IBAN and Routing Number Lookup API vs IBAN Validator API: What to Choose?

In the world of financial transactions, ensuring the accuracy of banking information is paramount. Two powerful tools that assist developers in validating and retrieving banking data are the IBAN and Routing Number Lookup API and the IBAN Validator API. This blog post will provide a comprehensive comparison of these two APIs, focusing on their features, use cases, performance, and overall value to developers.

Overview of Both APIs

The IBAN and Routing Number Lookup API is designed to provide access to critical information related to SWIFT codes, IBAN codes, and Routing Bank Numbers. It streamlines financial transactions by verifying the accuracy of banking information quickly and efficiently. Key features include the Routing Bank Checker, IBAN Code Checker, and SWIFT Code Checker, each serving a unique purpose in validating banking information.

On the other hand, the IBAN Validator API specializes in validating any bank account information, including IBAN, BIC/SWIFT, and BBAN. This API is particularly useful for developers who need to ensure that bank account details are accurate before processing transactions. Its primary feature, the Iban Check, allows users to validate IBAN codes and retrieve relevant banking information.

IBAN and Routing Number Lookup API Features

The IBAN and Routing Number Lookup API offers several key features:

Routing Bank Checker

This feature allows users to pass in a routing number and receive detailed information about the corresponding bank. The response includes the bank's name, address, and contact information, ensuring that developers can verify the legitimacy of the routing number.

{"status":200,"success":true,"message":"Routing Bank 031101334 is valid","data":{"routing_number":"031101334","date_of_revision":"Jan 5, 2023","new_routing_number":"","bank":"Sofi Bank, National Association","address":"San Francisco, CA","city":"San Francisco","state":"CA","zip":"","phone":"855-936-2269"}}

In this response, the routing_number field confirms the routing number checked, while bank provides the name of the bank associated with that routing number. The address field gives the physical location of the bank, which can be crucial for compliance and verification processes.

IBAN Code Checker

This feature allows users to validate any IBAN code and retrieve relevant information about the bank associated with that IBAN. The response includes details such as the country, account number, and bank code.

{"status":200,"success":true,"message":"PT50000101231234567890192 is a valid IBAN","data":{"iban":"PT50000101231234567890192","country":"Portugal [PT]","sepa_country":"Yes","checksum":"50","bban":"000101231234567890192","bank_code":"0001","branch_code":"0123","account_number":"12345678901"}}

In this response, the iban field confirms the IBAN checked, while country indicates the country of the bank. The checksum field is essential for validating the integrity of the IBAN, and the account_number field provides the actual account number for transactions.

SWIFT Code Checker

This feature allows users to validate a SWIFT code and receive additional data from the bank. The response includes the bank's name, location, and branch information.

{"status":200,"success":true,"message":"SWIFT code EWBKHKHH is valid","data":{"swift_code":"EWBKHKHH","bank":"EAST WEST BANK","city":"Central","branch":null,"address":"FINANCE STREET, 8, TWO INTERNATIONAL FINANCE CENTRE, FLOOR 11, SUITE 1108","post_code":null,"country":"Hong Kong","country_code":"HK","breakdown":{"swift_code":"EWBKHKHH or EWBKHKHHXXX","bank_code":"EWBK - code assigned to EAST WEST BANK","country_code":"HK - code belongs to Hong Kong","location_code":"HH - code represents the institution location","code_status":null,"branch_code":"XXX - code indicates this is a branch office"}}}

The swift_code field confirms the SWIFT code checked, while bank provides the name of the bank. The address field gives the physical location of the bank, which is essential for international transactions.

IBAN Validator API Features

The IBAN Validator API focuses on validating bank account information with the following key feature:
