二、齊頭式(Blocked)
這種格式與全齊頭式相似，只是有些內容不是從空白處寫起。結尾敬辭、信末簽名、寫信人姓名和職銜都從中間寫起。日期可以從中間起行，也可以靠右對齊。
三、半齊頭式(semi-blocked)
這種格式與齊頭式雷同。不同的是，半齊頭式的每個段落縮進五或十個英文字母;結尾敬辭、信末簽名、寫信人姓名和職銜從中間寫起。

四、方齊頭式(square-blocked)
這種格式也類似於全齊頭式。不同的.是，它的日期靠右對齊，和收信人地址在同壹行。這種格式平整見方，外觀漂亮。
五、簡化式(simplified)
簡化時式和全齊頭式相比，有幾個主要的區別：首先，簡化式沒有稱呼和結尾敬語，收信人姓名必須在信文內的某個地方出現。其次，事由和寫信人姓名必須大寫。最後，列表要縮進五個英文字母空位，如果加有序號就不必縮進。
