How to search for sex offenders in Guam
Two ways to check the Guam sex offender registry: manually on the official state site, or programmatically across Guam and every other US registry with a single API call.
Option 1 — Search the official Guam registry
- Open the official Guam sex offender registry public search.
- Search by last name (required), first name, or by city / ZIP / address.
- Open a result to see offenses, registration status, and known addresses.
- Note the record URL — it’s the authoritative source for that person.
The public Guam site is best for a one-off, manual lookup. It won’t scale to bulk screening or cover other states in one search.
Option 2 — Search Guam with the Offendersearch API
One authenticated request queries the Guam registry plus the national NSOPW source, de-duplicates people across sources, scores each match, and returns provenance and freshness on every record.
POST /v1/search
{
"query": { "lastName": "Doe", "state": "GU" },
"jurisdictions": ["GU", "NSOPW"],
"locationScoped": true,
"freshness": "standard"
}This is a live demo of the API shape returning sample data. Real, scored results across every registry require a free account with billing enabled.
