Kroz aplikaciju zatražite prijenos broja.

Here kroz aplikaciju means through the app or via the app.

The preposition kroz literally often means through, especially in physical space, but it is also commonly used in a more abstract sense, like through/by means of/via something.

• kroz tunel = through the tunnel
• kroz razgovor = through conversation
• kroz aplikaciju = through/via the app

So in this sentence, it means that the request should be made using the application.

Because the preposition kroz takes the accusative case, and aplikacija changes in the accusative singular to aplikaciju.

• nominative: aplikacija
• accusative: aplikaciju

So:

• kroz aplikaciju = through the app

This is a standard case pattern in Croatian: certain prepositions require a specific case, and kroz requires the accusative.

Zatražite is the imperative form of the verb zatražiti, meaning to request or to ask for.

In this sentence, it means:

• request
• submit a request for

The form zatražite can be understood as:

• you (plural) request
• or a formal singular command, like please request

So in instructions, advertisements, websites, or customer service language, zatražite is very common because it sounds polite and direct.

Examples:

• Nazovite nas. = Call us.
• Pošaljite poruku. = Send a message.
• Zatražite prijenos broja. = Request number transfer.

Grammatically, it is the 2nd person plural imperative, but Croatian uses that same form for formal singular as well.

So zatražite can mean:

• you all request
• or request when speaking politely to one person

This is similar to how some languages use a plural form for politeness. In English, we usually just use you, so the difference is not visible.

If you were talking informally to one person, you would say:

• zatraži

So:

• informal singular: Zatraži prijenos broja.
• formal singular / plural: Zatražite prijenos broja.

Because zatražiti is a perfective verb, while tražiti is imperfective.

Very roughly:

• tražiti = to ask for, to seek, to be asking for
• zatražiti = to make a request, to request once / as a complete action

In instructions like this, Croatian often prefers the perfective verb because the focus is on completing the action.

So:

• Zatražite prijenos broja. = Submit/request the number transfer.

  This sounds natural for a one-time, goal-oriented action.

Prijenos broja means number transfer or more naturally number porting / transfer of your phone number.

It is made of:

• prijenos = transfer
• broja = of the number

This is a very common noun phrase in telecom contexts.

Because broja is in the genitive case.

The noun prijenos is followed here by a noun in the genitive to show what is being transferred:

• prijenos broja = transfer of the number

This is a very common pattern in Croatian:

• promjena adrese = change of address
• provjera stanja = checking of status/balance
• otkazivanje usluge = cancellation of the service

So broja is the genitive singular form of broj.

• nominative: broj
• genitive: broja

Yes, from the context it clearly means a phone number.

By itself, broj can mean:

• number
• telephone number
• a numeral
• a quantity, depending on context

But in the phrase prijenos broja, especially in telecom or mobile service language, it means phone number transfer.

A more explicit version would be something like:

• prijenos telefonskog broja

But Croatian often leaves telefonskog out because the meaning is obvious.

Croatian often leaves out possessive words like your when the meaning is obvious from context.

So:

• zatražite prijenos broja
  literally looks like request transfer of number

but naturally means:

• request the transfer of your number

In instructions aimed at the customer, it is understood that the number is the customer’s number, so adding vašeg is often unnecessary.

A fuller version could be:

• Zatražite prijenos svojeg broja.
• Zatražite prijenos vašeg broja.

But the shorter version is very normal in ads, apps, and instructions.

Yes. Croatian word order is more flexible than English word order, because case endings show grammatical relationships.

The original sentence:

• Kroz aplikaciju zatražite prijenos broja.

is natural because it emphasizes the method first: through the app.

You could also say:

• Zatražite prijenos broja kroz aplikaciju.

This also means the same thing and may sound slightly more neutral or straightforward.

So the choice of word order often depends on emphasis, style, and rhythm rather than strict grammatical necessity.

No. It is natural, but not the only option.

Other possibilities include:

• u aplikaciji = in the app
• putem aplikacije = by means of the app / via the app
• preko aplikacije = over/via the app

There can be slight differences in tone:

• kroz aplikaciju sounds very natural in marketing or user instructions
• putem aplikacije sounds a bit more formal
• u aplikaciji focuses more on location inside the app interface
• preko aplikacije is also common in everyday usage

So kroz aplikaciju is good and idiomatic, but not the only possible phrasing.

A very literal translation is:

• Through the app, request number transfer.

But more natural English would be:

• Request a number transfer through the app.
• Request the transfer of your number through the app.
• Use the app to request number transfer.
• Request number porting in the app.

In telecom English, number porting may be the most technical/natural term, but transfer of your number is often clearer for learners.

It is pronounced approximately like:

• zah-TRAH-zhee-teh

A few helpful points:

• ž sounds like the s in measure
• tr is pronounced clearly as a cluster
• the stress is not usually marked in normal writing, but for a learner, saying it smoothly as zah-TRAH-zhee-teh will be understandable

So:

• zatražite ≈ zah-TRAH-zhee-teh

Yes, absolutely. It sounds like standard Croatian instructional or promotional language.

It is short, direct, and polite, which is very typical for:

• app interfaces
• telecom websites
• advertisements
• customer service instructions

Croatian often uses the imperative in this kind of context, just like English uses phrases such as:

• Click here
• Enter your details
• Request transfer

So the sentence sounds natural and realistic.
