Before you offer on a home in Colorado, run its address through the official registry: the Colorado Sex Offender Registry, run by Colorado Bureau of Investigation (CBI). It is free, it takes two minutes, and it is the check listing sites never do for you.
Run the check
Check the records behind the address before you offer.
Check any address — free preview1. Open the official Colorado registry. 2. Search by the home's street address (a radius or map search works best). 3. Note the counts within a quarter mile, a half mile, and a mile — distance bands tell you more than a single pin. 4. Repeat the search the week you close. Registries update as people move and register new addresses.
Can you get an exact count in Colorado?
Partly — Colorado's official search can produce a count, but only through the route below (a subset, a radius detour, a CAPTCHA or a display cap), so getting the number takes an extra step.
How it works: CBI search by name/city/ZIP returns countable lists, but Colorado posts only registrants meeting its website criteria (e.g. felony convictions, multiple convictions, SVPs) — not every registrant — so counts are subset counts.
Worth knowing: NSOPW URL redirects to apps.colorado.gov/apps/dps/sor/ (200, 'CBI: Sex Offender Registry').

How to read what comes back
Treat the addresses as reported addresses: the system depends on registrants reporting moves and on agencies processing them, so the map is a strong signal, not a guarantee. Judge the pattern around the address — how many, how close, typical for the area or an outlier — and remember the registry lists only people required to register; it is not a crime map.

A CurbFacts report summarizes the same public registry data as ZIP-level counts for the address — never offender names or photos. The full Colorado records guide and the Colorado disclosure guide cover the rest of the record file.
Frequently asked questions
Can I get an exact registrant count for a Colorado address?
Partly. CBI search by name/city/ZIP returns countable lists, but Colorado posts only registrants meeting its website criteria (e.g. felony convictions, multiple convictions, SVPs) — not every registrant — so counts are subset counts.
Who runs the Colorado registry?
The Colorado Bureau of Investigation (CBI) — the official search is the Colorado Sex Offender Registry. It is free; if a site asks you to pay for registry results, you are on a data broker.
Does a CurbFacts report show offender names or photos?
No. Reports show the count of registrants in the home's ZIP from state registry data, and link you to the official registry if you want the underlying public record.
