American Sign Language Numbers

Here you can learn how to sign different ASL numbers. It's not just about learning numbers 1-10, but also how to sign multiples, ages, money, time, and more! Each way to sign numbers is unique in American Sign Language.

More Numbers:


When you are signing a year, you would sign it as you would say it in English. For 1987, you would sign 19 and then 87. For the years 2000 and on, signers are signing them as 2-000 (sliding your hand with the 0 handshape to indicate multiple digits) or 2-00-1 (sliding your hand for the 0’s). Some signers use the sign for THOUSAND as part of the sign for years 2000 and up.

Phone Numbers and Addresses

When you are signing a phone number or address, you keep your palm facing away from you and sign each number. With a phone number, you also sign a short pause where the hyphens would be.


Fractions are signed exactly as they look. With your palm facing you, first sign the top number (the numerator), move your hand downward slightly, and sign the bottom number (the denominator). For example, to sign 1/2, you would sign “1,” move your hand downward slightly, and sign “2.”


Height is signed exactly the opposite of fractions. The number of feet is signed first, you move your hand upward slightly, and then sign the number of inches.

Letters and Numbers

When you are having a conversation involving both letters and numbers, you would slightly shake the numbers back and forth and sign the letters normally. This way, you distinguish between signing the numbers and letters.
