How to issue Italian IBANs
Italian IBANs are routed through Banca d’Italia and validated against both the IBAN Modulus-97 check and the legacy CIN check letter. The format carries an ABI bank code, a CAB branch code and a CIN national check character on top of the standard IBAN structure. Companion to the Dutch, Spanish and French IBAN pieces — this one walks through the Italian-specific layers, the Banca d’Italia registration, SEPA scheme adherence and the reporting catalogue that switches on at first issuance.
1. The Italian IBAN format
The Italian IBAN follows the ISO 13616 pattern IT2!n1!a5!n5!n12!c — 27 characters total:
- Positions 1–2: country code, always
IT - Positions 3–4: two IBAN check digits, calculated by Modulus 97 under ISO/IEC 7064
- Position 5: CIN national check letter (A–Z) — computed under a defined algorithm against the ABI, CAB and account-number components
- Positions 6–10: ABI — five-digit bank code identifying the credit institution, IMEL or IP, assigned by Banca d’Italia
- Positions 11–15: CAB — five-digit branch / agency code (Codice di Avviamento Bancario)
- Positions 16–27: twelve-character account number (numeric or alphanumeric) allocated by the PSP
Every Italian IBAN must pass both the IBAN Modulus-97 check and the legacy CIN check letter. Generators that validate only the outer ISO check produce IBANs that look valid but get rejected by Italian counterparties.
2. Getting the ABI and CAB codes
The five-digit ABI is the institution identifier under which Banca d’Italia recognises an Italian PSP. It is assigned during the authorisation process. The CAB identifies the specific branch or agency. Together they form the legacy “coordinate bancarie” structure that pre-dates SEPA and still anchors many domestic flows.
For passporting institutions establishing a branch in Italy, an ABI / CAB is assigned at the branch notification.
3. The BIC connection
Italy’s ABI maps to a SWIFT BIC under ISO 9362. Every authorised Italian PSP has a BIC for SEPA and SWIFT-routed payments. The BIC4 (first four letters) appears in cross-border counterparty checks. Apply for the BIC alongside the Banca d’Italia authorisation — do not wait for grant.
4. SEPA scheme adherence
Adherence to at least one EPC scheme is the precondition:
- SCT — baseline, required for receiving credit transfers
- SCT Inst — mandatory under the Instant Payments Regulation from defined dates
- SDD Core — optional but widely used in Italy, with Italian overlays on mandate handling
5. Clearing access in Italy
Italian PSPs settle euro payments through the national clearing system, interconnected with the wider EU instant-payments and large-value rails. Direct participation requires settlement-account access at Banca d’Italia. Indirect participation via a sponsor bank is the common route for smaller PSPs.
6. What switches on at first IBAN issued
- Banca d’Italia Segnalazioni — the Matrice dei Conti
- UIF AML reporting and the AUA daily archive
- CESOP reporting where applicable
- IPR statistical report
- Conduct returns under the ABF framework
7. Internal IBAN-generator rules
- Modulus-97 check at the IBAN level
- CIN check letter computed on the concatenation of ABI + CAB + account number under the defined algorithm
- Branch / agency code allocation — pick a structured scheme; Banca d’Italia looks at the structure at inspection
- Avoid IBANs matching well-known public-sector accounts — Agenzia delle Entrate, INPS — to prevent payment confusion
8. Passporting in vs. domestic licence
An IMEL or IP authorised elsewhere in the EU can issue Italian IBANs after establishing a branch in Italy or, in defined cases, on a Freedom of Services basis. See our branch vs Freedom of Services piece.
9. FAQ
What is the CIN check letter?
A single-character check at position 5 of the Italian IBAN, computed under a defined algorithm against ABI + CAB + account number. Mandatory and separate from the IBAN-level Modulus-97 check.
What is the “Coordinate bancarie”?
The legacy Italian banking-coordinates structure: ABI + CAB + CIN + numero di conto. Still used in domestic documents alongside the IBAN. The IBAN is the SEPA-standard form; coordinate bancarie remains visible in customer-facing flows.
How does Italy’s IBAN differ from Spain’s or France’s?
Italy has 27 characters (Spain: 24, France: 27); the structure includes the CIN check letter (Italy-specific), the ABI bank code (5 digits) and CAB branch code (5 digits) before the account number. Spain and France use different national overlays.
Are agents in scope of IBAN issuance?
Agents do not issue IBANs themselves; they distribute services of the authorised institution. The principal IMEL or IP holds the ABI and issues the IBANs. The agent must be OAM-registered separately — see our OAM piece.
What’s the typical timeline from authorisation to first IBAN?
For an Italian-authorised PSP, three-to-six months post-grant for a complete payments build covering BIC, SEPA scheme adherence, ABI/CAB registration, Banca d’Italia reporting infrastructure and operational testing.
Do I need to coordinate with the Italian banking association?
For new PSPs, yes — at a technical level. ABI standards govern domestic-message formats that overlay SEPA / ISO 20022. Familiarity with the relevant specifications is part of operational onboarding.
10. What to do, today
- Confirm whether your Banca d’Italia route is direct authorisation, branch passport-in, or Freedom of Services with Italian-IBAN issuance permission.
- Apply for the BIC alongside the Banca d’Italia file.
- Implement both the Modulus-97 and the CIN check in your IBAN generator.
- Decide direct vs indirect clearing participation.
- Map the post-go-live reporting catalogue before the first IBAN.
