How do I search for telephone numbers if I know the type of service but not the NY State agency that provides the service?

 The NYS Office of General Services provides a telephone directory by function as a public service. The telephone numbers listed are a compilation from the questions called in to the OGS telephone operators. The numbers are associated with a function or service, generally provided by a New York State Agency. This listing is not comprehensive and does not include every State Agency function.
