Usually this is because they're using data from TargusInfo that is 
woefully outdated, based on Directory data, or a number of other issues.

Syniverse and TNS use this data for their SS7 based CNAM products (as 
well as their IP based ones, if I recall).

Thus those who use those providers will often see such discrepancies.

Very frustrating.
