How do you register your address in Argentina in 2026?

Most movers begin with a written lease or temporary rental agreement that shows the street address and your name. A recent electricity, gas, water, or internet bill for that unit helps when the bill is in the landlord’s name if you also carry a landlord authorisation letter. Extended hotel or temporary stay receipts can bridge the first weeks when a long lease is not ready.

When a counter asks for a certificado de domicilio (address certificate), you typically request it at the local comisaría (police station) for the barrio where you live. Bring passport or DNI progress papers, proof you occupy the address, and photocopies. Rules and forms vary by province and City of Buenos Aires practice, so ask the desk which exact template they accept before you queue for hours.

Migraciones radicación files expect a coherent domicilio. RENAPER DNI appointments also want address evidence that matches your barrio: Get a DNI. Banks and fintech onboarding ask for the same street line once CUIL exists: Get a CUIL and Open a bank account. Prepaga enrolment often accepts a lease, hotel receipt, or utility pack before the plastic DNI arrives: Choose health insurance and Enrol in public health.

Update every file when you move barrios. A Palermo lease followed by a Belgrano move without changing Migraciones, bank, and prepaga records creates mismatched KYC and failed deliveries.
