How to Call Child Support
Last updated: March 19, 2026
Child support isn't run by one federal office you can call — it's administered by each state individually, which means the phone number, hours, and process depend entirely on where your case is. The federal Office of Child Support Enforcement (OCSE) oversees the system, but your state office is where things actually happen. The U.S. child support program collects roughly $34 billion annually for families across the country (OCSE Preliminary Report). Here's how to reach the right office and what to say when you get through.
- State offices acf.hhs.gov/css/contact-information/state-and-tribal-child-support-agency-contacts
- Federal OCSE acf.hhs.gov/css (information and state directory)
- Hours Vary by state — most are Mon – Fri, 8 a.m. – 5 p.m. local time
- Avg hold time 10 – 40 minutes depending on state and volume
- Best time to call Mid-week, early morning
- What you'll need Case number, SSN, court order details
Finding your state child support office
Your first step is finding the right number. Here's how:
- Go to acf.hhs.gov/css and find the state directory
- Look up your state's child support enforcement agency
- Many states also have county-level offices — call the state line and they can direct you to your local office if needed
- If your case involves two states (for example, you live in one state and the other parent lives in another), call the state where your order was issued
What to have ready
Child support caseworkers need specific information to pull up your case. Having these ready will save you time:
- Case number (on any correspondence from your state office)
- Social Security number
- Full legal names of both parents
- Court order details — the issuing court, order date, and order number if you have it
- Recent pay stubs or income documentation if you're requesting a modification
- Payment records — receipts, bank statements, or your state's online payment history
Getting through the phone tree
Most state child support offices use automated phone systems. The exact menus vary, but here's a general approach:
- Call your state child support office number
- Select your language
- Enter your case number or Social Security number when prompted
- You'll typically hear automated options for payment info, case status, and more
- To reach a caseworker, press
0or select "speak to a representative" - Some states route you to a specific caseworker assigned to your case — if so, you may need to leave a voicemail and wait for a callback
A note on callbacks: many state offices are understaffed. If you leave a voicemail, give it 2 to 3 business days before calling again. Keep a log of when you called and who you spoke with.
Checking payment status
What to say
"I'm calling to check on a child support payment. My case number is [number]. I'm the [custodial / noncustodial] parent. I'm looking for the status of [this month's payment / a payment that was due on (date) / my arrears balance]. Can you tell me when the last payment was processed and when I can expect the next one?"
Most states process payments through a State Disbursement Unit (SDU). Payments from employers typically take 2 to 3 business days to process. Direct payments may take longer depending on the method.
Requesting a modification
Life changes — job loss, a raise, a new child, changed custody arrangements — can all be grounds for modifying a child support order. You can't just stop paying or change the amount on your own. It has to go through the system.
What to say
"I'd like to request a review and modification of my child support order. My case number is [number]. My circumstances have changed — [I lost my job on (date) / my income has changed substantially / custody arrangements have changed]. What's the process to request a modification, and what documentation do I need to provide?"
Reporting non-payment or requesting enforcement
If you're the custodial parent and payments aren't coming through, your state office has enforcement tools — wage garnishment, tax refund intercepts, license suspension, and more.
What to say
"I'm calling because I haven't received child support payments. My case number is [number]. The last payment I received was on [date]. The noncustodial parent's information is [name, any known employer or address details]. What enforcement actions can be taken on my case?"
Setting up or changing direct deposit
What to say
"I'd like to [set up / change] direct deposit for my child support payments. My case number is [number]. I have my bank routing number and account number ready. What information do you need from me?"
Tips for calling child support
- Call early in the week, early in the day. Monday morning lines can be busy, but Tuesday and Wednesday mornings are often the best time to reach someone.
- Check your state's online portal. Over 40 states now offer online case management where you can check payments, view your balance, and sometimes submit modification requests without calling.
- Keep records of everything. Write down the date, time, name of the person you spoke with, and what they said. This documentation can be valuable if there's ever a dispute.
- Ask for your caseworker by name. If you've been assigned a specific caseworker, ask for them directly. It avoids rehashing your case from scratch each time.
- Be patient and factual. Child support can be emotionally charged. Staying calm and sticking to the facts gets you through the call faster and gets you better results. The caseworker isn't the other parent — they're there to help.
- Follow up in writing. After any important call, send a written summary to your caseworker (email if available, or mail). This creates a paper trail.
