Please see the possible cases below, and follow the solution case by case.
1: Your Google My Business Listing Is not verified.
Make sure your business information is accurate and that only you, the business owner or manager, has access to it by verifying your business. Most local businesses verify by mail. Some businesses, like service area businesses, have other verification options, like verification by email, phone, or Search Console. See the guide here.
2. You recently added or edited your business information.
Our search results are based on algorithms that take a wide range of factors into account. When you make changes to your business information, it may shift that balance a bit. Your changes may take up to 3 days to appear.
You should still be able to find your business after making edits by searching for it by name on Google Maps.
3. Your business information doesn’t comply with Google's recommendation.
Following these guidelines helps avoid common problems, including changes to your information, or, in some cases, removal of your business information from Google.
