The Mexican peso symbol is the dollar sign ($), the same character used for the US dollar. The peso has no separate Unicode symbol of its own, so it borrows the dollar sign at code point U+0024, whose official Unicode name is DOLLAR SIGN.
To keep it apart from other dollars, it is often written MX$ or Mex$, and its ISO 4217 currency code is MXN. Copy it below.
Because the peso shares one plain ASCII character with the dollar, there is nothing exotic to install and no special font needed. Any keyboard, app, or website that can type $ can type the Mexican peso sign, and the MX$ form is just those two letters placed in front of it.
Mexican peso symbol codes
Every code below belongs to the dollar sign, since that is the character the peso uses. The columns are labelled so you can tell the hex code point apart from the decimal Alt code and never confuse the two.

How to type the Mexican peso symbol
On nearly every device the sign is already on the keyboard, so the fastest route is a single keystroke. If you would rather skip codes entirely, grab it from our copy-paste symbols tool and paste it where you need it.
Windows
Hold Shift and press 4 on a US or UK layout. On some European layouts it is AltGr+4, or a dedicated $ key. If your layout hides it, turn on Num Lock and press Alt+36 on the numeric keypad; 36 sits below 127, so there is no leading-zero version to worry about here.
With no keypad, open the emoji panel with Win+. and search “dollar,” or copy it from Character Map.
Mac
Press Shift+4. Mac has no Alt codes, so there is no numeric sequence to memorise for this one. If you prefer a menu, open the Character Viewer with Control+Command+Space and search “dollar sign,” then double-click to insert.
Microsoft Word
Type it straight from the keyboard with Shift+4. To build it from the code instead, type 24 and press Alt+X, which turns 24 into $.
Insert → Symbol → More Symbols lists it too. The Alt+X trick works in Word, Outlook, and OneNote, but not in Excel, PowerPoint, or Google Docs, so do not carry it into those apps.
Excel and PowerPoint
In both, Shift+4 types the sign. One catch in Excel: the $ also marks absolute cell references, like $A$1, so inside a formula it behaves as an operator rather than text.
To place the character itself in a cell, type it as ordinary text or use =UNICHAR(36). PowerPoint takes it straight from the keyboard with no fuss.
Google Docs and Sheets
In Docs, Shift+4 works, or use Insert → Special characters and search “dollar.” Google Sheets has no Insert Symbol menu at all, so type $ from the keyboard or use =UNICHAR(36). If you are pasting into a cell, press F2 first to enter edit mode.
iPhone and Android
Tap the “123” key to switch to numbers and symbols, then tap $. On many keyboards you can long-press $ to reveal other currency signs like ¢, €, £, ¥, and ₩, though the peso itself is the plain dollar sign you already see. To type MX$ or Mex$ in one tap, add a text replacement in your keyboard settings.
Chromebook
ChromeOS has no Alt codes, and plugging in a USB numpad will not add them. The $ lives on the keyboard at Shift+4. If you need it from a code, press Ctrl+Shift+U, type 24, then press Enter; an underlined u appears while you type to confirm the input mode.
Notion, Slack, Discord, and Canva
All four take the $ straight from the keyboard, so there is no special peso shortcut to learn in any of them. Just type it, or paste it. If you write MX$ often, set up a text replacement (or a Slack text expansion) so a short trigger expands to it automatically.
Where the peso symbol is used
You will see $ on Mexican price tags, receipts, invoices, and online store listings. In spreadsheets and accounting it prefixes amounts the same way it does for the dollar. The MX$ or Mex$ form shows up in international pricing, travel booking sites, and currency tables, where writing a bare $ next to US prices would leave readers guessing which dollar you mean.
Why the peso uses the dollar sign
The $ sign is usually traced to the Spanish-American peso, and it was in use before it ever meant “US dollar.” Both currencies descend from the same silver coin, so they ended up sharing the mark. Unicode never added a peso-specific character, so Mexico still writes prices with the ordinary dollar sign, and the ISO code MXN carries the “this is a peso” information whenever the plain $ would be ambiguous.
Symbols people confuse with the peso sign
Because it is simply a dollar sign, the peso is most often confused with the US, Canadian, and Australian dollars and other currencies that share the glyph. It sits closest to the Brazilian real symbol (R$), which pairs a letter with the very same dollar sign to mark a distinct currency.
Frequently asked questions
Is the Mexican peso symbol the same as the US dollar sign?
Yes. Both use $ (U+0024, DOLLAR SIGN), the identical character. When the context could be unclear, the peso is written MX$ or Mex$, and its three-letter ISO code is MXN, while the US dollar is USD.
Does the Mexican peso have its own Unicode symbol?
No. Currencies like the euro (€) and pound (£) have dedicated code points, but the peso does not. It reuses the ordinary dollar sign at U+0024, so any keyboard, font, or app that can type $ can type the peso sign without extra setup.
What does MX$ mean and when should I use it?
MX$ (or Mex$) is the dollar sign with a country prefix that marks the amount as Mexican pesos rather than US or other dollars. Use it on price lists, invoices, and travel pages read by an international audience. In banking and accounting, the ISO code MXN does the same job.
Can I use the peso sign in a username or bio?
Yes. $ is a standard ASCII character supported everywhere, so it works in social bios, display names, and usernames wherever a platform allows symbols. MX$ works too, since it is only letters and a dollar sign.
How do I make MX$ type automatically?
Set a text replacement. On iPhone: Settings → General → Keyboard → Text Replacement. On Mac: System Settings → Keyboard → Text Replacements.
In Word: File → Options → Proofing → AutoCorrect. Pick a trigger such as “mxp” that expands to MX$.
