IBAN Structure Hungary

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

Hungary's IBAN has 28 characters in the format HUkk BBBS SSSK CCCC CCCC CCCC CCCK. After HU and the two check digits come an 8-digit bank/branch block including a national check digit, followed by a 16-digit account block. Hungary is in SEPA as an EU member but uses the forint (HUF) — not a euro country. For international payments, routing details, fees and timing depend on the banks, currency and route; check them in advance with your bank.

Frequently asked questions

How do I check the length of an IBAN from Hungary?
Remove spaces and count 28 characters. The first two characters are HU; the remaining positions follow HUkk BBBS SSSK CCCC CCCC CCCC CCCK. A different length is formally invalid for this country format.
What do the check digits in a Hungary 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.
