What this change actually does
Linking your mobile number to your Alexa profile enables you to make and receive calls on Alexa-enabled devices using that number. It does not change your Amazon account's contact information or your device registration, it specifically connects your phone number to Alexa's calling and messaging features so that outgoing calls appear to come from your mobile number and incoming calls to that number can ring through your Echo devices. To confirm the update on your device, say "Alexa, what's my phone number?"
What if I can't find the setting?
If you cannot locate the option to change your number, check only in the Communication settings under More > Settings. Amazon's official help does not list a separate "verify" screen or a device-side menu path on Echo devices. The current number may be shown under Alexa App > More > Settings > Your Profile & Family > Mobile Number, but this is not an official help page. Before changing it, verify the current number in the Alexa app settings.
