There is no national child support fax number. Child support is run by each state, and the right fax depends on your state and the document. Verified examples: the Florida Department of Revenue takes returned child support forms at 850-921-0792; California DCSS takes state hearing requests at 916-464-5069; and in Texas, the Child Support Disbursement Unit takes direct deposit forms at (210) 924-4104. Always check your case letter first.

This guide lists the verified state numbers, explains how to find your own state's agency, and covers what to put on every page.

  • State agencies run child support, so numbers vary by state
  • Verified numbers for Texas, California and Florida, from official state sites

How child support agencies work

Every state runs a child support program that establishes paternity, sets and enforces orders, and collects and pays support. Some states run it centrally (Texas through the Office of the Attorney General, Florida through the Department of Revenue); others, like California, have a state department that works through local county agencies. Payments usually go through a separate State Disbursement Unit.

So the right fax depends on what you're sending: a payment form, a hearing request, or case documents.

Finding your state's agency

The federal Office of Child Support Services (OCSS) keeps a map of every state and tribal child support agency at acf.gov. To find the right fax:

  1. Read your case letters. They name the agency and usually give a fax or upload option.
  2. Sign in to your state's child support portal, where many states let you upload documents.
  3. Call the agency's customer service line and ask which fax handles your document.

How to fax child support, step by step

  1. Find the agency and fax from your letter or the table.
  2. Use the agency's form if one exists, such as a direct deposit or hearing request form.
  3. Write your case number and name on every page.
  4. Attach supporting documents, such as pay stubs or a court order, if requested.
  5. Fax it and keep the confirmation.

You can send a fax online for $2.99 with no subscription and no account.

Mistakes that slow down a child support case

  • No case number on the pages.
  • Payment forms sent to a case office, or case documents sent to the disbursement unit.
  • Using another state's fax. Your case stays with the state that manages it.
  • Missing a hearing deadline. Check your notice for the date.
