Sources and methodology
Every number on this site comes from a published dataset. Each source and its licence is listed here, and so is how the data was checked. Where two sources disagree we say which one we used and why. Where we could not settle it, the page says the facts are uncertain.

Plugs and voltage: three sources, checked against each other
Wikidata's electricity statements are known to be patchy. Some name a plug standard family rather than a type: “AC power plugs and sockets: British and related types” could be Type D, G or M. Some list legacy voltages. Many territories have no values at all. So for every one of the 241 places, intl.life compares three sources:
- A: Wikidata (plug type P2853; voltage P2884, with frequency as its P2144 qualifier).
- B: Wikipedia's table “Mains electricity by country” (227 of 241 places).
- C: WorldStandards.eu's country table. We used it only to settle disagreements and do not republish it.
A and B disagreed on plug types for 78 places, on the voltage band (100–127 V or 220–240 V) for 16 and on frequency for 0. A had no plug or voltage data for 7. Differences within the same band, such as 220 V against 230 V, were not counted. Most of Europe and many other countries harmonised to 230 V, and a traveller's device treats the two the same.
Each disagreement got a written resolution. In all, 144 places use a hand-checked value, each recorded with its reason in the table below. The main patterns:
- Legacy socket types. B often lists types that survive only in old buildings or on special circuits, such as D and M in the UK, Hong Kong and Singapore. We publish them as “also found” and mark the type to plan for as the main type, which drives the adapter advice.
- Ambiguous Wikidata items. These were resolved to letters using B and C.
- Old voltages. A sometimes keeps a voltage the country has since replaced, such as 127 V in Morocco, Indonesia and Libya. We publish the current one.
- Genuinely mixed places. In Guyana, Suriname and Liberia the sources disagree because the supply is mixed. The pages say so and tell readers to check each socket, rather than picking a side.
- Missing from B. Territories with no row in B take C's values, or those of the country whose grid supplies them, and are marked as less certain.
Validation: 25 countries in detail
The 25 countries travellers ask about most, with each source's raw values and the published result. Plug letters in A shown after “+” were ambiguous items mapped to candidates.

Will my plug fit? The compatibility rules
The fit chart on the plug types page and every adapter verdict use one table of which plug fits which socket. It was written by hand from the standards described in Wikipedia's “AC power plugs and sockets”. “Fits with a caveat” covers three cases. A plug may fit without its earth connecting, such as French and German plugs in Danish sockets. Only some plugs of a type may fit: only the hybrid E/F plug fits both French and German sockets. Or the fit may be physically possible but unsafe, such as a Europlug in an Indian Type D socket. For the adapter verdict, a traveller's plugs are their home country's main types. A plug counts as fitting only if it fits one of the destination's main socket types without a caveat.
The voltage verdict compares the two countries' bands: 100–127 V against 220–240 V. A move from low to high is flagged as a risk to single-voltage devices, high to low as underpowering, and any place that uses both bands as “varies”.
Price level
The World Bank has archived its ready-made price level ratio, so we compute it the same way. We take the purchasing-power parity conversion factor for household final consumption (PA.NUS.PRVT.PP, local currency per international dollar) and divide it by the official exchange rate (PA.NUS.FCRF, local currency per US dollar) for the same, most recent year. Then we multiply by 100, so the United States is 100. It measures what a household basket costs, not hotel or restaurant prices, and places with no recent data show none.
Check: these 12 orderings are well established in published ICP results. The computed values agree with 12 of 12.

Other notes
- Currencies are the ones CLDR lists as legal tender today, so Bulgaria shows the euro, adopted on 1 January 2026, and Zimbabwe shows the ZiG and the US dollar. Wikidata's currency statements were not used: they still contain retired currencies such as the Polish złoty's pre-1995 code.
- Languages are those CLDR marks as official, de facto official or official in a region, with its estimate of the share of people who speak each.
- Time: offsets and daylight-saving status come from tzdata at build time; clocks on the pages run in your browser. A country's “main” time zone is the one nearest its capital.
- Holidays are national public holidays only. Islamic and other lunar-calendar dates are estimates and may move by a day when the moon is sighted. Ukraine shows none because it suspended public holidays as days off under martial law.
- Advisories: territories without their own advisory show their parent country's and say so. The US feed sometimes has two items for one country; we prefer the newer link format.
- Which places are included: every place with an ISO 3166-1 code and at least 1,000 inhabitants, plus Vatican City and Kosovo. Uninhabited and military-only territories are left out.
- Flags are the files Wikidata links to. Oman's flag and emblem are under a licence (“OGL-om”) whose terms for commercial reuse we could not confirm, so they are not shown.
