How this service works
Validate a Spanish bank account number (20-digit CCC) with both check digits, identify the bank and compute its IBAN; also breaks down a Spanish IBAN. Computed locally; nothing stored.
Output
Returns a JSON object with the full CCC, computed IBAN (raw and formatted), bank name, entity code, branch code, control digits, account number, and a boolean indicating whether the account number is valid.
Example use cases
Pre-payment CCC verification
“Before I wire money to this supplier, can you check if their Spanish account number 00490001512310001111 is valid and confirm which bank it belongs to?”
CCC to IBAN conversion for SEPA transfer
“I need to make a SEPA transfer but only have the Spanish CCC 21000418450200051332 — can you convert it to an IBAN for me?”
Spanish IBAN breakdown and validation
“Can you parse this Spanish IBAN — ES9121000418450200051332 — and tell me whether it's valid, and what the entity code, branch, and account number are?”
Technical details
Endpoint
POSThttps://api.vextorium.com/validar-ccc-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate Spanish domestic bank account numbers (CCC format) or Spanish IBANs, identify the issuing bank, or convert between CCC and IBAN formats. All computation is local with no data stored, making it suitable for privacy-sensitive contexts. Prefer this over generic IBAN validators when you specifically need Spanish CCC check-digit validation and bank identification.
Side effects
- CCC is not exactly 20 digits — validation fails with invalid input error
- Check digits do not match — returns valido: false
- Unknown entity code — bank name may be null or unrecognized
- Malformed Spanish IBAN (wrong country code or length) — parsing fails
- Non-Spanish IBAN passed — not supported, unexpected result or error
