How to Get a CUIL Number in Argentina

Get your CUIL number at any ANSES office by bringing your passport, proof of address, and completed form. The process takes 15-30 minutes and the number is issued immediately. You'll need this for banking, working, and most official transactions in Argentina.

  1. Gather required documents. Bring your passport (original and photocopy), proof of address in Argentina (rental contract, utility bill, or sworn declaration), and your DNI if you have temporary/permanent residency. Download and complete Form PS.2.1 from the ANSES website beforehand.
  2. Find your nearest ANSES office. Use the ANSES office locator on their website or ask locals for directions. Major offices are in city centers and most neighborhoods. Check operating hours - typically 8 AM to 2 PM, Monday through Friday.
  3. Take a number and wait. Arrive early (before 9 AM) to avoid long lines. Take a number from the machine for 'CUIL' services. Wait times range from 30 minutes to 2 hours depending on location and time of day.
  4. Submit your application. Present your documents to the clerk. They'll verify your information and enter it into the system. The clerk will print your CUIL certificate on the spot - this is your official proof of the number.
  5. Save your CUIL number. Write down your 11-digit CUIL number immediately. Take a photo of the certificate. You'll need this number for every financial transaction, job application, and government service in Argentina.
Can tourists get a CUIL number?
Yes, tourists can get a CUIL for specific purposes like banking or legal work arrangements. However, many services still require temporary or permanent residency status.
How long does the CUIL number last?
Your CUIL number is permanent and stays with you even if you leave Argentina and return later. It never expires.
What if I don't have proof of address?
You can make a sworn declaration (declaración jurada) at a notary office stating where you're staying. This costs around $15-25 and is accepted by ANSES.
Do I need to speak Spanish?
Basic Spanish helps, but many ANSES offices in tourist areas have English-speaking staff. Bring a Spanish-speaking friend if you're not confident, or use translation apps.
