Learning numbers in Spanish is one of the most essential steps when mastering the language. Whether you're shopping, telling time, or traveling, numbers come up everywhere. This guide will help you understand how to count from 1 to 1,000,000 in Spanish with clarity and confidence.

Mastering the Basics: Numbers 1 to 10

These are the foundation of all other Spanish numbers. Each one is unique and is often used in everyday language.

• 1 – uno

• 2 – dos

• 3 – tres

• 4 – cuatro

• 5 – cinco

• 6 – seis

• 7 – siete

• 8 – ocho

• 9 – nueve

• 10 – diez

Tip: Notice how these words don’t follow a specific pattern—memorization is key here.

Building Up: 11 to 20 Without Confusion

Spanish numbers from 11 to 20 are slightly irregular but still manageable once you get the hang of them.

• 11 – once

• 12 – doce

• 13 – trece

• 14 – catorce

• 15 – quince
  
  

• 16 – dieciséis
  
  

• 17 – diecisiete

• 18 – dieciocho

• 19 – diecinueve

• 20 – veinte

From 16 to 19, the structure combines "diez" (ten) and the next number—helpful for identifying patterns.

On a Roll: Counting by Tens from 30 to 100

Now things get easier. Once you learn the multiples of 10, combining them with single digits becomes a breeze.

• 30 – treinta

• 40 – cuarenta

• 50 – cincuenta

• 60 – sesenta

• 70 – setenta

• 80 – ochenta

• 90 – noventa

• 100 – cien

To say something like 35, you combine tens and ones using “y” (and):
35 – treinta y cinco

Going Higher: Hundreds and Their Patterns

In Spanish, hundreds are pretty consistent. Just like in English, you build on the base number.

• 100 – cien

• 101 – ciento uno

• 200 – doscientos

• 300 – trescientos

• 400 – cuatrocientos

• 500 – quinientos

• 600 – seiscientos

• 700 – setecientos

• 800 – ochocientos

• 900 – novecientos

Note the irregular forms like quinientos and setecientos—they're worth memorizing.

Thousand Talk: Cracking the Four-Digit Code

Once you hit 1,000, Spanish becomes super logical.

• 1,000 – mil

• 2,000 – dos mil

• 10,000 – diez mil

• 99,000 – noventa y nueve mil

• 100,000 – cien mil

• 999,999 – novecientos noventa y nueve mil novecientos noventa y nueve

Quick Trick: There’s no need to use “uno” before “mil”—just say mil, not uno mil.

The Big League: Reaching One Million

• 1,000,000 – un millón

• 2,000,000 – dos millones

When you want to say something like “1,000,000 books,” it becomes:
Un millón de libros (literally, "a million of books")

Notice the “de” that follows millón.

Final Tips to Sound Fluent with Numbers

• Practice with real-life situations: prices, dates, phone numbers.

• Pay attention to gender agreement when numbers are used with nouns (e.g., “una casa” vs “un coche”).

• Listen to native speakers use numbers—they often say them quickly, so exposure helps.

Conclusion: Counting with Confidence in Spanish

Mastering Spanish numbers from 1 to 1 million isn't just about memorisation, it's about patterns, practice, and usage. Once you get the logic behind how numbers are formed, you’ll be counting fluently in no time. Whether you’re a beginner or brushing up, numbers are a great way to grow your Spanish skills daily.
