Google combines residential and business phone number information and its own excellent interface to offer a phonebook lookup that provides listings for businesses and residences in the United States. However, the search offers three different syntaxes, different levels of information provide different results, the syntaxes are finicky, and Google doesn't provide documentation.
The Three Syntaxes
Google offers three ways to search its phonebook:
phonebook
Searches the entire Google phonebook
rphonebook
Searches residential listings only
bphonebook
Searches business listings only
Using a standard phonebook requires knowing quite a bit of information about what you're looking for: first name, last name, city, and state. Google's phonebook requires no more than last name and state to get started. Casting a wide net for all the Smiths in California is as simple as:
phonebook:smith ca
phonebook:john smith los angeles ca
At the time of this writing, the Google phonebook found 2 business and 20 residential listings for John Smith in Los Angeles, California.
Caveats
The phonebook syntaxes are powerful and useful, but they can be difficult to use if you don't remember a few things about how they work.
Syntaxes are case-sensitive
Searching for phonebook:john doe ca works, while Phonebook:john doe ca (notice the capital P) doesn't.
Wildcards don't work
Then again, they're not needed, since the Google phonebook does all the wildcarding for you. For example, if you want to find shops in New York with "Coffee" in the title, don't bother trying to envision every permutation of "Coffee Shop," "Coffee House," and so on. Just search for bphonebook:coffee new york ny and you'll get a list of all businesses in New York whose names contain the word "coffee."
Exclusions don't work
Perhaps you want to find coffee shops that aren't Starbucks. You might think phonebook:coffee -starbucks new york ny would do the trick. After all, you're searching for coffee and not Starbucks, right? Unfortunately not; Google thinks you're looking for both the words "coffee" and "starbucks," yielding just the opposite of what you were hoping for: everything Starbucks in NYC.
OR doesn't always work
You might be wondering if Google's phonebook accepts OR lookups. You then might experiment, trying to find all the coffee shops in Rhode Island or Hawaii: bphonebook:coffee (ri hi). Unfortunately, that doesn't work; the only listings you'll get are for coffee shops in Hawaii. This is because Google doesn't see the (ri hi) as a state code, but rather as another element of the search.
So, if you reverse the previous search and search for coffee (hi ri), Google would find listings that contain the word "coffee" and either the strings "hi" or "ri." This means you'll find Hi-Tide Coffee (in Massachusetts) and several coffee shops in Rhode Island.
It's neater to use OR in the middle of your query and specify a state at the end. For example, if you want to find coffee shops that sell either donuts or bagels, this query works fine: bphonebook:coffee (donuts bagels) ma. It finds stores in Massachusetts that contain the word "coffee" and either the word "donuts" or the word "bagels." The bottom line: you can use an OR query on the store or resident name, but not on the location.
Reverse Phonebook Lookup
All three phonebook syntaxes support reverse lookup, though it's probably best to use the general phonebook: syntax to avoid not finding what you're looking for due to a residential or business classification.
To do a reverse search, just enter the phone number with area code. Lookups without area code won't work:
phonebook:(707) 827-7000
