The 28-day waiting period is the minimum time FCC rules require applicants to wait after certifying their FCC Form 470 before selecting a service provider, signing any contract, or submitting a Form 471. The day of certification counts as day one, and EPC (the E-Rate Productivity Center) tracks the waiting period automatically.
How It Works
The clock starts the calendar day you certify your Form 470 in EPC, including weekends and holidays. That day is day one. USAC's own example: certify on January 1, and the earliest date you can sign a contract, the Allowable Contract Date, is January 29 (USAC: 28-Day Waiting Period).
Applicants can set a later bid deadline in their Form 470 narrative or RFP. That deadline must still be at least 28 days after certification, or longer if state or local procurement rules require it. If no deadline is set, applicants should consider all bids received right up until they begin evaluating them.
Only minor corrections to a certified Form 470 leave the clock alone. Starting in Funding Year 2025, a substantive correction can be made by attaching a new RFP to the already-certified Form 470, and EPC automatically recalculates a fresh 28-day period from that point. Automated or spam bids that don't include pricing information can be disqualified as non-responsive without extending the window, though applicants should keep a record of why each one was disqualified.
What This Means for You
Applicants
Certifying your Form 470 starts a real, EPC-tracked clock. Build your procurement timeline around the certification date, not the date you finished drafting the form, and think twice before making a "quick correction" late in the process if it might qualify as substantive.
Service Providers
You cannot be selected, and no contract can be signed, until the applicant's 28 days have run. Pushing an applicant to move faster than the rule allows creates a documentation problem for both of you if it's ever reviewed.
The mistake we see most often isn't ignorance of the 28-day rule itself, it's applicants assuming the clock starts when they finish writing the Form 470, not when they actually certify it in EPC. Those two moments can be a week or more apart, and that gap has quietly blown procurement timelines for districts who thought they were already clear to sign.
Common Questions About the 28-Day Waiting Period
When does the 28-day clock start?
The calendar day you certify your Form 470 in EPC counts as day one, including weekends and holidays.
Can I sign a contract before the 28 days are up?
No. The earliest you can sign is the Allowable Contract Date, which falls 28 days after certification.
What happens if I set a later bid deadline?
You still have to wait at least 28 days from certification, or longer if your own stated bid deadline, or your state or local procurement rules, require more time.
Does correcting my Form 470 restart the waiting period?
Only for substantive corrections. Minor fixes leave the original clock in place, but a substantive change with a new RFP attached to the certified 470 (allowed starting Funding Year 2025) triggers a new, automatically recalculated 28-day period.
Do I have to consider every bid I receive?
Yes, up until you begin your evaluation, unless you set and documented a specific bid deadline in your Form 470 or RFP. Automated or spam bids without pricing information can still be disqualified as non-responsive.
