On October 1, it was announced that approximately 15 million T-Mobile customers were impacted by a T-Mobile data breach at credit agency Experian PLC, the latest major leak of confidential data to hit corporate America.

The exposed data included names, addresses, birth dates and encrypted Social Security numbers, driver’s license or passport numbers for customers who might have applied for T-Mobile cell service between Sept. 1, 2013 and Sept. 16, 2015.

T-Mobile said the T-Mobile data breach was discovered on September 15 and included information on millions of their subscribers, former customers and people who applied for service or device financing at the wireless carrier over the last two years.

“Obviously I am incredibly angry about this data breach and we will institute a thorough review of our relationship with Experian,” T-Mobile CEO John Legere said. “I take our customer and prospective customer privacy VERY seriously.”

Experian is one of the three major American credit bureaus, along with Equifax and TransUnion, that affect, if not touch every American with a credit card or cell phone.

There is no evidence yet that any breached information has been inappropriately used and Experian is notifying the individuals who may have been affected. They are also offering free credit monitoring and identity resolution services for two years to affected customers.

Hackers typically put this type of information up for sale on black markets, where large data bases of information are aggregated and sold to identity thieves. A stolen identity can lead to stolen tax refunds, ruined credit and worse.

T-Mobile is in the process of reaching out to people who may be impacted by the T-Mobile data breach.

Here are four steps to take if you are ever afraid your personal data has been breached. All four steps can be done by calling each of the three credit bureaus (Experian: 1-888-397-3742, Equifax: 1-800-525-6285, and TransUnion: 1-800-680-7289).

  1. Monitor your credit reports. You are entitled to one free credit report every 12 months from each of the three credit bureaus.
  2. Consider placing a “fraud alert” with each of the three credit bureaus. An alert doesn’t block potential new credit, but places a comment on your history. Creditors should contact you prior to opening a new account.
  3. Consider placing a “security freeze” with each of the three credit bureaus to prohibit the release of any information from your reports. A security freeze can help prevent identity theft since most businesses won’t open credit accounts without checking a consumer’s credit history first.
  4. Beware of unsolicited calls or emails offering credit monitoring or identity theft services. Never provide your Social Security number, credit card numbers, or other personal information in response to unsolicited emails or calls.
