631 iPhone_iPad_Mac_apple

I cannot find an apple id anywhere in messages ...

I want to use my iPhone number instead of iCloud email address in my messages app on my Mac.How can I change it?

I think it is the reason some contacts messages are not delivered.

I have searched extensively for a way to solve this issue and found none yet, Please help.

one contact is using iphone. Messages are not delivered him. Another contact is using android messages delivered ok.

OS Sierra

Ver.10.12.6

Processor 2.4Gz intel core 2 duo
