Questions & Answers about shímíngrènzhèng xūyào shēnfènzhèng.

What part of speech is 实名认证 here? Is it a verb or a noun?

It is best understood here as a noun-like phrase meaning the process of real-name verification.

In everyday Chinese, 实名认证 can behave a bit flexibly:

• as a set term / noun: real-name verification
• as a verb phrase: to complete real-name verification

In this sentence, 实名认证 comes before 需要, so it works like the thing being discussed:

• 实名认证需要身份证。
• literally: Real-name verification needs an ID card.

So even though it contains action-like meaning, in this sentence it functions more like a subject.

Why is there no word for you in this sentence?

Chinese often leaves out subjects when they are obvious or unimportant.

English usually says:

• You need an ID card for real-name verification.

Chinese can say:

• 实名认证需要身份证。

This does not sound incomplete in Chinese. The sentence focuses on the general requirement, not on who is doing it.

A natural way to think about it is:

• For real-name verification, an ID card is required.

So the idea of you is understood from context and does not need to be stated.
