Numbers in Spanish 1 to 1,000: The Complete Guide With Pronunciation

Getting your Trinity Audio player ready...

Spanish numbers are easier to learn than they first seem. Once you know the numbers 1–15 and the main tens, most numbers follow a simple pattern. However, the tricky parts are the small grammar rules, such as when to use uno, un, or una, and how numbers like 16–19 are formed. 

In this guide, you’ll learn Spanish numbers from 1 to 1,000, with pronunciation tips, grammar explanations, and real examples for everyday situations. For more practical vocabulary, check out our Spanish greetings guide.

Spanish Numbers 1–15 (The Core Group to Memorise)

The first 15 numbers are the most important to memorise because they form the foundation for almost every other number in Spanish. Unlike larger numbers, many of these don’t follow a predictable pattern, so learning them by heart will make counting much easier.

Number	Spanish	Pronunciation
1	uno / una	OO-noh / OO-nah
2	dos	dohs
3	tres	trehs
4	cuatro	KWAH-troh
5	cinco	THEEN-koh (Spain) / SEEN-koh (Latin America)
6	seis	sayss
7	siete	see-EH-teh
8	ocho	OH-choh
9	nueve	NWAY-veh
10	diez	dee-ETH (Spain) / dee-ESS (Latin America)
11	once	ON-seh
12	doce	DOH-theh (Spain) / DOH-seh (Latin America)
13	trece	TRAY-theh (Spain) / TRAY-seh (Latin America)
14	catorce	kah-TOR-theh (Spain) / kah-TOR-seh (Latin America)
15	quince	KEEN-theh (Spain) / KEEN-seh (Latin America)

Tip: In Spain, z and soft c (before e or i) are pronounced with a “th” sound, while in most of Latin America they’re pronounced as an “s” sound. Overall, both pronunciations are correct.

Why 11–15 are unique: they’re not formed from a pattern, and must be memorised

Numbers 11–15 in Spanish are unique because they do not follow the same clear pattern as later numbers.

Instead of being built from diez plus another number, each one has its own word: once, doce, trece, catorce, and quince. Because of this, it’s best to memorise them as a small group before moving on to numbers like 16, 17, and 18, where the pattern becomes easier to spot.

Spanish Numbers 16–29 (The Merged Forms)

Spanish numbers from 16 to 29 are called merged forms because they were originally written as separate words, but are now written as one word.

For example, dieciséis comes from diez y seis, meaning “ten and six”. Similarly, veinte becomes veinti- before joining with another number to form 21–29.

Number	Spanish	Pronunciation
16	dieciséis	dyeh-see-SAYS
17	diecisiete	dyeh-see-SYEH-teh
18	dieciocho	dyeh-see-OH-choh
19	diecinueve	dyeh-see-NWEH-veh
20	veinte	BAYN-teh
21	veintiuno / veintiuna	bayn-tee-OO-noh / bayn-tee-OO-nah
22	veintidós	bayn-tee-DOHS
23	veintitrés	bayn-tee-TREHS
24	veinticuatro	bayn-tee-KWAH-troh
25	veinticinco	bayn-tee-SEEN-koh
26	veintiséis	bayn-tee-SAYS
27	veintisiete	bayn-tee-SYEH-teh
28	veintiocho	bayn-tee-OH-choh
29	veintinueve	bayn-tee-NWEH-veh

Accent marks in 22–29: veintidós, veintitrés, veintiséis (why they have accents)

Some numbers in the 20s have accent marks because the stress falls on the final syllable

In Spanish, words that end in a vowel, n, or s are usually stressed on the second-to-last syllable. As a result, when the stress moves to the last syllable, Spanish uses an accent mark to show it.

For this reason, 22, 23, and 26 are written as veintidós, veintitrés, and veintiséis. In short, the accent tells you to emphasise the final sound.

Spanish Numbers 30–99

Spanish numbers from 30 to 99 follow a much simpler pattern. First, learn the tens: treinta, cuarenta, cincuenta, sesenta, setenta, ochenta, and noventa. Then, to make numbers in between, use y (“and”): treinta y uno = thirty-one, cuarenta y dos = forty-two.

The key difference is that 21–29 are written as one word (veintiuno, veintidós), while 31–99 are written as three words using y.

Spanish Numbers 100–1,000

Spanish numbers from 100 to 1,000 are mostly built around the word ciento, which means “hundred”. The main exception is 100 itself: when the number is exactly 100, you use cien. But when more numbers follow, cien changes to ciento.

For example:

• 100 = cien
• 101 = ciento uno
• 125 = ciento veinticinco
• 199 = ciento noventa y nueve

After that, you need to learn the main hundreds. Some are predictable, like doscientos and trescientos, but others are irregular, such as quinientos, setecientos, and novecientos.

Number	Spanish	Pronunciation
100	cien	SYEN
101	ciento uno / una	SYEN-toh OO-noh / OO-nah
200	doscientos	dohs-SYEN-tohs
300	trescientos	trehs-SYEN-tohs
400	cuatrocientos	kwah-troh-SYEN-tohs
500	quinientos	kee-NYEN-tohs
600	seiscientos	sayss-SYEN-tohs
700	setecientos	seh-teh-SYEN-tohs
800	ochocientos	oh-choh-SYEN-tohs
900	novecientos	noh-veh-SYEN-tohs
1,000	mil	meel

Next, to form numbers between the hundreds, simply add the remaining number afterwards:

Number	Spanish
234	doscientos treinta y cuatro
507	quinientos siete
618	seiscientos dieciocho
775	setecientos setenta y cinco
999	novecientos noventa y nueve

One important grammar note: hundreds can change gender when they describe a feminine noun. For example, 200 books is doscientos libros, but 200 houses is doscientas casas.

The three irregular hundreds, quinientos, setecientos, novecientos, must memorise

Three Spanish hundreds are irregular and need to be memorised: quinientos, setecientos, and novecientos. In other words, these mean 500, 700, and 900.

They do not follow the simple pattern you might expect, so it’s worth learning them as a small group before practising larger numbers.

Gender agreement for hundreds, doscientas mujeres (feminine form)

Hundreds in Spanish must agree with the gender of the noun they describe. In fact, this means numbers like doscientos, trescientos, cuatrocientos, and so on can change to a feminine form when used with feminine nouns.

For example, “200 men” is doscientos hombres, but “200 women” is doscientas mujeres. The same rule applies to other hundreds: trescientos libros but trescientas casas, cuatrocientos estudiantes but cuatrocientas personas.

Pronunciation Guide for Spanish Numbers

Spanish number pronunciation is usually consistent, but a few sounds are worth learning early. First, pay attention to the Spanish r.

For instance, in words like trece, the r is a quick tapped sound, similar to a very short “d” in English. Likewise, in words like cuatro, the r is also light and quick, not a heavy English r.

The letters b and v sound almost the same in Spanish, so words like veinte and nueve should not be pronounced with a strong English “v” sound.

Instead, the sound sits somewhere between English b and v, depending on the speaker and position in the word.

Another important difference is z and c before e or i. In Spain, these are often pronounced like “th”, so cinco can sound like “theen-ko”. 

In most of Latin America, they are pronounced like “s”, so cinco sounds like “seen-ko”. Overall, both pronunciations are correct.

Grammar Rules for Spanish Numbers

– Uno vs un vs una — uno before a pause/end of sentence, un before masculine nouns, una before feminine nouns (veintiún hombres, veintiuna mujeres)

– Gender agreement for hundreds — doscientos libros vs doscientas páginas

– Using numbers with nouns — no article needed (tengo cinco libros)

– Approximate numbers — unos veinte (about twenty)

Spanish Numbers in Practice

Spanish numbers are mostly straightforward, but a few grammar rules are important when you use them in real sentences.

Uno vs un vs una

The number 1 can be uno, un, or una, depending on where it appears. Specifically, use uno when counting or when the number appears on its own, especially before a pause or at the end of a sentence.

For example:

• Uno, dos, tres = One, two, three
• Tengo uno = I have one

First, use un before a masculine noun:

• un libro = one book
• un hombre = one man
• veintiún hombres = twenty-one men

Similarly, use una before a feminine noun:

• una casa = one house
• una mujer = one woman
• veintiuna mujeres = twenty-one women

Gender agreement for hundreds

Hundreds also change form when they describe feminine nouns. Masculine nouns use forms like doscientos, trescientos, and cuatrocientos, while feminine nouns change -cientos to -cientas instead.

For example:

• doscientos libros = two hundred books
• doscientas páginas = two hundred pages
• trescientos alumnos = three hundred students
• trescientas personas = three hundred people

Using numbers with nouns

In Spanish, you usually do not need an article between a number and a noun. In other words, the number goes directly before the noun.

For example:

• Tengo cinco libros = I have five books
• Hay diez estudiantes = There are ten students
• Compré tres entradas = I bought three tickets

Approximate numbers

To talk about approximate numbers, use unos or unas before the number. In other words, this works like “about” or “around” in English.

For example:

• unos veinte estudiantes = about twenty students
• unas treinta personas = around thirty people
• unos cien euros = about one hundred euros

Similarly, use unos with masculine nouns and unas with feminine nouns.

Ordinal Numbers in Spanish (1st–10th)

Ordinal numbers are used to show order, such as first, second, third, and fourth. Notably, in Spanish, the most common ordinal numbers to learn first are 1st to 10th.

English	Spanish
1st	primero
2nd	segundo
3rd	tercero
4th	cuarto
5th	quinto
6th	sexto
7th	séptimo
8th	octavo
9th	noveno
10th	décimo

A key rule is that primero and tercero shorten before masculine singular nouns. For example, el primero día is incorrect. Instead, you say el primer día, meaning “the first day”. Likewise, the same happens with tercero: el tercer piso means “the third floor”.

Ordinal numbers are useful for dates, floors, rankings, and order in a sequence:

• el primero de enero = the first of January
• el segundo piso = the second floor
• el tercer lugar = third place
• la quinta vez = the fifth time

In everyday Spanish, ordinal numbers are most common from 1st to 10th. For larger numbers, Spanish speakers often use regular numbers instead.

Large Numbers in Spanish

Once you know mil, Spanish large numbers become much easier to build. The word mil means 1,000. Notably, it does not need uno before it.

Number	Spanish
1,000	mil
2,000	dos mil
10,000	diez mil
100,000	cien mil
1,000,000	un millón
2,000,000	dos millones
1,000,000,000	mil millones
1,000,000,000,000	un billón

One important rule is that “one million” is un millón, not uno millón. For example, 1,500,000 is un millón quinientos mil.

Be careful with the word billón. In English, “billion” usually means 1,000,000,000. By contrast, in standard Spanish, this is mil millones.

The Spanish un billón usually means 1,000,000,000,000, which is “one trillion” in English. Because of this, it’s best to use mil millones when talking about an English-style billion.

The billion false friend

One of the most important number differences in Spanish is the word billón. It looks like the English word “billion”, but it usually means something different.

A billion in English normally means 1,000,000,000. In Spanish, however, this is mil millones, literally “one thousand millions”. In contrast, the Spanish word un billón usually means 1,000,000,000,000, which is “one trillion” in English.

This is especially important in financial, business, and news contexts. If you see un billón in Spanish, do not automatically translate it as “one billion”. Check the context carefully, because it may mean “one trillion”.

Spanish Numbers FAQ

How do you say 1 in Spanish?

The number 1 in Spanish can be uno, un, or una, depending on the context. First, use uno when counting on its own: uno, dos, tres. Use un before a masculine noun, such as un libro, and una before a feminine noun, such as una casa.

What are the numbers 1 to 10 in Spanish?

The numbers 1 to 10 in Spanish are: uno, dos, tres, cuatro, cinco, seis, siete, ocho, nueve, and diez. These are the first numbers you should memorise because they appear in many larger Spanish numbers.

How do you count to 100 in Spanish?

To count to 100 in Spanish, start by learning 1–15, then the merged forms from 16–29, such as dieciséis and veintidós. From 30 onwards, Spanish uses a clear pattern with y, meaning “and”: treinta y uno, cuarenta y dos, cincuenta y tres. Finally, the number 100 is cien.

What is the number 1,000 in Spanish?

The number 1,000 in Spanish is mil. Unlike English, Spanish does not usually say “one thousand” as uno mil. You simply say mil.

How do you say billion in Spanish?

This depends on what you mean by “billion”. In everyday English, a billion usually means 1,000,000,000. In contrast, in Spanish, this is normally mil millones, literally “one thousand millions”. The word un billón traditionally means 1,000,000,000,000, one trillion in English, so it can cause confusion if translated directly.
