Residents in Marshall County may be eligible for credits on their cell phone bill if it was not purchased within the county.

Deborah Pennypacker, Marshall County E-911 Coordinator, said many residents of the county have paid 911 cell phone fees for other counties. Residents that paid 911 cell phone bills before January 2011 are due credit on their bill.

"I was trying to figure out how companies find out a primary place of use and it is supposed to match your billing address," Pennypacker said. "And that does not always match your primary place of use."

Pennypacker cited herself as an example. Prior to moving to Marshall County she worked in Oklahoma City and after moving, she was paying fees to Logan County. She received a $64 credit on her phone bill and cited another example where a Marshall County resident received a $100 credit.

"This would apply for any county," Pennypacker said. "People move from other places and the cell phone company isn't careful. With us being a tourist county and we have people coming here to retire, it could have a big impact and give us more funding."

The location where people activate their cell phone can become the primary place of use in the phone company records. The PPU should indicate a physical address and is also an indication if a customer lives in a 911-fee area. If the PPU is incorrect, the company owes a credit.

To determine if the PPU is correct, contact the phone company.
