Flag: U.S. Outlying Islands Emoji

The flag assigned to the United States Minor Outlying Islands, a scatter of nine specks in the Pacific and Caribbean that the US controls but nobody really lives on. Because the islands have no flag of their own, every platform renders 🇺🇲 as the Stars and Stripes. Visually identical to 🇺🇸. Semantically a very different thing.

The group covers eight Pacific insular areas (Baker, Howland, Jarvis, Johnston, Kingman Reef, Midway, Palmyra, and Wake) plus Navassa Island in the Caribbean between Haiti and Jamaica. Most were grabbed under the 1856 Guano Islands Act, which let American citizens claim any uninhabited, unclaimed guano-rich island for the United States. The guano is long gone. The islands stayed.

There are no permanent residents. Midway has a rotating crew of around 40 US Fish and Wildlife Service staff and contractors. Wake has a small Air Force caretaker contingent. The rest are visited only by occasional scientists, wildlife officers, and US Navy patrols. Seven of the Pacific islands sit inside the Pacific Remote Islands Marine National Monument, which at 490,343 square miles is one of the largest marine protected areas on Earth.

This emoji exists because ISO 3166-1 assigned the group the code UMUM, and Unicode mechanically generates a flag sequence for every ISO code. Almost nobody types 🇺🇲 on purpose. When it does appear, it's usually in geography trivia, vexillology threads, WWII history, or discussions of the Pacific Remote Islands monument.

Virtually zero mainstream social usage. If you search for 🇺🇲 on TikTok or Instagram, you mostly find geography-trivia accounts and the occasional flag-quiz video where it appears as the answer to 'which flag emoji is identical to the US flag but isn't the US flag.'

Where it does show up:

- Geography and flag-nerd content on TikTok, YouTube, and r/vexillology. 'Flag emojis you didn't know existed' clips reliably cite 🇺🇲 alongside 🇨🇵 Clipperton, 🇧🇻 Bouvet, and 🇭🇲 Heard & McDonald. - WWII history accounts posting about the Battle of Midway anniversary (June 4-7) or Amelia Earhart's Howland Island flight. - Wildlife and conservation posts about the Laysan albatross colony on Midway, the Pacific Remote Islands Marine National Monument, or the ongoing plastic pollution crisis on Midway's beaches. - Ham radio DXpedition threads. Several of these islands are among the rarest amateur-radio contacts on Earth. - Unicode and i18n developer threads discussing flag emojis that render as other countries' flags.

There is no diaspora. Nobody is from here. That's what makes the emoji unique: it represents territory without people.

The Minor Outlying Islands are a legal and administrative bucket more than a place. They were grouped together in 1986 as a single ISO 3166-1 entry (UMUM) to make geographic data easier to classify. Before that, each island had its own status and administrative history.

Most were claimed under the Guano Islands Act of 1856, which let any American citizen claim an uninhabited, unclaimed island rich in seabird droppings for the United States. Guano was the 19th century's premier fertilizer, and US ships combed the Pacific for deposits. Congress stapled a citizenship-length sovereignty clause to the act, and dozens of tiny dots on the map became American.

Midway Atoll was claimed in 1867 and eventually became the site of the Battle of Midway in June 1942, the turning point of the Pacific war. US code-breakers figured out that 'AF' in Japanese communications was Midway, the Navy ambushed the Japanese carriers, and four fleet carriers were sunk over three days. Japan never recovered its offensive initiative. The atoll still has the old runway and a small memorial.

Howland Island is the 2.6-square-kilometer dot that Amelia Earhart never reached. On July 2, 1937, she and navigator Fred Noonan radioed in low on fuel, couldn't see the island, and vanished. The US Coast Guard cutter Itasca was waiting at Howland to guide them in. The 16-day search involved nine ships, 4,000 crew, and 66 aircraft at a cost of over $4 million, and found nothing. A small lighthouse on Howland still honors her.

Palmyra Atoll is the outlier that isn't entirely uninhabited: it's privately owned by the Nature Conservancy and hosts a handful of researchers. It's also where, in August 1974, a pair of drifters named Buck Walker and Stephanie Stearns murdered a vacationing San Diego couple and stole their yacht. The case became *And the Sea Will Tell*, a Vincent Bugliosi true-crime bestseller.

Wake Island, west of Hawaii, hosted a 16-day Marine and civilian defense against a Japanese invasion in December 1941 that became a propaganda cornerstone. It's still an active Air Force airfield.

Inside the United States, 🇺🇲 is almost unknown as a distinct emoji. Americans who stumble on it assume it's a duplicate of 🇺🇸 or a rendering bug. Even most US passport holders who've been to Hawaii have never set foot on or thought much about the Minor Outlying Islands.

Among the tiny communities who do care, the mental model splits hard:

- Pacific war historians treat 🇺🇲 as shorthand for Midway and Wake, loaded with June-anniversary content. - Ornithologists and conservationists see it as the Laysan albatross atoll where every chick necropsy turns up lighters, bottle caps, and toothbrush fragments from across the Pacific rim. - Ham radio operators rank Midway, Palmyra, and especially Wake high on the DXCC most-wanted list and plan years-long expeditions around them. - Legal geeks know the Guano Islands Act of 1856 as the weirdest piece of 19th-century American land law still technically on the books.

For everyone else, the flag is a curiosity: a Stars and Stripes that isn't quite the Stars and Stripes.

• •All nine islands together cover about 34 km² of land. The marine monument around them covers 1,269,982 km², roughly 37,000 times larger than the land they surround.
• •Kingman Reef has essentially no dry land. At low tide it's a sliver of coral you could walk across in 30 seconds.
• •Wake Island is in the next day from California: it sits just west of the International Date Line. When it's Monday morning in Los Angeles, it's already Tuesday on Wake.
• •Midway had a thriving 1950s commercial airport, used as a refueling stop on trans-Pacific flights before jets made the hop non-stop. The old terminal still stands.
• •Navassa Island, the lone Caribbean member, is still disputed by Haiti, which claims it under an 1801 constitutional provision. The US claim comes from, yes, the Guano Islands Act.

• •🇺🇲 is the regional indicator sequence U+1F1FAU+1F1FA (U) + U+1F1F2U+1F1F2 (M). The territory code UMUM comes from ISO 3166-1.
• •On every major platform, 🇺🇲 renders identically to 🇺🇸 (United States). They are different codepoint sequences but produce the same glyph.
• •If your app displays flag names or tooltips, surface 'U.S. Outlying Islands' rather than 'United States' to avoid conflating the two.
• •For analytics or regional filtering, treat 🇺🇲 as a distinct code: ISO UM has its own UN M.49 geographic classification (581) separate from US (840).
