What is ESL?
Published May 14, 2026
The Eligible Services List (ESL) is the annual document approved by the FCC and published by USAC that defines exactly which products and services qualify for E-Rate Category 1 and Category 2 funding in a given funding year. It is the authoritative reference for cost allocation, ineligible-feature carve-outs, and service-substitution decisions.
What does the ESL cover?
The ESL lists every category of eligible service: Category 1 connectivity options (fiber, cable, DSL, cellular data, dark fiber), and Category 2 internal-network items (switches, wireless access points, structured cabling, firewalls, BMIC, MIBS). It also enumerates ineligible features and ancillary items that must be cost-allocated out of E-Rate-funded equipment.
Each year's ESL is approved by the FCC before USAC publishes the version that applies to the upcoming funding year. The ESL changes year over year as the FCC adds, removes, or clarifies eligibility for specific products and services.
Why does the ESL matter for filings?
Form 471 line items must align with the ESL for the funding year in question. PIA reviewers check ESL eligibility on every FRN; an item not on the current ESL is denied. Service-substitution requests after commitment are also evaluated against the ESL of the original commitment year.
USAC publishes each year's ESL on usac.org — that document is the binding reference, not third-party summaries.
Common questions
- Where do I find the current Eligible Services List?
- USAC publishes the current ESL on usac.org. Each funding year has its own ESL version, and applicants must reference the version for the funding year they are filing against.
- Does the ESL change every year?
- It can. The FCC reviews and approves the ESL annually before USAC publishes it. Some years bring substantive changes (new categories, removed items); others are minor clarifications.
- What happens if a requested item isn't on the ESL?
- PIA denies the request. The applicant either drops the item, cost-allocates it out, or appeals — but ineligible items cannot be funded.
