TYPE OF MAIL ALLOWED FOR the Cook County Department of Corrections

The Cook County Department of Corrections has a very strict set of rules and policies regarding mail that is delivered to inmates.

The purpose of these rules are not to make life difficult for you or to ‘punish’ incarcerated inmates further, but are here for the safety and security of all the inmates and staff who reside and work in what can be a very dangerous place.

 For the time being, Cook County Department of Corrections is still allowing inmates to receive physical mail, however many jails and prisons around the country are starting to go full-on digital; only allowing electronic messages and digital images to be accessible by inmates through kiosks or jail provided handheld devices.

All Cook County Jail Inmates are made aware of the following Rules and Policies and for your benefit these are posted here.

Many items that are needed by inmates that you may want to mail but can’t, can be purchased directly from the Cook County Jail’s Commissary. Even indigent inmates, those without any funds, are provided basic hygiene items and other items necessary for their physical and mental health.

Cook County Department of Corrections Inmates are allowed mail in envelopes and on postcards.

They are also allowed to receive books and magazines, but only a maximum of three per mailing. Newspapers are not allowed.

What is Inmate mail?

By law, every inmate is entitled to receive mail delivered through the United State Postal Service. While for years, this mail was always delivered in the form of a letter or a postcard from friends and loved ones directly to the inmate, the definition of inmate mail has changed a bit.

Inmate mail can be:

•    A letter in an envelope,
•    A postcard,
•    A greeting card, or
•    A digital letter

Because of security and contraband concerns, mainly the paper and envelope that a letter is written on or enclosed in, being soaked in a liquid form of drugs, many jails are increasingly limiting the type of mail inmates can get.

Some still allow regular mail in an envelope with a stamp, but many now have the letter sent to a third-party that opens the letter, scans it and the envelope into a computer, emails the letter to the jail where they print it out, giving the photocopies to the inmate, or they send it to a computer kiosk or tablet digitally that the inmate can access.

Others only allow postcards, specifically the white, pre-stamped postcards that you can purchase from the post office. 

When greeting cards are allowed, they can’t be cards with glitter, music or other do-dads. They can only be plain paper cards.

Some jails, in fact most, require that mail be written or typed with only black or blue ink. Some allow black pencils to be used.

None allow crayons, markers, lipstick prints, etc. 

All require white envelopes, white paper or lined paper such as from a pad. Very few allow paper that is card stock. It must be plain white, 20-lb. printer paper.

To see the inmate mail policies for Cook County Department of Corrections check out the inmate mail details above or call the jail at 773-869-7100 for specific information.


 

 

What is my inmate’s mailing address?

There are five different types of addresses for every jail:

1.    The physical address of the jail.
2.    The mailing address for an inmate’s personal mail.
3.    The mailing address for the inmate’s legal mail.
4.    The mailing address for the jail’s administrative staff.
5.    The mailing address for sending money to the inmate’s trust or commissary fund. (visit the Inmate Money page for this information)

In general, the only three addresses that friends and family of inmates need to be concerned about are:

•    The inmate address for personal mail.
•    The address for sending money orders to the inmate’s commissary account.
      Visit the Inmate Money page for this information.
•    The physical address of the jail.

Because this section is about mailing an inmate, the address for mailing an inmate is:

Inmate's Full Name & Booking #
Cook County Jail
2700 S. California Ave.
Chicago, IL 60608

or 

Inmate's Full Name
Inmate ID#
Cook County Department of Corrections
2700 South California
Chicago, IL 60608

If a red address is visible above, then use that address, as that is the new address the jail is using for an inmate's personal mail to combat contraband entering the facility.


 

 

How do I mail a letter to an inmate in the Cook County Department of Corrections?

To mail a letter to an inmate in the Cook County Department of Corrections, first completely read all the mail policies and guidelines that are on this page. Also read any updated mail guidelines that are on the official page for the facility. If you still have questions, then call the jail at 773-869-7100 and ask specifics.

It is important to understand that if even one thing is done incorrectly when sending a letter to the jail, even if everything else is done correctly, then your letter will not be delivered to the inmate.  In fact, even though the jail claims they will mail your letter back to you so that you will know it was not delivered, there is always the chance it will be disposed of. 

Don't be the loved one sitting at home, wondering why your inmate is not responding to your letter, when in fact they may not have even received it.


 

 

How do I address a letter to an inmate?

All mail to the inmate must be addressed as follows:

A full return address, which includes your full name and full address.  Without this the mail will not be delivered to the inmate.

A complete address to the inmate, including:

Full Name (name that they were booked under)
Inmate ID# (booking #, SO #, etc.)
Inmate’s Housing location (if you know it)
Cook County Department of Corrections
Mailing Address
City, State, Zip code

Inmate's Full Name & Booking #
Cook County Jail
2700 S. California Ave.
Chicago, IL 60608



A letter that is not addressed completely may not get delivered. Keep in mind that often there is more than one inmate in a jail with the same name. You certainly don’t want the wrong inmate getting your private mail, do you?


 

 

If a letter is withheld from being delivered to an inmate, will they be notified?

Sometimes. There are some jails that will deliver you a notification that a letter which was intended for you was returned because it was either improperly addressed, did not have return address, contained contraband of some sort, had things written in it that were against mail and jail policies, or were sent by someone you were not allowed contact with such as co-defendant or someone the court had forbidden contact with such as a spouse in a domestic violence case.

Most of the time though, the letter is either returned or destroyed, and if there are illegal substances in the letter, it will be turned over to the Cook County Sheriff or District Attorney for possible criminal investigation and/or indictment.


 

 

What can I send to an inmate by mail?

Generally nothing but a letter, printouts from a computer printer or photographs (not polaroid) can be sent to an inmate in the mail. If there is anything else enclosed, the entire letter and the contents will be returned to you or destroyed.

There are a few exceptions to this, such as several county jails in New York, including the infamous Riker’s Island. Riker’s allows all kinds of things to be mailed to an inmate, including a box of items every month.


 

 

Can I send pictures to an inmate?

Every jail has their own policy regarding allowing inmates to receive photographs in the mail, if at all. For Cook County Department of Corrections’s policy, review the information on this page.

In general, most jails allow an inmate to have anywhere from four to six photographs in their possession at any one time. These cannot be polaroids, and the photos cannot be construed as even mildly sexual (such as a woman or child in a bathing suit), gang related, drug related or violent.

Some jails allow only photocopied photos.

Some jails only allow photos that are sent digitally and must remain digital.

There are only a few jails that do not allow any photos of any kind.

If you are still uncertain as the policy regarding photographs at the Cook County Department of Corrections, call them at 773-869-7100.


 

 

Can I send newspapers, magazines and books to an inmate in the Cook County Department of Corrections?

Most jails allow newspapers, magazines and books to be sent to an inmate, as long as they come directly from the publisher, such as directly from the newspaper or magazine themselves, or from the specific book publisher or trusted mail order source such as Amazon or Barnes and Noble.

There is often a limit of the quantity of books and magazines an inmate can either receive at one time, receive each month, or have in their possession at any one time. 

Hardcover books, or books with wire spiral binders are never allowed.

Any publications that portray or discuss violence, sex, gang activity, drugs, jail escapes or anything else against jail policies are not allowed and will be returned.

The 'book and periodical' policy of the Cook County Department of Corrections are detailed on this page. However, if it is not, then call the jail at 773-869-7100 and ask.

Keep in mind that the address the publications should be mailed to is not always the mailing address of where the inmate gets their regular mail, the mail that is scanned and forwarded digitally to them.

The mailing address for publications is:

Inmate's Full Name & Booking #
Cook County Jail
2700 S. California Ave.
Chicago, IL 60608


or 

Inmate's Full Name
Inmate ID#
Cook County Department of Corrections
2700 South California
Chicago, IL 60608

NOTE: Use the address in red if it is visible to you.

Exception: There are a few New York jails that allow publications to be sent directly to them as opposed to having it sent through the publisher. One of the most notable exceptions is Riker’s Island in New York City.


 

 

How often can I send letters or cards to an inmate?

There is no limit to how often you can send letters or cards to an inmate. You are only limited to the types of letters and cards that you can send, considering Cook County Department of Corrections’s policies, which are outlined on this page.


 

 

How often can an inmate mail letters?

An inmate in the Cook County Department of Corrections can mail letters as often as they like.  There is no limit to the number of letters that an inmate can write and send.  They are only limited by the number of stamps they can afford to purchase through commissary, and the amount of commissary 'spend' that the Cook County Department of Corrections allows.


 

 

What is considered ‘contraband’ in an inmate’s mail?

Contraband is defined as anything that the jail does not allow to be mailed to an inmate, which is just about everything. The list would fill ten sets of encyclopedias. 

It easier to say what is allowed to be sent through the mail:

•    When allowed, a certain number of photographs.
•    When allowed, newspapers, magazines and books, if they are sent from a publisher.
•    When allowed, a care package of snacks, hygiene products or clothing from a commissary company that has contracted with the jail.


 

 

Can I send printouts from my computer to an inmate?

Some jails allow printouts of photographs and information to be sent to an inmate through the mail. Refer to the mail policy on this page or by calling the jail directly at 773-869-7100.


 

 

Can I send an inmate a package?

Many jails contract with companies that send food, hygiene products and/or clothing to inmates. These can be purchased and sent by friends and family on a weekly or monthly basis.

You can only send items from the one that your jail has a contract with. 

Check out the Money Page or the Commissary Page for further information, or call the jail at 773-869-7100 to see which one that the Cook County Department of Corrections works with.

Can I send an inmate a gift?

The only gifts you can send an inmate must come from one of the stores above, and the Cook County Department of Corrections must contract with them.


 

 

If I send something to an inmate that is not allowed, can the inmate or I get in trouble?

If the item that you send an inmate is illegal, then you and/or your inmate can get in trouble, otherwise if it is not illegal, it will just be destroyed or in some cases, returned to you.

Note that if you continue to send items that are considered contraband, some of your communication privileges with your inmate, such as visitation or phone calls, may be suspended.


 

 

Can I send an inmate postage stamps?

No, you cannot send postage stamps. Stamps must be purchased by the inmate through commissary. You can send them the money for stamps, but not the stamps.


 

 

How can an inmate get stamps while in jail or prison?

Stamps can be purchased in the jail commissary by the inmate.


 

 

If an inmate has no money, will the Cook County Department of Corrections give them stamps?

Yes. If an inmate is indigent, the jail will provide them 2-3 stamps, and an equal amount of envelopes and stationery, each week. 


 

 

What happens if I send the inmate drugs, a weapon or anything illegal, will I get in trouble?

Yes. If you send the inmate drugs, a weapon or anything illegal, it will be turned over to the Cook County Sheriff or District Attorney and it is most likely that you will be prosecuted. 


 

 

What are some other important mail tips to avoid problems?

  • Mail is always scanned and inspected for contraband, obscenity and other rule infractions.

  • Never write anything about the inmate's court case you wouldn't want read aloud in court.
  • Mail is considered by the jail to be a privilege. Any violations of the mail policies can result in the inmate's mail privileges being suspended.
  • The introduction of contraband by you into the jail through the mail could result in criminal charges being filed against both you and the inmate.
