<p>It depends on how you look at the "numbers". Someone think they are words, especially when there are "-" sign or space between the numbers, so they ask "what". On the other hand, someone think they are pure numbers, so they ask "how many / much". 
But both of them are understandable for native speakers. </p>

<p>A telephone number is not an amount or quantity,  It is a <strong>specific code</strong> made up of numbers, not unlike an serial number made up of numbers . If you don't say "你手机的 serial number 是多少", then you shouldn't say "你的电话是多少" </p>

<p>No, it means "你的电话是多少" (your telephone is how many), which doesn't make sense;  If you say "你的电话是什么" people would understand you meant "你的电话号码是什么" (omitted 号码). But, grammatically 电话 /dianhua/ only means "telephone" , you need to add 号码 and say "电话号码" if you meant to ask "what is someone's phone number" instead of "what brand someone's telephone is" </p>

If someone ask me - "你的电话是多少", I might think he or she wants to buy my phone. :)

<p>Is it ok to ask:</p>
<blockquote>
<p>你的电话号码是什么? (What is your telephone number)</p>
</blockquote>
<p>Or do I have to say:</p>
<blockquote>
<p>你的电话号码是多少? which is the translation on Duolingo.</p>
</blockquote>
<p>Also, can I just say:</p>
<blockquote>
<p>&quot;你的电话是多少?</p>
</blockquote>
<p>because 电话 already means phone number.</p>

Im sorry Im posting an answer instead of using the comments section but Im not a member yet, so Im unable to do so. Thank you for your answer, but the usage described, in my question, of dianhua as "telephone/telephone number" and duoshao as "which (number)" is based on the duolingo course created by chinese speakers and this dictionary: https://www.mdbg.net/chinese/dictionary?page=worddict&wdrst=0&wdqb=Duoshao https://www.mdbg.net/chinese/dictionary?page=worddict&wdrst=0&wdqb=Dianhua

A phone number can be either considered a number of a string so both are okay.

# Is it okay to ask 你的电话号码是什么?

(Asked by: username_0 on 2018-06-09)

Is it ok to ask:

> 你的电话号码是什么? (What is your telephone number)

Or do I have to say:

> 你的电话号码是多少? which is the translation on Duolingo.

Also, can I just say:

> "你的电话是多少?

because 电话 already means phone number.

I'd say all of your sentences are used in practice within the mainland.

These are all correct expressions:

1. 你的电话号码是什么？
2. 你的电话号码是多少？
3. 你的电话是多少？

Colloquially, we even brief it like 你电话多少？ or 电话多少？

Hope this could help you.
