Bank of America Corp. (BAC) on Monday said it will eliminate 1,900 jobs by closing three call centers by year end, as part of its integration of credit card issuer MBNA Corp.

The No. 2 U.S. bank will close a call center in Dover, Delaware, eliminating 630 jobs, spokeswoman Betsy Weinberger said. It will also close a center in Horsham, Pennsylvania, which employs 600 people, and one in Colorado Springs, Colorado, which employs 670, Weinberger said.

Bank of America has said it plans to cut about 6,000 jobs across both companies following its $34.2 billion purchase on January 1 of MBNA.

The purchase made Bank of America the largest U.S. credit card issuer. MBNA had been based in Wilmington, Delaware.
