How to Legally Move with a Suppressor: Complete Relocation Guide

• You can move with a suppressor within your state without notifying the ATF if your tax stamp is current.
• Moving out of state requires either Form 5320.20 (temporary relocation) or a new registration if you're permanently relocating.
• Some states prohibit suppressors entirely, requiring you to store them outside the state or transfer to a dealer.
• Your NFA tax stamp is tied to the registration record in the National Firearms Registration and Transfer Record (NFRTR), which must be kept current.
• If your Form 4 is pending, you can move in-state freely, but out-of-state moves may require notification depending on your situation.
   

Moving with a suppressor isn't complicated, but it's not something you can just ignore either. The ATF has specific rules depending on whether you're moving across town or across the country, and whether your destination allows suppressors at all. This guide breaks down your obligations state by state, walks you through Form 5320.20, and explains what happens if your Form 4 is still pending when you move. The core rule is simple: in-state moves require no action, but out-of-state moves and prohibited-state relocations demand planning.

You're not the first person to move with an NFA item, and you won't be the last. The ATF has clear guidance, and we've broken it down into the scenarios most people actually face: moving down the street, moving to a different state, moving somewhere suppressors are illegal, and what to do if your paperwork hasn't cleared yet.

 
NOTE: This is not intended as legal advice; state laws continually change so please review the current law in your state, or in the state you might be traveling to, and please consult with a licensed attorney in that state.

If you're moving within the same state, you don't need to notify the ATF. Your tax stamp doesn't care about your address change as long as you remain in a suppressor-friendly state. Your NFA registration stays active. The only thing that might matter is if your state requires you to re-register NFA items with local law enforcement when you relocate (a handful of states do this). Contact your local Sheriff's office before the move to confirm whether your state has a re-registration requirement. If it does, handle that at the same time you handle your civilian property move. That's it. In-state moves are straightforward because your tax stamp's legal validity doesn't change with your address.

Out-of-state moves are where the ATF wants to know your business. Before you move, verify that suppressors are legal in your destination state. Most of the U.S. allows them, but a handful don't. Check our suppressor laws by state guide to confirm your destination is a suppressor-friendly state. If it is, here's what you need to do: Notify the ATF using Form 5320.20. For suppressors specifically, filing is recommended but not legally required before you move (unlike SBRs and other NFA firearms, which require prior approval). That said, filing before or shortly after your move is the smart play.

This form tells the ATF your new address, confirms your tax stamp is still valid, and updates the National Firearms Registration and Transfer Record (NFRTR) with your new location. The NFRTR is the ATF's central database of all registered NFA firearms. Your registered suppressors are listed there under your name, address, and tax stamp number. Keeping this record current is not just a formality, it's required for compliance. If you move and don't update NFRTR, your registration becomes inaccurate, which could cause issues if you're ever contacted by law enforcement or if you need to travel with your suppressor later.

How to File Form 5320.20

Filing Form 5320.20 is straightforward. You can submit it either electronically (preferred) or by mail. Here's what the form requires:

1. Your current address and your new address

2. Your tax stamp number (this is on your approved Form 4)

3. Your suppressor's serial number and make/model

4. A statement about the reason for the move (permanent relocation, temporary relocation, or travel)

5. Your signature

To file electronically, visit the ATF's firearms forms page, download Form 5320.20, fill it out, and email the completed form to NFAFAX@ATF.GOV. Include your full legal name and phone number in the email body. The ATF typically processes these forms within 1-2 weeks, though current processing times can vary.

If you prefer to mail it, you can print and send it to the address listed on the form itself, but expect 2-4 weeks for mail processing. Keep a copy of the submitted form and the ATF's confirmation for your records. If you move to a state that requires NFA registration with local authorities, you'll want to have the ATF's confirmation on hand.

Why NFRTR Updates Matter

The National Firearms Registration and Transfer Record (NFRTR) is the ATF's official registry of all NFA firearms in civilian hands. Every registered suppressor, SBR, and machine gun has a record there. When you move out of state, updating your address in NFRTR is the legal requirement, and it's handled through Form 5320.20.

This keeps the ATF's records accurate so that if you're contacted by law enforcement, checked at a checkpoint, or need to transport your suppressor across state lines, your documentation matches the official record. Mismatches between your actual address and NFRTR can complicate compliance, even if the discrepancy is innocent. Staying current is just smart filing.

Transporting a Suppressor Across State Lines

Transporting across state lines and permanently relocating are different situations, but both require ATF notification. If you're moving from Florida to Georgia, you need Form 5320.20. If you're temporarily traveling to another state for a vacation or business trip, you have different options. See the "Moving vs Traveling" section below for the distinction. For permanent or long-term relocation, assume you need Form 5320.20 unless your situation falls clearly into temporary travel (a few days, specific event, known return date). When in doubt, file the form. The processing is quick enough that it's not worth guessing on compliance.

Eight states plus Washington D.C. prohibit civilian suppressor ownership. If you're moving to one of these states, you have limited options. Your suppressor cannot move with you. Here's the list of prohibited states: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, Rhode Island, and Washington D.C. If your destination is on this list, you have three realistic paths forward:

Option 1: Store your suppressor outside the state. Many people keep their suppressors with a family member or trusted friend in an adjacent state, or rent a safe deposit box at a bank in a suppressor-friendly state. This is legal as long as you're not possessing it in the prohibited state. The suppressor remains registered in your name via NFRTR, and you can retrieve it when you leave.

Option 2: Rethink the move. If suppressors are a core part of your shooting hobby or collection, staying in a suppressor-legal state might be worth the consideration. This is a personal decision, but it's worth weighing.

Option 3: Dispose of or sell your suppressor before the move. You can sell it to a licensed dealer or private collector in a suppressor-legal state, or you can surrender it to local law enforcement. Selling requires transferring ownership, which involves a new Form 4 application by the buyer. Surrendering it means you lose the suppressor and the remaining value of your tax stamp, but it's clean and straightforward.

Do not attempt to move a suppressor into a prohibited state. The penalties include federal prosecution, forfeiture of the suppressor, and potential loss of your firearms privileges. It's not worth it.

Your Form 4 is in the ATF's queue. You're approved, but the tax stamp hasn't arrived yet. Now you're moving. What happens?

If you're moving in-state, keep moving. Nothing changes. Your Form 4 status isn't affected by a state-level address change.

If you're moving out of state while your Form 4 is pending or recently approved, things get more complicated. The safest approach is to wait until your tax stamp arrives before you move. Your approved Form 4 will be issued to your current address. Once it arrives, you can then file Form 5320.20 to update your address. If you absolutely must move before the stamp arrives, contact the ATF directly at NFAFAX@ATF.GOV before you relocate. Explain your situation (job transfer, home sale deadline, etc.) and provide your new address. The ATF can sometimes update your Form 4 address before issuance, but this requires advance notice and their approval. Don't assume it will work; ask first.

Your Moving Checklist for NFA Items

Before you move out of state with a suppressor, confirm these boxes are checked:

1. Confirm your destination allows suppressors (check state laws at our suppressor laws by state page).

2. Gather your Form 4 approval letter and tax stamp number.

3. Collect the serial number and make/model of your suppressor.

4. Download Form 5320.20 from the ATF's website.

5. Fill out the form with your current address, new address, and suppressor details.

6. Email the completed form to NFAFAX@ATF.GOV at least one week before your move date.

7. Wait for ATF confirmation (typically 1-2 weeks).

8. Keep the ATF's confirmation email with your moving documents.

9. If your state requires local NFA registration, contact your Sheriff's office with the ATF confirmation.

If you're a frequent mover (military, job transfers, business relocation), keep your Form 5320.20 well-organized and file it as soon as relocation is confirmed. The ATF expects to see these forms, and quick filing prevents any compliance gaps if you're audited or contacted during a move.

Form 5320.20 is the official ATF document for notifying the agency of a permanent or long-term relocation with NFA items. It's available on the ATF's website as a free download. You have two submission options: electronic or mail.

Electronic submission (preferred): Complete the form, scan it, and email it to NFAFAX@ATF.GOV. Include your name and phone number in the email body so the ATF can contact you if questions arise. Response time is typically 1-2 weeks.

Mail submission: Print the form, sign it, and mail it to the address listed at the bottom of Form 5320.20. Include a copy of your Form 4 approval letter and your tax stamp number in the envelope. Response time is typically 2-4 weeks, sometimes longer depending on mail volume.

Most people choose electronic submission because it's faster and you have a timestamp of when the ATF received it. Either way, keep the ATF's response or confirmation email with your records.

Moving vs. Traveling with a Suppressor

This distinction matters because the ATF treats permanent relocation and temporary travel differently, and your obligations change depending on which one you're doing.

Moving (permanent or long-term relocation): You're changing your primary residence to a different state and don't plan to return to your previous state. The ATF recommends filing Form 5320.20. For suppressors, you can file before or after the move (it's not legally required in advance like it is for SBRs). Filing before you move is the best practice.

Traveling (temporary, short-term, or planned return): You're going on vacation, attending a shooting event, or traveling for business with a known return date to your home state. Temporary travel doesn't require Form 5320.20 if you're coming back. However, if you're gone for more than a few weeks or your travel is indefinite, the ATF may view it as relocation. The safe rule: if you're gone for more than 30 days, consider filing 5320.20. If you're unsure whether your situation is travel or relocation, file the form. It's the conservative approach and doesn't hurt. Our traveling with a suppressor guide covers temporary transport in more detail.

The key difference is intent and duration. A weekend shoot in another state is travel. A job transfer lasting six months is relocation. A seasonal move or long-term project is relocation. When in doubt, treat it as relocation and file 5320.20.

Moving with a silencer, or while a silencer is pending approval, doesn’t have to be scary. We’re here to make the NFA process as simple as possible and to give you all of the information you need to be a well-informed suppressor owner. In most cases, there is nothing for you to do when moving with a silencer, no forms, no documents, no headaches. In the instance that you’re moving to a new state, or to a prohibited state, there is a little more work to do. An NFA trust can be useful for keeping the silencer in a legal state.

Is there an ATF change of address form for suppressors?

Yes. Form 5320.20 is the official ATF form for notifying the agency of a change of address when you're moving out of state with NFA items, including suppressors. It's available free on the ATF's website and can be submitted electronically or by mail.

Do I need a 5320.20 to transport a suppressor across state lines?

It depends on whether you're moving or traveling. If you're permanently relocating to another state, you need Form 5320.20 before you move. If you're temporarily traveling to another state with a planned return date, you don't need 5320.20 for travel under 30 days. For anything longer or if your intent is relocation, file the form. See the "Moving vs Traveling" section for clarification.

What’s different if I own an SBR or other NFA firearm?

The process is the same for suppressors, but different NFA items have different rules about when you can file. For suppressors, you can file Form 5320.20 after you move. For SBRs and SBSs (short-barreled shotguns), you must file before you move or you'll be in federal violation. Machine guns have additional restrictions. If you own multiple NFA items, confirm the filing timeline for each item type before your move.

What if I’m moving to a state with different suppressor laws?

First, verify your destination allows suppressors using our suppressor laws by state page. If it does, proceed with Form 5320.20 filing. If it doesn't, you'll need to store your suppressor outside the state, sell it, or surrender it. Don't attempt to move a suppressor into a prohibited state.

Will moving in-state affect my pending Form 4?

No. In-state moves don't affect your Form 4 status. You can move freely within your state while waiting for approval. If you're moving out of state while your Form 4 is pending, contact the ATF before relocating to request an address update on the pending Form 4.

Does my NFA trust need updates when I move?

Your trust document itself doesn't need updating. However, if your trust is registered with the ATF as the responsible person for your NFA items, the address on file should be updated through Form 5320.20. Confirm with a trust attorney whether your specific trust structure requires any internal updates, though most don't.

Where should I keep my tax stamp when moving?

Keep your tax stamp and Form 4 approval letter in a safe location during the move, not in a vehicle. The stamp is proof of lawful registration. If it's lost during a move, you can request a replacement from the ATF, but the process takes time. Store it with your important documents. You don't need to surrender it to the ATF during a move, only submit Form 5320.20 to update your address.

Do I have to notify the ATF if I move in-state with a suppressor?

No. In-state moves don't require ATF notification. Your tax stamp remains valid regardless of your address within the same state, as long as the state allows suppressors. You don't need Form 5320.20 for in-state relocations. Some states do require local law enforcement notification, so check with your local Sheriff's office before moving.

How long does it take for the ATF to process Form 5320.20?

Electronic submission typically takes 1-2 weeks. Mail submission typically takes 2-4 weeks. Current processing times can vary, so submit your form as early as possible before your move date. The ATF will send a confirmation email or letter acknowledging receipt.

What is NFRTR and why does my address matter?

NFRTR (National Firearms Registration and Transfer Record) is the ATF's central database of all registered NFA firearms in civilian hands. Your suppressor is listed there with your name, current address, and tax stamp number. Keeping this record current through Form 5320.20 updates ensures the ATF's records match your actual location, which is required for compliance. Mismatched records can cause issues if you're contacted by law enforcement or need to travel with your suppressor.
