The Federal Universal Service Charge (FUSC) contribution factor may increase or decrease quarterly. This will result in an increase or decrease in the charge that appears on your monthly telephone bill. This factor is applied to services designated as interstate by the FCC and changes from time-to-time based on the needs of the federal universal service fund. This government mandated program is designed to help keep local telephone service rates affordable for all customers, in all areas of the United States. The fund also provides schools, libraries, low-income consumers, and rural health care providers with assistance in obtaining telecommunications services. Please contact us with any questions.
