Survey Score

RealCheck Postal

Collects and evaluates names and postal addresses against third-party consumer databases to determine if they're legitimate and correspond with one another. Provides confidence in knowing that a participant is who they say they are and lives where they say they live.

RealCheck Social

For records that fail RealCheck Postal or where a postal address is unknown, we evaluate respondents’ names and email addresses against third-party databases of social and other online sources.


TrueSample is the industry’s only solution to proactively identify duplicates both within an individual sample source as well as across all of the sample sources represented in the TrueSample ecosystem.

Geo-Location Distance Check


Validated and de-duped PII is a good starting point, but TrueSample's Sample Validation software allows you to take your validation(s) to an even deeper level with it's geo-location distance check.  It will tell you the distance (in miles) between the latitude/longitude coordinates of the postal address and the latitude/longitude coordinates that the users IP address resolves to.  There is no magical number where the distance becomes too far, so we allow you to have the flexibility to decide what your risk threshold is and decide what "too far" is for your business.
