Chủ thẻ mang giấy tờ tùy thân để cấp lại thẻ.

Chủ thẻ literally means card owner or cardholder.

• chủ = owner, holder, person in charge
• thẻ = card

So chủ thẻ is the person whose card it is. In official or administrative Vietnamese, this is a very common way to refer to the person who uses or legally holds the card.

Vietnamese often leaves out things that English requires.

In this sentence:

• chủ thẻ can mean the cardholder or cardholders, depending on context
• there is no article like the or a
• there is also no explicit must, but in official notices it is often understood

So in context, the sentence can naturally mean something like:

• The cardholder brings identification documents to have the card reissued
• or more naturally in English: The cardholder must bring identification documents for card reissuance

Vietnamese administrative language often sounds more compressed than English.

Mang means to bring or to carry.

In this sentence, it means the cardholder should bring their ID documents with them.

Some nearby verbs are:

• mang = bring/carry
• đem = bring/take
• cầm = hold/carry in the hand

Here, mang is a normal and natural choice in formal instructions.

Giấy tờ tùy thân means identification papers/documents or ID documents.

Breakdown:

• giấy tờ = papers, documents
• tùy thân = personal, carried on one’s person, for identification

Together, giấy tờ tùy thân refers to things like:

• national ID card
• passport
• driver’s license
• other personal identification documents

It is a fixed expression, so learners should try to remember it as one unit.

Để often means in order to, to, or for the purpose of.

In this sentence:

• mang giấy tờ tùy thân = bring ID documents
• để cấp lại thẻ = to reissue the card / for reissuing the card

So để connects the action and its purpose: bring ID documents in order to have the card reissued.

It is very common in Vietnamese for expressing purpose.

Cấp lại thẻ means reissue the card.

• cấp = issue, grant, provide officially
• lại = again
• thẻ = card

So cấp lại thẻ literally means issue the card again.

Important point: even though chủ thẻ is the subject of the sentence, the cardholder is probably not the one doing the official reissuing. In real-world meaning, the cardholder brings ID so that the relevant office or institution can reissue the card.

So in English, the most natural understanding is: The cardholder brings ID documents to have the card reissued.

Yes. Để được cấp lại thẻ would be more explicit.

• để cấp lại thẻ = to reissue the card
• để được cấp lại thẻ = to be reissued the card / to get the card reissued

The word được makes it clearer that the cardholder is the receiver of the action, not the one officially performing it.

So:

• Chủ thẻ mang giấy tờ tùy thân để cấp lại thẻ.
• Chủ thẻ mang giấy tờ tùy thân để được cấp lại thẻ.

Both can appear, but the second version is clearer if you want to avoid ambiguity.

Because the two instances do different jobs.

• chủ thẻ is a fixed noun phrase meaning cardholder
• the final thẻ is the actual object being reissued: the card

So even though English might avoid repeating card, Vietnamese naturally uses it twice here.

This kind of repetition is normal and does not sound strange in Vietnamese.

By itself, it could be understood as either singular or plural, depending on context.

• chủ thẻ can mean the cardholder
• in notices or regulations, it may also function like cardholders

Vietnamese nouns usually do not show singular/plural automatically. Context tells you which one is intended.

If someone wanted to make it clearly plural, they might say:

• Các chủ thẻ mang giấy tờ tùy thân để cấp lại thẻ.

But in official notices, the singular form is often used generically.

It is grammatically a complete sentence, but in real use it often functions as an instruction or requirement.

Administrative Vietnamese often uses short, compact statements like this instead of fuller wording such as:

• Chủ thẻ phải mang giấy tờ tùy thân để làm thủ tục cấp lại thẻ. = The cardholder must bring identification documents to carry out the card reissuance procedure.

So your original sentence sounds like the kind of thing you might see on:

• a notice
• a form
• a checklist
• an office instruction

Both can refer to getting a new card after loss, damage, expiry, or correction, but the tone is different.

• cấp lại thẻ = more official, administrative, institutional
• làm lại thẻ = more everyday, conversational

So:

• cấp lại thẻ is what you might see in official documents
• làm lại thẻ is what people often say in casual speech

Example:

• Tôi muốn làm lại thẻ. = I want to get my card remade/reissued.
• Hồ sơ cấp lại thẻ = documents for card reissuance

The structure is:

Chủ thẻ / mang giấy tờ tùy thân / để cấp lại thẻ

That is:

• subject: Chủ thẻ = the cardholder
• verb phrase: mang giấy tờ tùy thân = bring ID documents
• purpose phrase: để cấp lại thẻ = in order to reissue / have the card reissued

So the overall pattern is:

Subject + verb + object + purpose

This is a very common Vietnamese sentence pattern.
