HELP! I have a problem. Who do I call?

  1. If you received an authorization receipt but see an error message on the bottom of your receipt stating, "error in updating ICMS," this is an indication that your payment did not process successfully. Please try again.

  2. If you have any of the following:

    • Traffic school questions
    • Need an extension on your citation
    • General questions and processing of your citation
  3. Please visit the courts website at www.sanmateocourt.org/court_divisions/traffic or contact the court Traffic Division at (650)363-4300.

  4. If you receive an error message when trying to pay online, yet your bank or credit card company is confirming that the transaction went through, this is an indication that your payment did not go through. The bank or credit card company holds the amount charged as a pending transaction. Generally, within 24 to 72 hours, the bank or credit card company will realize the payment did not go through and will release the amount back to your account. During this time, you must contact the Traffic Division regarding other options for paying your citation or you can try to pay online again later.

  5. If you receive a 203 error or a "Citation Cannot be Found" message when you enter your citation/ticket/case number, this is an indication that there may be a duplicate citation number or the citation has not yet been entered into the system. Please contact the Traffic Division for further assistance.

  6. If you have trouble accessing the system, please contact ISD Corporation at epsupport@isd-corp.com
