Numbers from 101 to 1 million in Spanish

For hundreds, we use:

100 – Cien
101 to 199 – Ciento 
200 to 299 – Doscientos 
300 to 399 – Trescientos
400 to 499 – Cuatrocientos
500 to 599 – Quinientos*
600 to 699 – Seiscientos
700 to 799 – Setecientos*
800 to 899 – Ochocientos
900 to 999 – Novecientos*

*Irregular: it doesn't follow the number + "cientos" pattern

For thousands:

1.000 – Mil 2.000 – Dos mil 3.000 – Tres mil etc.

For millions:

1.000.000 – Un millón 2.000.000 – Dos millones etc. 

Note: In most Spanish-speaking countries, we traditionally use periods, instead of commas, for thousands.

Note 2: Hundreds from 200 through 900 have gender in Spanish. When we use them as adjectives, we can either keep them masculine (cuatrocientos dieciséis gatos) or make them feminine (quinientas quince sillas).

Note 3: We don’t add any extra y when using hundreds. For example, 457 would be cuatrocientos cincuenta y siete; it would never be cuatrocientos “y” cincuenta y siete.
