🆄 Negative Squared Latin Capital Letter U

What 🆄 means

🆄 itself has no fixed U-specific instruction: read a lone one as a decorative U, and let surrounding text define any local label. The wider boxed-symbol family had reached Japanese mobile-phone emoji by 1999. It gathered compact phone labels and broadcast marks rather than starting as one universal alphabet.

ARIB STD-B24, Japan’s digital-broadcast character standard, supplied other service and wayfinding signs; that connection was documented in 2007. By 2010, boxed A, B, O, and AB marked blood types, while P marked parking. As of 2026, no U-specific meaning annotation is recorded for this character.

Niche and neutral: it reads like a decorative letter or label, not a standard emotional cue.

For a blood-type mark, use , , , or ; 🆄 is not the blood-type U.

Questions people ask

2

Is 🆄 an emoji?

No. It is a font-drawn text symbol, not a standardized emoji character; its dark-square glyph may still look like one.

Why does 🆄 show as an empty square?

The active or fallback font may lack its glyph, so the software substitutes a missing-character box. The text still contains 🆄.
