In PowerSchool SMS, the system utilizes a packaged file specifically named RptPckg.zip to upload and run a bundle of supplemental reports.

If you received a text message regarding a "Zip Code" package error or impersonating the financial company Zip, it is a smishing (SMS phishing) attempt. You can report these texts by:

PowerSchool SMS Report Package * The PowerSchool SMS Report Package contains a variety of reports that supplement PowerSchool SMS' PowerSource How to Report - Zip Help Centre

If you are working with hardware like Trend Micro's TippingPoint SMS, you can use the SMS Diagnostic Toolkit to compile and create a Logs Zip file to assist support teams with troubleshooting.
