How the groups differ
| Type | Examples | Good for | Watch for |
|---|---|---|---|
| Emoji or pictograph | ⚠ ⚡ ☢ | Status, validation and warning labels | Picking Warning Sign when you wanted Radioactive Sign |
| Symbol | ⟁ | Editing and reference notation | Assuming all 21 behave the same way in every font |
| Punctuation | ¡ ！ | Compact legends and document keys | Copying only part of one of the 3 multi-code-point sequences instead of the whole value |
| Emoji sequence | ❣️ ⚠️ ‼️ | Status, validation and warning labels | Reaching for one of the 18 emoji entries where a text mark was needed, so the colour artwork clashes with the surrounding type |
Warning marks need severity, cause and action
A hazard icon attracts attention but does not tell a reader what happened or what to do. Effective warnings pair the mark with a short, specific instruction.
| Mark | Typical signal | Required context |
|---|---|---|
| ⚠ | General caution | Name the hazard and the safe action. |
| ⛔ / 🛑 | Stop, blocked access or prohibited entry | Explain whether the state is physical, account-based or temporary. |
| ☢ / ☣ | Radiation or biological hazard | Use only for the defined hazard and follow applicable safety standards. |
| ❗ / ‼ | Urgency or emphasis | Do not substitute punctuation for a tested emergency alert system. |
Practical note: Never communicate severity by color or icon alone. Add a heading, plain-language consequence and next step that remain understandable when the symbol is not rendered.

How to use warning symbols
Selecting an entry places its exact code points on your clipboard. Paste with Ctrl V, ⌘ V, or the Paste command on mobile.
01
Status, validation and warning labels
Reach for Warning Sign, and never let it replace a word that matters.
02
Editing and reference notation
For editing and reference notation, choose among the 15 emoji or pictograph entries, then check the weight sits comfortably beside your type.
03
Compact legends and document keys
When creating compact legends and document keys, paste the complete entry — several of these are multi-code-point sequences that break if truncated.

How to type warning symbols on a keyboard
You do not have to copy. Each code point below doubles as a keyboard code — decimal for a Windows alt code, hexadecimal for Word and macOS.
| Character | Name | Windows | Hex | HTML |
|---|---|---|---|---|
| ⚠ | Warning Sign | Alt 9888 | 26A0 | ⚠ |
| ☢ | Radioactive Sign | Alt 9762 | 2622 | ☢ |
| ⛔ | No Entry | Alt 9940 | 26D4 | ⛔ |
| 🚫 | Prohibited | Not available | 1F6AB | 🚫 |
| ❕ | White Exclamation Mark | Alt 10069 | 2755 | ❕ |
| ⁉ | Exclamation Question Mark | Alt 8265 | 2049 | ⁉ |
Alt codes reach only the first 65,536 code points, and only from a numeric keypad. 5 entries here sit above that ceiling. A further 3 are sequences, which no shortcut reproduces — copy those instead. Each platform's method is spelled out in the keyboard guide.
06
How warning symbols render across fonts, apps and devices
Most of these live in one place: Miscellaneous Symbols holds 46% of them. The rest come from Dingbats and General Punctuation. 3 are plain text and follow your font.
The other 18 are emoji, so the system picks their colour, not you. Unicode files the emoji ones under Symbols and Travel & Places. Watch the 3 that use several characters at once.
Copy the whole thing, or it breaks apart. The newest here arrived in Emoji 3.0. Older phones show a blank box instead.
What travels is the character; what you see is whatever font the destination reaches for. That is why the same warning symbol can look heavier on a phone than in a document.

Warning Symbols questions and answers
What is the difference between Warning Sign and Warning?+
U+26A0 is Warning Sign; U+26A0 U+FE0F is Warning. Because the encoded identity differs, substituting one for the other can change what a reader or a piece of software understands.
What is the HTML code for warning sign?+
⚠ is the hexadecimal form and ⚠ the decimal one; both render as ⚠. On a page that declares UTF-8 you can also just paste the character.
Which warning symbols work as plain text rather than emoji?+
Look for the 3 non-emoji entries. Those behave like letters — style them, colour them, put them in a heading. The 18 emoji entries are drawn by the operating system instead.
Why does one of these warning symbols split apart when I paste it?+
3 entries here are sequences of more than one code point. If the destination does not support the sequence, or if the copy was truncated, the parts render individually. Copy the entry with the button rather than by selecting the characters.
Which Unicode block are these warning symbols in?+
Miscellaneous Symbols holds most of them — 6 characters; the rest come from Dingbats and General Punctuation. Older blocks are the safe ones; anything added recently needs testing first.
Will these warning symbols work on older phones?+
The newest entry on this page was introduced in Emoji 3.0. Devices that have not received a font update since then will show a blank rectangle instead. Test on a real older device before using a recent character where the meaning matters.
