Obtaining Information About Your Case

Instructions for Requesting a PIN Number

CSSD personnel cannot give PIN information over the telephone, so the information is always mailed to the address on file for the person requesting the PIN.  After requesting a PIN, please allow five to seven business days for it to arrive in the mail. 

Customers may request that their PIN number be sent by following these instructions:

  • Dial CSSD’s main customer service number (202) 442-9900
  • Press “1” for English, or “2” for Spanish
  • Press “1” for information on a specific case
  • Enter your social security number at the prompt
  • The next prompt will ask for a PIN, then it will say “if you don’t know your PIN, please press the pound (“#”) key, now”, press “#”
  • Press “1” to have your PIN number mailed to you

Customers may also request their PIN number from any computer that has access to the internet by following these instructions:

  • Go to the Online Case Lookup Login Page
  • Select the “New User Registration” button
  • Select the “Request PIN” button
  • Enter the required information, and select the “Submit Request” button
