What is Personally Identifiable Information (or “PII”)?

Personally Identifiable Information (“PII”) has become a buzzword in the privacy law world the last few years, and it is heavily protected by rules and regulations around the world, such as the General Data Protection Regulation (GDPR). Companies that fail to comply with regulations such as the GDPR, or that suffer a data breach, face steep penalties and/or burdensome, mandated mitigation and reporting requirements.

Because of this, companies, both large and small, across the world, have started to familiarize themselves with the term and their obligations with respect to it.

As per usual, this picture has literally nothing to do with the content of this post. But it’s soothing, so we’ll keep it.

So, that begs the question: what exactly is it?

At the risk of being a jerk: it depends on who you ask! Changes to privacy laws have been rapid-fire over the last few years, and the definition of what’s considered “personally identifiable information” expands each time a new law is enacted.

Generally, PII is one or more pieces of data that can be used to identify a person with particularity. Below, we’ve compiled a (non-exhaustive but exhausting!) list of things that may be considered PII under the law. Some of these may only currently apply in certain states or jurisdictions. But, as the trend in privacy law is to add to this list instead of delete from it, we want to present you with the most inclusive list possible. Here we go!
