Numbers in Spanish | 0 to 1 Billion Spanish Numbers

Ever needed to say your age, a price, a phone number, or a date in Spanish and suddenly paused? Numbers in Spanish are used in almost every daily conversation, so learning them early makes Spanish feel much easier.

The helpful part is that Spanish numbers follow patterns. Once you know numbers from 0 to 20, the tens, hundreds, and larger numbers become much easier to understand. Below, you will learn Spanish numbers from 0 to 1 billion with English translation, pronunciation, examples, cardinal numbers, ordinal numbers, even numbers, and odd numbers.

What Are Numbers in Spanish?

Numbers in Spanish help you talk about quantity, order, time, age, dates, money, addresses, and measurements. You hear them in shops, schools, restaurants, airports, and normal conversations.

There are two main number types you should know: cardinal numbers and ordinal numbers. Cardinal numbers tell “how many,” while ordinal numbers show position or order.

Examples:

• Tengo dos libros.
  I have two books.
• Vivo en el segundo piso.
  I live on the second floor.

Spanish Numbers 0–20 with Pronunciation

0 to 20 Spanish numbers are the base for many larger numbers. Learn these first because numbers like 16, 17, 18, and 19 are built from the idea of “ten plus another number.”

Some Spanish numbers in this group have unique forms, so read them slowly and practice the pronunciation aloud.

From 16 to 19, Spanish joins the words into one form:

• diez + seis = dieciséis
• diez + siete = diecisiete
• diez + ocho = dieciocho
• diez + nueve = diecinueve

Notice that dieciséis has an accent mark.

Numbers in Spanish 1–100

Numbers in Spanish 1-100 become easier when you learn them in groups. The numbers from 21 to 29 are written as one word, while numbers from 31 to 99 usually use y, which means “and.”

For example, treinta y uno means “thirty-one.” The structure is: ten + y + one.

Spanish Numbers 21–29

Numbers from 21 to 29 start with veinti-. This comes from veinte, which means twenty.

Accent marks appear in veintidós, veintitrés, and veintiséis because the natural stress needs to stay clear.

Spanish Tens from 30 to 100

From 30 onward, Spanish uses the tens word plus y plus the ones number.

Examples:

You use y only between the tens and ones from 31 to 99.

Correct:

• cuarenta y dos
  forty-two
• ciento cuarenta y dos
  one hundred forty-two

Not natural:

• ciento y cuarenta y dos

Complete Numbers in Spanish 1–100

Use this table for quick study and review. Read each Spanish number aloud before checking the pronunciation.

Spanish Numbers from 100 to 1,000

Spanish numbers from 100 to 1,000 follow a clear pattern. Use cien for exactly 100, but use ciento when another number comes after it.

For example, 100 is cien, but 101 is ciento uno.

Some hundreds are irregular:

• 500 = quinientos
• 700 = setecientos
• 900 = novecientos

More Examples from 100 to 999

Gender Agreement with Hundreds

Spanish hundreds from 200 to 900 change when they describe feminine nouns.

Examples:

• Hay doscientos libros.
  There are two hundred books.
• Hay doscientas casas.
  There are two hundred houses.

Spanish Numbers from 1,000 to 1 Billion

Large numbers in Spanish are useful for money, population, distance, news, business, and school subjects. The pattern is not difficult once you understand mil, millón, and mil millones.

In Spanish, 1,000 is simply mil. You normally do not say un mil for one thousand.

Examples of Large Spanish Numbers

Million and Billion in Spanish

Use un millón for one million and millones for more than one million.

For one billion, you should use mil millones. This avoids confusion because billón can mean a much larger number in many Spanish-speaking countries.

Best choice:

• 1,000,000 = un millón
• 2,000,000 = dos millones
• 1,000,000,000 = mil millones

Cardinal Numbers in Spanish

Cardinal numbers in Spanish tell how many people, things, places, or ideas there are. These are the numbers you use for normal counting.

You use cardinal numbers when talking about age, prices, quantities, dates, addresses, and phone numbers.

Examples:

• Tengo tres hermanos.
  I have three brothers.
• Necesito cinco minutos.
  I need five minutes.
• Hay mil personas en el estadio.
  There are one thousand people in the stadium.

Uno, Un, and Una

The Spanish number uno changes before nouns.

Examples:

• Tengo uno.
  I have one.
• Tengo un perro.
  I have one dog.
• Tengo una mochila.
  I have one backpack.

The same change happens with numbers ending in one:

Ordinal Numbers in Spanish

Ordinal numbers in Spanish show position or order. You use them for floors, chapters, competitions, school grades, rankings, and formal lists.

They answer the question “Which position?” instead of “How many?”

Examples:

• Es mi primer día.
  It is my first day.
• Vivo en el segundo piso.
  I live on the second floor.
• Ella ganó el tercer lugar.
  She won third place.

Primero and Tercero Before Masculine Nouns

Before a singular masculine noun, primero becomes primer, and tercero becomes tercer.

With feminine nouns, use the feminine form:

• la primera clase
  the first class
• la tercera pregunta
  the third question

Even Numbers in Spanish

Even numbers in Spanish are called números pares. These are numbers that can be divided by 2 without a remainder.

You often see them in math lessons, classroom activities, number patterns, and address numbers.

Example sentences:

• Dos es un número par.
  Two is an even number.
• Cuarenta es un número par.
  Forty is an even number.
• Los números pares terminan en 0, 2, 4, 6 u 8.
  Even numbers end in 0, 2, 4, 6, or 8.

Odd Numbers in Spanish

Odd numbers in Spanish are called números impares. These numbers cannot be divided evenly by 2.

They are common in math, games, number puzzles, and classroom practice.

Example sentences:

• Uno es un número impar.
  One is an odd number.
• Trece es un número impar.
  Thirteen is an odd number.
• Los números impares terminan en 1, 3, 5, 7 o 9.
  Odd numbers end in 1, 3, 5, 7, or 9.

How to Use Spanish Numbers in Daily Life

Spanish numbers are easier to remember when you connect them to daily situations. Use them for age, prices, time, dates, phone numbers, school, shopping, and travel.

Instead of only memorizing lists, practice short phrases you can use in conversations.

Age

Spanish uses tener for age. In English, we say “I am fifteen.” In Spanish, the idea is “I have fifteen years.”

Prices

You will hear numbers often when buying food, clothes, tickets, or anything in a shop.

Time

Spanish uses numbers to talk about time, but the sentence pattern changes depending on whether it is one o’clock or another hour.

Dates

Spanish usually uses cardinal numbers for dates. For the first day of the month, Spanish often uses primero.

Phone Numbers

Spanish speakers may say phone numbers digit by digit or in small groups. For you, digit-by-digit practice works well.

Example:

Common Mistakes with Spanish Numbers

Many learners understand Spanish numbers but make small mistakes when speaking quickly. These errors are normal, and you can fix them by learning the patterns.

Pay close attention to cien vs. ciento, uno vs. un/una, and the gender of hundreds.

Quick teacher note:

• Use uno when the number stands alone.
• Use un before a masculine noun.
• Use una before a feminine noun.
• Use cien for exactly 100.
• Use ciento when another number follows.
