The present research is developed having as its target population the countries that are members or associates of the Andean Community - CAN as of December 31, 2019. The main objective is to describe the classifications by company size given by the related countries. The research is developed under a methodology with a mixed approach, descriptive and documentary type. The following research questions are posed: What are the variables used by the CAN countries for the classification of companies according to size? Is there a high dispersion among the quantitative variables used by the CAN countries for the classification of companies according to size? The research hypothesis is that "the CAN member or associate countries present a high dispersion in terms of their quantitative variables for business classification by size based on the simple average and standard deviation". As results, it is identified that all of them include the variable of annual net sales revenue and 89% the variable of number of workers, and that the quantification of these variables does not present high dispersion. Finally, new research topics are proposed.
