Historical Data

Some data applications do not require the level of “freshness” that LSSiDATA's National Directory Assistance database and its related products (such as SmartMatch 2.0 and FirstConnex Plus 2.0) provide. Organizations searching for contact data in non time-critical applications, such as for online directories, data compilation, and data verification are thus frequent users of Historical Data.

Historical Data is developed from a series of "snap-shots" of the National Directory Assistance database which have been held in quarantine and aged. Historical Data contains the same data elements and extensive QUIC (Quality Update Identify & Change) process that goes into the National Directory Assistance database. Differences are the effective dates and the update cycle.

Historical Data is only available as a data feed.
