台灣人常因為各種因素改名。但是姓名乃是確認人别之重要依據，若改名過於頻繁，恐造成别人别辨識困難以及行政事務之困擾。
依姓名條例第9條第1項規定，得申請改名之情形，多與避免人别辨識混淆有關（例如：「在一機關、機構、團體或學校服務或肄業，姓名完全相同者」、「銓敘時發現姓名完全相同，經銓敘機關通知者」、與「與經通 案有案之人犯姓名完全相同者」等），若係因為避免混淆等因素改名者，法條無改名次數限制。
不過，依同條第2項之規定，如因命名文字字義粗俗不雅或有特原因而申請改名者，以三次為限。因此，如非為避免人别辨識混淆等因素，而是基於民間常見之算命改名等情而申請改名者，一人一生僅有三次機會。

In Taiwan, many people choose to change their names for various reasons. However, a person's name is an important way to identify them. Frequent name changes may cause confusion for others and create problems in administrative or legal processes.
According to Article 9, Paragraph 1 of the Name Act, many valid reasons for changing your name are related to avoiding confusion in identity. For example, you may apply to change your name if: "you have the exact surname as someone else at your workplace or school," "Your name is identical to someone else's during a service review and the review agency notifies you," "Your name is the same as that of a wanted criminal," In such cases, the law does not limit the number of time you can change your name.
However, according to Paragraph 2 of the same article, if you apply to change your name because the characters are rude, inappropriate, or due to other personal reasons, you are only allowed to do so up to three times in your lifetime. This means that if you're changing your name for reasons like fortune-telling, superstition, or personal preference, and not to avoid confusion with others, you only have three chances to do so.
