National Criminal Databases: What Employers Need to Know

National criminal databases are large aggregated collections of criminal-record information gathered from many public and commercial sources. Depending on the database provider, those sources may include court repositories, departments of corrections, state agencies, sex-offender registries, and other public-record sources.

The search is generally performed using identifiers such as name and date of birth. The purpose is to identify possible records that may warrant additional research.

Think of it like throwing a large fishing net into the ocean. The net may catch something you would not have known was there. But you still have to identify and verify what you caught.

There is no single commercial criminal database that guarantees complete, current coverage of every county, state, and federal criminal record in the country. Coverage depends on what records are available to the data aggregator, how often each source is updated, what identifiers are included, and whether a jurisdiction makes its information available at all.

Federal criminal records are also maintained separately from most state and county court systems. An employer should not assume that a national criminal database search is the same thing as a federal district court search.

That means a clear database result does not necessarily mean the person has no criminal history. It means the database did not return a potential matching record based on the sources and identifiers available to it.

This is where the database earns its place in a comprehensive screening program: it can identify criminal activity outside the jurisdictions revealed by residence history.

Imagine an applicant who has lived and worked in Missouri their entire adult life but was arrested or convicted while visiting Clark County, Nevada. An address-history search may never point a screening provider toward Nevada. A broad criminal database may surface that possible record and give the consumer reporting agency a reason to investigate the authoritative source.

That is the value of the tool. It broadens discovery. It should complement jurisdiction-based research, not replace it.

Database records can be incomplete, stale, duplicated, or missing final case information. A possible match may not contain enough identifying information to determine whether the record belongs to the consumer being screened. A case may also have changed after the database last received an update.

For consumer reporting agencies, accuracy obligations matter. The FCRA requires CRAs to follow reasonable procedures to assure maximum possible accuracy. When public-record information is reported for employment purposes, additional FCRA requirements can apply, including requirements designed to keep reported information complete and up to date.

That is why a possible database record should be treated as a lead that needs appropriate source-level research before it becomes part of an employment consumer report. The CRA should confirm that the record belongs to the consumer, determine the current disposition, evaluate whether it is reportable, and ensure the information being provided is accurate and current.

At 3rd Degree Screening, I think of the national criminal database as an early discovery layer in the screening process, alongside identity and trace information.

First, establish identity and develop names. Confirm who is being screened and identify names or aliases that may be relevant to the search.

Second, develop jurisdiction history. Use appropriate trace information to identify counties, states, and other jurisdictions associated with the consumer.

Third, run broad database discovery. Use the national criminal database to identify possible records, including activity outside known residence history.

Fourth, search authoritative sources. Conduct the appropriate county, statewide, federal, registry, or other source searches based on the screening package, jurisdictions, role, and applicable law.

Fifth, verify possible records before reporting. Confirm identity, disposition, accuracy, currency, and legal reportability before information is included in the consumer report.

We sometimes speak with employers who chose a low-cost database-only product because they believed they were receiving a complete nationwide criminal search. The problem usually becomes visible only after the organization learns about a criminal record that did not appear in the original screening report.

That creates an uncomfortable question: why was the record missed? If the answer is that the employer purchased a pointer-data search and treated it as a complete criminal background check, the issue is not that the database failed to do something it was designed to do. The problem is that the product was expected to provide coverage it could not guarantee.

Some organizations may intentionally choose a lower-cost, limited screening package. That is a business decision. But they should make that decision with a clear understanding of the tradeoffs rather than assuming the word national means complete.

Is the national criminal database the entire criminal search, or is it supplemental to county, state, federal, and other source searches? What types of sources feed the database, and how current is the underlying information? When a possible record is returned, do you verify it at the authoritative source before reporting it?

How do you develop names, aliases, and jurisdictions to determine where source searches should be performed? Are federal criminal searches conducted separately from county and state searches? How do you determine whether a record is accurate, current, and legally reportable? What happens when database information conflicts with the source record?

National criminal databases are valuable. They are fast, broad, and capable of identifying possible criminal activity that jurisdiction-based searches alone might not reveal. That is exactly why they belong in a well-designed screening program.

But the database should be understood for what it is: a discovery and pointer tool, not a guarantee that every criminal record in America has been searched.

It is not about one search. It is about how the entire screening process works together.
