Your 7-digit case number, sometimes referred to as a “Bankruptcy Petition Number,” can be found on the paperwork sent to you by the Office of the Chapter 13 Trustee assigned to your case.
Example:
Certain Trustee Offices will add extra characters as part of their office case numbering convention. For example, if your case number looks like 6:11-bk-12345-WJ, your 7-digit case number would be 11-12345. Likewise, for BK00531329 or BK9-05-012345-00, your case number would be 05-31329.
