Uploading fingerprints to ATF eForms can be confusing if you've never done it before. This tutorial walks you through the exact process, step by step, so you know exactly where to click and what to expect.
Before You Start: Make sure you have your EFT file ready. The ATF only accepts .eft format files—not images, PDFs, or scanned documents. Need to convert your FD-258 card? Use SlapEFT.
In This Tutorial
What You Need Before Starting
- ATF eForms account: Register at eforms.atf.gov
- Draft Form 1 or Form 4: Create your application if you haven't already
- EFT fingerprint file: Your .eft file from SlapEFT or another conversion service
- Modern browser: Chrome, Firefox, or Edge (not Internet Explorer)
Step 1: Log Into ATF eForms
- Go to eforms.atf.gov
- Click "Sign In" in the top right corner
- Enter your username and password
- Complete any multi-factor authentication if prompted
Once logged in, you'll see your eForms dashboard with any draft, submitted, or approved applications.
Tip: If you don't have an account yet, click "Register" and follow the prompts. You'll need to verify your email address before you can create applications.
Step 2: Open Your Draft Application
For New Applications
- Click "Create New Application"
- Select Form 1 or Form 4 depending on your needs
- Fill out the initial sections (applicant info, firearm info, etc.)
- Save your draft periodically
For Existing Drafts
- Find your application in the "Drafts" section
- Click on the application to open it
- Continue where you left off
Step 3: Navigate to the Fingerprints Section
The fingerprint upload location varies slightly between Form 1 and Form 4, but the process is similar:
Form 1 (Making a Firearm)
- Navigate to Section 4: "Responsible Person"
- If individual: your info will be listed
- If trust: each responsible person will be listed
- Find the "Fingerprints" field for each person
Form 4 (Transferring a Firearm)
- Navigate to Section 12: "Transferee Information" (if individual) or Section 13 (if trust)
- Scroll to the fingerprint section
- Find the "Electronic Fingerprints" upload area
Trust Applicants: Each responsible person on the trust must have fingerprints uploaded. You'll see an upload button for each person listed.
Step 4: Upload Your EFT File
- Click the "Upload" or "Browse" button next to the fingerprints field
- Navigate to your EFT file on your computer
- The file should have a .eft extension
- Common locations: Downloads folder, Desktop, or wherever you saved it
- Select the file and click "Open"
- Wait for upload - you should see a progress indicator
- Confirm success - a checkmark or "Uploaded" status should appear
What the Upload Button Looks Like
The upload interface appears as either:
- A "Browse" button with a file selection dialog
- A drag-and-drop area where you can drop your .eft file
- An "Upload Electronic Fingerprints" link that opens a file picker
Step 5: Verify Upload Success
After uploading, verify your fingerprints are attached:
What Success Looks Like
- Green checkmark next to fingerprints field
- "Fingerprints: Attached" or similar status
- Filename displayed (e.g., "john_doe_fingerprints.eft")
- Option to "Remove" or "Replace" the file
What Failure Looks Like
- Red X or error message
- "Invalid file format" error
- "Upload failed" message
- Fingerprints field still shows "Required" or empty
Troubleshooting Common Upload Issues
"Invalid File Format" Error
Cause: You're trying to upload an image (JPEG, PNG) or PDF instead of an EFT file.
Solution: Convert your FD-258 card image to EFT format using SlapEFT. The ATF system only accepts .eft files.
"File Too Large" Error
Cause: Your EFT file exceeds the size limit.
Solution: Re-convert your fingerprints. Properly formatted EFT files are typically under 1MB. If your file is larger, there may be an issue with the conversion.
Upload Stuck or Times Out
Cause: Slow internet connection or ATF server issues.
Solution:
- Check your internet connection
- Try a different browser
- Clear browser cache
- Try during off-peak hours (early morning or late evening)
- Wait and try again later if ATF servers are overloaded
"Cannot Read File" Error
Cause: The EFT file may be corrupted or improperly formatted.
Solution:
- Download a fresh copy of your EFT file
- Re-convert your original FD-258 image
- Don't rename or modify the .eft file
Upload Succeeds But Shows "Pending Validation"
Cause: The ATF system is still processing your fingerprints.
Solution: This is normal. Wait a few minutes and refresh the page. Status should update to "Validated" or "Accepted."
Browser Compatibility Issues
ATF eForms works best with:
- Google Chrome (recommended)
- Mozilla Firefox
- Microsoft Edge
Avoid Internet Explorer and Safari, which sometimes have compatibility issues with the upload functionality.
After Successful Upload
Once your fingerprints are uploaded and validated:
- Complete remaining sections of your application
- Review all information for accuracy
- Submit and pay the tax (or $0 in 2026)
- Print/save confirmation of your submission
- Check status periodically on the eForms dashboard
Multiple Applications? Your EFT file can be reused. You don't need to re-upload or re-convert for future Form 1 or Form 4 applications.
