Mã bưu chính và mã theo dõi ở đây.

Mã means code, number, or ID, depending on context.

In this sentence, it appears twice:

• mã bưu chính = postal code / ZIP code
• mã theo dõi = tracking code / tracking number

Vietnamese often uses mã for all kinds of coded identifiers, so it is a very useful word to know.

Bưu chính means postal or mail-related.

So:

• mã bưu chính literally = postal code

You may also hear other postal-related expressions with bưu chính in more formal Vietnamese. In everyday use, learners often just need to recognize that bưu chính relates to the postal system.

Mã theo dõi means tracking code or tracking number.

• theo dõi literally means to follow or to track
• so mã theo dõi is the code used to follow a shipment or package

Even though English often says tracking number, Vietnamese may still use mã, because the idea is an identifying code.

Và means and.

It joins the two noun phrases:

• mã bưu chính
• mã theo dõi

So the structure is simply:

• mã bưu chính và mã theo dõi = the postal code and the tracking code

Because là is usually not used for location in Vietnamese.

In English, we say:

• The postal code and tracking code are here.

But Vietnamese usually expresses location without là:

• Mã bưu chính và mã theo dõi ở đây.

Here, ở đây means here / in this place.

So this is a normal Vietnamese pattern:

• X ở đây = X is here

Using là here would sound unnatural.

Ở đây means here or at this place.

• ở = at / in
• đây = here / this place

Together, they form a location phrase:

• ở đây = here

So the sentence is saying that the postal code and tracking code are located here.

It is understandable as a full sentence, but it can feel a little short or label-like, depending on context.

For example, it sounds very natural if someone is pointing to a place on a screen, form, or document:

• Mã bưu chính và mã theo dõi ở đây. = The postal code and tracking code are here.

In conversation, Vietnamese often allows this kind of compact sentence.

A slightly different wording you might also see is:

• Đây là mã bưu chính và mã theo dõi. = Here are the postal code and tracking code.

That version uses đây là to present something, while the original uses ở đây to indicate location.

Vietnamese often puts the main noun first and then adds words that describe it.

So:

• mã bưu chính = code + postal
• mã theo dõi = code + tracking

This is different from English, where the describing word often comes first:

• postal code
• tracking code

So a useful pattern is:

• mã + description

Examples:

• mã số = number code / ID number
• mã giảm giá = discount code
• mã xác nhận = confirmation code

It refers to two items:

• one postal code
• one tracking code

Vietnamese nouns do not change form for singular or plural the way English nouns often do. The number is understood from context.

Here, the use of và makes it clear that two separate things are being mentioned.

Vietnamese does not have articles like the or a/an in the same way English does.

So:

• mã bưu chính can mean a postal code, the postal code, or just postal code
• the exact meaning depends on context

In this sentence, English naturally translates it with the because the listener probably already knows which postal code and tracking code are being referred to.

Sometimes yes, but the meaning or structure changes a little.

• ở đây clearly means here / in this place
• đây by itself can mean here, this, or can be part of a presentation structure like đây là...

Compare:

• Mã bưu chính và mã theo dõi ở đây. = The postal code and tracking code are here.

• Đây là mã bưu chính và mã theo dõi. = These/Here are the postal code and tracking code.

So ở đây emphasizes location, while đây là introduces or presents something.

It is a very common and understandable way to say it, especially in modern Vietnamese.

Depending on context, people might also say:

• số theo dõi = tracking number
• mã vận đơn = shipment / waybill code, in some delivery contexts

But mã theo dõi is clear and natural for learners to know.

A very natural English translation would be:

• The postal code and tracking number are here.
• Here are the postal code and tracking number.

The Vietnamese sentence keeps the nouns first and then gives the location:

• [postal code and tracking code] + [here]

That is a very common Vietnamese pattern.
