We normally give telephones by saying each individual number in it:
Our phone number is two six three, three eight four seven. (263-3847)
When there is a zero (0) in our telephone number, we often say O like the name of the letter O.
e.g. 505-1023 = five-O-five, one-O-two-three.
If a phone number contains two of the same numbers together, we usually say double (number).
If a phone number contains three of the same numbers together, we usually say triple (number)
e.g. (212-8555) two one two, eight triple five.
The above rules for telephone numbers also apply to fax numbers.
To ask for someone's telephone number we say:
What's your phone number? It's 555-2565.
What is Woodward's phone number? It's 2789-0135.
We don't normally say: What's your telephone number? (Though it IS grammatically correct)
When you reply, you can give just your telephone number OR say: It's + (your phone number).
