If you are a National Fuel customer, beware of a scam that's taking place at the doorstep of many homes.
Scammers are posing as workers from National Fuel. 

The company says any National Fuel employee carries valid identification, which is visibly noticeable to a customer.
They do not ask to see bills, or for bill payment. The company, also, does not ask to replace gas meters at the customers expense.

If you feel that a suspicious person has come to your door as part of this scam, contact National Fuel at 1-800-365-3234 or your  local police department.
