Messages, mail, money
ICE's rules for mail, packages and money
Before sending packages to detainees:
The jail will not accept certain items through the mail. Restricted items include packages, obscene or pornographic materials, personal checks, cashier’s check, postage stamps or stamped envelopes, any type of food, or periodicals not directly sent from the publisher.
Mail should be addressed in the following manner:
Detainee’s full name
Natrona County Detention Center
201 N David, 2nd Floor
Casper, WY 82601
Letters sent to detainees must include the last four digits of the detainee’s A-number (File Number), plus the sender’s name and address. To enhance the safety of the facility, all incoming mail is subject to screening for contraband. The mail is not read upon opening, only inspected by the delivering officer. Detainees may send mail from the facility. Detainees may seal their outgoing letters and place them in the provided receptacle. All incoming mail will be delivered to the detainee, and outgoing mail will be routed to the proper postal office within 24 hours of receipt by facility staff. A mail pick-up and delivery schedule is posted in all housing units.
Detainees are allowed to purchase stamps for use. Generally, there is no limit to the amount of correspondence detainees may send at their own expense. Indigent detainees (those who have no means of financial support and no funds in their facility account) will be provided postage allowance at government expense.
When detainees depart the facility or are transferred to another facility, only their legal mail will be forwarded to them. General correspondence will be endorsed "Return to Sender" and returned to the post office. Information about sending money can be found at Sending Money Policy/Account Hours | Natrona County, WY.
A detainee may receive items that are determined to be of necessity for the sole purpose of travel or release from agency custody with approval of the ICE Deportation Officer. Before sending packages to detainees: contact the Casper, WY Sub-Office at wyomingero@ice.dhs.gov or via phone at (307) 462-5025
Note that detainees being removed from the United States are allowed one small piece of luggage. If a detainee does not have such baggage, such luggage can be sent/delivered after receiving approval from Supervisory Deportation Officer. Please be advised that for security reasons, no electronic devices (cell phones, electric razors, laptop computers, radios, etc.) will be accepted.

About these numbers

"Held per day" is the average number of people in custody here each day, computed from ICE's own individual records (names removed) that the Deportation Data Project obtained through FOIA litigation. They run through Aug 5, 2026. A stay counts the time at this facility only; people are often transferred. Shares and averages based on fewer than 10 people are not shown. How we count
