According to the Girl Scouts website, there are 12 varieties of cookies. Not all cookies are available in all regions at all times. Entering a zip code in the search box on the Girl Scouts website is one way to locate cookies and find out when they go on sale.
Thin Mints, Peanut Butter Sandwich/Do-Si-Dos, and Shortbread/Trefoil cookies are mandatory and produced each year. Five additional varieties are changed every year. Additional varieties include: Samoas/Caramel deLites, Peanut Butter Patties/Tagalongs, Lemonades, Savannah Smiles, Thanks-A-Lot, Dulce de Leche, Cranberry Citrus Crisps, Chocolate Chip Shortbread, and Thank U Berry Munch. All cookies are kosher and are produced by either ABC Bakers or Little Brownie Bakers.
