The E-Rate Form 470 Timeline: Deadlines, the 28-Day Rule, and the Allowable Contract Date

E-Rate competitive bidding runs on a sequence with real legal consequences. File a contract one day too early, miss the Form 471 window by a week, or miscount the 28 days, and USAC can deny the funding request. For service providers trying to time outreach, proposals, and contract execution, understanding that sequence is not optional.

This guide explains the causal chain from Form 470 posting through Allowable Contract Date through Form 471 window, with worked examples and a look at what FRNHQ's own Form 470 data reveals about how applicants actually use it.

What Is the E-Rate Form 470, and Why Does It Start the Clock?

The Form 470 (formally the "Description of Services Requested and Certification Form") is the public notice an applicant must post before selecting a service provider or signing an E-Rate-funded contract. It's a mandatory prerequisite. No Form 470, no funding.

When an applicant certifies their Form 470 in USAC's E-Rate Productivity Center (EPC), two things happen simultaneously: the posting goes public (any provider can see it and bid), and the 28-day clock starts.

That clock is the governing constraint on everything downstream. Form 471 cannot be filed, contracts cannot be signed, and provider selection cannot be finalized until the window runs its course. The Form 470 is not a formality that gets filed and forgotten. It is the legal starting gun for the entire competitive bidding process. For a deeper look at what the form contains and how providers screen it for viable bids, the Form 470 explained guide covers the mechanics.

The 28-Day Rule: What It Means, How to Count It, and Why It Exists

The 28-day waiting period exists because E-Rate is a federal program that requires genuine competitive bidding. Without a mandatory window, applicants could post a Form 470, call their preferred vendor that afternoon, and sign a contract the next day. The 28 days force a real opportunity for competing providers to see the posting and respond.

How to count it:

Day 1 is the day the Form 470 is certified in EPC, not the day the applicant started filling out the form.
Weekends and federal holidays count. This is 28 calendar days, not 28 business days. A Form 470 certified on a Friday counts that Friday as Day 1.
If the applicant also issues a separate RFP after the Form 470 is posted, the 28-day window restarts from whichever date is later: the Form 470 certification date or the date the RFP became publicly available.

That last point catches providers off guard. An applicant can post a Form 470 in December, release a detailed RFP in January, and the ACD resets to the later RFP date. If you are tracking ACD timing from the Form 470 date alone, you may be calculating wrong.

Calculating Your Allowable Contract Date: A Worked Example

The Allowable Contract Date (ACD) is the first day an applicant can legally sign a contract, select a provider, or submit their Form 471. It is Day 29 relative to the Form 470 certification date.

The arithmetic is simple but the off-by-one error is common:

Form 470 certified: January 1 Day 1 = January 1 Day 28 = January 28 Allowable Contract Date = January 29

The applicant cannot sign anything on January 28. January 29 is the first day a contract execution is valid for E-Rate purposes.

This matters for providers because you should not be asking applicants to sign before their ACD. A contract executed before the ACD is a compliance violation that can invalidate the entire funding request. If an applicant tells you they want to sign this week and you know their Form 470 was posted ten days ago, the correct response is to flag the issue, not to proceed.

USAC sends applicants an EPC Receipt Notification Letter that includes the computed ACD. That letter is the applicant's authoritative reference. If the ACD in the letter and your own count disagree, defer to the letter.

How the Form 470 Timeline Connects to the Form 471 Filing Window

The Form 471 is the actual funding request. It names the selected provider, describes the services, and generates the Funding Request Number (FRN) USAC uses to track and commit funds. Applicants cannot file the Form 471 until after their ACD.

For FY2026, the Form 471 filing window opened January 21, 2026 at noon Eastern and closed April 1, 2026 at 11:59 p.m. Eastern. That window is hard. Late filings are not accepted.

Work the sequence backwards from the window close date:

April 1, 2026: Form 471 window closes.
March 4, 2026: Last possible date to certify a Form 470 and still have the 28-day window expire before the Form 471 deadline.
January 21, 2026: Form 471 window opens (applicants with earlier ACDs can start filing immediately).

A Form 470 certified on March 5, 2026, would have an ACD of April 2, one day after the Form 471 window closed. That applicant could not file a Form 471 for FY2026. The whole year's funding opportunity is gone.

For comparison, FY2025 ran on a slightly earlier schedule: the last valid Form 470 date was February 26, 2025, and the Form 471 window closed March 26, 2025.

The E-Rate filing deadlines calendar tracks the FY-specific dates in one place if you need to confirm numbers for multiple funding years.

FY2026 Key Dates at a Glance

Milestone	FY2026 Date
Form 470 may be filed (no formal open date)	Any time; best practice: early November 2025
Form 471 window opens	January 21, 2026
Last valid Form 470 certification date	March 4, 2026
Form 471 window closes	April 1, 2026
FY2026 funding cap	$5.2 billion

On May 11, 2026, the FCC announced that USAC will fully fund all eligible Category 1 and Category 2 requests for FY2026. Projected total demand is approximately $3.5 billion ($1.7B Category 1, $1.8B Category 2) against a $5.2 billion cap. For FY2026, proration is not a concern, but that is not always the case, and filing early still matters for getting commitments issued ahead of the budget cycle.

What Happens If You Miss the 28-Day Window?

If an applicant signs a contract before their ACD, USAC will deny the funding request when it discovers the violation during PIA (Program Integrity Assurance) review. The denial is typically not appealable on this point: the rule is bright-line. There is no grace period, no cure process for a contract that was executed one day early.

The practical effect for providers: if you are under pressure from an applicant to move faster than their ACD allows, you are not doing them a favor by accommodating it. You are helping them lose the funding. The 28-day rule is designed to protect both parties.

There is one narrow exception worth knowing. If USAC itself makes an error in the EPC system that causes the 28-day period to be computed incorrectly in the applicant's notification letter, applicants can raise that in a waiver request. But a miscounted calendar by the applicant or provider does not qualify.

Multi-Year Contracts: When Can You Skip the Form 470 in Future Years?

A multi-year contract does not require a new Form 470 for every year it covers, as long as the original contract resulted from a proper competitive bidding process and the contract terms specify the extension options precisely.

The conditions:

The original contract must have covered the competitive bidding requirements fully when it was signed (a valid Form 470, a proper 28-day window, ACD-compliant execution).
The contract itself must spell out the renewal or extension terms. A generic "may be extended by mutual agreement" clause does not qualify. The contract needs to state the specific extension period and terms that were available to bidders at the time of the original solicitation.
The services being continued must be the same services covered by the original Form 470. Adding new service categories or materially different services requires a new competitive bidding cycle.

When those conditions are met, the applicant files the Form 471 in subsequent years referencing the original contract and its extension, without repeating the Form 470 process. This is a meaningful time and administrative savings for applicants with large, stable service footprints. For providers, it is also the basis for a defensible multi-year contract: once you have been properly selected, you are protected from rebid as long as the contract terms hold.

The flip side: when a multi-year contract expires or is not properly extended, the district must rebid. That is the signal providers who are not the incumbent should be watching for. FRNHQ's Re-bid Radar surfaces exactly this pattern from our FY2016-FY2026 FRN data, flagging contracts approaching the end of their covered period.

How Early Should You File? What FRNHQ's Form 470 Data Shows

There is no formal opening date for Form 470 filings. Applicants can file at any point in the year for any upcoming funding year. In practice, the distribution is heavily weighted toward a few months.

FRNHQ indexes 286,746 Form 470 records across FY2016 through FY2026. The filing pattern is consistent across years:

The largest share of Form 470 filings concentrates in November and December, as applicants work to post early enough to give providers a meaningful bidding window before the Form 471 season opens in January.
A second, smaller cluster appears in January and February, filed by applicants who are behind on their timeline or who waited to see whether the Form 471 window dates were announced as expected.
A thin tail of filings runs through March, concentrated among applicants who either have simple procurement needs or are catching a last-minute RFP from a board approval cycle.

The implication for providers is that November through January is when the majority of new biddable opportunities enter the pipeline. Prospecting on Form 470s during this window, before ACDs have passed and before Form 471 season is over, gives you the widest possible runway to respond to solicitations and have conversations before applicants commit to a provider.

A Form 470 posted in March with a late-March ACD gives you almost no time to respond meaningfully. Those are not where you build a pipeline. The early-cycle 470s are the opportunities worth prioritizing.

Common Mistakes That Blow the Allowable Contract Date

Most ACD violations are not deliberate. They come from a handful of recurring errors:

Counting business days instead of calendar days. The 28-day period runs on calendar days. A provider that tells an applicant "four weeks from your posting date" is correct in spirit but wrong if the applicant mentally converts that to four business weeks.

Starting the count from the wrong date. Day 1 is the EPC certification date, not the date the applicant started preparing the form, not the date you received a copy of it, not the date it appeared in a third-party database. There can be a lag between EPC certification and when the posting shows up in downstream data. Always confirm the actual certification date.

Ignoring a subsequent RFP. If the applicant issued any formal RFP documentation after the Form 470 was posted, the ACD is calculated from that later document, not from the Form 470. Many providers track Form 470 posting dates but miss the RFP release date that resets the clock.

Signing a letter of intent. A letter of intent, memorandum of understanding, or any written commitment to a provider signed before the ACD can be treated as an early contract execution by USAC during review. Nothing binding should go on paper before the ACD, even if it is positioned as preliminary or conditional.

Frequently Asked Questions: E-Rate Form 470 Deadlines and the ACD

Can an applicant file their Form 471 on the same day as their ACD?

Yes. The ACD is the first day they can sign a contract and file the Form 471. There is no additional waiting period after the ACD.

Does the Form 470 expire if the applicant does not file a Form 471 in the same funding year?

Yes, effectively. A Form 470 is specific to a funding year. If the applicant does not file a Form 471 for that funding year before the window closes, they would need to post a new Form 470 for the next funding year and run the 28-day process again.

What if an applicant wants to change the scope of services after posting the Form 470?

Minor clarifications are generally handled through the RFP process or bidder Q&A. Material changes (adding a service category, changing the eligible service type) typically require a new Form 470.

Is there any way for a provider to know when an applicant's ACD has passed without a 471 being filed?

Yes, if you have the Form 470 certification date, you can compute the ACD directly. A past-ACD Form 470 with no associated Form 471 in USAC's data is an applicant who evaluated bids and either is still deciding or had no responsive bids. That is a sales conversation worth having.

FRNHQ's Form 470 lead tools filter biddable opportunities by state, service category, and ACD timing, so you can identify exactly which postings are still in window and which have passed without a filed 471. The E-Rate hub gives you the broader state-level funding picture, and Texas E-Rate activity is a sample of the state-level depth available. See open Form 470s and filter by ACD timing inside FRNHQ.
