With random digit dialing (RDD) available in 21 countries and wireless/mobile RDD available in several countries, plus targeted and business samples, SSI provides sample you can trust the world over.

SSI's RDD methodology is unsurpassed in efficiency. Our RDD samples provide fewer dialings, faster completion, and improved interviewer morale. Our Screening Service makes random digit sampling more cost-effective. Selections can be targeted by age, income, and race/ethnic background.

Low-incidence sub-groups are easily targeted, enabling researchers to save money by honing in on the appropriate groups.

SSI's B2B samples offer comprehensive coverage of the business universe, proper nth selection procedures, and selection options to fit even the most rigorously defined research plan.

SSI-SNAP, the most sophisticated online sampling software available in the industry, is both a global sample ordering system and a tool for reformatting sample files. Offering 24/7 access to samples, SSI-SNAP has proved to be indispensable to survey researchers.
