In this sentence, 에 marks the target or destination of the inquiry: to the logistics center.

So 물류 센터에 문의했습니다 means I made an inquiry to the logistics center.

With verbs like 문의하다 (to inquire / to contact for information), 에 is commonly used to show the place, organization, or person you direct the inquiry to.

• 회사에 문의했어요 = I inquired with the company.
• 고객센터에 문의했습니다 = I contacted customer service.

재배송 is made of:

• 재- = again, re-
• 배송 = delivery, shipping

So 재배송 means redelivery or reshipment, depending on the situation.

In everyday usage, it usually refers to sending something again because the first delivery failed, was missing, was damaged, or had some other problem.

을/를 marks the direct object of the verb.

Here, the verb is 문의했습니다 (inquired / asked about), and the thing being asked about is 재배송.

So:

• 재배송을 문의했습니다 = I inquired about redelivery.

The structure is basically:

• A에 B를 문의하다
• inquire to A about B

So:

• 물류 센터에 = to the logistics center
• 재배송을 = about redelivery
• 문의했습니다 = inquired

All of them relate to asking, but they are used differently.

• 묻다 / 물어보다 = to ask
  This is the general everyday verb for asking a question.
• 문의하다 = to inquire, to make an inquiry
  This sounds more formal, businesslike, or customer-service-related.

So in a situation involving shipping, a company, or a service center, 문의하다 sounds much more natural than 묻다.

Compare:

• 친구에게 물어봤어요. = I asked my friend.
• 고객센터에 문의했어요. = I contacted customer service / made an inquiry to customer service.

Both are grammatically correct, but the level of politeness is different.

• 문의했습니다 = formal polite style
• 문의했어요 = standard polite style

Because 문의하다 often appears in business, customer-service, or formal situations, 문의했습니다 sounds very natural here.

So the sentence has a slightly formal tone, like something you might say in a workplace, customer support context, or written message.

Yes, 물류 센터 is commonly written with a space because it is a noun phrase made up of:

• 물류 = logistics
• 센터 = center

So 물류 센터 = logistics center

In real-world usage, spacing can sometimes vary in signs, company names, or casual writing, but 물류 센터 with a space is standard and natural.

The structure is:

물류 센터에 + 재배송을 + 문의했습니다

Which breaks down as:

• 물류 센터에 = to the logistics center
• 재배송을 = redelivery / about redelivery
• 문의했습니다 = inquired

So the order is:

[place/person asked] + [thing asked about] + verb

This is very normal Korean word order. Since Korean is an SOV language, the verb comes at the end.

Yes, the subject is omitted, which is very common in Korean.

English usually requires the subject:

• I inquired about redelivery with the logistics center.

Korean often leaves it out when it is obvious from context:

• 물류 센터에 재배송을 문의했습니다.

Depending on the situation, the implied subject could be:

• I
• we
• sometimes even another understood person

Korean frequently drops subjects and objects when they are already understood.

It can overlap with all of those in translation, depending on context.

Most literally, 문의했습니다 means:

• inquired
• made an inquiry

But in natural English, you might also translate it as:

• I contacted the logistics center about redelivery.
• I asked the logistics center about redelivery.

So the Korean has a slightly formal nuance, even if the best English translation might sound simpler.

Not exactly. 문의했습니다 means I asked about it or I contacted them regarding it, not necessarily that I formally requested it.

If you want to clearly say I requested redelivery, Korean would more naturally use something like:

• 재배송을 요청했습니다. = I requested redelivery.
• 재배송을 신청했습니다. = I applied for/requested redelivery.

So 문의했습니다 focuses on the inquiry, not the request itself.

Because the logistics center is not the thing being inquired about; it is the target of the inquiry.

• 에 marks where the inquiry is directed.
• 을/를 marks what is being inquired about.

So in this sentence:

• 물류 센터에 = to the logistics center
• 재배송을 = about redelivery

Using 물류 센터를 문의했습니다 would sound wrong because it would suggest the logistics center itself is the object of inquiry.

A more casual polite version would be:

• 물류 센터에 재배송을 문의했어요.

In even more conversational Korean, people might say something a little less formal, such as:

• 물류 센터에 재배송 관련해서 물어봤어요.
• 물류 센터에 재배송에 대해 물어봤어요.

These sound more like everyday spoken Korean, while 문의했습니다 sounds a bit more formal or businesslike.
