Questions & Answers about banpumeneun jumun beonhoga piryohapnida.

Why is 에는 attached to 반품 here?

에는 is 에 + 는.

• 에 can mark a context, situation, or “in/for” meaning.
• 는 adds topic or contrast.

So 반품에는 means something like:

• for returns
• when it comes to returns
• as for returns

It gives the sentence a slightly topical sense: In the case of returns, an order number is needed.

Without 는, 반품에 주문 번호가 필요합니다 is also possible, but 에는 sounds a bit more like setting up the topic or emphasizing that this requirement applies to returns.

Why is it 주문 번호가 필요합니다 and not 주문 번호를 필요합니다?

This is a very common Korean pattern.

With 필요하다 (to be necessary / to be needed), the thing that is needed is usually marked with 이/가, not 을/를.

So:

• 주문 번호가 필요합니다 = An order number is necessary / needed

Korean treats 필요하다 more like to be necessary than to need.

A helpful way to think about it is:

• English: We need an order number
• Korean: An order number is necessary

That is why 주문 번호가 sounds natural here.
