The file, which provides in-depth, goneaway suppression coverage for marketers, was previously only available directly via Experian's integrated marketing division.
Richard Lees, Chairman at Database Group, said: "Over the past few years, we have seen a substantial increase in client demand for Experian's Absolute Movers suppression file.
"This has increased even more in today's economic climate where it is vital that companies optimise the return on investment on direct marketing campaigns."
Database Group is the first reseller to sign up to access the file.
