Only a Passport? How to Pay in Argentina Without a DNI (2026)

Yes, you can pay in Argentina with only a passport. CacaoCash checks your identity with your passport, not a DNI, and then lets you pay any Mercado Pago or MODO QR and send pesos to any alias, CVU or CBU, with a 2.5% fee shown before you confirm. What still needs a DNI: your own peso account and receiving pesos.

The catch most people hit is not the DNI. It is the document they upload. This guide covers which document works for verification, why national ID cards and residence permits often fail, what a passport alone lets you do in Argentina, and what still requires a DNI.

Which document works for verification: your passport

CacaoCash's identity check is built around a passport. Upload the photo page of your passport and take the selfie when the app asks. That is the document the check expects, and the one most likely to go through on the first try.

The most common reason verification fails is uploading something else. These documents are often rejected:

• National ID cards, including European ID cards such as a Spanish DNI or a Dutch identity card. They are valid IDs at home, but the check in CacaoCash is set up for passports.
• Residence permits, such as a French titre de séjour or another country's residence card, even when they are valid and you live there legally.
• Other cards like a cédula from another Latin American country.

Other things that make a passport check fail: a blurry or cropped photo, glare over the data page, an expired passport, or a selfie in poor light. Lay the passport flat, show all four corners, and use daylight.

If your verification already failed

If you tried with an ID card or residence permit and the check failed, write to support from inside the app and ask whether your verification can be restarted with your passport. If they reset it, restart the app and upload the passport photo page.

What you can do in Argentina with only a passport

Once you are verified, a passport covers the payments most foreigners actually need:

Every QR payment or peso transfer in CacaoCash has a 2.5% fee, and the app shows it, together with the exact peso amount, before you confirm. Full detail is on the fees page.

What still needs a DNI in Argentina

• Opening a Mercado Pago account. Mercado Pago, Ualá, Brubank and similar wallets ask for a DNI during verification. More in Mercado Pago for foreigners.
• Opening an Argentine bank account. A pesos account at a bank asks for a DNI or a CUIT/CUIL tax number.
• Receiving pesos. Getting paid in pesos needs your own CBU or CVU, which means a local account, which means a DNI. CacaoCash does not give foreigners an alias or CVU to receive pesos, so with only a passport you can send pesos but not receive them.

The reason is structural. Every CBU and CVU is tied to a verified national identity in Argentina's financial system, and a DNI only comes after a residency process that takes months. On tourist status there is no shortcut.

Paying without a DNI: passport app vs foreign card

With only a passport, your two digital options are a foreign card at terminals or a passport-verified app that pays pesos. The rate is where they differ. Example for a US$50 payment, October 2026:

Assumptions: crypto dollar ≈1,598 ARS before the fee and non-resident card rate ≈1,465 (Fiserv/Posnet), October 2026. Rates move daily, see today's Argentine dollar rate. That works out to ≈6% to 10% more pesos with CacaoCash than with a foreign card. Why there are two rates at all: card dollar vs crypto dollar.

Cash still has a place: some small sellers prefer it, and a card is fine where there is a terminal. For the full picture of every option, read how to pay in Argentina as a foreigner.

What people try instead (and why it falls short)

• Asking a local to open an account in their name. It puts a friend or landlord legally on the hook for your money, and you never control the account.
• Getting a CUIT as a foreigner. Possible in some cases, but it usually takes a local tax representative, a registered address and weeks of paperwork.
• Living on a foreign card. Works at terminals, but many small merchants, rentals and services only take a transfer or QR, and you pay the non-resident card rate.
• Carrying cash. Useful as backup, but it means holding physical dollars and changing them, and it does not help where a QR or transfer is expected.

How to set it up with a passport

1. Download CacaoCash and sign up with your email. No DNI, CUIT, Argentine bank account or Argentine phone number.
2. Verify with your passport photo page and a selfie (not an ID card or residence permit).
3. Load dollars by ACH, SEPA, SWIFT or crypto.
4. Pay a QR or send pesos to an alias, CVU or CBU. Check the peso amount and the 2.5% fee, then confirm.

Frequently Asked Questions

Can I verify with my EU national ID card instead of a passport?

Use your passport. National ID cards, including European ones like a Spanish DNI or a Dutch ID, are a common reason verification fails. If it already failed, ask support in the app whether it can be restarted, then upload your passport.

Can I use a residence permit to verify?

Use your passport instead. Residence permits such as a French titre de séjour often fail the check even when they are valid.

Can I open Mercado Pago with only a passport?

No. Mercado Pago asks for a DNI to verify an account. With a passport you can still pay any Mercado Pago QR through CacaoCash.

Can someone send me pesos if I only have a passport?

Not to your own account. Receiving pesos needs a CBU or CVU in your name, which requires a DNI. CacaoCash lets you send pesos, not receive them.

Does the person I pay need CacaoCash?

No. They receive a normal peso transfer in their own bank or wallet and pay nothing to receive it.
