U.S. Sex Offender Registry Dataset in CSV Format

Nannostomus quotes CSV dataset pricing for your requested coverage and delivery schedule. Tell us whether you need nationwide access or selected states, and whether you want one-time or recurring delivery. We confirm the price and billing period before invoicing.

Yes. You can buy one dataset release for the agreed geographic coverage. A one-time sex offender dataset purchase includes that delivery only; future monthly updates are not included.

Request a real sample to inspect the column names, value formats, and related files before purchase. A state sample reflects the data available for that jurisdiction; it does not establish nationwide field completeness.

Yes. We discuss which states you need and provide sample data for those states. You can review the available fields, format, and fit for your use case before deciding to purchase. Your delivery covers the agreed states.

No. Nationwide describes geographic collection scope, not guaranteed completeness. Collection covers all 50 U.S. states, DC, five territories, and available tribal sources. Record and field availability depend on what each source publishes and what the collection process captures.

Nannostomus compiles sex offender public records from official registries and supplementary public sources. Around 80% of records include a link to the public source profile or registry page, so you can review the published information. Visit our Trust Center for the sources used in each jurisdiction, coverage details, and source limitations.

Yes. The delivery includes CSV files and a separate folder of image files where photos are available from the source. CSV files in photo/ provide photo references; the img/ folder holds the actual images.

The real sample shows column names, value formats, and relationships between files. If your team needs a sex offender data dictionary, ask us to clarify field definitions and empty-value handling before mapping the data into your system.

The 64-character record ID remains stable while the fields used to calculate it stay unchanged. It identifies a registry record, not a nationally resolved person. Deduplication is within states, so the same person can have separate records in different states. The total record count is not a count of unique people.

In the supplied NY sample, downloaddate uses the YYYYMM format and shows the last month the record was collected into Nannostomus’s database. A record refreshed in a later load gets a newer month. Records missing from a later source load are retained with their earlier collection month. This is not the source’s last-modified date or confirmation of current registry status.

An empty field can mean the source did not publish a value, collection or parsing did not capture it, or validation rejected it. A blank value should not be treated as proof that the information does not exist. Confirm the field’s meaning before deciding how to handle missing values in your system.

We notify customers about CSV schema changes by email, usually one month before the change. Use that notice to review field mappings and check whether your import needs to be adjusted.
