세상에는 is made of:

• 세상 = the world
• 에 = in / at
• 는 = topic marker

So 세상에는 literally means something like in the world, as for... or when it comes to the world...

Here, 는 adds a topic or slight contrast feeling. It can sound like:

• In the world, there are...
• As for the world, there are...
• Out in the world, there are...

In many sentences, 에는 gives a natural background-setting feeling.

This is a very common question.

Korean usually uses:

• 에 with 있다 / 없다 for existence or location
• 에서 for where an action happens

Because 있습니다 means exist / there is / there are, the place where something exists is marked with 에.

So:

• 세상에는 여러 배송 회사가 있습니다.
  = There are several delivery companies in the world.

But with an action verb, you would often use 에서:

• 회사에서 일합니다.
  = I work at a company.

So the short rule is:

• existence → 에
• action → 에서

여러 means several, various, or a number of.

In this sentence, it tells you there is more than one delivery company.

Examples:

• 여러 사람 = several people
• 여러 나라 = various countries
• 여러 배송 회사 = several delivery companies

It is very natural and common before a noun.

Because Korean often does not mark plural when the meaning is already clear.

Here, 여러 already tells us there are multiple companies, so 회사들 is unnecessary.

Compare:

• 여러 회사가 있습니다. = There are several companies.
• 여러 회사들이 있습니다. = Also understandable, but usually less natural here

In Korean, plural marking with 들 is often optional, especially when a word like 여러, 많은, or a number already shows plurality.

In existence sentences, Korean often uses this pattern:

• 장소에/에는 + noun + 가 있다/없다

So:

• 세상에는 = in the world
• 여러 배송 회사가 = several delivery companies
• 있습니다 = exist / there are

The 가 marks what exists.

This is a very standard structure:

• 방에 사람이 있습니다. = There is a person in the room.
• 도시에 공원이 많습니다. = There are many parks in the city.
• 세상에는 여러 배송 회사가 있습니다. = There are several delivery companies in the world.

있습니다 is the formal polite form of 있다.

In this sentence, 있다 means to exist or to be present, so the whole sentence means something like:

• There are several delivery companies in the world.

Korean often uses 있다 where English uses there is / there are.

For example:

• 책이 있습니다. = There is a book. / I have a book.
  (depending on context)
• 문제가 있습니다. = There is a problem.
• 회사가 있습니다. = There is a company. / There are companies.

Here it clearly has the there are meaning.

Both are polite, but they differ in formality:

• 있어요 = polite, everyday speech
• 있습니다 = more formal, more official, more textbook/news/business style

So:

• 세상에는 여러 배송 회사가 있어요.
  = natural in conversation
• 세상에는 여러 배송 회사가 있습니다.
  = more formal or neutral-written style

The meaning is basically the same.

It is made of:

• 배송 = delivery / shipping
• 회사 = company

So 배송 회사 literally means delivery company or shipping company.

For learners, the important thing is to recognize it as a noun phrase meaning a company related to delivery services.

Even if you focus only on meaning, it helps to see the structure:

• 배송 describes the kind of 회사
• so it is literally a delivery company

They are similar, but not always exactly the same.

• 배송 is a broader word meaning delivery or shipping
• 택배 usually refers more specifically to parcel delivery / courier service

So:

• 배송 회사 can sound broader, like a company involved in delivery/shipping
• 택배 회사 often sounds more specifically like a courier or parcel-delivery company

In many everyday situations, though, learners may see both used in similar contexts.

The sentence follows a very common Korean pattern:

• 장소에는 + 무엇이 + 있습니다
• In/As for [place], [thing] exists

So here:

• 세상에는 = in the world
• 여러 배송 회사가 = several delivery companies
• 있습니다 = exist / there are

A very literal breakdown would be:

• As for in the world, several delivery companies exist.

More natural English:

• There are several delivery companies in the world.

It can sound natural, but it is a little broader and more general than just naming a specific place.

세상 means the world, so 세상에는 gives a wide, general sense like:

• in the world
• in the world out there
• in society / in the world at large

Depending on context, it may sound slightly broad, explanatory, or reflective. It is not necessarily poetic, but it is less concrete than something like:

• 한국에는 = in Korea
• 이 지역에는 = in this area

So this sentence feels like a general statement about the world.

Not exactly.

여러 usually means several or various, not necessarily many.

So the closer translations are:

• There are several delivery companies in the world.
• There are various delivery companies in the world.

If Korean wanted to emphasize many, it would more likely use:

• 많은 배송 회사가 있습니다. = There are many delivery companies.

So 여러 suggests plurality, but not necessarily a large quantity.

Yes — that is an excellent way to learn it.

This sentence is a textbook example of:

• X에는 Y가 있다 = In X, there is/are Y

Here:

• X = 세상
• Y = 여러 배송 회사

So:

• 세상에는 여러 배송 회사가 있습니다.

If you learn this pattern, you can make many similar sentences:

• 도시에는 큰 건물이 있습니다.
  = There are tall buildings in the city.
• 인터넷에는 많은 정보가 있습니다.
  = There is a lot of information on the internet.
• 학교에는 학생들이 있습니다.
  = There are students at the school.

This is one of the most useful Korean sentence patterns for beginners.
