Google knows the marketing and branding power of a good domain name. Google's parent Alphabet owns over 18,000 domains.
Owning a misspelling of your business name, or your .COM name in other extensions, like .US, .DE, .GLOBAL, and .IO can enhance your visibility.
I do not know the phone number or postal address of one hundred businesses but I'll bet I know the domain names of at least that many: uber.com, lyft.com, google.com, facebook.com, yelp.com, trevago.com, priceline.com, apple.com, samsung.com wallmart.com, ebay.com, netflix.com, salesforce.com, tripadvisor.com, groupon.com, spotify.com, twitter.com, . . .
