Telecommunication carriers will receive invoices in September for their share of the annual costs of the NANP Fund. The invoices are due 30 days from the date of the invoice. Reassessment of fees may occur throughout the year based on updated data received from USAC each month. Invoices are sent out by email unless an email address is not provided on the Form 499-A, Line 208 or if the carrier has notified us that they want a paper copy only. The invoice contains information about the legal obligations under the Debt Collections Improvement Act (DCIA) and instructions on how to make a payment.

All telecommunication carriers in the United States shall complete a Telecommunications Reporting Worksheet (FCC Form 499-A) which sets out the information needed to calculate the fee.

The telecommunication carrier’s end-user telecommunications revenue obtained from the Form 499-A (420A+412A-511A)  is multiplied by a contribution factor to obtain the fee payable. The minimum fee is $25. If the carrier has no end-user telecommunications revenue they still must contribute $25. See 47 C.F.R. Section 52.17.

There is no de minimis exemption.

Failure to file the Form 4999-A reporting worksheet can result in a late filing fee. The late filing fee is charged to any carrier that fails to file their Form 499-A within 30 days of due date of the Form 499-A.

As stated in the Instructions to the Telecommunications Reporting Worksheet in Section F – Compliance, the fund administrators may each bill the filer for administrative costs that are caused by late or inaccurate filing of the Form 499-A.

The late filing fee is $100.00.

As per FCC Order 18-177 a database containing reassigned number information from all providers that obtain U.S. geographic numbers is to be created. The purpose of the Reassigned Numbers Database (RND) is to address the problem of unwanted calls to consumers with numbers reassigned from a previous consumer. The funding for the creation of the database is to be collected from telecommunication providers using the same mechanism used to recover costs for the NANPA. Providers will be refunded the fee for the creation costs over time from the user fees of the database.

NANP is required by the Debt Collection Improvement Act (DCIA) to impose interest and to inform service providers what may happen if the debt is not paid since the unpaid amount represents debt owed to the U.S. government.  NANP will charge an interest rate at an annual rate equal to U.S. Treasury rate as at the date of delinquency plus 3.5% from the date the invoice was due. Invoices that are not paid by the due date shown on the invoice will be subject to these charges.  If the amount of the calculated charge is less than $1, the late payment charge will be waived. These details are included on the backside (second page) of the invoice.

Any debt owing to the NANP fund is a debt owed to the United States as defined by 31 U.S.C. Section 3701, the Debt Collection Act of 1982 and the Debt Collection Improvement Act (DCIA) of 1996.  If the debt remains unpaid for 120 days or more, the debt must be transferred to the U.S. Department of Treasury (Treasury) for collection, however, debt may be transferred to Treasury at any time after 90 days past its due date.  Additional fees will be added by Treasury for administrative costs of processing and collecting the unpaid debt.

Statements of account are mailed out on a monthly basis to those service providers that have an outstanding debt.

In addition to the requirements of the DCIA, NANP is also required to follow the FCC rules regarding overdue balances known as the Red Light Rule (see DCIA  47 C.F.R section 1.1112, 1.1116, 1.1167 and 1.910 of the FCC’s rules). When a service provider’s account becomes delinquent by one day, that entity and any associated entity sharing the same taxpayer identification number (TIN) will be subject to the Red Light Rule.  If a service provider is owed a refund, payment will be withheld until the service provider satisfies any debt owed that is listed on the Red Light.

The service provider may check its Red Light status at any time by accessing the FCC’s Commission Registration System (CORES) at
