How Massachusetts’s registry works for a Cambridge search
Massachusetts's registry publishes a birth year rather than a full date, so two people with the same name born the same year can look alike. Confirm a match with the photograph and the offense details before relying on it.
Massachusetts’s own public search is Massachusetts SORB. It answers for Massachusetts only. People move across state lines, and a check limited to Massachusetts misses a registration made anywhere else. A Cambridge search here reaches Massachusetts, its neighbours (Connecticut, New Hampshire, New York, Rhode Island) and every other US registry in the same pass — so a registration from a prior state still surfaces on someone who now lives in Cambridge.
Read the record, not just the name. Names repeat, so confirm the photograph, the date of birth or age, and the offense detail, then follow the official record link to verify at the source.
Search near an address in Cambridge
The question most people bring to a Cambridge 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.

What a Massachusetts registry record shows — and what it doesn’t
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. How to read a record · Criminal record search

Cambridge offender search FAQ
Are there sex offenders near me in Cambridge?
Yes — we index about 42 registrants with a Cambridge address, about 3.5 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 Cambridge, MA?
We index approximately 42 registrants with a Cambridge address — about 1 in 2,819 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 Cambridge by address?
Enter a Cambridge street address or ZIP code and choose a radius — from one mile up to a whole area. Each result is the full registry record: photograph, offenses and the link to the official record. Radius search sees registrants whose published address we have placed on a map coordinate, so pair it with a name search when you are checking a specific person.
Is there a Middlesex County sex offender list?
Registries are kept by the state, not the county, so there is no separate official county list. The Middlesex County page lists the registrants we index across the county (about 547), with a per-city breakdown, and a search can be narrowed to any Middlesex County city or ZIP.
How do I check a specific person in Cambridge?
Type their last name and add whatever else you hold — first name, date of birth, or narrow to Cambridge 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 Cambridge 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 Cambridge who was registered elsewhere still surfaces. Narrowing to Cambridge filters where people live; it never shrinks where we look.
Can I get an alert when a registered sex offender moves to Cambridge?
Yes. A location monitor watches an address and radius in Cambridge 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 Cambridge" 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.
