一維碼ITF 25又稱交插25條碼，常用在序號(hào)，外箱編號(hào)等應(yīng)用。交插25碼是一種條和空都表示信息的條碼，交插25碼有兩種單元寬度，每一個(gè)條碼字符由五個(gè)單元組成，其中二個(gè)寬單元，三個(gè)窄單元。在一個(gè)交插25碼符號(hào)中，組成條碼符號(hào)的字符個(gè)數(shù)為偶數(shù)，當(dāng)字符是奇數(shù)個(gè)時(shí)，應(yīng)在左側(cè)補(bǔ)0變?yōu)榕紨?shù)。條碼字符從左到右，奇數(shù)位置字符用條表示，偶數(shù)位字符用空表示。交插25碼的字符集包括數(shù)字0到9.
