Zonder track-en-tracecode kan niemand de bezorging volgen.

Zonder means without. Dutch often allows a prepositional phrase like this to come first in the sentence to set the context.

So:

• Zonder track-en-tracecode = Without a track-and-trace code
• then the main clause follows: kan niemand de bezorging volgen

Starting with Zonder... gives emphasis to the condition: if there is no code, then nobody can track the delivery.

This is because Dutch is a verb-second (V2) language in main clauses.

The first position is already taken by Zonder track-en-tracecode. Once something other than the subject comes first, the finite verb must come next.

So the structure is:

• Zonder track-en-tracecode = first position
• kan = second position
• niemand = subject
• de bezorging volgen = rest of the clause

Compare:

• Niemand kan de bezorging volgen. = Nobody can track the delivery.
• Zonder track-en-tracecode kan niemand de bezorging volgen. = Without a track-and-trace code, nobody can track the delivery.

Both are correct, but the word order changes because of the V2 rule.

Niemand means nobody / no one.

It is the Dutch indefinite pronoun used for people, just like English nobody or no one.

Examples:

• Niemand weet het. = Nobody knows it.
• Ik ken niemand hier. = I know nobody here / I don’t know anyone here.

In your sentence, niemand is the subject: the person who is unable to do the action.

Because the sentence uses the modal verb kan (can / is able to).

In Dutch, when a modal verb is the finite verb, the other verb usually goes to the end in its infinitive form.

So:

• kan = finite verb
• volgen = infinitive, placed at the end

This is very common in Dutch:

• Ik kan komen. = I can come.
• Zij wil eten. = She wants to eat.
• Wij moeten wachten. = We must wait.

So in your sentence:

• kan ... volgen = can track / can follow

Track-en-tracecode is a compound noun meaning track-and-trace code, the code used to follow a shipment or delivery.

Dutch very often joins nouns into one long compound word. Here, the borrowed English expression track and trace is combined with code.

The hyphens help show the internal structure:

• track-en-trace
  • code

This kind of spelling is common in Dutch when compounds contain foreign words or multi-part expressions.

De bezorging means the delivery or the delivery process. It focuses on the shipment as something being delivered, rather than on the physical package itself.

So there is a slight difference:

• het pakket volgen = track the package
• de bezorging volgen = track the delivery

In real-life Dutch, both kinds of phrasing can be used depending on what is being emphasized. De bezorging volgen sounds natural when talking about delivery status.

Also, bezorging is a de-word, so it takes de.

Here, kan means can / is able to, not may in the sense of permission.

So:

• kan niemand de bezorging volgen = nobody can track the delivery
• not nobody may track the delivery

The idea is about possibility or ability, because without the code, tracking is not possible.

After zonder (without), Dutch often uses a noun without an article when speaking generally.

So:

• zonder track-en-tracecode = without a track-and-trace code
• zonder jas = without a coat
• zonder reden = without reason

You could sometimes see an article in other contexts if a very specific item is meant, but in this sentence the article-less form is the natural general expression.

Yes, a comma is possible:

• Zonder track-en-tracecode, kan niemand de bezorging volgen.

But in Dutch, a short introductory phrase like this is often written without a comma, especially in everyday writing.

So the version without the comma is completely normal.
