HTML Entity for Circled Ring Operator (⊚)
What You'll Learn
How to display the Circled Ring Operator (⊚) in HTML using numeric references, named entities, and CSS escapes. This character is U+229A (CIRCLED RING OPERATOR) in the Mathematical Operators block (U+2200–U+22FF). It represents a circled ring operator used in formal algebra and operator notation.
You can use the named entity ⊚, hex ⊚, decimal ⊚, or CSS \229A. Do not confuse ⊚ with Circled Times U+2297 (⊗, ⊗), Circled Dot Operator U+2299 (⊙, ⊙), or Bullseye U+25CE (◎).

🧠 How It Works
Hexadecimal Code
⊚ uses the Unicode hexadecimal value 229A to display the Circled Ring Operator.
Decimal HTML Code
⊚ uses the decimal Unicode value 8858 to display the same character.
Named HTML Entity
⊚ is the standard named entity for U+229A—short for “operator circle.”
CSS Entity
\229A is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result
All four methods produce the Circled Ring Operator glyph: ⊚. Unicode U+229A sits in Mathematical Operators (U+2200–U+22FF).
Use Cases
The Circled Ring Operator (⊚) commonly appears in:
Equations and formal notation using the circled ring operator.
Ring product, direct product, and operator notation in algebra.
Technical papers and research content with operator symbols.
Math tutorials, textbooks, and e-learning platforms.
Documentation referencing this symbol in formal specifications.
Unicode tables and math operator glossaries.
Use MathML or aria-label="circled ring operator" for screen readers.
💡 Best Practices
Do
- Prefer
⊚for readable math HTML source - Use math-friendly fonts (Cambria Math, STIX Two Math, serif)
- Keep entity style consistent within a document
- Consider MathML for complex equations
- Distinguish U+229A from U+2297 Circled Times in explanatory text
Don’t
- Confuse U+229A (⊚) with U+2297 Circled Times (⊗)
- Put CSS escape
\229Ainside HTML text nodes - Assume every font renders Mathematical Operators identically
- Use ⊚ decoratively where Bullseye ◎ is intended
- Mix entity styles randomly in one file
Key Takeaways
Named entity is the easiest option
