Do you mean simply your CUIT number from ANSES or do you mean proof from AFIP that you are paying monotributo taxes?
For just retrieving the number, if you have your DNI number, you should be able to print it out here filling out your data: http://www.anses.gob.ar/autopista/destacados/constancia-cuil.php
by clicking on the first link "Iniciar Consulta." The first link asks if you posses DU, Documento Único, which is your DNI number, to click there. Select Document Único and put in your DNI when prompted. If you don't have a DNI yet, you have to go to the second link for "other documents," such as a passport. Unfortunately, if you don't KNOW your CUIL/CUIT number, you cannot retrieve it from this page! If you don't have a DNI or the CUIL/CUIT number written down somewhere, you might have to go to ANSES with your passport in that case.
Thanks for your replies. Come to think about it I just need the number, and not the actual form. Do you think I can go to any ANSES office with my passport and ask for it?
