Introduction
FBI fingerprint background checks are widely recognized as one of the most reliable methods of identity verification and criminal screening—but just how accurate are they? At PacSigning.com, ensuring your fingerprints are captured correctly is our priority, because we understand even tiny errors could impact an important job, license, or immigration application.
In this blog, we’ll explain the accuracy of FBI fingerprinting, what affects it, and how our certified technicians help guarantee precise, trustworthy results.
How the FBI Fingerprint System Achieves Precision
- Consistent Capture
FBI-compliant submissions—whether via traditional FD-258 cards or Livescan—require strict quality standards to ensure high-resolution ridge detail.
- Digital Encoding
Fingerprints are converted to a standard format (AFIS/eDO) so they can be compared against millions of records consistently and accurately.
- Automated Matching
The FBI’s Integrated Automated Fingerprint Identification System (IAFIS) uses advanced algorithms that deliver a ranked list of possible matches based on ridge similarity.
- Human Verification
Final verification comes from skilled forensic examiners who confirm matches or non-matches, creating extremely high reliability.
This two-tiered system—algorithm + human oversight—makes FBI fingerprint checks highly accurate.
Accuracy Metrics You Should Know
- Automated system matching: ~92–98% accuracy for candidate ranking
- Final examiner review: ~99.9% accuracy in match confirmation
- Overall reliability: Estimated 99.99% in correct identification
These numbers explain why fingerprint background checks remain the gold standard for law enforcement, employment, licensing, and immigration.
Factors That Can Affect Accuracy
| Challenge | How It Impacts Accuracy | PacSigning’s Solution |
| Poor print quality | May produce false negatives or false positives | Livescan preview, retakes, quality control |
| Dry or scarred fingerprints | Ridge details may not register clearly | Technicians prep fingers; use optimal pressure |
| Data entry errors | Mismatched IDs or demographic information | We confirm info before capture |
| Outdated or unlinked records | Missed matches due to system lag | Expert advice & reprints if necessary |
Why PacSigning Prioritizes Clean Prints
- Live quality checks during Livescan sessions
- Fresh ink and cards for traditional roll prints
- Demographic confirmation before submitting data
- No charge reprints if prints are rejected or unclear
- Secure, verified submission to the FBI system
These steps minimize rejection risk and help ensure accurate results for your background check.
Real‑World Misidentification Cases
Although rare, two people with unusually similar ridge patterns may show up as a candidate in automated searches. However, federal examiners will manually rule out false positives, ensuring only genuine matches move forward.
While very uncommon, this is why humans remain critical in the FBI’s process.
Ensuring Accuracy: What You Can Do
- Wash and thoroughly dry your hands before printing
- Avoid applying lotions or hand sanitizers before capture
- Ask for a live quality confirmation during Livescan=
- Confirm your full legal name, birth date, and ORI code before printing
- Request re-prints immediately if saturation or smudging occurs
Proactive steps on your part, along with our quality safeguards, reduce error risk dramatically.
FAQs: Accuracy of FBI Fingerprint Checks
Q: Can fingerprints ever be wrongfully matched?
A: Extremely unlikely. No final match is accepted without expert review, which filters out errors effectively.
Q: Do fingerprints wear out with age?
A: While skin changes can occur, ridge patterns remain unique and legally valid throughout life—especially when captured correctly.
Q: Can scars cause false results?
A: Scars may affect individual ridge clarity but technicians capture surrounding ridges to maintain accuracy.
Q: Are digital scans more reliable than ink prints?
A: Yes—Livescan offers sharper images and fewer resubmissions, improving overall accuracy.
Q: Who oversees mistakes or challenges?
A: Any inconsistencies or disputes can be addressed through a formal Identity History Summary Check (IHS) review with the FBI.
