Comprehensive Guide to Hungarian IBAN Numbers (2024)
The Hungarian IBAN (International Bank Account Number) system follows the ISO 13616 standard and is essential for both domestic and international transactions. This guide provides everything you need to know about Hungarian IBAN numbers, including their structure, validation process, and practical usage.
1. Hungarian IBAN Structure
A Hungarian IBAN consists of:
- Country Code: “HU” for Hungary
- Check Digits: 2 digits for validation
- Bank Identifier: 3 digits (Hungarian bank code)
- Account Number: 16-24 digits (depending on the bank)
| Position | Component | Length | Example |
|---|---|---|---|
| 1-2 | Country Code | 2 letters | HU |
| 3-4 | Check Digits | 2 digits | 42 |
| 5-7 | Bank Code | 3 digits | 100 |
| 8-31 | Account Number | 16-24 digits | 123456781234567812345678 |
2. How to Calculate Hungarian IBAN
The IBAN calculation process involves several steps:
- Prepare the BBAN: The Basic Bank Account Number (BBAN) in Hungary consists of the 3-digit bank code followed by the account number (without hyphens).
- Add country code and check digits: The country code “HU” is added to the beginning, followed by “00” as placeholder check digits.
- Convert letters to numbers: Each letter is converted to a number (A=10, B=11,…, Z=35).
- Calculate modulo-97: The entire number is divided by 97, and the remainder is subtracted from 98 to get the check digits.
- Replace placeholder: The calculated check digits replace the “00” placeholder.
3. Validating Hungarian IBAN Numbers
To validate a Hungarian IBAN:
- Check the total length (28 characters for Hungary)
- Verify the country code is “HU”
- Move the first 4 characters to the end
- Convert letters to numbers (A=10, B=11,…, Z=35)
- Check if the number is divisible by 97 (remainder should be 1)
| Step | Action | Example (IBAN: HU4210012345678912345678) |
|---|---|---|
| 1 | Original IBAN | HU4210012345678912345678 |
| 2 | Move first 4 chars to end | 10012345678912345678HU42 |
| 3 | Convert letters (H=18, U=30) | 10012345678912345678183042 |
| 4 | Calculate modulo 97 | 10012345678912345678183042 % 97 = 1 |
| 5 | Validation result | Valid IBAN (remainder = 1) |

5. IBAN vs. Regular Account Numbers in Hungary
The transition from domestic account numbers to IBAN was completed in Hungary by February 1, 2016, when IBAN became mandatory for all SEPA (Single Euro Payments Area) transactions.
| Feature | Domestic Account Number | Hungarian IBAN |
|---|---|---|
| Format | 8-8-8 or 16-24 digits | 28 characters (HU + 26) |
| Usage | Domestic only | Domestic & international |
| Validation | Bank-specific | Standardized (ISO 13616) |
| Mandatory since | Before 2016 | February 1, 2016 |
| SEPA compatibility | No | Yes |
6. Practical Tips for Using Hungarian IBAN
- Always double-check the IBAN before sending payments, especially for large amounts
- For international transfers, you’ll also need the BIC/SWIFT code of the recipient’s bank
- Hungarian IBANs can be used for SEPA transfers in euros, even if the account is in HUF
- Some older systems might still ask for the domestic account number – you can extract it from the IBAN by removing the first 8 characters (HU + check digits + bank code)
- For business accounts, the IBAN structure is the same but may include additional reference information
7. Legal Framework and Regulations
The Hungarian IBAN system is regulated by:
- Act CXXXIX of 2013 on the Magyar Nemzeti Bank (Central Bank of Hungary)
- Government Decree 195/2015 on payment services
- EU Regulation 260/2012 establishing SEPA requirements
- ISO 13616:2007 standard for IBAN
These regulations ensure that Hungarian IBANs are compatible with international standards while maintaining the integrity of the domestic banking system.
8. Common Mistakes to Avoid
- Incorrect bank code: Using the wrong 3-digit bank identifier will make the IBAN invalid
- Hyphens in account number: The IBAN should contain the account number without hyphens
- Wrong check digits: These must be calculated precisely using the modulo-97 algorithm
- Mixing up characters: Common mistakes include confusing “0” with “O” or “1” with “I”
- Incorrect length: Hungarian IBANs must be exactly 28 characters long
- Using old account format: Some systems might still show the old 8-8-8 format, which needs conversion
9. IBAN and SEPA in Hungary
Hungary has been part of the Single Euro Payments Area (SEPA) since 2014. This means:
- Hungarian IBANs can be used for euro payments across 36 SEPA countries
- SEPA credit transfers typically arrive within 1 business day
- SEPA direct debits are also available for Hungarian accounts
- The maximum amount for SEPA instant payments is 100,000 EUR, processed in seconds
According to the European Central Bank, SEPA transactions accounted for 43% of all non-cash payments in Hungary in 2022, showing significant growth in cross-border payment integration.
10. Future Developments
The Hungarian banking system continues to evolve:
- Instant payments: The Hungarian National Bank launched its instant payment system in 2020, with most banks now supporting IBAN-based instant transfers
- Open banking: PSD2 regulations are being implemented, allowing third-party providers to access account information (with consent) using IBAN as the identifier
- Digital forint: The central bank is exploring a digital currency that would likely use IBAN-like identifiers for wallets
- Enhanced validation: New APIs are being developed to provide real-time IBAN validation services
The Magyar Nemzeti Bank (Central Bank of Hungary) publishes regular updates on payment system developments, including IBAN-related changes.

12. Frequently Asked Questions
Q: Can I use my Hungarian IBAN for euro payments?
A: Yes, Hungarian IBANs are fully SEPA-compatible. You can receive euro payments to your HUF account (the bank will convert the currency), or you can open a euro-denominated account with the same IBAN structure.
Q: How long does an IBAN-based transfer take in Hungary?
A: Domestic transfers between Hungarian banks typically complete within minutes. SEPA transfers to other countries usually take 1 business day, while SEPA instant payments (if supported) complete in seconds.
Q: What happens if I enter the wrong IBAN?
A: Most banks perform IBAN validation before processing payments. If the IBAN is invalid, the transfer will be rejected. If the IBAN is valid but belongs to someone else, the funds may be sent to the wrong account, and recovery can be difficult.
Q: Can I have multiple IBANs for the same account?
A: Typically, each account has one IBAN. However, some business accounts might have multiple IBANs for different currencies or purposes, all linked to the same main account.
Q: Is it safe to share my IBAN?
A: Yes, sharing your IBAN is generally safe as it’s needed for receiving payments. However, never share other sensitive information like online banking credentials or card details along with your IBAN.
Q: How do I find my IBAN in Hungary?
A: You can find your IBAN:
- On your bank statements
- In your online banking portal
- On your bank card (some Hungarian banks print it)
- By using your bank’s IBAN generator tool
- By calculating it from your account number using tools like this one
Q: What’s the difference between IBAN and SWIFT/BIC?
A: IBAN identifies your specific account, while SWIFT/BIC identifies your bank. For international transfers, you typically need both the IBAN (to route to your account) and the SWIFT/BIC (to route to your bank).
13. Conclusion
