E-Rate for Public Libraries: Discounts, CIPA and the Forms That Matter
E-Rate can cover a large share of a library's internet and network costs. The rules were written with schools in mind, though, so libraries meet a few twists: how the discount is set, how the network budget is sized, and how CIPA is certified when a consortium applies on your behalf.
Is your library eligible for E-Rate?
Eligibility comes from federal library law, filtered through your state. Three questions settle it for most public libraries.
Does it meet the LSTA definition of a library?
E-Rate uses the definition of a library or library consortium in the Library Services and Technology Act. Public libraries generally qualify.
Ask: your state library agencyIs it eligible for state library agency assistance?
The library must be eligible for help from its state library administrative agency. Some states add their own minimum standards.
Ask: your state E-Rate coordinatorIs the budget separate from any school?
A library that shares a building or staff with a school must still have its own budget and pay for its own technology to apply as a library.
Check: dual-use and joint-use librariesAcademic, research and private libraries can be eligible in some cases depending on state rules and funding sources. The rest of this page assumes a public library or library system. For the school-side view of the same program, see our guide to E-Rate and CIPA funding.
A library filter that fits the E-Rate year
A library applying for E-Rate usually needs CIPA settings across several buildings. The hosted filter keeps each branch separate and gives the records for the file.
- Run for you as a DNS service, so branch staff have no appliance to look after.
- CIPA preset with Adult and VPN/Proxy on, plus optional categories.
- Staff PIN lets adults reach research material for 15, 30 or 60 minutes, logged.
How the library discount is calculated
Libraries do not have students, so they borrow a number. The discount is based on the share of students eligible for the National School Lunch Program in the public school district where the library is, and on whether the library is urban or rural.
| Students eligible in the school district | Category 1 urban | Category 1 rural | Category 2 urban | Category 2 rural |
|---|---|---|---|---|
| Under 1% | 20% | 25% | 20% | 25% |
| 1% to 19% | 40% | 50% | 40% | 50% |
| 20% to 34% | 50% | 60% | 50% | 60% |
| 35% to 49% | 60% | 70% | 60% | 70% |
| 50% to 74% | 80% | 80% | 80% | 80% |
| 75% to 100% | 90% | 90% | 85% | 85% |
Which district?
The public school district where the library is located. For a library system, the district of the main branch is used. Make sure the right district is in your applicant profile.
Urban or rural?
Urban or rural status comes from where the library is located, using the classification USAC applies. Rural libraries get a higher discount in the lower bands.
Tribal libraries
Tribal libraries have their own rules, including a higher Category 2 discount cap and a higher Category 2 budget floor. Check current USAC guidance.

What E-Rate pays for in a library
Services fall into two categories. The split matters because each has its own discount cap, its own budget rules and its own link to CIPA.
Category 1: getting data to the building
- Internet access from a provider
- Data transmission and wide area connections between branches
- Fiber builds in some cases, with extra rules
- Discount up to 90%, no fixed library budget
Category 2: the network inside
- Wifi access points, switches, routers and cabling
- Basic firewall services that are part of the network
- Managed internal broadband and basic maintenance
- Discount up to 85%, capped by the square-foot budget
Content filtering, end-user devices and staff training are generally not eligible. Check the current eligible services list each year, because it changes.
How library traffic is labelled
Patrons use a mix of reference, jobs and government services, and the data separates them cleanly.

The library Category 2 budget, per square foot
Category 2 covers the network inside the building: wifi access points, switches, cabling, managed internal broadband and basic maintenance. Schools get a budget per student; libraries get one per square foot.
Your estimate for FY2026 to FY2030
Uses the FY2026 to FY2030 figures announced by the FCC: $5.43 per square foot, a $30,175 minimum, and a $66,385 minimum for Tribal libraries. An estimate only, not a USAC calculation.
Square footage is validated with USAC, generally in the first year you request Category 2 support in the cycle, and it sets the budget for the five years. Measure carefully and keep the floor plans or records that support the figure.
When CIPA applies to a library's E-Rate
CIPA is attached to specific services, not to E-Rate as a whole. Many small libraries are surprised to learn that a telephone-only application does not trigger it.
CIPA applies if you receive discounts on
- Category 1 internet access
- Category 2 internal connections, such as wifi and switches
- Managed internal broadband services
- Basic maintenance of internal connections
CIPA does not apply if
- You receive E-Rate discounts only for telecommunications services
- You do not take E-Rate or LSTA funds tied to internet access at all
State law may still require filtering or a policy. Check your state's rules separately.
The three CIPA certifications a library can make
We comply
The filter is in place, the internet safety policy is adopted after public notice and a hearing, and it is enforced.
We are undertaking actions
Available in your first funding year only. You are working toward compliance, for example still procuring a filter.
CIPA does not apply
You receive discounts only for telecommunications services, so the CIPA conditions are not triggered.
A waiver for the second funding year exists only in narrow cases, such as state or local procurement rules preventing compliance. It is not available simply because the library is not ready. Details of each form are in our guides to Form 486 CIPA certification and Form 479 for consortium members.
Applying alone or through a consortium
Many libraries get internet access through a state library network, a regional system or a joint purchase with schools. That changes who files what.
- The library posts Form 470 and runs its own bid process.
- It files Form 471 in the window, for its own buildings.
- After the funding decision, it files Form 486 within the deadline.
- On Form 486, the library certifies its own CIPA status.
- It keeps the CIPA evidence: policy, notice, hearing minutes and filter records.
- The library signs a letter of agency so the consortium can apply for it.
- The consortium lead files the 470, 471 and 486 as billed entity.
- The library's board certifies its CIPA status on Form 479.
- The library gives the signed Form 479 to the consortium lead before the lead files Form 486.
- The library still holds its own CIPA evidence, because compliance is local.
A consortium cannot be CIPA compliant for you. It can supply a filtered connection, but the internet safety policy, the public hearing and the adult unblocking procedure belong to your library and your board.
Deadlines and pitfalls libraries hit most
E-Rate is unforgiving about dates. These are the moments where small library teams most often lose money.
Form 486 filed late
Form 486 is due 120 days after the service start date or 120 days after the funding commitment decision letter, whichever is later. If it is late, USAC moves the start date forward, and service before that date is not funded.
Wrong school district in the profile
The discount follows the school district in your applicant profile. If the district is wrong, the discount is wrong, and corrections take time. Check it each year before the filing window.
Treating the consortium connection as full compliance
Even if the network you share is filtered upstream, your library still needs its own adopted policy, its own public hearing record, and a way for adults to get unfiltered access.
Policy adopted without a hearing
The internet safety policy must be adopted after reasonable public notice and at least one public hearing or meeting. A board vote alone, with no notice, leaves a gap reviewers notice.
Square footage that cannot be supported
The Category 2 budget rests on the square footage you report. Use measured figures and keep the floor plans or facility records behind them.
Planning around hotspot lending
The FCC added library hotspot lending to E-Rate in 2024 and voted to remove it in September 2025. Build any off-site connectivity plan on other funding, and check the current eligible services list.
A library E-Rate year, season by season
The E-Rate funding year runs from July 1 to June 30. Work for a given year starts many months earlier, so small libraries usually juggle two years at once.
Late summer and autumn
Review what you will need next year. Update your applicant profile, confirm your school district and check square footage.
Winter
Post Form 470, wait at least 28 days, evaluate bids and sign contracts. The Form 471 window usually opens in winter; check USAC for the dates.
Spring
Answer USAC review questions quickly. Funding decisions begin to arrive. Review your internet safety policy before the new year starts.
Summer
Services start on or after July 1. File Form 486, or collect Form 479 for your consortium, and start invoicing.
Who does what in a small library
| Task | Director | Board | IT lead or vendor | E-Rate consultant or state coordinator |
|---|---|---|---|---|
| Decide what services to request | Leads | Approves budget | Advises | Advises |
| Form 470 and bid evaluation | Leads | Informed | Writes specs | Checks process |
| Form 471 filing | Signs | Informed | Supplies details | Often prepares |
| Internet safety policy and hearing | Drafts | Adopts | Confirms filter matches | Reviews wording |
| Form 486 or Form 479 | Signs | Authorizes | Confirms service start | Tracks deadline |
| Filter settings and adult bypass | Approves | Sets policy | Configures | Not involved |
| Records folder | Owns | Minutes | Exports and reports | Checklist |
Many state library agencies run E-Rate help for public libraries, including training and filing support. Ask yours before hiring outside help, and use the table to agree who owns each step.
Your library's E-Rate and CIPA records pack
Keep one folder per funding year. E-Rate document retention rules are long, currently ten years after the last date of service, so confirm the current rule with USAC and file accordingly.
Adopted policy
The internet safety policy as approved, with the date of adoption.
Public notice
The dated notice of the meeting where the policy was discussed.
Hearing minutes
Agenda and minutes showing public comment was possible.
Filter evidence
Contract or service record and a settings export for the year.
Adult bypass procedure
The written steps and the list of authorized staff roles.
Forms and letters
Copies of 470, 471, 486 or 479, the FCDL and any letters of agency.
Bid records
Bids received, the evaluation matrix and the reason for the choice.
Square footage
The figures and documents behind your Category 2 budget.
Our guide to what USAC asks for in a CIPA audit shows how reviewers use these records, and the CIPA compliance checklist turns them into a yearly task list.
Patron devices outside your control
The filter works at the network, so devices you do not own are covered when they join the wifi. Nothing is installed on computers.
Choosing a filter that fits library E-Rate
Filtering itself is generally not an E-Rate eligible service, so most libraries pay for it from their own budget. That makes a simple, low-maintenance option attractive.
Covers every funded connection
Public PCs, staff computers and public wifi on the same connection, without software on each device.
Adult bypass at the desk
Authorized staff can disable filtering for an adult quickly, and it switches back on by itself. See CIPA adult unblocking in libraries.
Records for the folder
Printable reports of the categories in force and of bypass use, without recording what adults read.
Our hosted CIPA filter is a DNS filter run for you, with a CIPA preset, per-branch settings and a staff PIN bypass. Libraries comparing approaches can also read web filtering for libraries and our public library internet filtering policy guide.
Pick a library filter
What libraries weigh up
| Consideration | Typical approach | Hosted CIPA filter |
|---|---|---|
| Branches | Separate boxes | One console, separate settings per branch |
| Adult requests | Disable the filter | Logged staff PIN |
| Patron devices | Hard to reach | Filters at DNS, nothing installed |
| Record keeping | Manual notes | Reports, policy record, log export |
| Upkeep of lists | In-house work | Run for you |
E-Rate for libraries FAQ
Can a public library get E-Rate discounts?
Yes, if it meets the Library Services and Technology Act definition of a library, is eligible for assistance from its state library administrative agency, and has a budget separate from any school. Check eligibility with your state library agency.
How is a library's E-Rate discount calculated?
A library uses the student poverty level of the public school district where it is located, or where the main branch of a library system is located, plus its urban or rural status. Category 1 discounts run from 20 to 90 percent and Category 2 from 20 to 85 percent, with higher Category 2 caps for Tribal libraries.
What is the library Category 2 budget for FY2026 to FY2030?
For the FY2026 to FY2030 cycle, the FCC set the library multiplier at 5.43 dollars per square foot, with a minimum budget of 30,175 dollars, and a higher floor for Tribal libraries. The budget is pre-discount. Confirm current figures with USAC.
Does CIPA apply if we only get discounts on telephone service?
No. CIPA applies when a library receives E-Rate discounts for internet access or Category 2 internal connections services. A library that receives discounts only for telecommunications services can certify that CIPA does not apply.
Which form does a library use to certify CIPA?
A library that applies for itself certifies on FCC Form 486. A library that is a member of a consortium certifies on FCC Form 479 and gives it to the consortium's billed entity, which then files Form 486.
Can libraries still get E-Rate support for lending wifi hotspots?
No. In September 2025 the FCC voted to end E-Rate support for hotspot lending that it had added in 2024. Check USAC for the current eligible services list before planning any off-site connectivity.
What if we are applying for the first time and are not yet CIPA compliant?
In the first funding year, a library can certify that it is undertaking actions to comply with CIPA. From the following year it must be fully compliant, with only narrow waiver options.
Is a web filter itself eligible for E-Rate discounts?
Generally no. Content filtering is not on the eligible services list, so libraries usually pay for the filter from their own budget, even though CIPA requires one when E-Rate covers internet access or internal connections.
