Flag: United Nations Emoji

The flag of the United Nations, a light-blue field with a white UN emblem at center: a polar azimuthal projection of the world map encircled by two crossed olive branches. The projection is deliberately flattened so no country sits at the "top," and the olive branches echo a symbol of peace going back to ancient Greek and biblical traditions.

🇺🇳 is one of only two supranational flag emojis in the Unicode set (alongside 🇪🇺). It isn't tied to a nation-state. It shows up in diplomatic posts, peacekeeping and humanitarian content, Model UN student accounts, UN agency social feeds (UNICEF, UNHCR, WHO, UNESCO, UN Women, WFP), and in global-solidarity moments. Climate COP summits, UN General Assembly week, International Women's Day, World Refugee Day, and Human Rights Day are the flag's biggest recurring windows.

The flag was adopted on October 20, 1947 by the UN General Assembly, two years after the organisation was founded in San Francisco on October 24, 1945. The original emblem was sketched during the 1945 San Francisco Conference by a team led by American architect and graphic designer Donal McLaughlin, who headed the graphics design unit of the US delegation. The color, known as "UN Blue," was picked to contrast with red, the color of most wartime flags, and to signal peace and calm.

The emoji is a regional indicator sequence: U+1F1FA REGIONAL INDICATOR SYMBOL LETTER UU+1F1FA REGIONAL INDICATOR SYMBOL LETTER U + U+1F1F3 REGIONAL INDICATOR SYMBOL LETTER NU+1F1F3 REGIONAL INDICATOR SYMBOL LETTER N. "UN" isn't a standard ISO 3166-1 country code, but it's an exceptionally reserved code set aside for the United Nations at the UN's request. Unicode added 🇺🇳 in Emoji 4.0 (November 2016), much later than most country flags, because the special reservation had to be recognised before platforms could render it.

🇺🇳 mostly shows up in institutional and policy contexts. It's not a flag most people post about themselves; it's a flag they post about things happening in the world.

UN agency accounts lead. @UN, @UNICEF, @UNHCRefugees, @WHO, @UN_Women, @UNESCO, @WFP, and @UNDP are the highest-volume 🇺🇳 posters on X. Each agency has its own voice, but the flag threads through headers, bios, and campaign imagery.

UN General Assembly week. September's UNGA high-level week (the last full week of September in New York) is the flag's biggest annual spike. Member state leaders arrive in Manhattan, every head of government gets a speaking slot, and the resulting 🇺🇳 pile-on covers diplomatic quote tweets, national-flag pairings, and agency announcements.

Climate COPs. The annual UN climate conference (COP28 in Dubai, COP29 in Baku, COP30 in Belém in November 2025) drives a multi-week 🇺🇳 spike every autumn. Activist accounts, NGO coverage, and press posts all lean on the flag.

Peacekeeping and humanitarian field accounts. UN peacekeeping missions (MINUSCA in the Central African Republic, MONUSCO drawing down in the DRC, UNIFIL in Lebanon) and field teams post 🇺🇳 in operational updates. The flag is a field identity marker, not just a branding choice.

Model UN and education. High-school and university Model UN clubs use 🇺🇳 heavily on Instagram and TikTok. Conference recap posts, committee shots, and "best delegate" announcements are a consistent subculture.

International observances. The UN observance calendar schedules dozens of international days. World Refugee Day (June 20), International Women's Day (March 8), World Food Day (October 16), Human Rights Day (December 10), and World Health Day (April 7) are the biggest flag windows.

  UN Day: October 24, anniversary of the Charter's entry into force

The UN's flag grew out of its own founding conference. At the San Francisco Conference in April to June 1945, the US delegation's Office of Strategic Services set up a graphics unit led by Donal McLaughlin. The unit designed conference badges, credentials, and press materials. McLaughlin's team sketched the first version of the azimuthal-projection-with-olive-branches emblem as a delegate lapel pin. It was never meant to be a flag. The pin's design migrated onto the conference's official documents and stuck.

The United Nations was formally founded on October 24, 1945, when the Charter came into force with enough ratifications. The emblem McLaughlin's unit had drawn was adopted on December 7, 1946 as the official UN seal. The flag itself was adopted two years later, on October 20, 1947, by General Assembly Resolution 167 (II).

Why this shade of blue? The color was chosen specifically to contrast with the red that dominated wartime flags. UN Blue was meant to read as peace, sky, and calm. The exact shade has drifted slightly over the decades, but the current reference is approximately #5B92E5#5B92E5. The olive branches come from the ancient Greek tradition of crowning victors and envoys with olive wreaths, and from the Genesis 8 account of the dove returning to Noah's ark with an olive leaf. It reads as peace across most major cultural traditions.

Why the polar projection? The emblem maps the world using an azimuthal equidistant projection centered on the North Pole, with the circle of latitude extending roughly to about 60° south. The design was deliberate: by flattening the world into a circle centered on the pole, no continent gets placed "above" or "below" another. It also meant the original 1945 projection didn't need to place Antarctica on any specific side, avoiding the political fights of a Mercator.

Expansions. The emblem has been revised quietly a few times. Most notably in the late 1980s, the map was adjusted slightly to include a larger southern band as new member states joined. The flag's proportions are 2:3.

• •The UN emblem was sketched as a conference lapel pin, not as a flag. It only became the official seal in December 1946 and the flag in October 1947.
• •The map on the UN flag uses an azimuthal equidistant projection centered on the North Pole, deliberately placing no country at the "top" of the world.
• •The UN has 193 member states. The most recent addition was South Sudan in July 2011. Palestine and the Holy See are permanent observer states.
• •There are six official UN languages: Arabic, Chinese, English, French, Russian, and Spanish. Documents and meetings use all six with simultaneous interpretation.
• •The UN Headquarters in New York sits on land donated by John D. Rockefeller Jr. in 1946. The 18-acre site is international territory.
• •The emoji 🇺🇳 was added to Unicode in Emoji 4.0 (November 2016), roughly a year after most country flag emojis were added. The delay was because the UN's "UN" ISO reservation had to be recognised as a valid regional indicator pair.
