Digits from one to nine are specific words: tu , chopa , tzona , tapa , ga’yo’ , xopa , gadyi , xuna’ , and ga .
The word for ten is chi. Numbers from eleven to nineteen are quite irregular, namely: chiptu  (contraction of chi be tu, 10+1), chipchopa  (contraction of chi be chopa, 10+2), chi’nnu , chi’da’ , chi’no’ , chi’no’ be tu  (15+1), chi’no’ be chopa  (15+2), chi’no be tzona  (15+1), and tu galo  (20-1).
Choapan Zapotec uses the vigesimal system, hence the tens are formed on the words for ten and twenty, namely: chi , galo , galo be chi  (20+10), chopa galo  (2*20), chopa galo chi  (2*20 + 10), tzona galo  (3*20), tzona galo chi  (3*20 + 10), tapa galo  (4*20), and tapa galo chi  (4*20 + 10).
When composed, numbers from twenty-one to twenty-nine are formed by saying the word for twenty (galo), then the word be (plus) and the digit (e.g.: galo be tu , galo be ga’yo’ ). From thirty-one to ninety-nine, the word be disappears (e.g.: galo be chi xopa , tzona galo tzona ).
