Review - Getting "Error: Unable to create matter : Display number is too long (maximum is 255 characters)" When Trying to Create a Matter


  • Error: Unable to create matter : Display number is too long (maximum is 255 characters)
  • Matter name too long
  • Unable to create matter
  • Matter character limit


  • Clio Manage

Additional Information:

  • Check the Contact Name to see if there are spaces behind the First and/or Last Name, i.e. if the first and/or last name were copied from an email with spaces behind it.


A certain field that is part of your Matter Numbering Scheme might be causing the Matter Number to go above the 255 character limit


  • Ensure that none of the fields consist of a high number of characters
  • Ensure that there are no extra blank spaces in any of the fields that your Matter Numbering pulls from, this includes but is not limited to the client's First and Last Name, and Matter Description
