Zone Unit Charges on bill

[djwrb]

I was checking my bill and I noticed that there are 2 phone numbers that show up under zone unit charges.  They are only showing up once a month.  No one in our house have any idea what those numbers are.  If we call out of the area,  we will only use our cell phone because I know that our landline is for local calls only.

    Is there any way to find out what those numbers are?  

Thank you in adance.

You are talking to peers here.

Did you  make any attempt to look up those numbers?
