Am I supposed to get an acknowledgement letter after I file a FOIA request, and what should it contain?

The Short Answer

Yes. Under the federal Freedom of Information Act (FOIA), agencies routinely send an acknowledgement after they receive your request. This letter (or email) confirms that your request arrived and entered the agency’s processing queue. It is a normal, early step — not a decision on whether your records will be released.

Keep in mind that the FOIA covers only federal agencies. State and local public-records laws have their own rules, and whether an acknowledgement is required varies by jurisdiction.

What an Acknowledgement Letter Typically Contains

A useful federal acknowledgement letter generally includes:

• A tracking or reference number. This is the most important item. Use it in every follow-up so the agency can locate your request quickly.
• The date the request was received. This date matters because the FOIA generally gives agencies 20 business days to determine whether they will comply.
• A restatement of what you asked for. Confirm this matches your intent; if the agency misread the scope, say so promptly.
• Contact information for the FOIA office or the analyst assigned to your request.
• Fee information, such as your fee category, any fees you may owe, and how to request a fee waiver.
• Notice of any complications, such as a need to clarify the request, search a different component, or invoke an extension for “unusual circumstances.”

Why It Matters

The acknowledgement starts your paper trail. Save it. If the response runs long, the tracking number lets you check status, escalate, or seek help. Many agencies also list a FOIA Public Liaison you can contact, and the Office of Government Information Services (OGIS) offers dispute-resolution assistance.

If You Do Not Receive One

Practices differ across agencies, and a missing acknowledgement does not by itself mean your request was ignored — but it is worth confirming receipt. Reach out to the FOIA office, reference your submission date, and ask for your tracking number. Keep copies of everything you send and receive.
