We are scheduled for an Unannounced Audit for SQF Packaging in 2021. I am told our boundary dates fall from beginning of October to beginning of December 2021. Today I received an email from our certification body with the dates for a two day Audit! This being our first unannounced I am confused as to why we were given a date. Doesn't an auditor just show up one day within your boundary dates to "surprise" audit the facility or were we really given a legitimate date as per the email?
