Online Item 21 Attachment
You may use this automated system to create and electronically submit your Item 21 Attachment for FCC Form 471. To use this interface you must have already submitted an electronically-filed Form 471 and know the Security Code provided during that process.
For each Item 21 Attachment you file online, the service provider whose SPIN is featured on the associated FRN will be able to view and download the information specific to that FRN once you click the "Submit Item 21" button.

USAC encourages the use of this online filing system. However Item 21 Attachments also may be manually submitted by mail, by fax, or by e-mail. For information on filing Item 21 attachments, including manual filing options, refer to the Item 21 Attachments document in the Reference Area of the USAC website.
