NAP consistency.In plain English.

Google's guidelines say your business name should be your real-world name, as used consistently on your storefront, website and stationery and as known to customers, and that adding unnecessary information to it can get the profile suspended.

Put a suite number in Address Line 2, and use a phone number under the business's direct control, preferably a local one.

Google builds profiles partly from crawled web content and licensed data from third parties, so a wrong number elsewhere can find its way into your profile. It also says inaccurate information can keep a profile out of relevant searches.

Neither Google nor Bing calls consistency across sites a ranking factor by name. Pick one exact version, including suite numbers and abbreviations, and use it everywhere, so customers and AI answers get the right details.

Example: '123 Main St, Suite 4' on Google, '123 Main Street #4' on Yelp and an old phone number on a directory are three versions of one business. One exact version on all three removes the doubt.
