Does GMB Secondary Phone Number Show Up Anywhere?

[Marissa]

If you put a primary and secondary phone number in your Google My Business, will the secondary phone number actually show up anywhere? Does Google switch out the 2 numbers and shows the secondary one half of the time, or will the knowledge panel show 2 phone numbers?

Nope, it doesn't show anywhere.

The only place it would show is if you create a GMB website.
