First Data Hygiene “Coder” – 19??

I think one of the first “data hygiene” coders that was commercially made available was Code1 by Group 1 Software around 1981.  My first job in 1983 was at Metromail Corporation located in Lincoln, NE and at that time we were using Code1.

Does 1981 sound about right?

Hmmm… ZIP Codes were first used by the USPS (Post Office) in 1965.  I guess between this time and the early 80’s there were a lot of “home grown” match engines out there using postal databases.

If anyone has any better “intel” please share!
