How to Call Child Support

Last updated: July 31, 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.

Finding your state child support office

Your first step is finding the right number. Here's how:

What to have ready

Child support caseworkers need specific information to pull up your case. Having these ready will save you time:

Getting through the phone tree

Most state child support offices use automated phone systems. The exact menus vary, but here's a general approach:

  1. Call your state child support office number
  2. Select your language
  3. Enter your case number or Social Security number when prompted
  4. You'll typically hear automated options for payment info, case status, and more
  5. To reach a caseworker, press 0 or select "speak to a representative"
  6. 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

Common questions

What is the child support phone number?

There is no single national child support phone number. Child support is administered by each state. Visit acf.hhs.gov/css/contact-information/state-and-tribal-child-support-agency-contacts to find your state's child support office phone number.

How do I check my child support payment status?

Call your state's child support office and provide your case number. Most states also offer online portals where you can check payment history, upcoming disbursements, and arrears balance. Ask your state office for their website URL.

How do I request a child support modification?

Call your state child support office and request a review of your order. You'll typically need to show a major change in circumstances — like job loss, a new job with different pay, a change in custody, or a medical issue. The office can initiate the review process.

What if my child support payment is late?

Contact your state child support office with your case number. They can check whether the payment was processed, if there's a delay with the employer's payroll, or if enforcement action is needed. Processing times vary — direct payments typically take 2 to 3 business days.

What is the federal Office of Child Support Enforcement?

The Office of Child Support Enforcement (OCSE) is the federal agency that oversees state child support programs. They don't handle individual cases, but they provide resources and can direct you to your state office. Their website is acf.hhs.gov/css.

Let Mio hold for the child support office

Payment status, a modification, an enforcement question — tell Mio your state office and what you need. It dials, navigates the menu, and waits. When a caseworker picks up, Mio calls you and connects you.

Only pay when Mio gets you through — nothing if it doesn’t.
