This IBAN checker validates the format of an International Bank Account Number (IBAN) and up to 4000 IBANs can be checked at any one time.
This tool does not verify if the account exists or that the IBAN belongs to your beneficiary.
Additional checks are also applied to only dutch bank account numbers, so called "elfproef".
The IBAN uniquely identifies an account held at a bank. An IBAN is not replacing the national numbering systems and is also not a new bank account number. It is a way of representing national account numbers in an internationally recognised standard format.
The IBAN (=identifies an account) is always used in conjunction with a Bank Identifier Code (BIC) (=identifies your bank) and together they are used on all cross-border payments within the European Union (EU)/European Economic Area (EEA). Failure to provide both information results in higher processing fees or payment being delayed or rejected. In the EU, banks are required to provide the IBAN and BIC to their customers.
If you are paying from outside the EU zone (e.g. USA) to a beneficiary in the EU zone (e.g. Netherlands) then always enter both IBAN and BIC number in your payment form.
If you are paying from inside the EU zone (e.g. Netherlands) to a beneficiary outside the EU zone (e.g. USA) then it is unlikely that the payer's country bank will use the IBAN system since IBAN is used within europe and few other countries.
Payment form example:
When an IBAN is printed in paper form, see example above, the IBAN may be split into groups of four characters to make it easier to read. When an IBAN is processed electronically it must not contain blank spaces and must not include the word 'IBAN'.
Paper form: NL91 ABNA 0417 1643 00
Electronic form: NL91ABNA0417164300
The IBAN is a series of alphanumeric characters [0-9A-Z] and starts with a 2 character country code (ISO 3166), followed by a 2-digit checksum and the Basic Bank Account Number (BBAN, ISO 13616). The BBAN itself consists of a bank/branch code and the account number, both with optional check digits. An IBAN number is limited to a maximum of 34 contiguous alphanumeric characters. How to calculate and validate the two digit checksum can be found in the document IBAN: INTERNATIONAL BANK ACCOUNT NUMBER issued by European Payment Counsil (EPC)
The IBAN exact structure is country specific: Note: France also includes French Guyana (GF), French Polynesia (PF), French Southern Territories (TF), Guadeloupe (GP), Martinique (MQ), Mayotte (YT), New Caledonia (NC), Reunion (RE), Saint Barthelemy (BL), Saint Martin (French part) (MF), Saint Pierre et Miquelon (PM), Wallis and Futuna Islands (WF).
This IBAN checker is based on the technical specification as described in the IBAN Registry (Release 66 - May 2016) in PDF format or IBAN Registry (Release 66 - May 2016) in txt format. Both documents were taken from the SWIFT website.
