195, 197, 249 or 243? What counts as a country in a travel tracker?

Why 193 and 195 both appear

The United Nations has 193 member states. A common 195-country total adds the two UN non-member observer states: the Holy See and the State of Palestine.

That is a useful diplomatic count, but a travel tracker often needs a different model. Travellers also record territories and distinct destinations that are not UN member states.

Where 197 comes from

Many travel lists add Kosovo and Taiwan to the 195 total. That produces 197, but it is a convention rather than a universal official answer. Recognition and political status are complicated, and an app should state its rule instead of presenting the number as settled fact.

Why ISO-style lists are larger

ISO 3166-1 assigns codes to countries, dependencies and other areas of particular geopolitical interest. That makes it useful for software, addresses and datasets, but it answers a broader question than UN membership.

A larger tracker can therefore include places such as Greenland, Puerto Rico, Hong Kong or the Faroe Islands as distinct entries. Whether that is helpful depends on what the product is trying to record.

Noma uses 243 travel places

Noma begins with the country and territory catalog used by the app, then removes seven entries that do not fit its travel-passport model: Antarctica, Bouvet Island, South Georgia and the South Sandwich Islands, Heard Island and McDonald Islands, the British Indian Ocean Territory, the French Southern Territories, and the United States Minor Outlying Islands.

That leaves 243 countries and territories across Africa, North America, South America, Asia, Europe and Oceania. The denominator is a product rule, not a claim that the UN has 243 countries.

A good travel tracker publishes its denominator and exclusions. Otherwise two people can visit the same places and still get different percentages.

Choose a rule you can keep

• Use 193 when you want a strict UN member-state count.
• Use 195 when you also include the two UN observer states.
• Use a declared 197 convention if Kosovo and Taiwan matter to your personal list.
• Use an ISO-based country and territory list when distinct travel destinations matter more than diplomatic status.
• Record the version of the list because names, codes and political realities can change.
