What is EPC?
Published May 8, 2026
EPC — the E-Rate Productivity Center — is USAC's authenticated portal at portal.usac.org where applicants file Form 470, Form 471, and Form 486; service providers manage SPIN profiles and respond to applicants; and both parties handle post-commitment changes. EPC data is non-public; only certified filings are republished on the USAC Open Data Portal.
Who uses EPC?
Applicants — schools, school districts, libraries, library systems, and consortia — log in to EPC to maintain their entity profile, file Form 470 / Form 471 / Form 486, attach contracts, respond to PIA Information Requests, and submit post-commitment changes.
Service providers log in to EPC to maintain their SPIN profile, view filings tied to their SPIN, certify Form 473 (SPAC), and submit Form 474 (SPI) invoices.
How does EPC relate to opendata.usac.org?
EPC is the operational system of record. opendata.usac.org is the publication layer USAC uses to release certified, non-sensitive subsets of EPC data to the public. Drafts, pending filings, internal review notes, and PIA correspondence stay inside EPC and are not republished.
Tools that index E-Rate data — including ERateSignal — work exclusively from the open-data publication, not from EPC.
Why is EPC data non-public?
EPC has its own Terms of Service that prohibit redistribution of authenticated content. The non-public posture also reflects the spirit of 47 CFR § 54.503: pre-certification draft filings could expose information that would compromise the open-and-fair competitive bidding process if circulated outside the applicant.
Common questions
- Where do I log in to EPC?
- EPC is at portal.usac.org. Sign-in uses the same credentials as a usac.org account, with multi-factor authentication required.
- Is EPC data public?
- No. Only certified filings — and the subsets USAC chooses to publish — appear on opendata.usac.org. Drafts, pending review notes, and PIA correspondence are not public.
- Can ERateSignal pull data from EPC?
- No. ERateSignal sources data exclusively from opendata.usac.org. EPC's Terms of Service prohibit scraping or redistribution of authenticated content.
