Sample Account Data

We provide some (fictitious) sample account data below to facilitate the testing of our web service. Included are examples of both correct and incorrect account data for each of the countries supported, together with information on how the parameters should be passed to the 'calculate_iban' function.

Sample IBANs found on the Web or with a connection to fraud

Our API reports the presence of a given IBAN on the Web and whether the IBAN is suspected to be used for fraudulent purposes.

Here are three examples of such IBANs which you can use for testing your implementation of an API client:

DE27100777770209299700 (blacklisted)

DE11520513735120710131 (blacklisted)

AT411100000237571500 (found on the Web - in this case, context matters. Of course, lots of legitimate IBANs are visible online).

calculate_iban("AL", "14901", "22010010999", "username", "password", "", 0)

Austria

Correct:

calculate_iban("DK", "5051", "1322617", "username", "password", "", 0)

Incorrect:
bank code: 7777
domestic account number: 77777
currently, no bank code or account number validations are performed, so this function call will lead to an invalid IBAN despite the fact that no error is found:

Malta

Correct:

IBAN: MT98MMEB44093000000009027293051

calculate_iban("MT", "44093", "9027293051", "username", "password", "", 0)

Monaco

Correct:
bank code: 1273900070 domestic account number: 0011111000H79
IBAN: MC1112739000700011111000H79

calculate_iban("MC", "1273900070", "0011111000H79", "username", "password", "", 0)

calculate_iban("MC", "1273900070", "0011111000L79", "username", "password", "", 0)

Please specify domestic bank account numbers from Monaco in their full length (in the example above, this means: including leading zeros), unless you only have the bank account number without its checksum. In the latter case, our system will automatically calculate and append the checksum, which can be handy, but which also has the disadvantage that our system might mistake a short account number which already has a checksum as a checksum-less number.

Netherlands

Correct:
domestic account number: 484869868
IBAN: NL18ABNA0484869868

calculate_iban("NL", "", "484869868", "username", "password", "ABNANL2A", 0)

Incorrect:
domestic account number: 484869867

calculate_iban("NL", "", "484869867", "username", "password", "ABNANL2A", 0)

In the Netherlands, there is no separate domestic bank identifier similar to the German "Bankleitzahl" or the UK/Irish "sort code". We have a database of domestic Dutch account number ranges and the corresponding banks, and we extrapolate from this collection for the purpose of automatically determining the bank from a domestic account number. This feature is used if you call calculate_iban without passing a BIC code. If, however, you want to reliably avoid any extrapolation error, you also may pass the BIC code (as shown above) for the purpose of identifying a bank.

Norway

Correct:
domestic account number: 15032080119
IBAN: NO5015032080119

calculate_iban("NO", "", "15032080119", "username", "password", "", 0)

Incorrect:
domestic account number: 15032080118

calculate_iban("NO", "", "15032080118", "username", "password", "", 0)

If the bank code (here: 1503) is already passed as part of the account number, as above, it does not need to be repeated in the bank code field (the second parameter, here left empty).

It is also possible to use the following call: calculate_iban("NO", "1503", "2080119", "username", "password", "", 0). In other words, you are free to either split the BBAN/account number combination which is commonly used as Norwegian "account number" into the two parameters for bank code and account number, or to just pass the whole structure as the account number parameter.

Poland

Correct:
domestic account number = IBAN without "PL": 37109024020000000610000434

calculate_iban("PL", "", "37109024020000000610000434", "username", "password", "", 0)

Incorrect:
domestic account number = IBAN without "PL": 37109024020000000610000435

calculate_iban("PL", "", "37109024020000000610000435", "username", "password", "", 0)

Portugal

Correct:
domestic account number: 0035.0683.00000007843.11
IBAN: PT50003506830000000784311

calculate_iban("PT", "", "003506830000000784311", "username", "password", "", 0)

Alternatively, if you would prefer to not enter the NIB checksum (11 in the example above), you may also call calculate_iban by passing the 8-digit bank code and the 11-digit account number (instead of 13 digits) as two separate parameters, for instance: calculate_iban("PT", "00350683", "00000007843", "username", "password", "", 0).

Incorrect:
domestic account number: 0781.0112.00000007843.10

calculate_iban("PT", "", "078101120000000784310", "username", "password", "", 0)

Spain

Correct:

United Kingdom

Correct:
Sort code: 40-48-65
domestic account number: 62136016
IBAN: GB32ESSE40486562136016

calculate_iban("GB", "404865", "62136016", "username", "password", "ESSEGB2L", 0);

It is also possible to include the hyphens in the sort code: calculate_iban("GB", "40-48-65", "62136016", "username", "password", "ESSEGB2L", 0)

For very few UK accounts, we know the BIC code. For this small subset, it can be left out like this:

calculate_iban("GB", "404865", "62136016", "username", "password", "", 0)

However, unfortunately, you will need to know the BIC code most of the time for converting UK BBANs to IBANs.
