Spanish Numbers 1-1000 (With Pronunciation)

July 3, 2026 · by the Sofia team

Spanish numbers follow a surprisingly logical system: memorize 1–15, learn the pattern for the rest, and watch out for about six irregular forms. This guide gives you every number from 1 to 1000 with pronunciation, the traps that catch English speakers (quinientos, not “cincocientos”), and how numbers actually behave in prices, phone numbers, and dates.

Numbers 1–30: The Ones You Must Memorize

The numbers 1–15 are pure memorization. From 16 on, Spanish starts combining — and from 21 to 29, it fuses the words together into a single word.

Two things to notice. First, 16–19 are literally “ten-and-six” (diez y seis) squeezed into one word: dieciséis. Second, 22, 23, and 26 carry a written accent (veintidós, veintitrés, veintiséis) because the stress falls on the last syllable.

The Tens and the “Y” Pattern

From 31 to 99, Spanish stops fusing and writes three separate words: ten + y (and) + unit. So 31 is treinta y uno, 47 is cuarenta y siete, 99 is noventa y nueve.

70setentaseh-TEHN-tah
80ochentaoh-CHEHN-tah
90noventanoh-BEHN-tah

The classic mix-up is sesenta (60) vs. setenta (70) — one letter apart, said fast, in a price. When in doubt, ask the vendor to repeat: ¿Puede repetir, por favor?

The Hundreds (Where the Irregulars Live)

One hundred alone is cien. The moment anything follows it, it becomes ciento: ciento uno (101), ciento cincuenta (150). There is no y after the hundred — 101 is ciento uno, never “ciento y uno.”

1000milmeel

Three hundreds are irregular, and they’re the ones learners invent wrong forms for:

  • 500 = quinientos (not “cincocientos”) — related to quince, not cinco
  • 700 = setecientos (not “sietecientos”) — the ie drops
  • 900 = novecientos (not “nuevecientos”) — same drop

And 1000 is just mil — never “un mil.” Mil quinientos = 1,500. Dos mil veintiséis = 2026.

The Tricky Ones: Uno, Veintiún, and Gender Agreement

Uno shortens and changes gender depending on what it counts:

  • Before a masculine noun, unoun: un peso, veintiún años (note the accent on veintiún), treinta y un días.
  • Before a feminine noun, unouna: una casa, veintiuna personas.
  • Standing alone (counting, answering “how many?”), it stays uno: —¿Cuántos quieres? —Uno.

The hundreds from 200 to 900 also agree in gender: doscientos pesos but doscientas personas, quinientos dólares but quinientas páginas. Cien and mil never change.

Using Numbers in Real Life

Prices

Prices in Latin America use the structure cuesta / son + number + currency:

  • ¿Cuánto cuesta? — How much is it?
  • Son ciento cincuenta pesos. — That’s 150 pesos.
  • Cuesta veintiún dólares con cincuenta. — It costs $21.50. (con introduces the cents)

In Mexico you’ll constantly hear varo or lana as slang for money, but the numbers themselves never change — which is why they’re worth over-learning.

Phone Numbers

Spanish speakers usually read phone numbers in pairs or single digits, not the three-four chunks English uses. The Mexican number 55 1234 5678 would be read: cincuenta y cinco, doce, treinta y cuatro, cincuenta y seis, setenta y ocho. If pairs overwhelm you in a live conversation, saying digits one by one (cinco, cinco, uno, dos…) is completely acceptable and always understood.

Dates and Years

Dates use plain cardinal numbers — no “fourth of July” ordinals except for the 1st:

  • el quince de septiembre — September 15th
  • el primero de enero — January 1st (the one ordinal)
  • Years are read as full numbers: 1999 = mil novecientos noventa y nueve, 2026 = dos mil veintiséis. Never split years the English way (“nineteen ninety-nine”).

Practice Drills That Actually Work

Reading a table doesn’t build recall — production does. Do these out loud:

  1. The odd-count drill. Count from 1 to 101 by twos, out loud, in under two minutes. Odd numbers force you through veintiuno, treinta y uno, cuarenta y uno — the forms that stall learners.
  2. The price gauntlet. Grab any receipt and read every line’s price in Spanish, cents included: cuatro dólares con noventa y nueve.
  3. The backwards ladder. Count down from 100 by sevens: cien, noventa y tres, ochenta y seis… Doing math in Spanish forces real retrieval instead of recitation.
  4. Year sprints. Say your birth year, this year, and the year you started learning Spanish. Then random years: 1521, 1810, 1985, 2001.
  5. Live listening. Numbers are the #1 thing learners understand on paper but miss at full speed. Practice hearing and saying them in real conversation — with a patient native speaker, or with Sofia, an AI Spanish tutor you can actually talk to, who will happily quiz you on prices and phone numbers until seiscientos setenta y seis rolls out automatically.

For a deeper reference on number grammar (including ordinals and fractions), the Real Academia Española’s guidance on numerals is the authoritative source.

Quick Answer Key: The Six Forms Everyone Gets Wrong

  1. veintiún años — accented, shortened before masculine nouns
  2. quinientos — 500, from quince
  3. setecientos — 700, no ie
  4. novecientos — 900, no ue
  5. cien vs. cientocien alone, ciento + anything
  6. mil — never “un mil”

If you own those six, everything else in the system is assembly.

FAQ

How do you say 100 in Spanish — cien or ciento?

Both, depending on position. Use cien when the number is exactly 100 or before a noun (cien pesos, cien personas). Use ciento the moment another number follows: ciento dos (102), ciento noventa (190).

Why is 500 “quinientos” and not “cincocientos”?

It’s an irregular form inherited from Latin quingenti, the same root that gives Spanish quince (15). The three irregular hundreds — quinientos (500), setecientos (700), novecientos (900) — simply have to be memorized.

Do Spanish numbers have gender?

Only some. Uno becomes un/una before nouns (veintiún años, veintiuna horas), and the hundreds 200–900 agree in gender (doscientas mujeres). Everything else — dos through diez, the teens, the tens, cien, mil — never changes.

How do you say 1,000 in Spanish?

Just mil — no article: mil pesos, mil novecientos ochenta. “Un mil” is always wrong. For multiples, use a number plus mil: dos mil, diez mil, cien mil.
