Equifax releases details on last year's breach.


Equifax is offering a closer look at its massive data breach, which revealed sensitive information on more than half the American population last year.

The company released the details Monday in a Securities and Exchange Commission filing, following demands from US senators.

The credit-monitoring company, which gathers personal information on people without being required to notify them, has provided some details in the past about the breach, including that 146.6 million Americans were affected and that their Social Security numbers, names, birthdates and addresses were stolen.

Here is the breakdown from Equifax on how many people were affected by category:


146.6 million


146.6 million

Social Security Number

145.5 million


99 million


27.3 million

Phone Number

20.3 million

Driver's License Number

17.6 million

Email Address

1.8 million

Credit Card information


Tax ID


Driver's License State


Hackers also stole thousands of photos uploaded to Equifax's servers that came from passports and driver's licenses. Up to 182,000 people had uploaded images to Equifax's server, the company said. 

Here's the breakdown of images stolen:

Driver's License


Social Security or Taxpayer ID card






These numbers only detail US residents affected by the breach, even though Equifax noted that some people in the United Kingdom and Canada were also affected.

"Through the company's analysis, Equifax believes it has satisfied applicable requirements to notify consumers and regulators," the company said in its SEC filing.

An Equifax spokeswoman responded to a request for comment by referring back to a statement from the company. In the statement, Equifax noted that it shared this same information with members of Congress on Friday.

While Equifax's data breach isn't the largest in history -- that record belongs to Yahoo, which reported that up to 3 billion accounts were compromised -- Equifax's hack has much more potential for damage considering the types of data stolen.
