Introduction to A1 Spanish Numbers

Numbers are essential for everyday communication in Spanish. Whether you’re telling your age, giving your phone number, or asking how much something costs, you need numbers. The good news? Spanish numbers follow logical patterns that become easier as you learn.

At the A1 level, you need to master numbers 0-30. Why 30? Because once you know 1-30, you already understand the patterns that will help you count all the way to 100 and beyond!


Numbers 0-15 (Memorize These First)

These numbers are unique and don’t follow a pattern. You must memorize them:

1uno9nueve
2dos10diez
3tres11once
4cuatro12doce
5cinco13trece
6seis14catorce
7siete15quince

Memory Tip: Practice counting from 0-15 every day until they become automatic. Use flashcards or count objects around your house.


Numbers 16-19 (The “Dieci” Pattern)

Starting at 16, a pattern emerges. These numbers combine “diez” (10) with the last digit:

NumberSpanishBreakdown
16dieciséisdiez + y + seis
17diecisietediez + y + siete
18dieciochodiez + y + ocho
19diecinuevediez + y + nueve

Important: These are written as ONE word. Do not add spaces. Also note the accent on dieciséis (16).

Memory Tip: Think “dieci” + the last digit. Dieci + seis = dieciséis.


Number 20 (veinte)

20 – veinte

This is the base for numbers 21-29.


Numbers 21-29 (The “Veinti” Pattern)

These numbers combine “veinte” (20) with the last digit. The ‘e’ drops from veinte:

NumberSpanishBreakdown
21veintiunoveinte + uno
22veintidósveinte + dos
23veintitrésveinte + tres
24veinticuatroveinte + cuatro
25veinticincoveinte + cinco
26veintiséisveinte + seis
27veintisieteveinte + siete
28veintiochoveinte + ocho
29veintinueveveinte + nueve

Important: Note the accents on veintidós (22), veintitrés (23), and veintiséis (26).

Memory Tip: Think “veinti” + the last digit. Veinti + cinco = veinticinco.


Number 30 (treinta)

30 – treinta

At A1 level, you only need to know up to 30. Numbers 31-100 are covered in our A2 guide.

Using A1 Numbers in Real Life

Telling Your Age

In Spanish, you use the verb “tener” (to have) to talk about age, not “ser” (to be).

EnglishSpanish
I am 25 years old.Tengo veinticinco años.
She is 18 years old.Ella tiene dieciocho años.
He is 30 years old.Él tiene treinta años.
How old are you?¿Cuántos años tienes?

Giving Your Phone Number

In Spanish, phone numbers are typically said digit by digit:

EnglishSpanish
My number is 5-5-5-1-2-3-4.Mi número es cinco, cinco, cinco, uno, dos, tres, cuatro.
Call me at 6-5-2-8.Llámame al seis, cinco, dos, ocho.

Basic Shopping and Prices

EnglishSpanish
It costs 5 euros.Cuesta cinco euros.
How much is it?¿Cuánto cuesta?
I want two apples.Quiero dos manzanas.
One coffee, please.Un café, por favor.

The Special Rule: Uno Becomes Un or Una

The number uno (1) changes form depending on what comes after it:

FormWhen to UseExample
unoWhen counting aloneuno, dos, tres…
unBefore masculine nounsun libro (one book)
unaBefore feminine nounsuna casa (one house)

Examples:

  • Tengo un hermano. (I have one brother.)
  • Tengo una hermana. (I have one sister.)
  • Quiero un café. (I want one coffee.)

Frequently Asked Questions

The Spanish numbers from 0 to 30 are: cero, uno, dos, tres, cuatro, cinco, seis, siete, ocho, nueve, diez, once, doce, trece, catorce, quince, dieciséis, diecisiete, dieciocho, diecinueve, veinte, veintiuno, veintidós, veintitrés, veinticuatro, veinticinco, veintiséis, veintisiete, veintiocho, veintinueve, treinta. Numbers 0–15 are unique and must be memorized; 16–19 follow the dieci pattern; 21–29 follow the veinti pattern.

Dieci is a contraction of diez (ten) plus y (and). In older Spanish, these numbers were written as three separate words — diez y seis — which over time fused into one word: dieciséis. The same pattern applies to 17–19: diecisiete, dieciocho, diecinueve. All are written as a single word today.

The final -e of veinte drops when it joins with the next word, giving the combining form veinti-. So veinte + uno becomes veintiuno, and veinte + cinco becomes veinticinco. This only happens for numbers 21 through 29 — at 30 the pattern stops, and numbers 31+ revert to three separate words (treinta y uno).

Four numbers between 0 and 30 carry a written accent: dieciséis (16), veintidós (22), veintitrés (23), and veintiséis (26). All other numbers in this range are written without accents. The accent marks where the stress falls and distinguishes these forms from their unaccented counterparts.

One word. Dieciséis is correct; diez y seis is not used in modern Spanish. The same rule applies to 17, 18, and 19: diecisiete, dieciocho, diecinueve. This is one of the most common writing mistakes at the A1 level.

Uno is used when counting by itself (uno, dos, tres…). Before a masculine noun it shortens to un: un libro (one book), un café (one coffee). Before a feminine noun it changes to una: una casa (one house), una manzana (one apple). The same rule applies to veintiuno — before a noun it becomes veintiún or veintiuna.

Use the verb tener (to have), not ser: Tengo veinticinco años (I am 25 years old), literally “I have 25 years.” To ask someone’s age: ¿Cuántos años tienes? The verb ser is never used with age in Spanish — soy veinticinco años is incorrect.

Phone numbers are read digit by digit, not as whole numbers. So 555-1234 is cinco, cinco, cinco, uno, dos, tres, cuatro. There is no “five hundred fifty-five” equivalent for phone numbers — each digit is said separately, usually with a brief pause or comma between groups.

Diez y seis is the older, three-word form; it is no longer standard in written Spanish. Dieciséis is the correct modern spelling — one word, with an accent on the second e. Use dieciséis in all writing. The same applies to 17–19 and to 21–29, all of which are written as single words.

After 0–30, move on to numbers 31–100, which follow a regular pattern: treinta y uno, treinta y dos… (thirty and one, thirty and two). These are covered in the A2 Spanish numbers guide. From there, the B1 level introduces hundreds and ordinals 1–10, and higher levels cover thousands, millions, and fractions.
