IBAN Validation API
curl --request GET \

{
    "iban": "BE71096123456769",
    "is_valid": true
}
It’s very simple to use; you only need to submit your api_key and an iban, and the API will tell you whether the IBAN is valid or not. Future versions of the API will include more detail about the submitted IBAN if it is valid.

​
Getting started

​
REST

The IBAN Validation API, like all of Abstract’s APIs, is organized around REST. It is designed to use predictable, resource-oriented URLs and to use HTTP status codes to indicate errors.

​
HTTPS

The IBAN Validation API requires all communications to be secured with TLS 1.2 or greater.

​
API Versions

All of Abstract’s APIs are versioned. The IBAN Validation API is currently on Version 1.

​
Your API Key

Your API key is your unique authentication key to be used to access Abstract’s IBAN Validation API. Note that each of Abstract’s APIs has a unique API key, so you will need different keys to access the IBAN Validation and Email Validation APIs, for example. To authenticate your requests, you will need to append your API key to the base URL.

​
Base URL

https://ibanvalidation.abstractapi.com/v1/

​
Validation endpoint

Abstract’s IBAN Validation API simply requires your unique API key and the IBAN number you’d like to check: 
https://ibanvalidation.abstractapi.com/v1/
? api_key = YOUR_UNIQUE_API_KEY
& iban = BE71096123456769
This was a successful request and the IBAN was valid, so the API will return the following: 
{
    "iban": "BE71096123456769",
    "is_valid": true
}

{
    "iban": "BE71096123456769",
    "is_valid": true
}

​
Request parameters

​
api_key
String
required
Your unique API key. Note that each user has unique API keys for each of Abstract’s APIs, so your IBAN Validation API key will not work for your IP Geolocation API, for example.
​
iban
String
required
The IBAN to validate. Note that the API will accept white spaces, so BE71 0961 2345 6769 is considered as valid as BE71096123456769.

​
Response parameters

The API response is returned in a universal and lightweight JSON format.
​
iban
String
The IBAN submitted for validation.
​
is_valid
Boolean
Is true if the IBAN submitted is valid and false if it is not.
