Lithuania IBAN validator
How the IBAN format works
- Format
- LT + 2 check digits + 5-digit bank code + 11-digit account number (20 chars)
- Example
- LT121000011101001000
Things to watch for
- 20 characters total, all numeric
^LT[0-9]{2}[0-9]{5}[0-9]{11}$A Lithuanian IBAN is 20 characters, entirely numeric after the country code: “LT”, two check digits, a 5-digit bank code, and an 11-digit account number. It’s one character shorter than Latvia’s IBAN and structured differently from Estonia’s, despite all three Baltic states sharing a common accession timeline into the EU and SEPA — each kept the account-numbering length its own domestic banking system already used rather than converging on one shared Baltic template. Anyone paying a Lithuanian supplier, sending money to family in Lithuania, or filling in a SEPA transfer form needs all 20 digits correct, with the 5-digit bank code and 11-digit account number as the only two segments to get right.
How this validator works
This tool checks the “LT” prefix, confirms the bank-code block is 5 digits and the account-number block is 11 digits, then runs the real mod-97 checksum (ISO 7064) Lithuanian banks use to generate a valid IBAN — entirely in your browser, nothing sent to a server, no signup, result as you type.
What a pass doesn’t tell you
A pass confirms the 20 digits are correctly formed and internally consistent — not that the account exists, is open, or belongs to whoever you expect. This tool does no bank-code-to-bank-name resolution and never contacts the Bank of Lithuania or any commercial bank. If a Lithuanian IBAN fails, double-check it wasn’t padded or trimmed to match a neighboring country’s IBAN length by mistake — since Baltic IBANs look superficially similar but differ by a digit or two, that’s an easy slip when copying by hand.
Scope: Lithuanian IBAN structure and mod-97 checksum validation only — not payment processing, bank-name lookup, or confirming an account is active, none of which a client-side check can establish. Use this validator to catch a typo before a transfer fails; use your bank to confirm the account itself.

IBAN FAQ
What does a Lithuanian IBAN encode?
20 characters: 'LT', two check digits, a 5-digit bank code, and an 11-digit account number, all numeric — for example LT121000011101001000.
Is a Lithuanian IBAN the same length as its Baltic neighbors?
No — Lithuania's is 20 characters, one shorter than Latvia's 21 and different in structure from Estonia's, because each Baltic state kept its own domestic account-numbering length when converting to IBAN rather than standardizing on a shared regional format.
Does a pass confirm the bank code belongs to a real Lithuanian bank?
No. This tool checks structure and the mod-97 checksum only, with no bank-code-to-bank-name lookup and no contact with the Bank of Lithuania or any commercial bank. Confirming the account is open requires the account holder or your own bank.
