CBU vs CVU vs Alias in Argentina: What's the Difference and Which to Ask For (2026)

Updated Published 5 min read

TL;DR

A CBU is a bank account number, a CVU is the same for a wallet like Mercado Pago, and an alias is a short nickname pointing to either, all on Transferencias 3.0 (instant, free, 24/7). Normally you need a DNI to have one; CacaoCash gives foreigners an alias and CVU to send and receive pesos without a DNI.

If you've spent a week in Argentina, you've heard it: "pasame tu alias" or "te paso el CBU". Someone wants to pay you, or you want to pay them, and suddenly there's an acronym you've never seen. This guide explains what alias, CVU, and CBU actually mean, how they fit together, and how foreigners can send and receive pesos with them, without a DNI.

TermWhat it isWhere it livesWhen to ask for it
AliasA nickname like juan.perez.mp that points to a CBU or CVUAny bank or walletAlways ask for this first. It is what Argentines share.
CVU22-digit key of a digital wallet accountMercado Pago, Ualá, Naranja X, Personal PayMost individuals and freelancers
CBU22-digit key of a traditional bank accountBanks (Galicia, Santander, Nación, BBVA…)Landlords, companies, anyone paid into a bank

All three land in the same instant transfer system, so it never matters which one you get: pesos sent to an alias arrive exactly like pesos sent to the CBU behind it.

CBU, the bank account number

A CBU (Clave Bancaria Uniforme) is a 22-digit number that uniquely identifies a traditional bank account. It's the original way to route a transfer in Argentina. You'll be asked for it when paying invoices, rent, or anyone who banks the old-fashioned way.

CVU, the wallet version

A CVU (Clave Virtual Uniforme) is the exact same idea, also 22 digits, but for a virtual account: a digital wallet like Mercado Pago or Ualá rather than a bank. Functionally, sending to a CVU and sending to a CBU feel identical.

Alias, the human-friendly nickname

Nobody wants to dictate 22 digits. An alias is a short, memorable nickname, words separated by dots, like maria.flores.mp, that points to a CBU or CVU behind the scenes. When you "pass your alias," you're just handing over an easy label for your account.

How they all connect: Transferencias 3.0

All of these live on top of Transferencias 3.0, Argentina's interoperable instant-payment rail. It means a Mercado Pago wallet can pay a bank account, a bank can pay a wallet, and an alias can point anywhere, all instantly, free, and around the clock. It's why money moves so smoothly between Argentines.

The catch for foreigners

To have an alias, CVU, or CBU, you need an Argentine account, and that needs a DNI. So foreigners can read all the acronyms they like and still have nothing to give when someone says "pasame tu alias."

How CacaoCash fits in

CacaoCash gives foreigners both sides of this system without a DNI:

Step by step, with costs against a wire and Western Union: how to send money to Argentina from abroad.

  1. You get your own alias / CVU to receive pesos, just like a local.
  2. You can send pesos to anyone's alias, CVU, or CBU straight from your USD balance.
  3. Everything converts at the crypto dollar rate, so you're not losing ~10% to the non-resident rate.

In short: the same instant, free peso system Argentines use, opened up for foreigners, funded in dollars. And when a merchant shows a QR instead of asking for an alias, you can pay any Argentine QR without a DNI the same way.
