CBU

Also known as: Clave Bancaria Uniforme

Definition

CBU (Clave Bancaria Uniforme) is the 22-digit code that identifies a bank account in Argentina. Argentina's equivalent to CLABE in Mexico or IBAN in Europe.

LATAM context

Every Argentine bank account has a unique CBU. For usability, banks generate a "CBU alias": a memorable word or phrase that maps to the CBU (e.g. "MARTIN.PEREZ.GALICIA"). Both the CBU and the alias work to receive transfers.

Concrete example

CBU 0070123456789012345678 with alias MARTIN.PEREZ.GALICIA. Any transfer sent to the alias lands in that account automatically.

How it shows up on your bank statement

On Argentine statements your own CBU appears in the header alongside the account number and the holder's CUIT. Transfer transactions show the counterparty's CBU or alias. More and more banks show only the alias, which reads better but is also easier to confuse between similarly named people.

How does finO$ handle this?

finO$ extracts the CBU and CBU alias from every Argentine account and from the counterparties of each transfer. Supported across all Argentine banks.

Frequently asked questions about CBU

What's the difference between a CBU and an alias?

The CBU is 22 digits assigned by the bank and never changes; the alias is a short name the account holder picks and can update. Both identify the same account, but for reconciliation it's worth keeping the CBU on file, since the alias can change month to month.

Does the CBU work for dollar accounts too?

Yes, but it's a different CBU from the peso account. If you hold both currencies you'll see two CBUs, either on the same statement or on separate ones depending on the bank.
