I have recently added a second phone number to the Google My Business Profile listing but always it shows only one in the Profile Panel. Please could you tell me why Google Business Profile doesn’t show two phone numbers?
Even though you can add up to 3 phone numbers (primary number and the other two as additional phone numbers):
However, Google will only display the primary phone number in your Google My Business Profile Public Panel on Google Search and Google Maps listings. But the other 2 phone numbers are important if you have citations with different phone numbers.
In this article, I show how to add/change a phone number.
If you wish to know more about phone numbers, other settings and how to take advantage of them, please check my Google Business Profile Training – GBPedia.
Hope it helps
