Delaware DOC Inmate Guide: Visiting, Mail, Money & Phone Calls
The Delaware Department of Correction (DOC) operates the state's prisons and community-supervision programs across Delaware. For families, the department's rules are what decide how you find a loved one, visit, write, call, and send money — and Delaware has some of the most specific mail rules of any state, along with recently expanded visiting. This guide brings the essentials together so you can stay connected without learning every rule the hard way.
About the Delaware prison system
Delaware runs a combined jail-and-prison system, meaning the state department handles both pretrial detention and sentenced incarceration across a small number of facilities, including the large James T. Vaughn Correctional Center. The Dover headquarters is an administrative office where policy questions go, while mail and money are handled through the specific facility and the department's providers. Every incarcerated person is assigned an SBI number that identifies them throughout the system and is required for visits, mail, and deposits.
Because people are moved between facilities and between pretrial and sentenced status, confirming exactly where your person is held before acting is the habit that saves the most frustration. If you are not sure which facility holds them, our guide on how to find someone in jail or prison explains how to trace an incarcerated person through official records, and you can search their name directly on AllRecentArrests.us to see their facility and status.
Visitation process and timings
Delaware has expanded in-person visitation to allow two adults and two children per inmate visit, and a valid photo identification is required for every visitor. The rules on the visit itself are strict: no property may be exchanged between an inmate and their visitors, and all cards, letters, and similar items must be sent through the mail rather than handed over in person. Visitors may, however, bring money to deposit on an inmate's account at a lobby kiosk, or purchase a debit card to use approved vending machines during the visit.
Because the rules are specific and dress codes apply, it pays to prepare before your first trip. Our complete prison visitation guide covers getting approved, dress codes, and what to expect at the checkpoint. Each facility sets its own visiting schedule, so confirm the current days and times for the institution holding your person, and arrive early enough to clear screening.
Mail: Delaware's specific rules
Delaware has unusually detailed mail requirements, and letters that do not follow them are rejected. Incoming mail, except legal mail, must be sent in a white envelope no larger than 4 by 9½ inches, on paper no larger than standard letter size, and must include a return address, the inmate's name, and their SBI number or date of birth. Greeting cards must be commercially produced on standard card stock — battery-operated, embellished (rhinestones, stickers, glued-on items), non-standard, or multi-fold cards are not allowed — and any use of crayon, highlighter, or marker, or any glitter, lipstick marks, stains, perfumes, oils, or unknown substances, will get a letter rejected.
Because the details matter so much here, it is worth double-checking every envelope before you send it. Our breakdown of how to send mail to an inmate covers the address format and the kinds of things that most often get mail returned, which apply doubly in Delaware. Legal mail is handled separately and more protectively, so mark it clearly and keep it distinct from personal correspondence.
How to send money and make phone calls
Delaware gives families a few ways to fund an inmate's account: you can add money at kiosks located in the gatehouse or main entrance of each facility, go online through ViaPath/GTL, or mail a money order directly to ViaPath/GTL using the required form, always with the inmate's name and SBI number. During a visit you can also use the lobby kiosk. Our overview of how to send money to an inmate compares the deposit methods and posting times, and our ViaPath provider guide covers the connected accounts, since Delaware uses ViaPath for both money and phones.
Phone service lets the incarcerated person place calls to numbers on their approved list, so the practical first step is to set up and fund a prepaid account tied to your number. Under the FCC rate caps that took effect in 2026, per-minute rates have dropped sharply, and our guide to calling an inmate explains account setup and cost control. Because you cannot mail packages directly, our explainer on how prison commissary works shows what a funded account buys inside.
Legal mail, emergencies, and avoiding scams
Legal or privileged mail from an attorney or a court is handled separately from ordinary correspondence and is generally opened only in the incarcerated person's presence, so keep legal documents out of personal letters and mark them properly. For emergencies such as a death, serious illness, or birth in the family, the reliable route is to call the facility and ask how to get an urgent message to the person or their case manager, rather than trying to reach them directly, and keeping the SBI number handy makes that call go faster.
Be cautious, too, about where you get information and send money. The Delaware DOC inmate search and the department's named deposit vendors are the authoritative channels, so paying an unfamiliar third-party site to "locate" a person or forward a deposit is a common way families lose money for something the state provides directly. If you are worried about a loved one's medical care, mental health, or safety, contact the institution's staff directly, explain the situation clearly, and keep a record of who you spoke with and when, since a simple log makes follow-up far easier if the issue is not resolved the first time.
The white-envelope rule in practice
Delaware's specific mail requirements make the state stand out among corrections systems, and a moment spent following them exactly saves your letter from being rejected. Use only plain white envelopes no larger than 4 by 9½ inches, plain letter-size paper, dark ink, and a return address alongside the inmate's name and SBI number. If you want to send a card, buy a commercial one on standard card stock — no music, batteries, glitter, foil, rhinestones, stickers, or multi-panel folds — because anything embellished will come back to you. It is worth keeping a small stash of the right envelopes on hand so you never have to improvise.
Because those rules apply to every piece of personal mail you send, the effort to get them right the first time pays off across a whole sentence. Legal mail follows different, more protective rules, so keep it in its own envelope and mark it clearly rather than mixing it with personal correspondence.
Making the most of an expanded visit
Delaware's expansion of in-person visits to two adults and two children per inmate visit is meaningful for families with kids, since it lets more of the household connect at once. Bring a photo ID for every adult, plan around the no-property-exchange rule (nothing is handed over the table), and remember that letters and cards go through the mail rather than the visiting room. If you want to add money on a visit, use the lobby kiosk, and if you plan to use vending machines during the visit, the debit-card option available at the lobby is how you access approved items.
Keeping records and getting help
Keeping your own records — the SBI number, current facility, deposit receipts, and any court dates — smooths every step, because a missing or wrong SBI number is behind most of the delays families run into. If you are supporting a household through an incarceration, our overview of financial help for families of incarcerated people lists benefits and nonprofits that may ease the strain. When guidance you read online conflicts with what the facility says, the facility is always the authority to follow.
Staying consistent through the sentence
Whatever mix of visits, letters, and calls you settle into, consistency matters more than any single grand gesture, and a predictable rhythm gives someone inside something reliable to count on through a hard stretch. As a release date approaches, preparation pays off — lining up identification, housing, and income before the day arrives makes the first weeks home far less chaotic. Our reentry guide for life after prison covers those first steps, and many returning citizens qualify for help through SNAP, Medicaid, and TANF soon after release.
Why Delaware has no county jails
Delaware provides a unified correctional system, with all correctional facilities and institutions falling under the jurisdiction of the State. There is no county jail in Delaware — the same department holds people awaiting trial and people serving sentences. If you have been told to contact "the county jail", that is the wrong agency here.
The services provided here are pretrial detention, sentenced custody and probation and community supervision. That is a clinical remit rather than a custodial one — people are here because of a medical or behavioural health need, not because this is where they are held.
What records still exist for the Delaware Department of Correction
Closing a prison does not erase its statistical record. The department continues to publish pre-closure reports for this institution, including departmental annual reports covering the Bureau of Prisons and community supervision and bureau and division profiles setting out which office is responsible for what.
These are worth knowing about if you are reconstructing a timeline — confirming when someone was held here, what the conditions and population were at the time, or supporting a claim that depends on how the institution was operating. They are statistical rather than individual, so they will not contain a named person's file; for that you need a records request to the department rather than a published report.
Why Delaware has no jail statistics to look up
If you go looking for federal jail statistics on Delaware, you will not find any. The Bureau of Justice Statistics Census of Jails for 2019 counted jails in 46 states — and Delaware is not among them. That is not a gap in the data. It is a direct consequence of the unified system: a jail census counts locally-run jails, and Delaware has none to count.
The practical effect is that the comparisons available in other states — this county jail against that one, rated capacity against peak population — simply do not apply here. There is one operator, and its own reporting is the only source. When you see a directory listing a "county jail" in Delaware, it is almost always mislabelling a state facility.
It also means the agency itself is the single point of contact for everything: locating someone, visiting, mail, deposits and complaints all run through the same department rather than being split between a sheriff and a state corrections office.
Who runs the Delaware Department of Correction
The department supervises between 4,500 and 5,000 people in its correctional facilities and roughly 13,000 probationers in the community. That total is the context for everything else here — a system of that size sets policy centrally and applies it uniformly, which is why the answer you get rarely changes depending on who you ask.
What this department operates
The department lists 4 adult institutions. This record is the department itself rather than any one prison, so it has no beds, no visiting room and no warden of its own — which is why the practical details you need always belong to a specific institution, not to headquarters.
"Level V" is Delaware's term for full incarceration; the state runs a graded system where lower levels mean work release, home confinement or probation. If paperwork refers to a Level V sentence, that means prison. With only four secure institutions statewide and one women's prison, placement options are narrow and transfers between them are common.
Delaware's four Level V secure prisons are the James T. Vaughn Correctional Center in Smyrna, Sussex Correctional Institution in Georgetown, the Delores J. Baylor Women's Correctional Institution in New Castle and the Howard R. Young Correctional Institution in Wilmington. Knowing the list is more useful than it looks: a transfer is announced by institution name, often with no explanation of where that is or how far you will now have to travel.
That distinction matters when you are chasing an answer. Department policy sets the framework — visiting eligibility, approved vendors, grievance procedure — but the schedule, the phone number, and the person who can actually help are all at the institution holding your family member. Start by confirming which prison that is, then work with that facility directly.
How to find someone in this department's custody
The department's official search tool is the department's "Locate an Offender" search, at doc.delaware.gov. The same site carries the department's official pages for sending money to someone in custody and for mail instructions. Read both before sending anything: a unified system means one set of statewide rules rather than per-county variation, so getting it right once means getting it right for every Delaware facility.
Your first steps
If someone you love has just entered the Delaware system, focus first on the essentials: confirm which facility holds them and write down their SBI number, get approved to visit and note the two-adults-and-two-children rule, and set up a deposit through a kiosk, ViaPath online, or a mailed money order so calls and commissary are possible. Pay close attention to Delaware's white-envelope mail rules, since letters that do not follow them are returned. When a policy you read online conflicts with what the facility says, trust the facility, and confirm anything important directly before you rely on it.
A well-organized Delaware family — SBI number written down, envelopes stocked, deposit routine set — runs into far fewer problems than one improvising each week, and that groundwork pays off across every stage of a sentence and the transition home. When guidance you read online conflicts with what the Delaware DOC or a specific facility tells you directly, treat the department as the authority to follow.
