The Emoji Only WhatsApp Has: Flags No Other App Will Show
WhatsApp renders flags and redesigned emoji that don't exist anywhere else — including one for Texas. Here's the actual mechanism behind it, and the F1 car and World Cup ball WhatsApp swapped out for sponsors.
Type the right sequence of characters into WhatsApp and a flag shows up that nobody else on Earth can see. Send that same message to an iPhone user on iMessage, or paste it into a Google Doc, and it collapses into a jumble of letters or nothing at all. This isn't a bug. WhatsApp has spent over a decade quietly building a small pile of emoji nobody else supports, plus a habit of redesigning existing emoji whenever a sponsor pays for the pixels.
Unicode allows more flags than any app actually ships
Here's the part almost nobody knows: Unicode's flag system technically supports a flag sequence for practically any region with an ISO 3166-2 subdivision code — that's thousands of possible flags, from Texas to Tasmania. Vendors don't ship all of them. Apple, Google, and everyone else only render the small handful that Unicode formally labels RGI — Recommended for General Interchange. Everything outside that list is valid Unicode that simply renders as plain text almost everywhere.
WhatsApp is the outlier that decided to support flags well beyond that RGI list — some of them years before Unicode caught up, some of them Unicode never caught up on at all. The result: a flag sequence can be completely legitimate Unicode and still only actually look like a flag inside WhatsApp.
England had a flag emoji before Unicode said it could
The England flag showed up on WhatsApp in 2014 — a full three years before Unicode formally standardized subdivision flags in 2017. Scotland and Wales followed in 2016. Then, in late 2017, WhatsApp added a flag for Texas, which has never received RGI status from Unicode and likely never will. Type the Texas flag sequence today and WhatsApp shows a flag; basically every other keyboard shows raw letters or nothing. It's the emoji equivalent of a secret handshake that only works with one specific group of friends.
WhatsApp also holds a genuine firsts record here. The Transgender Flag arrived in WhatsApp version 2.19.62 in March 2019, making it the first platform of any kind to support that flag — before Apple, before Google, before anyone else had shipped it. The Refugee Nation Flag followed in June 2021 and, like Texas, has never picked up RGI status, so it remains WhatsApp-only to this day.
The one WhatsApp added and then quietly deleted
Not every WhatsApp exclusive stuck around. In July 2016, WhatsApp shipped the Olympic Rings as a ZWJ sequence — five interlocking rings built out of Unicode components. About three weeks later, in version 2.16.9, it was gone. No fanfare, no announcement, just a flag-adjacent experiment that didn't survive the month.
Why WhatsApp can do any of this in the first place
From 2009 through 2016, WhatsApp didn't have its own emoji at all — every character rendered using Apple's native designs, on every platform, even Android. That changed in 2017, when WhatsApp built a custom emoji set for Android and web from scratch, one Emojipedia describes as clearly inspired by Apple's style while staying visually distinct. On iPhone, WhatsApp still leans on Apple's own emoji for almost everything. Owning its own font on Android and web is exactly what makes the flag exclusives and the redesigns below possible — there's no vendor gatekeeper standing between WhatsApp and whatever it wants to draw.
When a sponsor pays, the emoji gets a new outfit
WhatsApp has also turned a couple of standard emoji into rolling billboards. In April 2024, the Racing Car emoji got repainted in Mercedes-AMG PETRONAS F1 livery, a redesign that later spread from Android and web to iOS too. Then on June 4, 2026, the Soccer Ball emoji became adidas's official 2026 FIFA World Cup ball, the Trionda — and this one shipped everywhere at once, Android, web, and iPhone, notably overriding Apple's own soccer ball design on iOS. That ball also made an appearance in the World Emoji Day 2026 coverage, where it was one of the year's more talked-about emoji moments.
All of this sits well outside the emoji that Unicode actually standardizes for everyone — the kind covered in the current Emoji 18.0 rundown, where every new character is guaranteed to show up the same way across phones eventually. WhatsApp's flags and brand redesigns don't work like that. They're a reminder that emoji isn't one universal alphabet so much as a loose agreement most apps follow — and WhatsApp has never felt obligated to follow all of it.
