Colorado sex offender registry: how Colorado’s registry works for a Castle Rock search. Three things that make a Castle Rock search accurate.
Castle Rock sex offender search by address: search near an address in Castle Rock. Start from the street you care about.
The question most people bring to a Castle Rock page is about one street — a home you are renting, a school, a park, a babysitter’s house. Enter that address or its ZIP code and pick a radius: a few blocks for a single home, a mile or more for a neighborhood. Results are the full registry records nearest that point, with photographs, offenses and the link to the official record.
Radius search sees registrants whose published address we have placed on a map coordinate, so when you are checking a particular person, search their name as well. To keep watching an area rather than checking once, set up a location alert and you will be emailed when someone registered nearby is added or moves in.

Colorado sex offender record: what a Colorado registry record shows — and what it doesn’t. Read the record, not just the name.
A registry record typically carries the registrant’s name and any aliases, a photograph, the address they last reported, the offense or offenses that required registration, and their registration status. Most also give a physical description, and many give a risk level or tier.
What it is not: a full criminal history. A registry lists the offenses that carry a registration duty, not every arrest or conviction, and an address is where someone last reported living, not proof of where they are today. Offenses that never required registration will not appear here at all — that is what a criminal records search is for.
Search sex offenders in Castle Rock two ways. Two ways to use it: look up a person, or check around an address.

Castle Rock offender search FAQ. Quick answers before you search.
Are there sex offenders near me in Castle Rock?
Yes — we index about 73 registrants with a Castle Rock address, about 10 per 10,000 residents. Whether any live near you depends on the street, not the city average, so search from your own address or ZIP and widen the radius until it covers the area you care about.
How many sex offenders are in Castle Rock, CO?
We index approximately 73 registrants with a Castle Rock address — about 1 in 1,002 residents. Treat the figure as scale rather than a fixed number: the registered population moves continuously as people are added, move, or are released from the requirement. When you need an answer about a specific person, run a search.
How do I find sex offenders in Castle Rock by address?
Enter a Castle Rock street address or ZIP code and create a free account to see how many registered sex offenders live near it. To see who they are — names, photographs, offenses and exact addresses — it is $5 once, or $5 a month with an email when someone moves in or out. Checking one person? Search by name; your first 25 searches are free.
Is there a Douglas County sex offender list?
Registries are kept by the state, not the county, so there is no separate official county list. The Douglas County page lists the registrants we index across the county (about 248), with a per-city breakdown, and a search can be narrowed to any Douglas County city or ZIP.
How do I check a specific person in Castle Rock?
Type their last name and add whatever else you hold — first name, date of birth, or narrow to Castle Rock by city or ZIP. You get scored matches with photographs and official record links. Your first 25 searches are free, no card required.
Does a Castle Rock search include people registered in other states?
Yes — that is the point of searching here rather than one state's site. A search runs across every US registry at once, so someone now in Castle Rock who was registered elsewhere still surfaces. Narrowing to Castle Rock filters where people live; it never shrinks where we look.
Which cities near Castle Rock have their own sex offender page?
Nearby, we publish pages for Parker (about 10 miles away), Centennial (about 17 miles), Aurora (about 22 miles), Lakewood (about 27 miles) and Denver (about 28 miles), each with its own count. Distances are straight lines between the cities. To cover the area around one address instead, search outward from it and widen the radius past the city line.
Can I get an alert when a registered sex offender moves to Castle Rock?
Yes. A location monitor watches an address and radius in Castle Rock and emails you when someone registered nearby is added or moves in, so you are not re-running the same search every few weeks.
Is this the official registry list?
No single official "list of sex offenders in Castle Rock" exists — registries are maintained per jurisdiction, not per city. What you search here is our continuously updated national dataset, each record carrying a link to its official registry entry so you can verify any result at the source that published it.
Standard results are not a consumer report; FCRA-covered decisions run through FCRA Partner Access, our separately enabled regulated service.
