IBAN Structure Lithuania

Last reviewed: · Source: ISO 13616 / SWIFT IBAN Registry

Lithuania's IBAN has 20 characters in the format LTkk BBBB BCCC CCCC CCCC. After the country code LT and the check digits come a 5-digit bank code and the 11-digit account number. Lithuania has been in the euro area since 2015 and is fully SEPA-integrated. Vilnius has become a major EU fintech hub in recent years, so many European payment providers issue Lithuanian IBANs. For payments from EU/EEA banks to Lithuania, required routing details depend on the bank, currency and route; check them in advance with your bank.

Structural fields are based on the official SWIFT IBAN Registry. The editorial method and validation boundary are documented on our German editorial page (German).

Frequently asked questions

How do I check the length of an IBAN from Lithuania?
Remove spaces and count 20 characters. The first two characters are LT; the remaining positions follow LTkk BBBB BCCC CCCC CCCC. A different length is formally invalid for this country format.
What do the check digits in a Lithuania IBAN mean?
The two check digits are calculated from the complete IBAN using ISO 7064 MOD-97. They help detect format and transcription errors. A passing checksum does not confirm that an account exists or identify its account holder.
What should I do when an IBAN is formally invalid?
Check the country code, character count, letters and digits, and the check digits. Compare the entry with your bank records or ask the bank for the correct IBAN. This checker validates structure and checksum; it does not verify account ownership or payment approval.
