How many countries are members of the United Nations?

There are 193 countries that are members of the United Nations. The organisation officially calls them “Member States,” and the total includes every sovereign state admitted under Article 4 of the UN Charter, from Australia and France to smaller states such as Fiji and Iceland.

That figure does not include the two permanent observer states, the Holy See and the State of Palestine. It also does not include territories, dependencies or disputed regions that have international recognition but are not separate UN members. For many general-interest purposes, the answer is therefore simply 193.

Australian readers may encounter the figure in discussions of diplomacy, international law, peacekeeping, trade or travel. Australia was a founding member in 1945, so the United Nations has long been part of the country’s foreign policy and identity as an outward-looking nation.

The current number of UN member states

The UN’s membership register contains 193 Member States. This is the figure used by the General Assembly when calculating voting majorities, and every full member has one vote in that assembly. The total has remained stable for more than a decade, with South Sudan becoming the most recent member in 2011.

The organisation began with 51 members in 1945. Membership expanded as newly independent states joined during the process of decolonisation, while existing states also gained admission. The current count reflects changes in international sovereignty as well as the UN’s willingness to accept new members.

Calling all 193 “countries” is normal in everyday language, although “UN Member States” is the precise term. Some Member States are very large, while others have small populations. Size, wealth or military strength does not determine membership.

How a country joins the United Nations

Article 4 of the UN Charter sets out the admission process. A candidate must be a peace-loving state, accept the obligations contained in the Charter, and be able and willing to meet those responsibilities. The process is designed to confirm that a government genuinely intends to participate in the organisation’s system of international law.

Admission normally begins with a proposal to the Security Council. After the council recommends the application, the General Assembly votes on it. A two-thirds majority of members present and voting is required. Admission therefore involves both a security assessment and broad support from the wider membership.

New members also accept the responsibilities that come with joining, including obligations under international human rights law, peaceful dispute resolution and cooperation with UN institutions. Membership is not simply a symbolic listing on a website; it involves legal and diplomatic commitments.

Member states, observers, and other territories

The Holy See and the State of Palestine hold permanent observer status. They may participate in UN meetings, maintain permanent missions and become parties to certain treaties, but they are not full Member States and do not cast General Assembly votes as members. The Holy See’s observer status should not be confused with separate membership for Vatican City.

Some partially recognised states, including Kosovo, are also absent from the full membership list. Dependencies such as Greenland, Gibraltar and the French overseas territories do not become additional UN members merely because the UN discusses them. Representation can instead come through administering states, special arrangements or political negotiations.

Country lists used for other purposes may also differ. The World Bank, International Monetary Fund, International Olympic Committee and numerous regional bodies maintain their own memberships. An organisation can therefore describe “189 countries,” “193 states” or another total without contradicting the UN’s figure, because each is counting participation in a different institution.

Voting, representation, and the Security Council

Every UN Member State has one vote in the General Assembly, regardless of population or economic output. This equal system allows smaller states to have the same formal voice as larger members. Most General Assembly resolutions are adopted by a simple majority, while important matters such as budget decisions or certain amendments require a two-thirds vote.

Membership also brings participation in the Security Council, the UN’s principal organ for peace and security. The council has 15 members: five permanent members—China, France, Russia, the United Kingdom and the United States—plus ten elected for two-year terms. A permanent member can veto a substantive resolution, although abstention does not amount to a veto.

Australia has held elected Security Council seats and contributed personnel to UN peacekeeping operations. The organisation also operates through courts, agencies, funds and treaty committees whose rules shape issues including refugees, sanctions, human rights and sustainable development. Full membership gives a state a formal role across this wider system.

Australia’s place in the United Nations

Australia was one of the UN’s 51 original members and has participated continuously since 1945. The Department of Foreign Affairs and Trade in Canberra coordinates the country’s diplomatic engagement, while Australia maintains a Permanent Mission to the United Nations in New York and a mission in Geneva. These offices represent Australian positions in debates over security, humanitarian assistance and international law.

International activity is not confined to Canberra. Sydney and Melbourne host consulates, international businesses, media organisations and market institutions that connect Australian organisations with governments and companies across the Member States. Delegations, business delegations and diplomatic missions use those connections to support cooperation on trade, education, health and regional security.

For travellers, UN membership does not determine visa or border requirements. Australians must check destination-country rules and advice from DFAT’s Smart Traveller service, while Australian Border Force administers customs, immigration and biosecurity controls at the border. Membership creates no automatic visa waiver and does not override domestic entry procedures.

International ideas also influence the domestic market, even where they are adapted to local conditions. A feature on Australian kitchen cabinetry trends illustrates how overseas finishes and design approaches are translated for Australian homes, budgets and building requirements rather than copied unchanged.

Why online country totals can differ

The clearest answer is 193, but the wording surrounding a number can change its meaning. Some sites count 195 by adding the Holy See and the State of Palestine, even though they are observers rather than members. Others add territories, separatist states or former colonies. These totals may be useful for their particular purpose, but they are not accurate descriptions of UN membership.

The date of a list also matters. Countries can apply for admission, and institutional membership can change independently of the UN. A travel article, import guide or business report should therefore identify whether it is counting UN Member States, countries eligible for a particular visa, or all recognised states.

The same distinction applies to Australian commercial and administrative information. An airline route map, an Australian Passport destination list, a customs tariff schedule and a UN membership register serve different functions. Their totals can differ because they apply different rules, not because one source has made a simple counting error.

A practical checklist for a reliable country count

When stating the global number of countries in the United Nations, a short verification routine helps prevent confusion between formal membership, observer status and broader geographical lists.

• Lead with the figure of 193 UN Member States.
• Use “Member States” when discussing the organisation’s formal membership.
• Record the date on which the figure was checked.
• Identify observer states separately from full members.
• Check whether a source counts territories, dependencies or partially recognised states.
• Verify visa, customs and trade rules through the relevant government sources rather than inferring them from UN membership.

For general public information, the answer is 193, with the two permanent observer states explained separately when observers are relevant. Different numbers in travel guides, commercial databases or political commentary often reflect a different definition rather than a change in the UN’s official total.

For your next briefing, lead with 193 UN Member States, date the figure and confirm it against the United Nations’ official membership information. Pair that count with current Australian and destination-government guidance whenever it supports decisions about travel, trade, immigration or customs.
