Format example only — a filler account body with correctly computed IBAN check digits. It is not a real account; national check digits inside the BBAN (if any) are not computed.

How a Turkey IBAN is built
A Turkey IBAN is always exactly 26 characters long. It opens with the ISO country code TR, followed by two check digits and a 22-character Basic Bank Account Number (BBAN). In SWIFT IBAN Registry notation the BBAN is 5n1n16c — that is 3 fields: 5 digits, 1 digit and 16 letters or digits. The BBAN carries the national bank identifier and the account number, so the same account keeps its domestic details inside the IBAN.
The BBAN is not purely numeric: it contains 16 alphanumeric positions, and 6 digit-only positions. Forms and databases that accept TR IBANs must allow upper-case letters after the check digits — stripping or rejecting them breaks valid numbers.
IBAN lengths range from 15 to 31 characters across the 62 countries we cover; at 26, Turkey sits on the longer side. Other countries whose IBANs are also 26 characters long: Iceland. Length alone therefore cannot tell them apart — always compare the country code too.
The check digits (62 in the example) follow ISO 7064 MOD-97-10. Move the first four characters to the end — 1234567890123456789012TR62 — then replace each letter with two digits (A = 10 … Z = 35), giving 1234567890123456789012292762. Divided by 97 this leaves a remainder of 1; any correctly typed Turkey IBAN gives 1, while a typo or two swapped characters almost always produce a different remainder.
On paper and in banking apps the IBAN is usually printed in groups of four (TR62 1234 5678 9012 3456 7890 12); in payment files and APIs it is sent without spaces. Turkey is outside SEPA, so international senders usually also need the bank's SWIFT/BIC code.

Yes. Besides the country code TR, the BBAN (5n1n16c) has 16 positions that may hold letters or digits. Keep the letters when you copy or store the IBAN — only spaces may be removed.
How do I check that a Turkey IBAN is valid?
Check that it starts with TR, has 26 characters, that the BBAN matches 5n1n16c, and that the ISO 7064 MOD-97 remainder equals 1. The checker on this page does all four in your browser; the IBAN Validator also handles bulk lists. A pass means the format is valid — not that the account exists.
Is Turkey part of SEPA?
No. Turkey is not in the Single Euro Payments Area. Its banks use the IBAN for incoming international transfers, which usually travel over SWIFT, so the sender often also needs the bank's SWIFT/BIC code.
