I needed some IBANs for a unit test and was happy to find your generator; however, I think you've got a subset of IBANs that are in error. Either that, or the documentation at ECBS and the checkiban Javascript at UN/CEFACT is in error.

According to ECBS's notes on French IBANs (http://www.ecbs.org/iban/france-bank-account-number.html, the IBANs for

• French Guyana
• French Polynesia
• French Southern Territories
• Guadeloupe
• Martinique
• Mayotte
• New Caledonia
• Reunion
• Saint Pierre et Miquelon
• Wallis and Futuna Islands

should all begin with "FR", despite those territories all having their own ISO codes.

R.a. Porter,

You are right! The documentation at ECBS are correct. I have updated the tool accordingly.

I am looking for this, I have some questions, I work with financial questions on behalf of clients in Sweden, please contact me at [email protected] , thank you.

Hi,
I just wondered how you could be sure the IBANs were fictitious? I'd like to use some for testing but would be happier if reassured that these IBANs didn't belong to someone...somewhere. Or is there anyway of knowing this?

Thanks.

Does the random IBAN genarator generate actual account numbers?

For an app I am working on, this would be necessary. Can it be done to first generate a random country code & then proceed with the corresponding IBAN length? How close would the result be to 'hitting' an existing account number?

Looking forward to your reply.
If you want to know more about the app & its use, let me know

Lisa and Jochem,

I have created this tool to generate RANDOM Iban numbers for TEST purposes. I use these numbers to test my software. It randomly generates account numbers, then calculates valid checksums. I can not give any assurances that these account numbers does not belong to someone.

We have been using your generator to test Online-Shops after implementation of SEPA. It works like a charm. Thank you very much for that!

The spanish IBANs are all incorrect.

According the page http://www.ibancalculator.com/iban_validieren.html

The checksums in the account numbers are incorrect.

Joe,

Spanish bank account numbers (BBAN) are made up of 20 digits.

For example: 2100 2527 33 1234567890
-2100 is the name of the bank (ie. La Caixa)
-2527 is the branch code (ie. Mijas Pueblo)
-33 is the security code
-1234567890 is the 10 digit account number.

And other countries have BBAN numbers which are differently formatted.

This tool does not create correct or valid BBAN numbers.
The BBAN numbers are RANDOMLY generated.
Based on the randomly generated BBAN number the correct two digit checksum is calculated.

Thanks for this service. Its very useful of us who need to test systems with IBAN insertion.

Can you please provide a RESTful (or not) API that takes the same inputs and provides the same outputs as mentioned on this page? I would like to integrate that into my test cases.

The German IBANs do not work. I get a SEPA conversion failure. The only one working properly, is the one found within the table of countries.

Hi

Thanks for this very useful tool.

Seems that some of the generated IBANs are not valid per Finnish IBAN rules. Example: FI9430968691055442.

See link for details:
This IBAN has the correct length for this country (Finland).
The checksum in the account number is incorrect.
The IBAN checksum is correct.

Hello there,

I'm not sure to be in the right place. I'm looking for a system which be able to generate random IBAN/BIC numbers all associated to my real IBAN/BIC numbers.

Is this possible ?

This would allow me to receive payments from my clients without they see my real IBAN/BIC numbers.

If Yes, could someone explain me how to proceed ?

Thank You !

All the Testcountry2 IBANs fail in my testsuite, and they also fail in the validator on IBAN.com
Are they really correct?

I tried a Lot of german iban numbers but no one worked. Please help me

In Holland and I imagine in other European countries too; some services require a valid IBAN number to validate contact details even for some free services (email, hosting, etc). This generator worked perfectly and the number was validated as correct. Huge thank you for all the work put into this -- I will most definitely feature your tool in my blog whenever appropriate!

Regards,
Tim Base (WebHostWhat).

Bellissimo davvero

The generated Belgium accountnumbersdo not pass the AIBANcheck

I believe that Finland pattern is missing an "n" at the end :D

Hi,

Thanks for the service. One little question, for Portugal Iban, the lengh is correct but for some reason, the IBAN numbers are not correct. I'll explain myself, in PT the 4 first digits are always PT50 the fumbers can´t be aleatory and in the results given it change the 50 for 2 random number.
Anything that you could do about it?
Many thanks again for the tool

Hi,

There's a mistake for Portugal, the first 4 digits are always PT50 and not PT2 as written so the IBAN faile in any check.

Portugal    PT    PT2!n4!n4!n11!n2!n    25    PT50000201231234567890154

Can't it be fixed?
Many thanks for this amazing tool!!!

David A. the tool works correct.
PT50000201231234567890154 is a valid IBAN number for Portugal

Hi Robert,
Indeed, the IBAn below is correct as it start with PT50 but when you try to generate IBANs it doesn't always start with PT50, the two number after PT are aleatoric but it shouldn't be that way, it always start by PT50.

Robert, indeed, this IBAN correct as it start by PT50 but the generator is creating IBANs statring with PT + 2 random digit and they are incorrect. Sample from the generator:
PT68242377610674080226377
PT96464893348852697933085
PT63921282619659188180647
PT86162637289756359878169
PT64576898772375497298042
PT28575462034864805372067
PT66670386658437884795964
PT48551812607050173578659
None of those pass the IBAN validity tests.
Is it complicated to fix? Would you do it, please?
Many thanks again.

Hi Robert,

Regarding my mail below and your answer, the correct structure should be:
Current - Portugal PT PT2!n4!n4!n11!n2!n 25
Correct - Portugal PT PT50!n4!n4!n11!n2!n 25

There's any posibility for you to make this change in your algorithme to make the IBANs valide when checked by checking tools?
Really be amazing if you could do it, and congrat for the work you did!!
