Introduction
When it comes to FBI background checks, fingerprints are considered the gold standard for identity verification. But just how accurate are FBI fingerprint checks? Short answer: extremely accurate—but not infallible. At PDX Fingerprinting, we rely on high-quality submissions and sound processes to ensure your clearance is based on precise, reliable results.
This post explores how fingerprint checks work, what affects accuracy, and how you can ensure your prints are correctly matched—reducing risk in hiring, licensing, or legal situations.
How the FBI Fingerprint System Works
1. Capture
Whether submitted via ink or Live Scan, fingerprints are submitted in a standardized format (FD-258 paper cards or digital eDO submission) that ensures consistent ridge detail.
2. Encoding
Fingerprints are converted into a standard digital format called Intercepted Fingerprint Image or AFIS format. In Live Scan, this process is immediate.
3. Matching
The FBI’s Integrated Automated Fingerprint Identification System (IAFIS) compares your prints against millions of records and provides a ranked list of potential matches.
4. Review
Human examiners conduct a final verification before confirming any identity matches, making sure ridge formations align.
This two-layer system—algorithmic matching + expert verification—makes the FBI’s fingerprint search highly accurate, with error rates estimated in the low single-digit percent range.
What Can Affect Accuracy
Although FBI fingerprint checks are precise, their accuracy depends on:
Poor Print Quality
Smudged, partial, or unclear prints can lead to false non-matches or false positives.
Aging or Scars
Old injuries can alter ridge patterns, making matches less straightforward.
Similar Fingerprint Patterns
Rarely, two individuals may share highly similar prints; that’s why a human examiner is always involved.
Record Clashes or Updates
If historical prints are outdated or assigned to someone else, it may cause mismatches—usually caught and corrected during the review process.
Accuracy Rates You Should Know
- Automatic algorithm match: ~92–98% accuracy in top candidate lists
- Human examiner confirmation: ~99.9% accuracy
- Overall qualified judgment: Estimated 99.99% reliability in final match or non-match
These numbers demonstrate why fingerprints remain a trusted core method in law enforcement, background checks, and border control.
Why PDX Fingerprinting Prioritizes Accuracy
Our goal is to help ensure your fingerprints are checked accurately the first time. We excel in:
- Live quality preview in Live Scan—allowing immediate re-scan of imperfect prints
- Ink quality control—fresh ink, fresh cards, properly rolled prints
- Data verification—correct demographic info and ORI codes
- Reprint & resubmission—no-cost repeat scans in event of a rejection
These safeguards dramatically reduce the risk of misidentification due to poor quality prints.
When Errors Happen
Though rare, errors can occur. Common scenarios include:
- A fingerprint scan processed too quickly without quality check
- A database oversight if prints were never properly updated
- Miscommunication of ORI codes creating mismatched records
When you work with PDX Fingerprinting, our team tracks any follow-up questions from employers or agencies and collaborates to resolve discrepancies.
How You Can Improve Accuracy
You can help achieve more reliable results by:
- Washing and thoroughly drying your hands before scanning
- Cautioning against lotions or residue that obscure prints
- Asking for a print quality check before leaving
- Confirming demographic data before submission
- Requesting a reprint immediately if any issue is spotted
Proactive clarity can prevent delay and ensure effective results.
FAQ: Accuracy of FBI Fingerprint Checks
Q: Do false positives occur in FBI checks?
A: Extremely rarely. Algorithms return candidates, but only human examiners confirm matches, minimizing false positives.
Q: Can my elderly parent still be accurately fingerprinted?
A: Yes. Age-related changes may slightly affect ridge clarity but don’t block accurate identification when done professionally.
Q: What if I have scars or cuts on my fingertips?
A: Scars can alter prints—but technicians supplement with extra rolls or use Live Scan’s high-resolution to capture surrounding ridges too.
Q: Are digital prints more accurate?
A: Live Scan gives clearer, more consistent images, which helps reduce errors and rejections.
Q: How do I know if my prints were matched correctly?
A: You’ll receive confirmation of match or non-match. If there’s uncertainty, agencies may contact us to repeat the process.
