배송 조회 is a noun phrase meaning delivery tracking, shipment tracking, or tracking lookup.

• 배송 = delivery, shipping
• 조회 = inquiry, lookup, checking

So this sentence is talking about the tracking/checking process becoming faster, not the package itself moving faster.

Because 배송 조회 is a compound noun: two nouns joined together to make one idea.

This is very common in Korean:

• 배송 조회 = delivery tracking
• 회원 가입 = member registration
• 주문 번호 = order number

So you do not need a particle between the two nouns here.

Here, 배송 조회가 is the subject of the sentence.

The sentence is saying:

• 배송 조회가 = delivery tracking
• 점점 = gradually, more and more
• 빨라집니다 = becomes faster

So 가 marks the thing that is becoming faster.

A natural way to think of it is:

• Delivery tracking is getting faster.

점점 means gradually, little by little, or more and more.

It shows a progressive change over time.

Examples:

• 날씨가 점점 추워집니다. = The weather is getting colder and colder.
• 한국어가 점점 익숙해집니다. = Korean is becoming more and more familiar.

In your sentence, 점점 tells you that the speed is improving over time, not all at once.

Because 빨라집니다 means becomes fast / gets faster, while 빠릅니다 simply means is fast.

Compare:

• 배송 조회가 빠릅니다.
  = Delivery tracking is fast.

• 배송 조회가 점점 빨라집니다.
  = Delivery tracking is getting faster and faster.

So the sentence uses 빨라집니다 because it describes a change.

It comes from:

• 빠르다 = to be fast
• -아/어지다 = to become

So:

• 빠르다 → 빨라지다 = to become fast
• 빨라집니다 = formal polite form of 빨라지다

This change happens because 빠르다 is a 르-irregular adjective.

A simple learner-friendly breakdown is:

• dictionary form: 빠르다
• becoming form: 빨라지다
• formal polite present: 빨라집니다

-ㅂ니다 makes the sentence formal and polite.

So 빨라집니다 is the formal polite style often used in:

• announcements
• customer service messages
• business writing
• official notices

Less formal versions would be:

• 배송 조회가 점점 빨라져요. = polite casual
• 배송 조회가 점점 빨라져. = casual

Since this sentence sounds like something from a service notice or app message, -ㅂ니다 fits well.

Yes, you could. Both are possible, but the nuance is a little different.

• 배송 조회가 점점 빨라집니다.
  This simply presents delivery tracking as the thing that is getting faster.

• 배송 조회는 점점 빨라집니다.
  This makes delivery tracking the topic, and can sound slightly more contrastive or thematic, like:
  As for delivery tracking, it is getting faster.

In many cases, both are natural, but 가 is a very straightforward choice here.

Yes. 점점 더 빨라집니다 is also natural.

• 점점 빨라집니다 = gets faster and faster
• 점점 더 빨라집니다 = gets even faster / more and more faster

In practice, 점점 already contains the idea of increasing change, so 더 is often optional.

That means:

• 점점 빨라집니다 is perfectly natural
• 점점 더 빨라집니다 adds a bit more emphasis

Because 빨리 is an adverb meaning quickly, while 빨라지다 is the correct become + adjective form.

Compare:

• 빨리 = quickly
  
  • 배송 조회를 빨리 합니다. = I check tracking quickly.
• 빠르다 / 빨라지다 = to be fast / to become fast
  
  • 배송 조회가 빨라집니다. = Delivery tracking becomes faster.

So for becoming fast, you need 빨라지다, not 빨리지다.

No, not usually.

The sentence specifically says 배송 조회, which refers to the tracking/checking system. So it means something like:

• the tracking page loads faster
• tracking results appear faster
• tracking updates can be checked more quickly

If you wanted to say the actual delivery is getting faster, you would say something more like:

• 배송이 점점 빨라집니다.
  = Delivery is getting faster.

That is an important difference.
