Wyoming is the least populous state in the country, with roughly 580,000 people spread across nearly 98,000 square miles. Child support services reflect that geography. Instead of a few large metro offices, the state relies on small offices in county-seat towns and a handful of other communities. Our database lists 12 child support offices in 12 Wyoming cities, from Cheyenne in the southeast to Cody in the northwest. This page explains who runs them, what they can and cannot do, and how to prepare before you call or drive in.

How the Wyoming Child Support Program Is Organised

Child support here is part of a federal-state partnership called the IV-D program, named for Title IV-D of the Social Security Act. Every state must run a program that locates parents, establishes paternity, obtains support orders, collects payments and enforces them. In Wyoming, that work is carried out by the state Child Support Program, administered through the Wyoming Department of Family Services. State agencies are sometimes reorganised, so confirm current contact details by phone before you mail any paperwork.

The rules for setting amounts come from Wyoming law, mainly Title 20 of the Wyoming Statutes, which covers domestic relations and contains the child support guidelines. Judges in the state's district courts sign and change support orders. A local child support office cannot issue a ruling on its own. What it can do is prepare your case, send it to court, and then collect and enforce the resulting order.

The program's attorneys represent the State of Wyoming, not you or the other parent. You can apply without hiring a private lawyer. Questions about custody, visitation or divorce are a separate legal matter, and the child support office will not handle them for you.

A child support case can include any of these services:

Most families deal with the program through phone calls, mail and forms, and meet a local caseworker only when a document or signature is needed. That is why knowing your nearest office still matters.

Child Support Offices Across Wyoming's Regions

Wyoming has 23 counties, and the 12 listings in our database cover 10 of them. Offices sit mostly in county seats along the main highways. If your county has no office listed, the nearest one will usually serve you, so call first and ask which office holds your case.

Southeast Wyoming: Cheyenne and Laramie

The Cheyenne Child Support & Social Service Office is at 2015 Carey Avenue in Laramie County. Its number is 307-635-3365. Cheyenne is the state capital and largest city, at the meeting point of Interstate 25 and Interstate 80. About 50 miles west, the Laramie Child Support & Social Service Office at 1771 Centennial Drive serves Albany County, home of the University of Wyoming. Call 307-742-2026 to reach it. Winter wind and snow often close parts of I-80 between the two cities, so a phone call can save a risky trip.

Central Wyoming: Casper and Douglas

Casper, the second-largest city in the state, is the seat of Natrona County. The Casper Child Support & Social Service Office is at 201 North David Street, and the phone number is 307-235-9229. Families from smaller communities around central Wyoming often route their business through Casper because of its size. In Converse County, Child Support Services of Wyoming operates at 1954 East Richards Street in Douglas and answers at 307-358-0947. Douglas sits on I-25 roughly 50 miles east of Casper.

Northern Wyoming: Sheridan and Newcastle

The Sheridan Child Support & Social Service Office is at 224 South Main Street in Sheridan County, near the Montana line along I-90. Call 307-672-2599. Far to the east, the Newcastle Child Support & Social Service Office at 723 Washington Boulevard serves Weston County, close to the South Dakota border. Its number is 307-746-2311. Newcastle is a long drive from most other offices, which makes phone and mail contact especially useful for families there.

The Bighorn Basin: Cody, Worland and Basin

In Park County, the Cody Child Support & Social Service Office is at 1002 Sheridan Avenue, phone 307-527-8840. Two neighbouring basin towns have offices as well. Basin, in Big Horn County, is listed at PO Box 327 with the number 307-568-9329. Worland, in Washakie County, is listed at PO Box 227 with the number 307-347-8927. A post office box is a mailing address, not a place to walk in. Call before you travel so you know where and when staff will meet you.

Fremont County and the Wind River Reservation

Fremont County has three listings, more than any other county. They are the Fort Washakie Child Support & Social Service Office (PO Box 1573, 307-335-8371), the Arapahoe Child Support & Social Service Office (325 Left Hand Ditch Road, Riverton, 307-857-2436), and a listing in Lander. Much of the Wind River Reservation, shared by the Eastern Shoshone and Northern Arapaho tribes, lies in this county. When a parent is a tribal member or lives on the reservation, ask the office how that affects which court and which enforcement tools apply to your case.

What to Bring and What to Expect at a Wyoming Office

Preparation shortens the process, especially when the nearest office is an hour's drive away. Gather these items before you call or visit:

Ask whether you need an appointment. State offices generally keep weekday business hours and close on state holidays, but hours differ by town, so confirm by phone. Write down your case number and the name of your caseworker after every conversation.

Report changes promptly. A new address, a new job or a change in who the child lives with can alter how your case is handled. If you owe support, keep paying the amount in your order while you ask for a review. Only a court can change that amount, and informal agreements between parents do not erase what the order says.

The child support program in Wyoming is administered by the state's child support enforcement agency, which operates through a network of county-level offices that handle case intake, order establishment, payment processing, and enforcement across the state under the authority of Title IV-D of the Social Security Act.

Child Support Offices locations are available in 12 cities across Wyoming. They are spread across 10 counties.

Cities with the highest concentration include Worland, Riverton, Cody, which serve as regional hubs for child support case processing and interstate enforcement coordination for cases involving parents in multiple states.

Non-custodial parents in Wyoming who are current on their support obligation and experiencing a significant change in income — such as job loss or medical disability — may be eligible to request a formal modification review through the state child support agency without having to hire an attorney.

Custodial parents in Wyoming who receive public assistance are automatically enrolled in child support services as a condition of TANF or Medicaid eligibility. Parents not receiving public assistance can still apply for child support services voluntarily and typically receive the same level of enforcement assistance at little or no cost.

Planning Child Support Business Around Wyoming's Distances and Weather

Few states ask residents to travel as far for routine government business. Before you drive to an office, check the Wyoming 511 travel information service run by the state transportation department. Snow, ice and high wind regularly close stretches of I-80, I-25 and mountain highways. Chain laws and no-travel advisories can apply even when the sky looks clear in town.

Staff at small offices often cover several counties, so you may reach voicemail. Leave your name, case number and a phone number, and say briefly what you need. Families in Sheridan County and other northern areas should also ask whether documents can be sent by mail or scanned, which can replace a trip.

Keep every notice you receive, including envelopes with postmarks. Written records help if you later need to show when you reported a job change or when a payment stopped. If you are unsure whether a letter is genuine, call the office number listed on this page rather than the number printed in the letter.

Often you do not. Many steps can begin with a phone call to the nearest office, followed by forms completed by mail or at the counter. Because Wyoming offices cover large areas, staff are used to parents who live an hour or more away. Ask which documents can be mailed and which need a signature in person. In towns with a street address listed, such as Cheyenne or Casper, you can usually arrange a visit, but confirm hours first. Offices listed with PO boxes, such as Basin and Worland, are best contacted by phone or mail before you travel.

Our database shows three Fremont County listings: Fort Washakie, Arapahoe (with a Riverton street address) and Lander. Which one holds your file can depend on where you live and where the case was opened, so call the closest office and give your name and case number if you have one. Staff can tell you whether your case is handled locally or elsewhere. If you or the other parent is an enrolled tribal member living on the Wind River Reservation, ask how that affects jurisdiction and enforcement. Do not assume the nearest office is the right one.

Yes. Every state has adopted the Uniform Interstate Family Support Act, which lets one state's program work with another's. Wyoming's program can ask the other state's agency to locate the parent, enforce an order or send a wage withholding notice to an out-of-state employer. You usually do not need to travel. Expect the case to move more slowly than a local one, since two agencies and sometimes two courts are involved. Keep your Wyoming caseworker updated on any new address or employer for the other parent, because that speeds up enforcement.

It can, but only through a court. If you lose a job, your income falls or custody changes, ask the program whether you qualify for a review and make the request as soon as the change happens. Support orders generally cannot be reduced for months that have already passed, so waiting can leave you owing amounts you cannot undo. Until a judge signs a new order, the old amount stays due, even if you and the other parent agree on something different informally. Keep pay stubs, termination letters and other proof to support your request.

Most support is paid through income withholding. The employer takes the amount from each paycheck and sends it to the state, which then passes it on to the receiving parent. Follow the instructions in your order about where payments go, because paying the other parent directly may not be credited on the state's record. If payments stop, give your caseworker the date of the last payment and any employer change you know about. Ask your office how payments are issued, for example by direct deposit if available, and keep your banking and mailing information current.

Be cautious. The program collects through wage withholding and official payment channels. It does not demand gift cards, cryptocurrency or wire transfers to an individual. If a caller pushes you to pay immediately, hang up and phone the office yourself, such as 307-635-3365 for Cheyenne or 307-235-9229 for Casper, and ask whether your case has a real problem. Never give your Social Security number to an unsolicited caller. Genuine staff can discuss details of your case and will also send written notices by mail.
