Belge numarası dilekçe ekinde bulunuyor.

This is a very common Turkish noun compound pattern.

• belge = document
• numara = number
• numarası = its number

So belge numarası means document number.

In Turkish, when one noun modifies another noun, the second noun often takes the 3rd person possessive suffix:

• kimlik kartı = identity card
• telefon numarası = phone number
• belge numarası = document number

Even though English does not say document’s number here, Turkish uses that structure.

Yes, literally it is very close to the document’s number or the number of the document.

But in natural English, we usually translate it as document number.

So:

• literal structure: document + its number
• natural meaning: document number

This is normal in Turkish and very common.

It means in the attachment/appendix/enclosure of the petition/application.

Breakdown:

• dilekçe = petition, application, formal written request
• ek = attachment, appendix, enclosure
• eki = its attachment
• ekinde = in its attachment

So dilekçe ekinde means:

• in the attachment to the petition
• in the appendix of the application
• among the enclosed documents of the petition

The exact English wording depends on context, especially in legal or bureaucratic language.

Because there are two grammatical pieces added to ek:

1. -i → possessive suffix
   ek → eki = its attachment

2. -de → locative suffix, meaning in / on / at

When a case suffix like -de comes after a possessive ending, Turkish usually inserts a buffer n:

• eki + nde = ekinde

So:

• ek = attachment
• eki = its attachment
• ekinde = in its attachment

This n is very common after possessive forms:

• evinde = in his/her house
• arabasında = in his/her car
• ekinde = in its attachment

Not in this sentence. Here bulunuyor means something like:

• is located
• is found
• appears
• is present

The verb is bulunmak. In formal Turkish, especially in documents, it often means that something exists in a place or is located there.

So Belge numarası dilekçe ekinde bulunuyor means the document number is in the attachment, not that someone is actively finding it.

This use is more formal than everyday var in many contexts.

Both can relate to existence or location, but they are not exactly the same in tone.

• var = there is / exists
• bulunuyor = is located / is present / is contained

In official, written, or formal language, bulunuyor often sounds more natural.

Compare:

• Belge numarası dilekçe ekinde var.
  = The document number is in the attachment.
  This is understandable, but less formal.

• Belge numarası dilekçe ekinde bulunuyor.
  = The document number is located in the attachment.
  This sounds more official and document-like.

Because in Turkish, -yor is used not only for actions happening at this moment, but also for current states and general present situations.

So bulunuyor here does not mean something dramatic like is currently being found right now. It simply means:

• is located
• is present
• can be found

This is very normal with stative or semi-stative meanings in Turkish.

Turkish does not have a direct equivalent of English the.

Definiteness is usually understood from:

• context
• word order
• case endings
• the situation

So belge numarası can mean:

• the document number
• a document number

But in this sentence, the context strongly suggests the document number.

That is very normal in Turkish.

Yes. It is very normal.

The sentence is:

• Belge numarası = subject/topic
• dilekçe ekinde = location
• bulunuyor = verb

A very common Turkish pattern is:

subject/topic + place + verb

So this sentence is perfectly natural.

You could also say:

• Dilekçe ekinde belge numarası bulunuyor.

That shifts the emphasis slightly toward the location, but the meaning stays very similar.

Dilekçe is a specific kind of formal written request. Depending on context, it may be translated as:

• petition
• application
• formal request letter
• written request

In administrative or legal Turkish, dilekçe is very common. So here the sentence probably belongs to a formal or bureaucratic context.

Yes. Ek is a flexible word, and the best translation depends on context.

Possible translations include:

• attachment
• appendix
• annex
• enclosure
• supplement

So dilekçe ekinde could be translated in different ways depending on the document:

• in the attachment to the application
• in the appendix of the petition
• among the enclosures of the request

In official language, all of these may be appropriate depending on the exact situation.
