The loss of a Wellmark Inc. contract at Equifax Inc.'s call center in Carlisle has forced the company to shutter that operation, said Warren County Economic Development Director Jason White.

However, 49 of the 52 workers at the Carlisle operation will be offered jobs at the Equifax location on Ashworth Road in West Des Moines. Equifax acquired Greater Des Moines-based DataVision Resources Inc. in 2011. DataVision provided verification and other services to the insurance, mortgage and financial services industries.

Equifax is based in Atlanta and provides credit and other financial information services to businesses and consumers.
