मोबाइल नंबर यहाँ लिखिए।

लिखिए is a polite imperative form of the verb लिखना (to write).

So:

• लिखना = to write
• लिखिए = write, please / please write

This form is commonly used in instructions, polite requests, signs, and forms. It sounds respectful and natural in public-facing language.

In Hindi, words like your are often omitted when they are obvious from context.

So मोबाइल नंबर यहाँ लिखिए naturally means:

• Write your mobile number here

Even though your is not explicitly stated, the meaning is understood.

If you want to make it explicit, you could say:

• अपना मोबाइल नंबर यहाँ लिखिए।
  = Write your mobile number here.

Here, अपना means one’s own / your own.

यहाँ means here.

In this sentence:

• मोबाइल नंबर = mobile number
• यहाँ = here
• लिखिए = write / please write

Hindi often places location words like यहाँ before the verb, so मोबाइल नंबर यहाँ लिखिए is very natural.

A very literal word-by-word sense would be:

• mobile number here write

But in natural English, it becomes:

• Write your mobile number here.

It is largely borrowed from English, and that is completely normal in modern Hindi.

• मोबाइल comes from mobile
• नंबर comes from number

Hindi uses many English loanwords, especially for technology, phones, forms, and everyday urban speech.

You may also see similar expressions such as:

• फ़ोन नंबर = phone number
• मोबाइल नम्बर = same meaning, different spelling of number

All of these are common.

This is about politeness and formality.

Different imperative forms in Hindi show different levels of respect:

• लिख = very direct, often too blunt by itself
• लिखो = informal, used with friends, younger people, or someone you speak to casually
• लिखिए = polite/respectful
• लिखिएगा = even softer / more courteous in some contexts

On a form, notice, or polite instruction, लिखिए is the expected choice.

So:

• मोबाइल नंबर यहाँ लिखो।
  sounds informal
• मोबाइल नंबर यहाँ लिखिए।
  sounds polite and appropriate

Yes. Hindi word order is fairly flexible, especially with adverbs like यहाँ.

These are all possible:

• मोबाइल नंबर यहाँ लिखिए।
• यहाँ मोबाइल नंबर लिखिए।
• यहाँ अपना मोबाइल नंबर लिखिए।

They all mean essentially the same thing, though the emphasis shifts slightly.

• यहाँ मोबाइल नंबर लिखिए puts early focus on here
• मोबाइल नंबर यहाँ लिखिए starts with what you should write

The original sentence sounds very natural in an instruction context.

लिखिए is usually pronounced roughly as:

• likhiye

A simple breakdown:

• लि = li
• खि = khi
• ए at the end combines so the whole thing becomes likhiye

So the full sentence is approximately:

• mobāil number yahā̃ likhiye

A few pronunciation notes:

• यहाँ has a nasal sound at the end: yahā̃
• ख in लिखिए is an aspirated k sound, like kh

Both spellings are used, and both represent the same word in everyday writing.

• लिखिए
• लिखिये

In modern standard spelling, लिखिए is generally preferred, but लिखिये is also very common and widely understood.

So if you see either one, the meaning is the same: please write.

That mark is called the danda.

It functions like a full stop / period in Hindi and other Devanagari-based writing traditions.

So:

• मोबाइल नंबर यहाँ लिखिए।

is the same as ending an English sentence with .

In modern informal Hindi typing, especially on phones or online, people often use a regular period instead, but । is the traditional and standard mark.

It is especially natural as a written instruction, such as on:

• a form
• a sign
• a registration sheet
• an exam paper
• a reception desk document

In speech, a native speaker might also say it, but often with something added, such as:

• यहाँ मोबाइल नंबर लिखिए।
• अपना मोबाइल नंबर यहाँ लिखिए।
• यहाँ अपना नंबर लिख दीजिए।

That last version, लिख दीजिए, sounds a bit more conversational and polite.

Yes, depending on the situation.

Some alternatives are:

• भरिए = fill in
  
  • मोबाइल नंबर यहाँ भरिए।
• दर्ज कीजिए = enter / register
  
  • more formal
• डालिए = put / enter
  
  • common in some contexts, especially digital ones

But लिखिए is simple, clear, and very common when someone is expected to physically write something down.

So for a learner, मोबाइल नंबर यहाँ लिखिए। is an excellent basic pattern to know.
