room number

This time she gave her name and room number all over again, up front.

"Would you be so kind as to give me your name and room number?"

"Do you think it was a good idea to give him your room number?"

They appeared to know the boy quite well, and asked for his room number.

I remember because she didn't know the room number and asked for him by name.

We'd like to know whatever other name he might be using and his room number.

They gave her the room number and mother went ahead so fast.

Why would he have needed to know her room number?

His room number told him he was on the third floor.

I've had your room number for an hour, and done nothing but call.
