How long is a Seychelles IBAN?

A Seychelles IBAN is 31 characters, one of the longest in the entire IBAN registry. It contains SC, two check digits, a 4-letter bank code, 20 digits covering branch and account information, and, unusually, a 3-letter currency code at the very end.

Why does a Seychelles IBAN end in letters like USD or SCR?

The final three characters are an ISO 4217 currency code identifying the denomination of the account, such as SCR for Seychellois rupees or USD for dollars. Only a handful of IBAN countries, Seychelles and Mauritius among them, embed the currency directly in the account identifier.

Is Seychelles part of SEPA?

No. Seychelles is an Indian Ocean nation outside the European payments area, so transfers from Europe are international SWIFT payments through correspondent banks. The IBAN's built-in currency code at least removes ambiguity about the account's denomination, which prevents one common class of payment errors.

Seychelles operates one of the most distinctive IBAN formats in the registry: 31 characters with the BBAN pattern ^[A-Z]{4}[0-9]{20}[A-Z]{3}$, ending in a plain-text currency code.

Structure

The official registry example is SC18 SSCB 1101 0000 0000 0000 1497 USD, a SWIFT registry test value, not a real account:

SC18 - country code and IBAN check digits
SSCB - 4-letter bank code, derived from the bank’s BIC
11 and 01 - branch and sort information within the 20-digit block
0000000000001497 - the account number, zero-padded
USD - the ISO 4217 currency code of the account

Currency in the account number

Embedding the currency is rare and genuinely useful. In most countries, a customer’s euro and dollar accounts have unrelated IBANs and the sender has no way to tell which is which; in Seychelles, the last three characters state it outright. The same underlying account held in rupees (SCR), dollars (USD) or euros (EUR) yields visibly different IBANs, and crucially different check digits, so pasting the wrong-currency variant fails validation rather than silently landing in the wrong denomination. The cost is length: at 31 characters, only a few formats in the registry are longer, and manual entry is correspondingly error-prone, which makes checksum validation before submission worthwhile.

Payment context

Seychelles is not in SEPA, and the rupee is not widely traded, so international transfers are SWIFT payments requiring the beneficiary bank’s BIC, with the offshore financial sector making compliance screening on this corridor routine. There is no national check digit beyond the ISO MOD-97 pair; the currency suffix is informational, not arithmetic.

A validating SC IBAN confirms structure and internally consistent check digits, nothing else. It cannot establish that the account is open or who controls it, and no Verification of Payee equivalent operates on payments to Seychelles. Verify beneficiary name, bank and currency through an independent channel before sending funds, and use the generator on this page if you need structurally valid test data.
