La carátula de la póliza muestra el número de póliza.

Here carátula means the cover page, front page, or in insurance contexts often the declarations page of the policy.

In everyday Spanish, carátula can also mean things like:

• the cover of a book or CD
• a title page
• sometimes a faceplate or front panel, depending on context

In insurance Spanish in Latin America, it often refers to the page that summarizes key policy information.

Spanish often uses de where English might use apostrophe 's or a noun used like an adjective.

So:

• la carátula de la póliza = the policy's cover page
• literally: the cover page of the policy

This is a very common Spanish structure:

• el número de teléfono = phone number
• la fecha del contrato = the contract's date / the date of the contract

Because the sentence contains two different phrases:

• la carátula de la póliza = the cover page of the policy
• el número de póliza = the policy number

Even though English might try to avoid repetition, Spanish often repeats the noun naturally, especially in formal, legal, or administrative language. In this kind of document language, repeating póliza sounds normal and clear.

Número de póliza works a lot like a fixed label or category, similar to policy number in English.

So:

• el número de póliza = the policy number

This is common when Spanish is naming a type of number or document field:

• número de cuenta = account number
• número de serie = serial number
• número de pasaporte = passport number

If you say el número de la póliza, it can still be understood, but it sounds more like the number belonging to the policy rather than the standard document label policy number.

Muestra here is the third-person singular present tense of mostrar, meaning to show.

So it can mean:

• he/she shows
• it shows
• you show in formal usted

In this sentence, the subject is la carátula de la póliza, which is singular, so the verb is singular too:

• La carátula ... muestra ...
• The cover page ... shows ...

The subject is La carátula de la póliza.

That whole noun phrase acts as one unit:

• main noun: carátula
• extra information: de la póliza

So the sentence structure is:

• La carátula de la póliza = subject
• muestra = verb
• el número de póliza = direct object

A good way to check is to ask: What shows the policy number? Answer: The policy cover page.

Not here.

The verb mostrar means to show, to display, or to indicate.

Be careful because muestra can also be a noun:

• una muestra = a sample

But in this sentence, it is clearly a verb because it comes after the subject and before the object:

• La carátula ... muestra el número ...
• The cover page shows the number ...

The written accents show where the stress goes:

• carátula → stress on rá
• póliza → stress on pó
• número → stress on nú

These words are all esdrújulas in Spanish, meaning the stress falls on the third-to-last syllable. Words of that type always carry a written accent.

No. Other words may appear depending on the country and context, such as:

• portada
• cubierta
• hoja de declaraciones
• página de declaraciones

But in insurance language in much of Latin America, carátula is common and natural. It may refer specifically to the page with the main policy details, not just a decorative cover.

Because the sentence contains two separate de phrases, and each one has a different job:

• la carátula de la póliza = the cover page of the policy
• el número de póliza = the policy number

Spanish uses de very often to connect nouns. Even if it feels repetitive to an English speaker, it is completely normal Spanish.

Yes, but the original sentence is clear and natural, especially in formal writing.

For example, you could also say:

• El número de póliza aparece en la carátula de la póliza.
• En la carátula de la póliza aparece el número de póliza.

Those versions shift the focus slightly:

• the original emphasizes the cover page
• the alternatives emphasize the policy number or where it appears

All are grammatical, but the original sounds very standard for document-style language.
