Yes. 운송장 번호 is the number written on a shipping waybill or shipping label, and in everyday use it usually corresponds to what English speakers call a tracking number.

• 운송장 = shipping invoice / waybill / shipping label
• 번호 = number

So 운송장 번호 is a noun phrase meaning the waybill number / tracking number.

Here, 로 means by / with / using. It shows the means or tool used to do something.

So 운송장 번호로 means:

• using the tracking number
• by the tracking number
• more naturally in English, with the tracking number

It tells you what was used to perform the shipping lookup.

배송 조회 is a compound noun made of:

• 배송 = delivery / shipment
• 조회 = inquiry / lookup / search

Together, 배송 조회 means something like:

• shipment tracking
• delivery lookup
• tracking inquiry

Korean often combines nouns like this to make technical or administrative expressions. There does not need to be a particle between them because they are functioning as one combined noun.

Because the whole object is 배송 조회, and the final noun in that compound is 조회.

So the structure is:

• 운송장 번호로 = using the tracking number
• 배송 조회를 = shipment tracking / delivery lookup + object marker
• 했습니다 = did

In other words, 배송 조회 acts as one noun phrase, and 를 marks that whole phrase as the object of 하다.

This is a very common Korean pattern: noun + 하다.

Here:

• 조회 is a noun meaning lookup / inquiry
• 조회하다 or 조회(를) 하다 means to look up / to inquire

Korean uses this pattern a lot, especially with Sino-Korean nouns in formal, business, and service-related language.

So 배송 조회를 했습니다 is a natural formal expression meaning did a shipment lookup / checked the delivery status.

Yes, that is possible in many contexts.

Both patterns are common:

• 조회했습니다
• 조회를 했습니다

They mean essentially the same thing. The version with 를 하다 can sound a little more explicitly noun-based, while 조회하다 feels slightly more compact. In formal or service language, both are very natural.

했습니다 is the polite formal past form of 하다.

It shows:

• past tense: the action was completed
• formal/polite style: appropriate for customer service, workplace language, announcements, and neutral polite conversation

So this sentence sounds like a polite statement such as one you might hear from customer support or read in a service message.

Because Korean often omits the subject when it is obvious from context.

So 운송장 번호로 배송 조회를 했습니다 does not explicitly say:

• I checked
• we checked
• someone checked

The subject is understood from the situation. In a customer-service context, it might mean we checked it using the tracking number. In personal speech, it could mean I checked it using the tracking number.

For this meaning, 로 is the most natural choice because it expresses the means used to do the lookup.

• 운송장 번호로 = using the tracking number

Other particles would change the meaning:

• 운송장 번호를 would make tracking number the direct object
• 운송장 번호에 would sound like at/on the tracking number, which does not fit well here
• 운송장 번호로는 adds contrast, like as for using the tracking number...

So for using the tracking number to check, 로 is the correct and natural particle.

The given order is very natural:

• 운송장 번호로 = by using the tracking number
• 배송 조회를 = shipment tracking
• 했습니다 = did

Korean usually places the verb at the end, and information like tools, methods, time, or place comes before the object and verb.

Some rearrangement is possible in Korean, but this version is standard and clear. For a learner, it is best to think of it as:

[means] + [object] + [verb]

It sounds natural, but somewhat formal or service-oriented.

That is because words like 운송장, 조회, and the ending 했습니다 are common in:

• customer service
• delivery apps or websites
• business communication
• official or written language

In casual everyday speech, someone might say something simpler depending on context, but this sentence is completely natural and common in delivery/tracking situations.
