Confusing O and 0 in codes, usernames, or serial keys is a common headache—slashed zero fixes it instantly. Use this FontSt’s Slashed 0 Font Generator tool to generate 0̸ / 0̷ / 0̶ and copy & paste clear slashed-zero numbers anywhere you type.
If you’ve ever mixed up O (the letter) and 0 (the number) in a code, username, or ID, you’re not alone. A slashed 0 makes the zero instantly recognizable—perfect for passwords, serial keys, and tech-style text. This page shows what a slashed zero is, how to copy & paste it, and where to enable it in fonts and apps.
A slashed 0 font is a typeface (or text style) where the digit 0 is drawn with a diagonal slash so it won’t be confused with the letter O. You’ll see it in developer fonts, terminals, UI dashboards, serial keys, and anywhere clarity matters.
Important note:
A true slashed zero is the number 0 with a slash.
The character Ø / ø is a slashed O used as a letter in some languages, not the number zero (even though it looks similar).
You can paste 0̸ / 0̷ / 0̶ directly into Notes, Messages, IG bio, etc.
If it looks misaligned, switch between 0̸ and 0̷ (different apps render overlays differently).
Android
Most Android keyboards won’t type it directly, but copy/paste works fine.
Some apps might display a slightly different slash thickness depending on font rendering.
If you’re using it inside a stylish bio and want it to match your aesthetic text, you can generate a clean overall style first in the Font Styles directory, then replace only the zeros: Font Style Name List
Slashed Zero Font In Word
In Microsoft Word, you have two common ways:
Use a font that supports slashed zero
Many developer/monospace fonts include it
Some fonts let you toggle it via OpenType features (varies by font and Word version)
Use copy/paste overlays
Paste 0̸ or 0̷ directly into your document
This is the fastest method if you’re sharing a document and just need clarity
For documents where readability is critical, consider a “code-friendly” look (monospace + clear digits). If your FontSt library includes a monospace set, prioritize that style for codes and IDs.
If the user is searching “slashed zero font free download,” they usually want a real font file where zero is slashed by design, typically for:
coding and terminals
spreadsheets and dashboards
product keys and serial numbers
printed labels
For FontSt pages, you can position this clearly:
FontSt provides copy & paste slashed zero symbols
For a “true font download,” users should choose a licensed font that includes slashed zero support
A helpful way to guide readers is to point them toward “fonts with slashed zero” lists (below), then remind them they can still use 0̸/0̷/0̶ when they can’t install fonts.
If you plan to publish “copy & paste” styles for numbers beyond slashed zero (like circled numbers, outlined digits, etc.), it fits nicely under a numbers-style section in your FontSt directory.
Is Ø the same as a slashed zero? No. Ø/ø is typically a letter (slashed O) in certain alphabets. A slashed zero is the digit 0 drawn with a slash. For copy/paste clarity, use 0̸ / 0̷ / 0̶.
Which is best: 0̸ or 0̷? It depends on the app. 0̸ is usually compact and clean, while 0̷ can look more obvious in some fonts. Try both and pick the one that aligns best on your target platform.
Can I use slashed zero in Instagram usernames? Often no—usernames can be strict and may reject combining marks. If it doesn’t work in the username field, use it in the display name or bio instead.
Why does the slash look off-center sometimes? Because these are overlay marks and each platform renders them differently. If alignment matters (like in a document or code editor), use a real font that has slashed zero built into the glyph.
Will slashed zero help with passwords and serial keys? Yes—this is one of the main reasons people use it. It reduces confusion when sharing codes via screenshots, chat, or printed text.
How do I remove slashed zero and return to normal 0? Just replace 0̸/0̷/0̶ with a standard 0 (or retype the number). Overlay characters are not a toggle—they’re different Unicode sequences.
