實用性 > 各國 IBAN格式

此表格簡述各國之IBAN的格式：
於ISO兩位國家代碼之後的 kk 表示由IBAN其他字母計算而得的校對碼。假如目前有疑慮，將於 Comments 列中指出。此狀況存在於當 BBAN 之校對碼使用和 IBAN校對碼一樣的演算法。
BBAN列為IBAN中之BBAN部分的格式。大寫字母 (A–Z) 以 "a"表示，數字 (0–9) 以 "n" 表示，不分大小寫文數字 (a–z, A–Z, 0–9) 以 “c"。例如，保加利亞 BBAN (4a,6n,8c) 包含 4 大寫字母，接著為6數字，再來為 8 不分大小寫文數字。
將引入IBAN的國家列於 italics， 預計引入時間 ‘’'加粗。
