IBANIsValid

Validates a BIC and IBAN code

Live Demo

To connect to this service you'll need to use one of these endpoints:

JSON

Open API

SOAP

Description

Checks if a BIC is a valid UK or Ireland BIC code, and retrieve additional information about the associated bank.

If an IBAN is also specified, checks if it is a potentially valid IBAN for that BIC.

Credit Usage

Requests to this method do not consume credits, but you must have some BankAccountValidation credits available.

Parameters

The following parameters can be supplied to this method

username	username See the available authentication methods. If you are using username & password authentication, specify the username to authenticate as. If you are using API Key authentication and you are not using the JSON, Javascript or ADO APIs, use your API Key here with the prefix `apikey-`, e.g. `apikey-ABCD-1234-EFGH-5678`
password	password If you are using username & password authentication, specify the password to use for authentication. Otherwise leave this blank.
bic	bic The BIC to validate.
iban	iban If specified, indicates the IBAN to validate along with the `bic`. Leave blank to validate the BIC only.

Advanced Options
