Ez a kézbesítési cím.

Because Hungarian often omits the verb van = is in the present tense, third person when the predicate is a noun or adjective.

So:

• Ez a kézbesítési cím. = This is the delivery address.
• literally, it looks like This the delivery address.

This is completely normal Hungarian.

You would use van in other situations, for example:

• past: Ez volt a kézbesítési cím. = This was the delivery address.
• future: Ez lesz a kézbesítési cím. = This will be the delivery address.
• location/existence: A cím itt van. = The address is here.

So yes, Ez a kézbesítési cím is a full, natural sentence.

In Hungarian, when this or that directly modifies a noun, it normally appears together with the definite article:

• ez a cím = this address
• az a ház = that house

So ez a kézbesítési cím is the standard way to say this delivery address.

A useful way to think of it is:

• ez = this
• a = the
• together: ez a ... = this ...

If there is no noun after it, then ez can stand alone:

• Ez. = This.
• Ez a cím. = This is the address.

Also, the article changes to az before a vowel sound:

• ez az épület = this building

But here the next word is kézbesítési, which starts with a consonant sound, so it is a.

Kézbesítési means delivery-related or for delivery.

It comes from:

• kézbesít = to deliver
• kézbesítés = delivery
• kézbesítési = delivery-related, used as an adjective

The ending -i is a very common Hungarian way to make an adjective from a noun.

So:

• kézbesítés = delivery
• kézbesítési cím = delivery address

This is similar to how Hungarian forms many descriptive adjectives:

• iskola = school → iskolai = school-related
• Budapest → budapesti = from Budapest / Budapest-related

Because this already makes the noun phrase definite.

• Ez a kézbesítési cím. = This is the delivery address.

You would use egy if you meant a/an in a more general, classificatory sense:

• Ez egy kézbesítési cím. = This is a delivery address.

That version sounds more like you are identifying what kind of thing it is, not pointing out one specific known address.

So:

• ez a ... = this specific ...
• egy ... = a/an ...

Yes. This is the most neutral, natural word order for this meaning.

Structure:

• Ez = this
• a kézbesítési cím = the delivery address

So the sentence is basically:

• This the delivery address.

Hungarian word order is flexible, but different orders add emphasis or contrast. For example:

• A kézbesítési cím ez.

This is possible, but it sounds more marked, as if you are contrasting it with something else, like:

• The delivery address is this one.

For a plain statement, Ez a kézbesítési cím is the form learners should use.

A rough pronunciation guide is:

• Ez ≈ ez
• a ≈ short aw
• kézbesítési ≈ kayz-beh-shee-tay-shee
• cím ≈ tseem

A more accurate breakdown:

• é is a long ay
• í is a long ee
• s is pronounced like English sh
• c is pronounced like ts

So:

• kézbesítési has sh sounds where you see s
• cím begins with ts, not with English k or s

Approximate IPA:

• Ez a kézbesítési cím. → [ɛz ɒ keːzbɛʃiːteːʃi t͡siːm]

Also, Hungarian stress is normally on the first syllable of each word:

• EZ a KÉZbesítési CÍM

It means a delivery address, usually the address where something should be sent or delivered.

Depending on context, in English this may be translated as:

• delivery address
• shipping address
• sometimes mailing address

It is often contrasted with:

• számlázási cím = billing address

So if you see:

• Ez a kézbesítési cím.

the idea is that this is the address for delivery, not necessarily the billing address or some other address.

Cím is singular here, and it is in the nominative form, which is the basic dictionary form.

So:

• cím = address

No extra ending is added because it is the subject/predicate form in this sentence.

If the word changed case, it would look different, for example:

• címet = address, as a direct object
• címen = on the address / under the address
• címre = to the address

But in Ez a kézbesítési cím, the basic form cím is exactly what you expect.
