The Iowa Dual Party Relay Service (DPRS) law found in Iowa Code chapter 477C requires wireless carriers and wire-line local exchange carriers that provide telecommunications service in Iowa to pay three cents ($0.03) per month for each telecommunications service phone number provided in Iowa.

Telecommunications companies report their revenue-producing telecommunications service phone numbers for the previous calendar year in IUB 24/7. All companies maintain a company profile in IUB, which offers a single place to submit required information and DPRS reports. Invoices are then issued for the assessment amount owed. 

Filing Deadline

The reports are made available in January and the annual filing deadline is April 1 for each telecommunications company required to submit the reportable DPRS information.

Instructions for using IUB 24/7 can be found on the Information About IUB 24/7 webpage. Instructions on creating a company profile in IUB 24/7 can be found on the IUB 24/7 for Telecommunications Companies webpage.
