LOCAL NUMBER PORTABILITY
This fee started to appear on many local telephone bills in February 1999. This fee allows local telephone companies to recover costs associated with supporting the technical capability to allow a consumer or business to retain their existing telephone number when switching to another local provider. Local companies are allowed, but not required, to pass on these costs. However most do. They are only allowed to charge this fee for five years from the first date they start to charge the fee, and are not allowed to start charging the fee until they can provide the ability to the end-user of retaining their phone number in the event of switching local telephone companies. Local telephone companies are required to make this "number portability" service available within 6 months of being requested to do so by another local telephone company wishing to service the area. This is NOT a tax. It is a charge that is part of the price you pay to your local telephone company. Neither the FCC nor any other government agency receives the Local Number Portability fee. Local telephone companies are not allowed to charge this fee for customers on the Lifeline Assistance Program.

PICC
Pronounced "pixie." This charge started on January 1, 1998 as part of the FCC overhaul of telephone fees. Long distance companies pay a flat fee to the local telephone company when you pre-subscribe your telephone line to their long distance service. (Sometimes referred to "Dial 1" or "Plus 1" service) The charge is designed to compensate the local telephone companies for the costs associated with providing "local loop" service. If a consumer or business has not selected a long distance company for its telephone lines, the local telephone company may bill for the PICC. Although every long distance company is charged the same flat rate per line, long distance companies are allowed to recharge you for this in any way they see fit, and each company uses a different method to charge this carrier specific fee. It is normally not presented to you in such a way that you would think it is a competitive pricing issue. But it is! Some companies do not charge this fee at all, and some charge a carrier specific flat fee. We offer full details of the amazing differences in this rate on the Fees Comparison page. This is NOT a tax. Please note that on July 1, 2000 the FCC ruled that long distance companies no longer will have to pay this fee to local companies for residential lines, or single line businesses. The charge continues for multiple line businesses. Many long distance companies are still charging you for this, even though they aren't paying it anymore!
