How to Label PCI Data in SharePoint Automatically

SharePoint supports basic sensitivity labels, but it does not detect PCI on its own. Without PCI detection, labels cannot be applied correctly or consistently. Native limitations include:

• No automatic identification of credit card or bank account data
• No labeling for PCI DSS categories
• No classification inside PDFs, images, and scans
• No deep content inspection across file types
• No PCI-focused metadata tagging
• No historical classification
• No enforcement rules based on PCI labels

Because SharePoint cannot identify PCI, sensitive data often remains mislabeled or completely unlabeled.

✨What (PCI) Credit Card Numbers Classification Looks Like Inside SharePoint

PCI data often appears in SharePoint documents where users least expect it. Examples of files that should receive PCI labels include:

• Invoices containing full credit card numbers
• Scanned card authorization forms
• Screenshots showing customer payment cards
• Bank statements and ACH forms
• CSVs with account and routing numbers
• PDF exports from payment systems
• Images and receipts uploaded from mobile devices

Strac labels all common PCI patterns, including:

• Visa, Mastercard, AMEX, Discover PAN formats
• 4111 1111 1111 1111
• 4242-4242-4242-4242
• 5500 0000 0000 0004
• Bank account + routing combinations
• IBAN / SWIFT numbers
• PCI hidden inside images or layered PDFs

Each detected PCI element is assigned a classification tag, ensuring files are labeled and governed correctly.

✨What It Means to Label (PCI) Credit Card Numbers in SharePoint

Labeling PCI is more than tagging a file—it establishes a full governance workflow. Once PCI is labeled, organizations can:

• Track where PCI exists across libraries
• Apply retention policies
• Enforce access restrictions
• Prevent external sharing
• Trigger alerts or remediation
• Support PCI DSS audits
• Apply downstream DLP rules

SharePoint’s built-in labels cannot be applied accurately without automated detection.

Strac’s classification engine provides:

• Automatic PCI labeling
• Policy-driven sensitivity tagging
• Metadata enrichment for audits
• Continuous monitoring and relabeling
• Integration with Microsoft Purview sensitivity labels
• Library-level and tenant-wide visibility
• Labels that trigger redaction, blocking, deletion, or alerting
