National, Federal, and County Records: What Gets Checked and Why

Three different criminal searches, three different things they catch, and why you need all of them.

Families are sometimes surprised to learn that a proper criminal background check is not one search but several, conducted at different levels of the court system. The reason is simple: no single search sees everything, and the gaps between them are exactly where a cursory check fails. Understanding the three main layers shows why a thorough screening insists on all of them.

A national criminal search is the broad first pass. It draws on a large, multi-jurisdictional database compiled from many sources, court records, incarceration and inmate records, probation and parole data, arrest records, and includes sex-offender registry screening across all states and global watchlist checks. It also typically incorporates an identity trace that surfaces a candidate's prior names, aliases, and addresses, which then guide where else to look. Its strength is breadth; its limit is that databases are not exhaustive and can lag or miss records, which is why it is a starting point rather than the whole story.

A federal criminal search covers an entirely separate court system, the country's federal district courts, and this is its importance: serious federal offenses do not appear in county records or in most national database searches. Fraud, embezzlement, identity theft, certain crimes against children, and similar matters are prosecuted federally and would be invisible to a check that skipped this layer. Federal records can be difficult to match to a person because of limited identifying detail, so this search rewards experienced investigators who confirm identity carefully.

County criminal searches go to the source. Court records ultimately live at the county level, and a county search examines them directly, felonies and misdemeanors alike, in each county where the candidate has actually lived, often guided by the address history the national search uncovered. Because it inspects the original records rather than a database summary, a county search is the most authoritative layer for the places a person has spent time, and it confirms and completes what the broader searches suggest.

Used together, the three cover one another's blind spots: national for breadth, federal for the serious cases county and database searches miss, and county for authoritative depth where the person has lived. A screening that runs only one of them is not thorough, whatever it is called. The point of layering is not redundancy; it is making sure there is nowhere a relevant record can hide. That conviction is the heart of how Nannies + more…® works.
