The ARRL Net Directory Search shows Amateur Radio nets that have been registered with ARRL HQ net directory database. It primarily covers nets that are of interest to Amateur Radio operators in the United States and Canada. Worldwide coverage nets and maritime service nets are featured (as are National Traffic System Area and Region Nets) in the database.

One focus of the directory is toward public-service oriented nets that support the ARRL National Traffic System (NTS) and the Amateur Radio Emergency Service (ARES).
