How this service works
Landing page para tu negocio en 24 horas: textos, diseño para celular y botón de WhatsApp. Boceto gratis: ves la primera versión antes de pagar. USD 39 de lanzamiento.
Output
Returns a JSON object indicating whether the CBU/CVU is valid, whether each of the two check digit blocks passed, the account type (CBU or CVU), the 3-digit entity code, the 4-digit branch code, the bank name for major Argentine banks, the original input normalized to 22 digits, and a human-readable formatted version split into the two standard blocks. Also includes a note clarifying this is offline check-digit validation only and does not confirm account existence or ownership.
Example use cases
Pre-transfer CBU validation for payroll
“Before I run payroll, validate this list of employee CBUs — start with 0070999003000412345671 and tell me if it's a valid CBU and which bank it's from so I know there are no typos.”
Fintech onboarding account check
“A user just entered their CBU as 2850590940090418135201 during onboarding — can you check whether the check digits are valid and what bank that account belongs to before we save it?”
Marketplace payout account verification
“We need to pay a seller via CBU — their number is 0110606530060644458007, can you verify it's a valid CBU, get the bank name, and confirm the entity and branch codes look right?”
Technical details
Endpoint
POSThttps://landingen24h.com/api/x402/ar/cbu?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, offline, zero-latency validation of Argentine CBU or CVU numbers without sending data to a bank — ideal for pre-validating user input before storing or transacting, since no data is retained and results are instant. Prefer this over live bank API lookups when you only need format/check-digit correctness and basic bank identification, not account existence or balance confirmation.
Side effects
- Input CBU/CVU shorter or longer than 22 digits returns invalid result
- Non-numeric characters in input may cause parsing failure
- Unknown or smaller banks may not return a bank_name despite valid check digits
- CVU accounts may have limited bank name resolution since they belong to non-bank PSPs
- Network or service downtime returns HTTP error rather than validation result
