CLINTON, Iowa — A Clinton County group is warning about an alleged phone scam.

Some Clinton County residents reported receiving recorded phone calls Tuesday purporting to be from IH Mississippi Valley Credit Union, asking the resident to call another number to “re-authorize” their debit card by leaving their card number and other information, according to a news release from Randy Meier, director of Seniors vs. Crime.

Meier said the calls did not come from the credit union.

Consumer should never share personal information, such as bank account numbers, to telephone callers, Meier said.

Such “robo-calls” are not uncommon or unique to the credit union, said Laura Ernzen, the company’s vice president of marketing. Ernzen said the credit union works to shut down phone numbers or websites that appear to be scams, and keeps customers updated on possible scams through its website.
