It’s a collection of U.S. sex offender registry data about individuals who are legally required to register as such. The data comes from public sources and usually includes personal details, addresses, conviction history, and photos.
Most states run their own registry websites, and the quality varies a lot. Some publish complete data, while others don’t update regularly. If you need a single source covering all 50 states, updated every month and already cleaned and normalized, Nannostomus provides a much easier way to work with this information.
Yes. Each state has its own official sources — sometimes one website, sometimes several. We collect the data for every state from its state-specific sources, process it, and merge it into a single CSV file. You don’t have to deal with inconsistent formats or missing fields since everything comes in one clean, unified dataset.
We include transparency reports with every update. You can compare record counts and spot changes month-over-month. This lets you check your copy of the U.S. sexual predator database against the state and national registries at any time.
Right now we dedupe within each state, so one person won’t appear twice in the same registry. We’re also working on full cross-state entity resolution. Once it’s ready, the same person appearing in several states will be merged into a single unified profile.
We follow the official registries. If a state removes or updates a record, that change appears in the next monthly update of the all-states sex offender dataset. We don’t apply our own logic for deceased or relocated offenders.
We deliver the data directly to your storage. Most clients use Amazon S3, but we can also send it to Google Cloud Storage, Azure Blob, FTP/SFTP, or a shared bucket you provide. If needed, we can also make the data available via direct download or through our API.
Load the sample data first, then request pricing for the state coverage your team needs.
