Understanding Personally Identifiable Information (PII): What It Is and Why It Matters for Your Business
Small businesses collect customer data every day: names, email addresses, payment details, and maybe even Social Security numbers. But do you really know what qualifies as Personally Identifiable Information (PII) and, more importantly, how to protect it?
PII is any information that can be used to identify an individual. That includes obvious details like full names, home addresses, and phone numbers, but also less obvious data, like IP addresses, biometric data, and login credentials. If your business stores, processes, or transmits PII, you’re responsible for keeping it secure.
So why does this matter? Because cybercriminals want PII. Stolen personal data can be sold on the dark web, used for identity theft, or exploited in phishing scams. And if your business is the source of a breach, that could mean legal trouble, fines, and — worst of all — a loss of consumer trust.
PII Laws Vary by State—What That Means for Your Small Business
When it comes to PII in the United States, there’s no single national standard for how businesses must protect it. Instead, each U.S. state has its own regulations, creating a patchwork of laws that small businesses need to navigate. If you collect, store, or process PII from customers across multiple states, compliance can get tricky.
Why Do PII Laws Vary by State?
Some states take data privacy very seriously (I’m looking at you, California), while others have looser regulations. The reason? Data privacy isn’t just about security, it’s also a political and economic issue. States balance consumer protection with the business community’s needs, which is why some enforce strict mandates while others rely on general consumer protection laws.
For example:
California (CCPA/CPRA) is one of the strictest PII regulatory frameworks requiring businesses to disclose data collection practices and allowing consumers to opt out of data sales.
New York (SHIELD Act) mandates "reasonable" security measures, even for businesses outside New York that handle New Yorkers’ data.
Texas and Florida have evolving data breach notification laws but fewer proactive consumer rights like California or New York.
Other States have minimal PII-specific laws, mainly requiring breach notifications.
What This Means for Your Small Business
Where Your Customers Live Matters. If you do business across state lines, you must comply with the laws of the states where your customers reside. Being aware of their data breach and consumer protection laws is important.
You May Need a Privacy Policy. Most states require businesses to publish how they collect, store, and share consumer data.
Data Breach Reporting is Not Universal. Depending on the state, you might have to report a breach immediately or within a set timeframe, only if a threshold of affected consumers is met. Understanding those requirements and thresholds is central to crafting good policy.
Non-Compliance Can Get Expensive. Some laws allow consumers to sue businesses for mishandling PII, leading to fines, lawsuits, or reputational damage.
How to Stay Ahead
Take an Inventory. What is PII? Where is it stored? How is it maintained? Build an awareness with your team about its importance.
Know Your Customers. If you serve Californians, comply with the CCPA. If you have New York clients, follow SHIELD Act rules.
Implement Strong Security. Even if your state has weak PII laws, data breaches hurt your business. Encrypt data, train employees, and enforce access controls.
Stay Updated. PII laws change constantly. Partner with a legal or IT consultant to stay compliant.
While federal data privacy laws might eventually unify regulations, small businesses can’t wait—staying informed and proactive is the best defense. Protecting PII isn’t just about compliance — it’s about maintaining trust with your customers. A single breach can undo years of hard work, so take the right steps to keep your customers’ data safe.
