To use the CS411 service, mobile consumers simply send their search query to shortcode C-S-4-1-1 (27411) and enter their search query. The query can be the name or type of business along with a location entered as city or ZIP code. So, someone looking for pizza in New York might enter "Pizza.10001" or Pizza.New York, NY."

The request will return up to four results with names, phone numbers, addresses and Citysearch ratings of local businesses. Up to four relevant results will appear even if someone enters the name of a specific business or establishment. A search for "Spago" in Los Angeles, for example, would return information on that restaurant along with listings for other local Italian restaurants.

The CS411 service includes sponsored search results in which a marketer's name appears at the bottom of the screen showing business listings.
