The Numbers in Spanish – From Zero to Millions!

The Numbers in Spanish, from Zero to Millions. Learn and Practice Them

Welcome to our grammar lesson about the Numbers in Spanish.

In this lesson, we will learn Spanish Cardinal Numbers (uno, dos, tres…) equivalent to the English “one, two, three…”.

At the end of the lesson you’ll find a Quiz for practice.

The Numbers in Spanish – List

From 0 to 10:

0cero
1uno
2dos
3tres
4cuatro
5cinco
6seis
7siete
8ocho
9nueve
10diez

From 11 to 15:

There is a trick: they all end in -ce.

11once
12doce
13trece
14catorce
15quince

From 16 to 19:

Another trick here: they all begin with dieci-:

16dieciséis
17diecisiete
18dieciocho
19diecinueve

From 20 to 29:

20 is veinte, and the rest are still written with one word, beginning with veinti-.

20veinte
21veintiuno
22veintidós
23veintitrés
24veinticuatro
25veinticinco
26veintiséis
27veintisiete
28veintiocho
29veintinueve

From 30 to 99:

From 30 on, whenever there are units in the number, it’s written with 3 words, and the middle word is y.

For example 35 = “thirty and five” = treinta y cinco.

30treinta
31treinta y uno
32treinta y dos
40cuarenta
43cuarenta y tres
50cincuenta
60sesenta
70setenta
80ochenta
90noventa
99noventa y nueve

Exactly 100:

We use the word “cien” only when it’s exactly one hundred, without tens or units.

100cien

From 101 to 999:

We need to learn the word for every hundred.

No word “y” right after the hundreds.

101ciento uno
110ciento diez
146ciento cuarenta y seis
200doscientos
280doscientos ochenta
300trescientos
388trescientos ochenta y ocho
400cuatrocientos
500quinientos
600seiscientos
700setecientos
800ochocientos
900novecientos
999novecientos noventa y nueve

From 1000 to 1999:

It is always “mil” plus the rest of the number.

No word “y” right after the thousands either:

1.000mil
1003mil tres
1040mil cuarenta
1872mil ochocientos setenta y dos

From 2000 to 999 999:

The trick is to separate it mentally into 2 numbers: the number formed by the last 3 digits, and the number formed by the rest.

Then, say each of those 2 numbers in order, with the word “mil” in between.

2000dos mil
2001dos mil uno
2480dos mil cuatrocientos ochenta
4300cuatro mil trescientos
37 000treinta y siete mil
37 600treinta y siete mil seiscientos
125 125ciento veinticinco mil ciento veinticinco
472 346cuatrocientos setenta y dos mil trescientos cuarenta y seis
999 999novecientos noventa y nueve mil novecientos noventa y nueve

From one million on:

We say how many millions.

Then, for whatever comes after the millions, we follow the rules learned in this lesson.

No word “y” right after the millions either:

1 000 000un millón
2 000 000dos millones
3 500 000tres millones quinientos mil
55 248 248cincuenta y cinco millones doscientos cuarenta y ocho mil doscientos cuarenta y ocho

What’s the difference between “uno, un, una”?

In the first table of this lesson, we have shown that the number “one” in Spanish is “uno”. But it also can be “un” or “una”, depending on the specific sentence:

If it refers to a feminine noun, always una:

Tengo una lavadora.
I have one washing machine.

Tengo una.
I have one. (we still mean “lavadora“, even though we don’t mention it explicitly)


If it refers to a masculine noun, then choose un if it comes right before the noun, and uno if it doesn’t:

Tengo un coche.
I have one car.

Tengo uno.
I have one. (we still mean “coche“).


This phenomenon happens with any number that ends in “uno”.

For example, with veintiuno (21):

Tengo veintiuna lavadoras.
I have twenty one washing machines.

Tengo veintiún coches.
I have twenty one cars.

Or with ciento uno (101):

Tengo ciento una lavadoras.
I have 101 washing machines.

Tengo ciento un coches.
I have 101 cars.
