Turkey bank SWIFT code

Türkiye İş Bankası SWIFT Code (BIC) — ISBKTRISXXX & Branch Codes

Türkiye İş Bankası — literally "Turkey Business Bank" — was founded in 1924 by Mustafa Kemal Atatürk as the young Republic's first national bank, and is today Turkey's largest private-sector bank by assets. Its head-office SWIFT/BIC code is ISBKTRIS (11-character form ISBKTRISXXX), registered in Istanbul. This page gives you the Turkish head-office BIC, a branch code table, the London (ISBKGB2L) and Frankfurt (ISBKDEFF) overseas branch BICs, a sample Turkish IBAN, and a FAQ.

The table below lists representative İş Bankası branch BICs built from the ISBKTRIS base plus a 3-character branch suffix. Use the head-office code ISBKTRIS for personal wires; pick a branch code when the sending bank requires a specific branch or when you want faster internal routing inside İş Bankası's Turkish network.

The Republic's first bank: why İş Bankası is different

Türkiye İş Bankası was founded on 26 August 1924, the year after the Republic was proclaimed, with capital raised from Turkish shareholders and a mandate to finance the new country's trade and industry. Until then the Ottoman Bank — a Franco-British joint venture — had acted as the central bank of the Ottoman Empire and dominated Turkish finance. İş Bankası was set up to break that dependence, and Atatürk personally championed it; the famous story that he left his own İş Bankası shares to the Turkish Language and Historical Societies in his will is part of why the bank is still called "the Republic's bank".

That founding role matters for international payments because İş Bankası grew up financing Turkish foreign trade. It built Turkey's first correspondent-banking relationships, ran the country's first foreign-currency desks, and today still carries one of the deepest trade-finance franchises among Turkish banks. For a Chinese importer opening a letter of credit against a Turkish exporter, İş Bankası is one of the most natural issuing/confirming banks on the Turkish side, and its long-standing correspondent ties in Asia make it a common intermediary for CNY and USD flows into Turkey.

Overseas branches: London (ISBKGB2L) and Frankfurt (ISBKDEFF)

İş Bankası runs the widest overseas branch network of any Turkish private bank. The two branches that matter most for international wires are London (ISBKGB2L) and Frankfurt (ISBKDEFF). The London branch is the older of the two and clears GBP and USD into the İş Bankası group; the Frankfurt branch settles EUR over the German SEPA network and issues German IBANs (22 characters, starting with DE).

Use ISBKGB2L when the beneficiary's account is with the London branch (a UK account number, not a TR IBAN), and ISBKDEFF when the beneficiary banks with the Frankfurt branch (a German DE IBAN). For a transfer to a regular İş Bankası account inside Turkey, keep using ISBKTRIS with a 26-character TR IBAN. Confirm with the recipient which entity holds the account before you choose the BIC.

How to send money to an İş Bankası account

  1. Confirm whether the beneficiary's account is with İş Bankası in Turkey (BIC ISBKTRIS, TR IBAN), the London branch (BIC ISBKGB2L, UK account), or the Frankfurt branch (BIC ISBKDEFF, DE IBAN).
  2. Get the full 26-character Turkish IBAN (or 22-character German IBAN, or UK account number) from the recipient and validate the IBAN with the IBAN validator on this site.
  3. Pick the right BIC: ISBKTRIS for a TRY or USD transfer into Turkey, a branch code if the sending bank requires it, ISBKGB2L for GBP into the London branch, or ISBKDEFF for EUR into the Frankfurt branch.
  4. Enter the BIC, the IBAN, and the recipient's full name and address on your bank's wire form, then double-check every field before submitting.
  5. Keep the confirmation receipt and tell the recipient to expect the funds within the value date your bank quotes — usually 1–3 business days for SWIFT, same day for SEPA.

Turkish IBAN example for an İş Bankası transfer

Every Turkish IBAN is 26 characters and starts with TR. The five digits after the check digits are the bank code, which for İş Bankası is 00064. Here is a sample Turkish IBAN you can use to test a payment form before sending a real transfer:

Sample Turkey IBAN (26 characters)
TR59 0006 4005 1978 6457 8413 26
TR590006400519786457841326

A Turkish IBAN always starts with TR, followed by 2 MOD 97 check digits, a 5-digit bank code, a 1-character reserve, and a 16-character account number — 26 characters in total. The bank-code digits tie the IBAN back to this bank, so an IBAN and a SWIFT/BIC together fully identify the account and the institution for an international wire into Turkey.

Türkiye İş Bankası SWIFT code FAQ

What is the SWIFT code for Türkiye İş Bankası?
The head-office SWIFT/BIC code for Türkiye İş Bankası in Turkey is ISBKTRIS (11-character form ISBKTRISXXX), identifying the bank's general management office in Istanbul. Use it as the receiver-bank BIC for an international wire to an İş Bankası account in Turkey.
Is ISBKTRIS an 8- or 11-character SWIFT code?
ISBKTRIS is the 8-character primary (head-office) BIC. ISBKTRISXXX is the 11-character form, where XXX marks the primary office in Istanbul. A different 3-character suffix (e.g. 001 for the Istanbul Genel Müdürlük branch) is a branch code — append it to the 8-character base to target a specific İş Bankası branch in Turkey.
What SWIFT code does İş Bankası London use?
İş Bankası's London branch uses the BIC ISBKGB2L. London is İş Bankası's oldest overseas branch and a key hub for GBP and USD clearing into the İş Bankası group. Use ISBKGB2L when the beneficiary's account is with the London branch rather than with İş Bankası in Turkey.
Does İş Bankası have a branch in Germany (Frankfurt)?
Yes. İş Bankası operates a Frankfurt branch under the BIC ISBKDEFF, which settles EUR payments over the German SEPA network. Use ISBKDEFF when the beneficiary banks with İş Bankası's Frankfurt branch — for example a Turkish-owned business operating in Germany — and pair it with the recipient's 22-character German IBAN (DE...) rather than a Turkish TR IBAN.
Why is İş Bankası called the Republic's first bank?
Türkiye İş Bankası was founded on 26 August 1924 by Mustafa Kemal Atatürk, the year after the Republic was proclaimed, as the first truly national Turkish bank with Turkish capital and Turkish management. It was set up to finance the young Republic's trade and industry when the Ottoman Bank still dominated Ottoman-era finance. That founding role is why it is still called 'the Republic's bank' and why it carries unusual prestige in Turkish trade finance.
What IBAN do I use with an İş Bankası SWIFT code?
For a transfer to a Turkish İş Bankası account, use the recipient's 26-character Turkish IBAN, which starts with TR. The five digits after the check digits are the bank code, which for İş Bankası is 00064. The IBAN identifies the account; the SWIFT/BIC (ISBKTRIS or a branch code) identifies İş Bankası as the bank. For the London branch use ISBKGB2L with a UK account number, and for the Frankfurt branch use ISBKDEFF with a German DE IBAN. Validate the IBAN with the IBAN validator on this site before sending.

⚠️ Head-office BIC sourced from public bank disclosures; branch codes follow the public ISBKTRIS pattern and are representative. The London (ISBKGB2L) and Frankfurt (ISBKDEFF) branches are separate offices of the same bank. Always confirm the exact BIC and IBAN with the recipient's İş Bankası branch before sending funds.
