Why is John Doe used as a code name for unknown John Doe?

1, no, the word anonymous is used to refer to unidentified women, only women.

2. Origin of the word:

During the reign of Edward III in England, two names were invented in the process of discussing expulsion law at that time.

One is the anonymous landlord, and the other is Richard Rowe, the tenant.

This can explain the legal relationship between them more conveniently.

Later, Anonymous and Richard Rowe were used as appellations of anonymous parties in litigation, just like we said "Li" and "Zhang".

At the scene of the murder, when the identity of the deceased has not been confirmed, it is also called anonymous, and the female is called anonymous.

3. Scope of words: John Doe is widely used in the United States and Canada. Not all countries are universal.

Extended information Jane Doe originally originated in Britain. Some people say that this word comes from Edward III in14th century, while others say that it is now17th century. No matter what era, the story is the same-a landlord rented his land to the poor who had nothing to farm. Unexpectedly, this guy quietly ungrateful, took the landlord's entire industry, but also the landlord's family out of their own land.

The landlord angrily sued the guy who bite the hand that feeds him. The law at that time was almost a little bigger than it is now. Not direct investigation, but deduction first. In the interpretation, the court invented a lessor named Jane Doe, and the lessee was Richard Rowe.

I don't know the outcome of the lawsuit, but John Doe hasn't disappeared. This word stands for anonymity and those who cannot be named. Later, Jane doe was developed to represent women, because John and Jane are the most commonly used names in Britain.

In fact, Anonymous and Jane Doe are equivalent to Zhang San, Li Si, Wang Wu and Liu Zhao in Chinese. However, these two words originated in Britain are basically not used in Britain, and the United States and Canada use them the most.
