New Castle Delaware Sex Offender Registry
This page covers sex offenders in the city of New Castle, Delaware. New Castle is a small city within New Castle County, not the county itself. Those are two different things. You can search for registered sex offenders in New Castle city using the Delaware State Police sex offender registry. The city of New Castle has 157 registered sex offenders, one of the highest counts in the state relative to its population. This page explains how to search the registry, how registration works for New Castle city residents, what the tier system means locally, and where local law enforcement links to these resources.
New Castle City Sex Offender Registry at a Glance
Search New Castle Sex Offenders Online
The best place to start is the Delaware Sex Offender Central Registry, which is the state's official public database. The Delaware State Police maintain it and update it nightly. You can search by name or by street address and set a radius. That radius search is useful if you want to see all registered offenders near a specific address in New Castle city. Results show name, photo, current address, offense history, and tier level. The search is free. No login is needed.
Only Tier II and Tier III offenders appear in public results. Tier I, which is the low-risk category, is restricted to law enforcement only. So if you run a name search and get no result, it could mean the person is a Tier I registrant or not on the registry at all. The registry does not tell you which. The map view on the registry site works well for checking specific blocks or ZIP codes in New Castle. ZIP code 19720 covers most of the city. You can also sign up for email alerts through the registry site. Those alerts notify you when a new offender registers or when an existing registrant moves into a New Castle ZIP code.
For broader checks outside Delaware, the National Sex Offender Public Website pulls data from all 50 states. Delaware participates. Use it to check whether someone has a conviction from another state before they moved to New Castle.
Note: Registry data is updated nightly, but offenders have 3 days to report a move. There can be a short gap between when an offender moves and when the database reflects it.
New Castle City Police Department Resources
The New Castle City Police Department maintains a public page of important links at newcastlecitypolice.com/important-links. That page gives residents direct access to the Delaware Sex Offender Registry and other public safety resources. It is a practical starting point if you are not sure where to search. The department does not handle sex offender registration directly, but it does coordinate with the Delaware State Police on monitoring and compliance checks within the city.
The New Castle City Police Department works alongside DSP Troop 2, which is the State Police unit responsible for sex offender registration in New Castle County. When DSP identifies a registrant who may be out of compliance in New Castle city, local police can be part of the follow-up. The city department also responds to calls involving registered offenders and has the same authority to check compliance that other law enforcement agencies in the county do.
The important links page at the New Castle City Police site points directly to the sex offender registry and other public safety databases. Bookmark it as a quick way to get back to the registry search.
Sex Offender Registration for New Castle City Residents
People who live in the city of New Castle and are required to register as sex offenders must do so through the Delaware State Police, not through the New Castle City Police. The registration site for all of New Castle County, including the city, is Delaware State Police Troop 2, located at 100 Corporal Stephen J Ballard Way in Newark, Delaware. That is a different city, but it is the designated registration point for everyone in New Castle County, including city of New Castle residents.
The Troop 2 registration office is open Tuesday through Friday, 8:30 a.m. to 3:15 p.m., with a lunch break from 11:45 a.m. to 12:30 p.m. No service is available on Mondays. That is important to plan around. If your verification date falls on a Monday, you need to come in before or after the weekend window. Missing a verification deadline is not a minor issue. Failure to register or verify on time is a Class G felony under Delaware law.
The 3-day rule applies here. Any person required to register must do so within 3 business days of conviction. Any change of address, including a move within New Castle city, must be reported within 3 days. Someone moving to New Castle from another state must register in Delaware within 3 business days of establishing residency. That applies even if they were already registered in their former state. If you are visiting Delaware for 7 or more consecutive days, or for 30 or more cumulative days in a year, you must also register within 3 days of arrival. For questions, call the DSP S.O.A.R. unit at (302) 739-5882 or (302) 672-5306.
Note: Registration must be done in person at DSP Troop 2 in Newark. New Castle City Police do not accept registrations and cannot process your paperwork on behalf of the State Bureau of Identification.

According to data from City-Data, the city of New Castle had 157 registered sex offenders as of April 2026. That count puts New Castle among the cities with the highest concentrations of registered offenders in Delaware relative to its population.

That does not mean the city is uniquely dangerous, but it does mean the local registry data is dense and worth checking if you live here or are moving here.
The City-Data page for New Castle provides a breakdown of registered sex offenders in the city by tier, address, and offense type. It is a useful supplement to the official state registry search.
On top of the 157 registered offenders with fixed addresses, New Castle city also has a notable number of homeless registrants. Research published by the National Library of Medicine found that ZIP code 19720, which covers much of New Castle city, had 10 homeless registered sex offenders. That was 8.3% of the statewide total of homeless registrants at the time of the study. New Castle County overall had 61 homeless registrants, the highest of any county in Delaware and 50.8% of the statewide homeless total.
Homeless registrants in Delaware face stricter verification schedules. Tier III homeless offenders must verify every 7 days. Tier II homeless offenders verify every 30 days.

The DSP S.O.A.R. unit monitors compliance and posts public notices when a homeless registrant falls out of compliance in a given area.

Sex Offender Tier Notifications in New Castle
Every registered sex offender in New Castle city is classified under one of three tiers. The tier is set by the sentencing court or the Delaware Department of Justice. It is based on the offense type and the level of risk the person is assessed to pose. Tier assignment determines how long the person stays on the registry, how often they must verify, and what kind of community notification takes place near their address in New Castle.
Tier I offenders are low risk. They register for 15 years, verify once a year, and do not appear in public searches. Their data is shared with law enforcement only. New Castle residents conducting registry searches will not see Tier I names. Tier II offenders are moderate risk. They register for 25 years, verify every 6 months, and appear in public search results. If a Tier II offender lives, works, or goes to school near a New Castle school or daycare center, that institution receives a notification. Tier III offenders are high risk and must register for life. They verify every 90 days, appear in public results, and the state issues direct community notifications to neighbors in New Castle when they register at a local address.
Under Title 11, Section 4120 of the Delaware Code, the full legal framework for these tiers and their requirements is set out in statute. The law was updated in 2023 through Senate Bill 66, which changed how schools share registry information with parents. Schools no longer keep physical binders of sex offender notices. Instead, they must inform parents and staff of the registry website and allow them to sign up for email alerts. Schools with websites must post the registry URL. Schools without one must send that information out in writing each year.
If you get a Tier III community notification about a New Castle sex offender moving to your street, read it for factual information. Report any violations or suspicious behavior to the DSP S.O.A.R. unit at (302) 739-5882. Do not harass or threaten registered offenders. Delaware law protects registered offenders from harassment, and violations can result in criminal charges.
Note: Tier II offenders in New Castle who have completed 10 years on the registry and whose offense did not involve a minor may petition Superior Court to be reclassified as Tier I, which would remove them from the public search.
