Los datos de la tarjeta incluyen el código CVV.

Because dato is a masculine noun in Spanish, so its plural is los datos.

• singular: el dato
• plural: los datos

Even though data in English can sound abstract or collective, in Spanish dato is a normal countable noun meaning piece of information, detail, or data item.

In this sentence, datos means something like details or information.

So los datos de la tarjeta means the card details or the information on/from the card.

Depending on context, datos can mean:

• data
• details
• information
• personal details

Here, because the sentence is about a bank/payment card, card details is the most natural idea.

Spanish usually expresses this kind of relationship with de rather than an apostrophe structure.

So:

• los datos de la tarjeta = the card details
• literally: the details of the card

This is very common in Spanish. English often prefers ’s or a noun used like an adjective, but Spanish normally uses de:

• el número de teléfono = the phone number
• la puerta de la casa = the house door / the door of the house

Because the subject is los datos, which is plural.

The verb incluir must agree with its subject:

• el dato incluye = the detail includes
• los datos incluyen = the details include

So in the sentence:

• Los datos de la tarjeta incluyen...

the verb is plural because datos is plural.

Because los datos are the thing doing the including, and el código CVV is just one of the things included.

So the structure is:

• Los datos = plural subject
• incluyen = plural verb
• el código CVV = singular object

That is completely normal:

• Los documentos incluyen una foto.
• The documents include a photo.

A plural subject can include one singular item.

Because código is a masculine singular noun:

• el código
• los códigos

The article agrees with código, not with CVV.

So el código CVV means the CVV code.
Even though CVV is an abbreviation, the gender comes from the main noun código.

People usually keep CVV as the abbreviation, especially in banking or online payment contexts.

In Spanish, you may also see similar terms like:

• código CVV
• código de seguridad
• código de verificación

But CVV itself is commonly left as CVV.

Yes, but details is usually more natural in this context.

• Los datos de la tarjeta = the card details
• The card data is possible in English, but less natural in everyday use

So while datos can mean data, in a sentence about payment cards it often corresponds better to details or information.

In this sentence, de la tarjeta sounds natural because it refers to a specific card or the card being discussed.

• los datos de la tarjeta = the card’s details / the details of the card

If you said de tarjeta on its own, it would usually sound incomplete or unnatural here.

Spanish often uses the definite article where English might be less explicit:

• el número de la cuenta
• la fecha de la compra
• los datos de la tarjeta

The structure is:

• Los datos de la tarjeta = subject
• incluyen = verb
• el código CVV = direct object

So it follows a normal subject + verb + object pattern:

Los datos de la tarjeta incluyen el código CVV.

This is one reason the sentence is fairly straightforward for English speakers.

It is possible in some contexts to omit an article in Spanish, but here el código CVV is the most standard and natural form.

Using el makes it clear that you mean the CVV code as a specific item among the card details.

So:

• incluyen el código CVV = the most natural choice here

Without the article, it may sound less complete or less idiomatic in a basic instructional sentence.

In Spain, the letters would normally be read individually in Spanish, so CVV would be pronounced:

• ce uve uve

That said, in real life people may also simply refer to it as:

• el CVV
• el código de seguridad

depending on the situation.

Yes. Tarjeta is a general word for card, and the exact meaning depends on context.

It can mean:

• bank card
• credit card
• debit card
• ID-style card
• membership card

In this sentence, because of código CVV, it clearly refers to a payment card such as a credit or debit card.
