Both are noun + noun combinations, which are very common in Korean.

• 회수 날짜 = collection/retrieval date or pickup date, depending on context

  • 회수 = recovery, collection, retrieval
  • 날짜 = date

• 접수 번호 = receipt/application number or registration number, depending on context

  • 접수 = receipt, acceptance, filing, application intake
  • 번호 = number

In Korean, the first noun modifies the second noun, similar to how English says pickup date or application number.

와 means and.

Korean has two forms for and when linking nouns:

• 과 after a consonant
• 와 after a vowel

Since 날짜 ends in the vowel sound ㅏ, it takes 와:

• 날짜와
• not 날짜과

So 회수 날짜와 접수 번호 means the collection date and the receipt number.

Because the two nouns are treated as one combined object of the verb.

So this structure works like:

• 회수 날짜와 접수 번호를 확인했습니다
• checked [the collection date and the receipt number]

The object marker 를 applies to the whole coordinated phrase, so it only needs to appear once, at the end.

This is similar to English, where you would not say checked the date and the number the. The marker naturally comes after the full noun phrase.

확인했습니다 comes from the noun 확인 meaning confirmation/check plus the verb 하다 meaning to do.

So:

• 확인하다 = to check, to confirm
• 확인했습니다 = checked / confirmed

Breakdown:

• 확인 = confirmation, checking
• 하 = do
• 였/했 = past tense
• 습니다 = formal polite ending

Because 하다 combines with many nouns, this is a very productive pattern in Korean.

Examples:

• 예약하다 = to make a reservation
• 신청하다 = to apply
• 확인하다 = to check/confirm

Korean is basically an SOV language: subject–object–verb.

So while English often says:

• I checked the date and the number

Korean puts the verb last:

• (I) the date and the number checked

That is why 확인했습니다 comes at the end.

This is one of the most important word-order differences between English and Korean.

It is past tense and formal polite.

• -았습니다 / -었습니다 / -했습니다 = formal polite past
• 확인했습니다 = checked / have checked

This style is common in:

• customer service
• office communication
• announcements
• reports
• business writing

It sounds respectful and professional.

It can correspond to either in English, depending on context.

Korean past tense often covers meanings that English might express as:

• I checked
• I have checked
• We confirmed

So 회수 날짜와 접수 번호를 확인했습니다 could be used when reporting a completed action, especially in a business or service setting.

The exact English translation depends on the situation, but the Korean form itself is simply past tense.

The subject is omitted, which is very normal in Korean.

Korean often leaves out subjects when they are obvious from context. So this sentence could imply:

• I checked...
• We checked...
• It has been checked...

depending on who is speaking and the situation.

In natural Korean, including the subject every time would often sound unnecessary.

Yes. 회수 can mean things like:

• collection
• retrieval
• recovery
• recall
• pickup

So 회수 날짜 might be understood differently depending on the situation:

• package pickup date
• item collection date
• recovery date
• recall date

A learner may want to avoid assigning one fixed English meaning to 회수 in every context. The core idea is something being taken back, collected, or retrieved.

Yes, though they can overlap.

• 날짜 = date, calendar date
• 날 = day
• 일자 = date; often more formal or document-like

In this sentence, 날짜 is the most natural everyday word for date.

So 회수 날짜 means the actual calendar date related to the collection/retrieval, not just a vague day.

Yes. A few common versions are:

• 회수 날짜와 접수 번호를 확인했어요.
  Polite but less formal

• 회수 날짜와 접수 번호 확인했어요.
  Very common in speech; the object marker is omitted

• 회수 날짜와 접수 번호 확인했어.
  Casual, informal

The original 확인했습니다 is more formal and businesslike.

Yes, grammatically you could say:

• 접수 번호와 회수 날짜를 확인했습니다.

That would still be correct.

The difference is mainly about emphasis or what sounds more natural in context. Korean often allows this kind of reordering with coordinated nouns, as long as the overall meaning stays clear.

Because Korean spacing usually separates larger units, not every modifying relationship.

Here:

• 회수 날짜 is a two-word noun phrase
• 접수 번호 is another two-word noun phrase
• 확인했습니다 is the verb phrase

Even though 회수 날짜 functions like a single idea in English (pickup date), Korean commonly writes noun modifiers as separate words.

So the spacing is normal:

• 회수 날짜와 접수 번호를 확인했습니다

not:

• 회수날짜와 접수번호를 확인했습니다

In some specialized or less careful writing, you may see compounds written together, but the spaced version is standard and safer for learners.
