If you have ever needed to share an email address, create a username, or write a piece of code while speaking Spanish, knowing how to say underscore in Spanish is more useful than you might expect. The underscore symbol (_) appears constantly in digital communication, yet many English speakers hesitate when they have to pronounce it or explain it in Spanish. But in Spanish, the most widely accepted term for the underscore is guión bajo, though you may also hear regional variations such as raya baja. Understanding which term to use, how to pronounce it, and where it fits in everyday conversation can save you from confusion in professional, academic, and technical settings.
What Is the Underscore Called in Spanish?
The short answer is that the underscore is most commonly called guión bajo in Spanish. Worth adding: this phrase translates literally to "low dash" or "lower dash," which describes both the appearance of the symbol and its position relative to the baseline of written text. You will encounter guión bajo in Spain, Mexico, Argentina, Colombia, and most other Spanish-speaking countries, especially in computing, telecommunications, and office environments.
A less frequent but still valid alternative is raya baja. Think about it: while raya generally means "line" or "stroke," and bajo means "low," this term is heard occasionally in certain Latin American regions. Still, if you are looking for the safest, most universally understood option, guión bajo is the standard choice.
This is where a lot of people lose the thread.
It is also worth noting that the word subrayado exists in Spanish, but it usually refers to the act of underlining text or the state of being underlined, rather than the underscore symbol itself. If you ask a Spanish speaker for the subrayado, they may think you are talking about a highlighted sentence in a document rather than the character _ It's one of those things that adds up..
This is the bit that actually matters in practice.
Guión Bajo vs. Raya Baja: Understanding the Difference
Although both terms refer to the same symbol, they are not always interchangeable in every context. Here is a quick breakdown to help you choose the right one:
- Guión bajo: The dominant term in technical manuals, keyboard layouts, IT support, and everyday digital communication. Use this when dictating an email address, reading a password, or naming a file.
- Raya baja: Understood by most Spanish speakers, but less standardized. You might hear it in casual conversation or in specific regional dialects, but it is rarely the first choice in formal or technical writing.
- Guión medio: This refers to the hyphen (-), not the underscore. Confusing these two is a common mistake, so be careful not to ask for a guión medio when you need an underscore.
If you are unsure which term to use in a particular country, guión bajo will almost always be recognized and accepted.
How to Pronounce "Guión Bajo" Correctly
Pronunciation is often the biggest hurdle for English speakers. The word guión contains an accent mark on the o, which indicates where the stress falls. Here is a simple phonetic guide:
- Guión: gee-ON (the stress is on the second syllable)
- Bajo: BAH-ho (the stress is on the first syllable)
Put together, it sounds like gee-ON BAH-ho. The g in guión is soft, similar to the g in the English word "go," but followed by a u that acts as a bridge to the i. The ñ sound does not appear in guión, but if you ever encounter raya baja, remember that the ñ is pronounced like the "ny" in "canyon Turns out it matters..
Real talk — this step gets skipped all the time.

Typing the Underscore on a Spanish Keyboard
Knowing the word is only half the battle; you also need to know how to produce the symbol. That said, on a standard Spanish keyboard layout, the underscore is usually accessed by pressing the Shift key together with the key that contains the hyphen or dash. This is often located near the right side of the main letter section, though the exact position can vary depending on whether you are using a Latin American or European Spanish layout Most people skip this — try not to..
If you are using an English keyboard but need to type in Spanish, the underscore is typically Shift + hyphen, just as it is in English. The difference lies in what you call it when you read it aloud, not in how you type it It's one of those things that adds up. Less friction, more output..
