breaker?
- When was it updated? Live data, monthly edition or a dated snapshot?
If an article cannot answer those questions beside the number, the comparison is incomplete.
Henley Passport Index
The Henley methodology page states that the index covers 199 passports and 227 destinations using IATA data supplemented by Henley research.
Under the checked methodology, a passport receives one point when no visa is required or when the traveler can obtain visa on arrival, a visitor permit or an ETA. A traditional pre-departure eVisa is not treated the same way. Equal scores share a rank, and the next lower score receives the next consecutive rank.
Henley describes monthly updates. Its strength is a clearly documented destination universe and consistent no-prior-visa comparison. Its score still does not answer a particular itinerary, transit or stay-purpose question.
Passport Index by Arton Capital
The Passport Index methodology says its Mobility Score includes visa-free entry, visa on arrival, eTA and an eVisa when issued within three days. It states coverage of 199 passports and presents the ranking as live.
For individual ranking ties, the checked method first compares the visa-free share and then uses the 2018 UNDP Human Development Index. That means two passports with the same broad Mobility Score can receive separate individual positions.
This is useful when reading Passport Index on its own terms. It should not be combined with Henley’s destination universe or tie method.
VisaIndex and the Guide Passport Index
The VisaIndex live ranking presents the Guide Passport Index and describes an access total that can include visa-free, visa on arrival, ETA and eVisa access.
WeltFox therefore uses the label provider access score, not “visa-free destinations,” when discussing this method. The public material checked for this guide was not used to infer category totals, a destination universe or a complete tie method.
The passport rankings hub links to the provider’s current table instead of reproducing a full third-party ranking. That table still cannot answer a current trip-specific rule.
How Access Categories Change a Score
Consider a hypothetical destination that changes from a prior visa to an eVisa. A provider that excludes traditional pre-departure eVisas from its positive score may show no increase. A provider that counts a qualifying fast eVisa may add a point. A broader access index may also add it.
The traveler still completes an application before departure in all three descriptions. The ranking difference comes from classification, not from three different border laws.
The access-type guide explains the traveler action behind each label.
How Ties Change the Rank
Suppose three passports have equal scores.
One provider may show all three at rank 5 and the next score at rank 6. Another may show all three at rank 5 and the next at rank 8. A provider with a secondary tie-breaker may order the three separately.
None of those display systems changes the underlying score. It changes what the rank number communicates. That is why score movement and rank movement should be discussed separately.

Henley Passport Index
- Metric
- Destinations accessible without a prior visa under its method.
- Coverage
- 199 passports and 227 destinations.
- Access categories
- Visa-free, visa on arrival and ETA are counted. Traditional pre-departure eVisas are treated differently.
- Ties
- Equal scores share a rank; the next lower score receives the next consecutive rank.
- Timing
- Monthly updates are stated.
- Best use
- A consistent, documented no-prior-visa comparison.
- Main limit
- It is not an itinerary decision.
Passport Index by Arton Capital
- Metric
- Mobility Score.
- Coverage
- 199 passports; no destination total is relied on from the checked about page.
- Access categories
- Visa-free, visa on arrival and eTA are counted. An eVisa is counted when issued within three days under the stated method.
- Ties
- Visa-free share, then the 2018 UNDP HDI for individual tie-breaking.
- Timing
- Presented as a live ranking.
- Best use
- A live category-based mobility comparison.
- Main limit
- Its method is not interchangeable with Henley.
VisaIndex / Guide Passport Index
- Metric
- The provider access score shown on its live ranking.
- Coverage
- Passport and destination totals are not inferred from the checked public methodology material.
- Access categories
- The stated access total includes visa-free, visa on arrival, ETA and eVisa access; no category total is inferred.
- Ties
- A complete public tie method was not relied on here.
- Timing
- The provider publishes a live page; no fixed cadence is assumed.
- Best use
- Read the provider’s current access-score ranking on its own terms.
- Main limit
- The checked public method detail is insufficient for an itinerary decision.
How to Compare Rankings Correctly
- Compare the same provider across two documented dates when discussing movement.
- Compare rank and score separately.
- Keep access category definitions beside the figure.
- Name the destination universe when the provider publishes it.
- Explain the tie method when a headline depends on position.
- Do not mix one provider’s rank with another provider’s score.
- Do not call a combined access score a strict visa-free count.
- Use official travel-document sources for a real journey.
The pre-booking check guide takes over once the question changes from “How do these passports compare?” to “Can this traveler take this route?”

FAQ
Passport Ranking Methodology FAQs
Short answers for comparing index headlines without mixing metrics.
Which passport index is the official world ranking?
There is no single official global passport ranking. Each provider publishes a comparison under its own method. Immigration authorities decide entry rules.
Why can one passport have two access scores?
Providers may count access categories or destinations differently and may use different update dates. Keep each score with its provider and method.
Is an access score the same as visa-free destinations?
Not necessarily. A provider score may include visa on arrival, ETA or eVisa access. Use the metric name published or accurately described for that method.
Can a passport’s rank change without its score changing?
Yes. Other passports can move, or a provider can change tie or display rules. Rank movement and score movement are separate.
Can rankings tell me whether I need a visa?
No. Use the passport, residence status, destination, transit route, purpose and current official sources for that decision.
