Трек-номер и код товара указаны правильно.

Because there are two separate things being talked about:

• трек-номер = tracking number
• код товара = product code

They are joined by и = and, so together they form a compound subject. In Russian, a compound subject with и normally takes a plural predicate:

• Трек-номер и код товара указаны... = The tracking number and the product code are indicated...

So even though each noun is singular by itself, the verb form is plural because the meaning is they.

Указаны is a short passive participle, plural form, from the verb указать.

In this sentence, it means something like:

• have been indicated
• are listed
• are specified

So the sentence is literally close to:

• The tracking number and the product code are indicated correctly.

This kind of form is very common in Russian for stating a result or condition.

Compare:

• Адрес указан правильно. = The address is indicated correctly.
• Данные указаны неверно. = The data are indicated incorrectly.

Because указали means they indicated and is a normal past-tense verb form with an implied subject like they.

But указаны does not mean they indicated. It means are indicated / have been indicated.

So:

• Они указали адрес. = They indicated the address.
• Адрес указан. = The address is indicated / has been indicated.

In your sentence, the focus is on the state of the information, not on who entered it.

Because правильно describes how the information is indicated, not what the nouns are like.

So:

• указаны правильно = indicated correctly

Here правильно is an adverb, modifying указаны.

If you said правильные, that would be an adjective describing the nouns themselves:

• правильные данные = correct data

But this sentence means:

• The tracking number and product code were entered/listed correctly,

not:

• The tracking number and product code are correct ones.

Because код товара means the code of the product or more naturally product code.

This is a very common Russian pattern:

• X + noun in the genitive = X of something

So:

• код товара = code of the product
• номер заказа = order number
• цена товара = price of the product
• цвет машины = color of the car

The base noun is код, and товара tells you what kind of code it is.

Russian usually does not use a present-tense form of to be in sentences like this.

In English:

• The tracking number and product code are indicated correctly.

In Russian, the equivalent present-tense is/are is normally omitted:

• Трек-номер и код товара указаны правильно.

This is completely normal.

You do see forms of быть in the past or future:

• были указаны = were indicated
• будут указаны = will be indicated

But in the present, Russian usually leaves is/are unstated.

Because и is simply connecting two items in one subject:

• трек-номер и код товара

This is just like English:

• the tracking number and the product code

No comma is needed when two nouns are joined by и in a simple list of two items.

A comma would only appear in other structures, not in this basic X and Y pattern.

Трек-номер is widely understood, especially in online shopping, delivery, and logistics. It is a borrowed, semi-colloquial modern term based on English track.

The hyphen is used because it is treated as a compound word.

However, depending on style, you may also see more native or formal alternatives, such as:

• номер отслеживания = tracking number
• sometimes номер для отслеживания

So:

• Трек-номер sounds natural in e-commerce/customer-service contexts.
• Номер отслеживания may sound more neutral or formal.

Yes. Russian word order is more flexible than English.

The neutral order here is:

• Трек-номер и код товара указаны правильно.

But you could also see:

• Правильно указаны трек-номер и код товара.
• Трек-номер и код товара правильно указаны.

These versions are all grammatical, but the emphasis changes slightly.

• указаны правильно sounds neutral and straightforward.
• Starting with правильно can emphasize correctly.
• Putting правильно before указаны can also shift the focus a little.

In most ordinary situations, the original sentence is the most natural.

Yes. Together they form the subject of the sentence, so both are in the nominative:

• трек-номер — nominative singular
• код — nominative singular

Inside код товара, only код is nominative. The word товара is genitive because it depends on код.

So the structure is:

• [Трек-номер] и [код товара] = compound subject
• указаны правильно = predicate

Usually, yes. In context, it often means that the tracking number and product code were:

• entered correctly
• provided correctly
• listed correctly
• specified correctly

Russian often uses указать in situations where English might use different verbs depending on context.

So in a website, order form, or customer-service message, this sentence could naturally mean:

• The tracking number and product code have been entered correctly.

Even though the literal idea is indicated/specified, the practical meaning often depends on the situation.

Normally, no. With X и Y, Russian usually uses the plural:

• Трек-номер и код товара указаны правильно.

Using singular here would sound ungrammatical in standard Russian.

Singular agreement can happen in some special constructions or with different conjunctions, but not in this ordinary noun + и + noun subject.

So for this sentence, указаны is the correct choice.
