Inmate Locator

Finding a State Inmate at TDCJ - Rufus H. Duncan Geriatric Facility (N6)

If you're trying to locate someone in Texas state custody at TDCJ - Rufus H. Duncan Geriatric Facility (N6) in Diboll, the Texas Department of Corrections maintains a state-level inmate locator that covers all DOC facilities. Every state runs its own system, so the search experience differs significantly from federal or county-level locators. If the DOC locator does not return the person you're looking for, call TDCJ - Rufus H. Duncan Geriatric Facility (N6) directly at 936-829-2616 to confirm current custody status.

Using the State DOC Inmate Locator

The Texas DOC inmate locator searches by full name, DOC inmate number, or both. The state inmate number is assigned at intake and stays with the inmate across transfers between facilities within the state, but it does not transfer if the inmate moves to another state or to federal custody. State locators typically return the inmate's current housing facility, custody level, projected release date, and parole eligibility, though specific data fields vary by state.

When the Inmate Doesn't Appear in the DOC Locator

A state inmate may be missing from the DOC locator for several reasons. Newly sentenced inmates often spend weeks at a county jail awaiting transfer to the state reception center, during which they are not yet in the DOC system. Inmates in transit between facilities may be temporarily missing. Some states delay public records by 24 to 72 hours after intake. The InmateAid inmate search can help locate someone during this gap period because it pulls from county jail rosters as well as state systems.

State Inmate Numbers and Out-of-State Transfers

If the inmate was recently transferred from another state under an interstate compact, or moved to federal custody on writ, the Texas DOC locator may show them as "in transit" or remove the record entirely. To track inmates across state or federal jurisdictional moves, call 936-829-2616 for current location and case status.

Once You've Located the Inmate

When you confirm the person is at TDCJ - Rufus H. Duncan Geriatric Facility (N6), set up an inmate phone account with the facility's contracted provider and arrange any money transfer or commissary funding needed. For phone discount plans, money transfer, and mail services that work with Texas state facilities, see InmateAid's inmate services and call 936-829-2616.

How to Save Money on Inmate Calls

Understanding Prison Phone Services: How to Save on Inmate Calls

Prison phone companies hold a monopoly within the facilities they are contracted with, resulting in shared profits and minimal incentives for representatives to promote cost-saving measures to customers. These companies typically display their rates, often offering multiple pricing tiers. However, the primary factor determining call costs is the type of phone number used and the location of both the caller and the inmate.

In federal prisons, acquiring a new local number can significantly reduce call rates, lowering costs from $0.21 to only $0.06 per minute. The Federal Bureau of Prisons provides inmates with 300 minutes per month, and local line services like InmateAid cost $5.00 per line, without any hidden fees or bundled services.

For non-federal facilities (county jail, state prison, private and ICE detention centers), the benefits of using a local number have diminished, making market intelligence crucial. InmateAid specializes in identifying the best deals in various scenarios. While approximately 30% of the time no savings can be achieved—a reality acknowledged by other providers—InmateAid guarantees a refund if they cannot save you money.

For more detailed information on inmate calls, individuals are encouraged to visit the InmateAid website and navigate to the facility where their inmate is incarcerated. By accessing the Prison Directory and following the links to the Discount Telephone Service, individuals can obtain an honest estimate before making any purchases.

How to Send Money to an Inmate

How to Send an Inmate Money in Texas

These are general guidelines for sending money to an inmate's commissary account. Inmates need money to access several privileges like weekly shopping at the commissary, making phone calls, using the email service where offered, using the electronic tablets where offered and paying their co-pay when needing the medical or dental services.

What is a Commissary?

A commissary is a store within the correctional institution. Commissary day is usually held once a week and can only be enjoyed if the inmate has funds in their commissary account. An inmate's commissary account is like a bank account within the prison. If the inmate has a job, their paycheck is deposited into this account, too.

The Commissary sells various products that the inmates may purchase if they have money on their books. The commissary sells clothing, shoes, snacks and food, as well as hygienic products like soap, shampoo, and shavers. The commissary might also sell entertainment-related products like books, magazines, televisions, radios, playing cards, headphones, MP3 players, electronic tablets like an iPads (no internet access), songs, and educational programming.

How do you send money to an inmate?

Sending money to an inmate varies from state to state, depending if it is county, state, or federal, their ways of accepting money for inmates change by the money transfer company they’ve contracted with.

Federal Prisons and some state-level prisons have centralized banking systems which means that you do not need to know where they are specifically, just that they are in the state systems of for instance the California, Texas, Florida DOC, or the FBOP to name a few.

Some facilities will allow you to deposit cash through the lobby window stand-alone kiosk in the lobby or visitation room. Most facilities will also accept a postal money order mailed to the institution’s inmate mailing address made payable to the full inmate’s name.

Electronic banking allows friends and family members to send the funds online, and correctional departments are starting to favor this method because it is less work for staff and more accurate/easier to keep track of, as well as being more convenient.

Regardless of the method of sending funds, there are several key things you will need to know:
• Inmate’s full committed name
• Inmate’s ID number
• Inmate’s location – or a system like the federal BOP

Before sending any funds you should find out what online transfer companies the institution your inmate is incarcerated in uses. You can find this information on our site by navigating to the facilities page click on the Money Transfer button under the address and phone number. Pay close attention to the rules of the facility. Sometimes they will require money senders to be on the inmate's visitation list. Some correctional facilities have a deposit limit, like $200-300 at a time, but in federal, there is no limit.

Some of the money transfer firms are MoneyGram, Securus Pay, JPay, AccessCorrections, JailATM, and CommissaryDeposit

Who else can access the money you send?

An inmate with fines or restitution will be subject to commissary/trust account garnishment. If the inmate has these financial obligations, they will be extracted from the inmate’s bank account. It may be a percentage or the entire amount depending on the situation. We recommend inmates who are going into their bid contact the counselor and make an arrangement beforehand. If you go in knowing they are taking 20-25% of all deposits is better than have them take it all and you find out in the commissary line when the account is zero.

Why is my inmate asking for more than I normally send?

This is generally a signal that the inmate is doing something they shouldn’t and need money to get them out of or through a situation. It could be gambling, it could be extortion it could be other things you don’t need to know on this forum (for now). Set boundaries with your inmate. Tell them that “this is the amount I can send each month” and that is it. There are no extras beyond the boundary. Also, NEVER send money to the account of another inmate on your inmate’s instruction. This is a sign that something is not right. If the corrections people discover this, and they do more times than not, it will result in some severe disciplinary action to the inmate, and certainly the loss of all privileges.

Who can I call if I suspect something?

We recommend speaking with the counselor or case manager of the facility and using a generic reference if your suspicions are wrong. You needn’t put them in a more difficult position if they are.

Sending Mail to Inmates at TDCJ - Rufus H. Duncan Geriatric Facility (N6): Guidelines and Services

Looking to send heartfelt greetings to your loved one in prison? Some facilities have recently updated their rules for incoming mail to protect staff from potential drug contamination through the ink used in mail pieces.

When sending letters, photos, postcards, greeting cards, and magazines to inmates at TDCJ - Rufus H. Duncan Geriatric Facility (N6), adherence to specific guidelines is essential. Both incoming and outgoing mail undergo inspection to prevent the introduction of contraband that could compromise the safety, security, or well-being of the facility, its staff, and residents.

Inmate mail must not contain content that poses an immediate threat to jail order, such as descriptions of manufacturing weapons, bombs, incendiary devices, or escape tools that could realistically endanger jail security. Content advocating violence, racial supremacy, or ethnic purity is also prohibited. Additionally, inmate-to-inmate mail is not allowed and will be destroyed.

Inmate Commissary

Understanding Inmate Commissary

An inmate commissary, often referred to as a "canteen," is a store within a correctional facility where incarcerated individuals can purchase items not provided by the institution. Commissary services play an essential role in improving the quality of life for inmates by giving them access to additional goods and services. Here's what you need to know about how commissaries function and the impact they have:

What Is Available at Commissary?

Commissary stores typically offer a wide range of products, including:

  • Entertainment Items: Books, playing cards, radios, and sometimes MP3 players or tablets for facilities with digital programs.
  • Clothing and Accessories: Basic clothing, shoes, and thermal wear.
  • Miscellaneous Items: Batteries, headphones, and over-the-counter medications.

How Do Inmates Pay for Commissary?

Inmates use funds from their trust accounts to make purchases. These accounts are funded by money sent from family or friends, as well as wages earned from jobs within the facility. Without available funds, inmates cannot access commissary items unless they qualify as indigent, in which case the facility may provide limited basic supplies like paper and stamps.

Why Is Commissary Important?

Commissary services enhance the overall well-being of inmates in several ways:

  • Comfort: Access to familiar snacks and hygiene products provides a sense of normalcy.
  • Communication: Purchasing writing supplies and stamps enables inmates to stay connected with family and friends.
  • Rehabilitation: Items like books and educational materials contribute to personal growth and development.
  • Autonomy: The ability to choose and purchase items fosters a sense of independence.

Regulations and Limits

Each facility has strict rules governing commissary purchases:

  • Spending Limits: Weekly or monthly caps are set to prevent hoarding or misuse of funds.
  • Item Restrictions: Facilities may prohibit certain products to maintain safety and security.
  • Delivery Schedules: Commissary orders are typically processed and distributed on designated days.

Inmate commissaries provide more than just goods—they offer a vital connection to the outside world and an opportunity for inmates to manage their daily needs.
