What is the CBU and CVU?
CBU (Uniform Banking Code)
The CBU is a 22-digit number that identifies each bank account in Argentina. It is mandatory for electronic transfers, automatic debits, and credits.
CVU (Uniform Virtual Key)
The CVU also has 22 digits and is used to identify virtual accounts, electronic wallets, and payment accounts. It allows instant transfers through the Immediate Payments (PI) system.
CBU/CVU Structure:
- Digits 1-3: Financial institution code
- Digits 4-7: Branch or location code
- Digit 8: First check digit
- Digits 9-21: Account number
- Digit 22: Second check digit
What validates this tool?
- ✅ Correct format of 22 digits
- ✅ Valid entity code
- ✅ Two check digits using a modulo 10 algorithm
- ✅ Difference between CBU and CVU
- ❌ Does not verify if the account exists or has funds
Important:
This tool only validates the format and mathematical structure of the CBU/CVU. It does not confirm if the account is active or if it belongs to a specific person. To verify account ownership, contact the financial institution directly.
