About this tool

Type or paste an IBAN, with or without spaces. The tool checks the country length and the mod-97 check digits, so it catches most typing mistakes. It does not confirm that the account exists.

How the check works

An IBAN starts with a country code and two check digits, followed by the national account number. To validate it the first four characters are moved to the end, letters become numbers (A is 10, B is 11 and so on), and the remainder when divided by 97 must be 1. Each country has a fixed length, for example 22 for Germany and the UK and 27 for France.

What it cannot do

A valid IBAN is correctly formed but may belong to a closed account. Always confirm payee details before sending money, and be careful with requests that change bank details.

Privacy

The check runs in your browser and nothing is sent.

計算示例

With the boxes at their starting values (IBAN: GB82 WEST 1234 5698 7654 32), the tool shows: Country code: GB; Length: 22; Expected length: 22; Grouped: GB82 WEST 1234 5698 7654 32; Result: Looks valid. Change any box to see your own numbers. The result updates as you type, and nothing leaves your browser.

獲得最佳結果的提示

在相信結果之前先檢查每一個輸入項，因為一個錯誤的數字就會改變整個答案。請使用工資單、賬單、證書或合同上的準確數字，並記下計算日期。稅率、門檻和規則會不時變化，因此對於稅費和法律事務，請將結果視為估算，並與本頁註明的官方來源核對。您可以嘗試任意多個方案；不會儲存或傳送任何內容，重新整理頁面會清空輸入。
