CL Button Emoji

The CL button (🆑) is a digital fossil. It stands for "Clear" — the key that used to sit on calculators and Japanese feature phones to wipe whatever you'd just typed. When NTT DoCoMo's i-mode launched in February 1999 with Shigetaka Kurita's original 176 emoji, the carriers needed a way to reference the physical buttons on their flip phones. CL was one of them. Then the iPhone arrived, physical clear keys disappeared, and the emoji kept existing without its referent. That's why 🆑 is the most confusing squared-word emoji in the family: the object it depicts hasn't existed in most people's lives for 15 years.

Modern readers tend to reinterpret it. "CL" now means different things to different people: Christian Louboutin's CL varsity logo to fashion kids, Craigslist to anyone who used the internet before 2010, Lee Chae-rin of 2NE1) to K-pop fans, UEFA Champions League to European football fans, and "can't lie" or "call" to texters who never thought about it harder than that. 🆑 is a symbol whose original meaning has been buried under layers of coincidental abbreviations. Encoded in Unicode 6.0 (2010) as U+1F191 SQUARED CL.

🆑 is the rarest word button in the family. Outside of emoji explainer content, you'll almost never see it used with its intended "clear / cancel" meaning, because nobody in 2026 has a mental model of a calculator's CLEAR key as common cultural shorthand. When 🆑 does appear in social posts, it's usually doing one of three things. First: ironic retro — deliberate "early-2000s flip phone" aesthetic, often paired with 📟 or 📠. Second: stand-in for a different CL. A Louboutin fan tagging a shoe photo with 🆑👠, a Craigslist reference in a "found it on 🆑" joke, or a CL fan posting about the 2NE1 reunion in July 2024) with 🆑✨. Third: as filler. People who hit 🆑 while browsing the emoji keyboard and send it because the red box looks vaguely official. Google Trends shows "CL emoji" below the floor of every other squared-word button — it's the least-searched member of the family.

🆑 is a souvenir from the Japanese feature phone era. When Japanese carriers — NTT DoCoMo, SoftBank (formerly J-Phone), and KDDI au — were building out their emoji sets in the late 1990s and early 2000s, they needed pictograms for the physical buttons on their handsets. Clear (CL) was one of those buttons: press it to erase the number you'd dialed, the text you'd typed, or cancel a menu selection. The emoji was literal. See a CL button on screen, tap the CL button on your phone. DoCoMo shipped it in 1999, KDDI added it in 2005, and SoftBank added it in 2014 for carrier compatibility. When Unicode absorbed the Japanese carrier sets into Unicode 6.0 in October 2010, 🆑 came along for the ride. The squared Latin letter buttons were included mostly for round-trip conversion with Japanese carrier data — Unicode wasn't judging whether each one was still useful, just making sure no Japanese message would lose characters when translated to the new standard. Then smartphones ate flip phones, physical CL buttons disappeared, and 🆑 became a word without a referent. It sits in the Enclosed Alphanumeric Supplement block quietly, still available, still technically meaning "clear," and almost entirely unused.

Encoded in Unicode 6.0 (2010) as U+1F191 SQUARED CL. Part of the Enclosed Alphanumeric Supplement block (U+1F100–U+1F1FF). Added to Emoji 1.0 in 2015. Originally from Japanese carrier emoji sets: DoCoMo shipped it in January 1999, KDDI in January 2005, SoftBank in January 2014.

• •🆑 is the least-searched emoji in the squared-word family on Google Trends. It gets less search traffic than 🆗, which already sits near zero because "OK" is too common to need searching.
• •The physical CL (CLEAR) button was standard on Japanese feature phones from the i-mode era (1999-2010). When touchscreens replaced hardware keys, the button disappeared — but the emoji stayed.
• •"CL" now means more things than almost any other two-letter abbreviation in English: Christian Louboutin (fashion), Craigslist (classifieds), UEFA Champions League (football), CL the rapper) from 2NE1 (K-pop), "can't lie" (text slang), and chemistry's chlorine. The emoji's original "Clear" meaning barely registers against that crowd.
• •DoCoMo added 🆑 in January 1999, KDDI au in January 2005, and SoftBank in January 2014. The 15-year carrier adoption gap shows how incompatible the early Japanese emoji sets were — SoftBank only added it for Unicode round-trip compatibility after the character was already standardized.
• •The Christian Louboutin CL logo has probably been typed with 🆑 more often than the emoji has been used for its original "Clear" meaning in the last decade. A fashion brand's initials eclipsed the word "clear" in emoji practice.
