UN M49 Regions Explained: The Codes Behind UN Statistics

By Pascal · Published 8 November 2026 · 7 min read

What M49 is

M49 is the United Nations Statistics Division's list of Standard Country or Area Codes for Statistical Use. It was first published in 1970 as "Series M, No. 49", which is where the name comes from. It does two jobs:

It gives every country or area a 3-digit numeric code, such as 404 for Kenya or 840 for the United States.
It groups those countries or areas into geographic regions, each with its own 3-digit code, so that UN agencies can publish comparable totals for "Western Africa" or "South America".

The list covers 248 countries or areas, not just the 193 UN member states. Territories such as Greenland, Réunion and Puerto Rico have their own entries, because statistics are collected for them separately.

UNSD is explicit that the grouping is a statistical tool, not a political statement. Its M49 page says the assignment of countries or areas to groupings "is for statistical convenience and does not imply any assumption regarding political or other affiliation of countries or territories".

The hierarchy: regions, sub-regions, intermediate regions

M49 has four geographic levels below the World (001):

5 regions: Africa 002, Americas 019, Asia 142, Europe 150 and Oceania 009.
17 sub-regions: two in Africa, two in the Americas, five in Asia, four in Europe and four in Oceania.
8 intermediate regions, used only where a sub-region is very large: the four parts of Sub-Saharan Africa, the three parts of Latin America and the Caribbean, and the Channel Islands within Northern Europe.
Countries or areas, each with its own code.

Antarctica (010) sits directly under the World and belongs to no region.

Tree diagram of the M49 standard: World 001 splits into Africa 002, Americas 019, Asia 142, Europe 150 and Oceania 009, then into 17 sub-regions, with Sub-Saharan Africa and Latin America and the Caribbean split further into intermediate regions — Diagram: the M49 tree with each group's code and number of countries or areas (source: UN Statistics Division; counts from Wikipedia's UN M49 article).

Region	Sub-region (code)	Intermediate regions (code)	Countries or areas
Africa 002	Northern Africa 015	none	7
Africa 002	Sub-Saharan Africa 202	Eastern 014, Middle 017, Southern 018, Western 011	53
Americas 019	Latin America and the Caribbean 419	Caribbean 029, Central America 013, South America 005	52
Americas 019	Northern America 021	none	5
Asia 142	Central 143, Eastern 030, South-eastern 035, Southern 034, Western 145	none	50
Europe 150	Eastern 151, Northern 154, Southern 039, Western 155	Channel Islands 830 (in Northern Europe)	51
Oceania 009	Australia and New Zealand 053, Melanesia 054, Micronesia 057, Polynesia 061	none	29

Two codes are easy to mix up. Western Europe is 155 (France, Germany, the Benelux countries, Austria, Switzerland, Liechtenstein and Monaco), and Southern Europe is 039 (Italy, Spain, Portugal, Greece, the western Balkans, Malta and the microstates). The code 152 is not a region at all: it is Chile's country code.

Worked example: tracing Kenya up the tree

Kenya's M49 code is 404. Reading upward:

404 Kenya belongs to the intermediate region 014 Eastern Africa (22 countries or areas).
Eastern Africa is part of the sub-region 202 Sub-Saharan Africa (53).
Sub-Saharan Africa is part of the region 002 Africa (60).
Africa is part of 001 World (248).

Kenya is therefore 1 of 22 entries in Eastern Africa, or 4.5%, and Eastern Africa holds 22 of Africa's 60 entries, 36.7%. Only 18 of those 22 are sovereign countries with hoyoopin pages; the other four are Mayotte, Réunion, the French Southern Territories and the British Indian Ocean Territory. Using the UN estimates for 1 July 2023 shown on hoyoopin, the 18 countries had 486,666,433 people, 32.9% of the 1,478,994,605 living in hoyoopin's 54 African countries, and Kenya's 55,339,003 people were 11.4% of that Eastern African total. A UN table of "Eastern Africa" also counts the four territories, so its total will be slightly higher.

Edge cases that surprise people

Because M49 is drawn for statistics, a few placements differ from what school atlases or politics might suggest.

Country or area	M49 placement	Why it surprises
Russia `643`	Eastern Europe 151	The whole country, including Siberia, counts as Europe
Turkey `792`, Cyprus `196`	Western Asia 145	Cyprus is an EU member; Turkey spans both continents
Georgia, Armenia, Azerbaijan	Western Asia 145	All three are Council of Europe members
Mexico `484`	Central America 013	Not in Northern America, which holds only Bermuda, Canada, Greenland, Saint Pierre and Miquelon, and the US
Greenland `304`	Northern America 021	Part of the Kingdom of Denmark, which is in Northern Europe
Antarctica `010`	No region	The only entry outside all five regions

Two places that have their own hoyoopin pages, Kosovo and Taiwan, do not appear in the M49 list at all. The State of Palestine does appear in M49 (Western Asia) but is not one of hoyoopin's 196 countries.

Codes shared with ISO 3166

The M49 country codes are older than ISO's numeric codes. UNSD released them from 1970, and the second edition of ISO 3166-1 adopted them in 1981 as its numeric codes. That is why Kenya is 404 in both systems, and why the numeric code is the safest key for matching a country to UN data. The ISO country codes guide explains the letter codes that go with it.

The region codes are M49-only. ISO 3166 has no regions, so a code like 155 will never appear as a country. One practical tip for anyone handling either set: M49 codes always have three digits, with leading zeros, as in 039 for Southern Europe or 004 for Afghanistan. Store them as text rather than numbers, or a spreadsheet will quietly turn 039 into 39 and break every lookup.

Other M49 groupings

Next to the geographic tree, M49 keeps three lists used in development statistics: Least Developed Countries (199), Landlocked Developing Countries (432) and Small Island Developing States (722). The old split into "developed" and "developing" regions, introduced in 1996, was removed in December 2021.

How hoyoopin's six continents compare

hoyoopin does not use M49 regions, and its country pages do not show an M49 region or sub-region. It sorts its 196 countries into six continents: Africa, Asia, Europe, North America, South America and Oceania. M49 has five regions, because it treats the Americas as one region.

hoyoopin continent	Countries on hoyoopin	M49 equivalent	M49 countries or areas
Africa	54	Africa 002	60
Asia	48	Asia 142 (plus Taiwan)	50
Europe	45	Europe 150 (plus Kosovo)	51
North America	23	Northern America 021 + Central America 013 + Caribbean 029	41
South America	12	South America 005	16
Oceania	14	Oceania 009	29

Apart from splitting the Americas, hoyoopin's continents follow the same lines as M49: Russia is listed under Europe, while Turkey, Cyprus and the three South Caucasus countries are under Asia. Mexico, Central America and the 13 Caribbean nations are in North America. The gaps in the counts are territories, which M49 lists and hoyoopin does not; the guide to territories and dependencies covers them.

Key takeaways

M49 is the UN Statistics Division's code list: 248 countries or areas, 5 regions, 17 sub-regions and 8 intermediate regions.
Western Europe is 155 and Southern Europe is 039.
The groupings are for statistical convenience and carry no political meaning.
M49 country codes are the same as ISO 3166-1 numeric codes.
hoyoopin uses six continents and no M49 regions; the only structural difference is that it splits the Americas into North and South America.

Frequently asked questions

How many regions and sub-regions does the UN M49 standard have?

Five regions (Africa, Americas, Asia, Europe, Oceania) and 17 sub-regions. Eight intermediate regions add detail inside Sub-Saharan Africa, Latin America and the Caribbean, and Northern Europe (the Channel Islands). Antarctica sits outside every region.

What are the M49 codes for Western and Southern Europe?

Western Europe is 155 and Southern Europe is 039. Eastern Europe is 151 and Northern Europe is 154. The code 152 is not a region; it is Chile's country code.

Are M49 country codes the same as ISO 3166 numeric codes?

Yes. The UN Statistics Division published the 3-digit country codes from 1970, and ISO 3166-1 adopted them as its numeric codes in its 1981 second edition. Kenya, for example, is 404 in both.

Does hoyoopin use the UN M49 regions?

No. hoyoopin groups its 196 countries into six continents and does not show M49 regions. Its continents follow the M49 regions except that the Americas are split into North America (including Central America and the Caribbean) and South America.
