Data Profiling Software for Data Discovery,Data Assessment,Data Analysis

Intelligent Search Technology (IST) can now flag records in your file that are deceased and addresses that correspond to prisons and correctional institutions.

How it works

Once your file is uploaded, IST will first process your data through the standard CASS Certified TM address verification process. We will then use deceased records to flag names in your file that have a DOD (Date of Death) within the last 3 years and a second flag for any addresses that match to an extensive database of over 10,000 correctional facilities.


  • Avoid sensitive situations, such as mailing to deceased individuals, that can cause adverse effects in your mailing and brand image
  • Eliminate state/federal prisons and other correctional institutions and save money on your next mailing
