The Ultimate Guide to Italian Numbers

If you’re learning a foreign language knowing the numbers is essential to go shopping, tell people about your telephone number, your birthday, or to talk about the date. Italian numbers are pretty easy to remember and follow a simple and predictable pattern. Let’s start with the basics and by the end of this article you’ll be able to use and construct Italian numbers to one billion and up!

Italian numbers 1-10

Let’s see first how to count from one to ten. It’s not that difficult to remember these Italian numbers as some of them resemble the English ones.

Italian numbers English numbers
zero zero
uno one
due two
tre three
quattro four
cinque five
sei six
sette seven
otto eight
nove nine
dieci ten

Italian cardinal numbers never change according to the gender and number of the name they refer to. The only exception is uno, the number one. So, if referring to a feminine name, you will use the feminine suffix -a and say una instead:

Ho comprato una rosa.
I bought one rose.

Lucia ha tre figli e una figlia.
Lucia has three sons and one daughter.

Sometimes the feminine “una” drops the final -a and is shortened in un’, when the following feminine name begins with a vowel. Remember that this only happens with feminine nouns.

Ho solo un’arancia in frigo.
I’ve only got one orange in the fridge.

Italian numbers 11-20

After twenty, Italian numbers are pretty straightforward and are easy to form and remember. However, you need to learn the numbers from 1 to 19 by heart. After ten, the numbers keep a part of the root in some cases. For instance, undici (eleven) is similar to uno (one), and tredici (thirteen) is similar to tre (three) Let’s see how to count from 11 to 20:

Italian numbers English numbers
undici eleven
dodici twelve
tredici thirteen
quattordici fourteen
quindici fifteen
sedici sixteen
diciassette seventeen
diciotto eighteen
diciannove nineteen
venti twenty

Oggi è il quattordici Aprile.
Today is the 14th of April.

Marco ha diciannove anni.
Marco is nineteen years old.

Cardinal numbers in Italian can be used to indicate a quantity or a price, to tell the date and the time. Instead of saying 5 PM, Italians may use the number 17. For instance:

Che ore sono? Sono le diciassette.
What time is it? It’s 5pm (seventeen).

Abbiamo appuntamento alle quindici e trenta.
We have an appointment at 3.30pm (fifteen thirty).

Italian numbers 21-100

Once you know how to count to twenty, you can build all the other numbers by using the base number, for instance venti (20), and adding any number from one to ten to create ventuno (21), ventidue (22), ventitré (23) and so on.

Italian numbers English numbers
venti twenty
ventuno twenty-one
ventidue twenty-two
ventitré twenty-three
ventiquattro twenty-four
venticinque twenty-five
ventisei twenty-six
ventisette twenty-seven
ventotto twenty-eight
ventinove twenty-nine
trenta thirty

You can see how after twenty you just need to use the root of the number and then add uno (1), due (2), tre (3), quattro (4), etc. Remember that the numbers venti (20), trenta (30), quaranta (40), cinquanta (50), sessanta (60) and so on always drop the final vowel when combined with uno (1) and otto (8). For instance:

  • venti (20): ventuno (21), ventotto (28)
  • trenta (30): trentuno (31), trentotto (38)
  • quaranta (40): quarantuno (41), quarantotto (48)
  • cinquanta (50): cinquantuno (51), cinquantotto (58)
  • sessanta (60): sessantuno (61), sessantotto (68)
  • settanta (70): settantuno (71), settantotto (78)
  • ottanta (80): ottantuno (81), ottantotto (88)
  • novanta (90): novantuno (91), novantotto (98)

Tre (3) is written without an accent, but when it’s the smaller digit of numbers such as ventitré (23), trentatré (33) quarantatré (43) and so on it is written with an acute accent.

30 – trenta 40 – quaranta 50 – cinquanta
31 – trentuno 41 – quarantuno 51 – cinquantuno
32 – trentadue 42 – quarantadue 52 – cinquantadue
33 – trentatré 43 – quarantatré 53 – cinquantatré
34 – trentaquattro 44 – quarantaquattro 54 – cinquantaquattro
35 – trentacinque 45 – quarantacinque 55 – cinquantacinque
36 – trentasei 46 – quarantasei 56 – cinquantasei
37 – trentasette 47 – quarantasette 57 – cinquantasette
38 – trentotto 48 – quarantotto 58 – cinquantotto
39 – trentanove 49 – quarantanove 59 – cinquantanove
60 – sessanta 70 – settanta 80 – ottanta 90 – novanta
61 – sessantuno 71 – settantuno 81 – ottantuno 91 – novantuno
62 – sessantadue 72 – settantadue 82 – ottantadue 92 – novantadue
63 – sessantatré 73 – settantatré 83 – ottantatré 93 – novantatré
64 – sessantaquattro 74 – settantaquattro 84 – ottantaquattro 94 – novantaquattro
65 – sessantacinque 75 – settantacinque 85 – ottantacinque 95 – novantacinque
66 – sessantasei 76 – settantasei 86 – ottantasei 96 – novantasei
67 – sessantasette 77 – settantasette 87 – ottantasette 97 – novantasette
68 – sessantotto 78 – settantotto 88 – ottantotto 98 – novantotto
69 – sessantanove 79 – settantanove 89 – ottantanove 99 – novantanove

In Italy, you can sometimes hear people using random numbers – for instance ottantadue (82) or sessantotto (68) – to refer to the correspondent year and talk about past events.

Sono nato nell’82.
I was born in 1982.

Il ’68 fu un anno di cambiamenti sociali e politici.
1968 was a year of political and social changes.

Italian numbers 100 – 1 billion

Now that you know how to count from one to 99 in Italian, let’s see how to count from 100 and up. Learning about numbers greater than one hundred is useful to talk about years or higher-priced items. One hundred is cento in Italian. The hundred numbers follow the same English pattern. You will use the smaller number and add hundred after it; for instance, to say 200, in Italian you will use due (2) + cento (100) = duecento (200).

cento 100
centouno 101
centocinquanta 150
duecento 200
trecento 300
quattrocento 400
cinquecento 500
seicento 600
settecento 700
ottocento 800
novecento 900
mille 1.000
milleuno 1.001
milleduecento 1.200
duemila 2.000
cinquemila 5.000
diecimila 10.000
quindicimila 15.000
centomila 100.000
cinquecentomila 500.000
un milione 1.000.000
cinque milioni 5.000.000
un miliardo 1.000.000.000

When constructing bigger numbers, Italian and English have some differences. For instance, there is no Italian equivalent of the English way of saying “eleven hundred” or “fifteen hundred”. Italians would instead say one thousand one hundred, “millecento” (1100) or one thousand five hundred, “millecinquecento” (1500).

Ho speso milletrecento euro per riparare la macchina.
I’ve spent 1.300 euros to fix the car.

Cento (100) has no plural. Cento numbers are formed by using the small digit number (1 to 9) and then adding hundred in the end, just like in English. For instance: cento (100), duecento (200), trecento (300), quattrocento (400), cinquecento (500), seicento (600), settecento (700), ottocento (800), novecento (900).

Ho speso trecento euro per quel vestito.
I paid 300 euros for that dress.

Questa casa fu costruita duecento anni fa.
This house was built two hundred years ago.

Unlike cento, which remains unchanged, mille (1000) has the plural form mila.

  • mille 1000
  • duemila 2000
  • tremila 3000
  • quattromila 4000
  • cinquemila 5000
  • seimila 6000
  • settemila 7000
  • ottomila 8000
  • novemila 9000

Milione (million) and miliardo (billion) also have a plural form which is milioni and miliardi.

A Roma ci sono 3 milioni di abitanti.
In Rome, there are 3 million inhabitants.

Il governo ha speso molti miliardi di dollari.
The government has spent several billions of dollars.

Italian ordinal numbers

Italian ordinal numbers are used to put things “in order” and are the equivalent of the English “first, second, third”, and so on. After 10 they are very easy to form, so you just need to memorize the ordinal numbers from one to ten:

Italian English
primo first
secondo second
terzo third
quarto fourth
quinto fifth
sesto sixth
settimo seventh
ottavo eighth
nono ninth
decimo tenth

Oggi ho il mio primo colloquio di lavoro.
Today I’m going to have my first job interview.

All Italian ordinal numbers change according to the gender and number. If they refer to a feminine name you need to add the feminine suffix -a, while if they refer to a plural name, you need to add the suffix -i for plural and masculine names, and the suffix -e for plural, feminine names.

Domani andrò a Milano per la terza volta.
Tomorrow I will go to Milan for the third time.

Lucia e Maria sono stata le quarte ad entrare.
Lucia and Maria were the fourth to enter.

Due terzi della popolazione sono soddisfatti dell’operato del governo.
Two thirds of the population are satisfied with the government actions.

Ho una vista di 10 decimi da tutti e due gli occhi.
I have 20-20 vision (10/10 in Italian) with both eyes.

After ten, ordinal numbers are simply formed by adding the suffix -esimo to the cardinal number. You will need to drop the last vowel of the number and simply add –esimo. For instance, to say “eleventh” in Italian, you will drop the final vowel in undici (11) and add –esimo: undic-esimo.

Italian English
undicesimo eleventh
dodicesimo twelfth
tredicesimo thirteenth
quattordicesimo fourteenth
quindicesimo fifteenth
sedicesimo sixteenth
diciassettesimo seventeenth
diciottesimo eighteenth
diciannovesimo nineteenth
ventesimo twentieth
cinquantesimo fiftieth
centesimo hundredth
millesimo thousandth
milionesimo millionth
miliardesimo billionth

Le tecnologie del ventesimo secolo hanno cambiato il nostro stile di vita.
The twentieth century technology has changed our lifestyle.

I risultati saranno pubblicati il cinquantesimo giorno dopo l’esame.
The results will be published the fiftieth day after the exam.

The only exception includes numbers ending in tré. Those numbers will just drop their accent and remain unchanged when esimo is added:

Papa Giovanni Ventritreesimo.
Pope John 23rd.

Sono il quarantatreesimo in fila alle poste.
I’m the 43 rd in the waiting line at the post office.
