What to do if I have a "Certificate of Notice" that says "undeliverable" next to creditors?

The Certificate of Notice confirms that the court sent a notice about your bankruptcy filing to all of the addresses listed on the certificate. The addresses are taken from the creditor matrix you submitted to the court when you filed your case. 

If you notice that one or more creditors are marked as “undeliverable” on the Certificate of Notice, it means that the creditor did not receive what the court sent them because the address was inaccurate. Follow these steps to update the address(es) with the court to make sure these creditors receive the necessary notice of your case.
