Most identity theft steals a whole person — your name, your number, your accounts. Synthetic identity theft does something stranger and harder to catch: it stitches together real and fake details to build a brand-new “person” who does not exist, then uses that invented identity to borrow money no one ever repays. Our GetMyPassword team explains what it is and how to protect yourself.
What synthetic identity theft is
Synthetic identity theft combines real and fabricated information to create a new, fictitious identity. A criminal might pair a real Social Security number — often a child’s, an elderly person’s, or anyone with little credit activity — with a fake name, date of birth, and address. They then use this hybrid identity to apply for credit. Early rejections actually help them: each application can create a credit file. Over time they build up credit, borrow as much as possible, and disappear, leaving the debt attached to a person who was never real, while the borrowed number may belong to you.
Why it is so hard to detect
- No single victim is obviously robbed, since the identity is partly invented.
- The real number’s owner may not notice, especially a child or someone who rarely uses credit.
- It builds slowly, looking like a normal new credit history.
- Lenders see a “real” file, not an alarm, until the debt goes unpaid.
- The fictitious person cannot be “found” after the fraud.
Who is targeted and how to spot it
Because the scam favors numbers with little activity, children and seniors are frequent targets — a child’s unused Social Security number can go misused for years. Warning signs include receiving credit offers, bills, or collection notices in the name of a child, or a credit file existing for someone who never opened one. For adults, unexplained accounts or inquiries on your report can be a clue. Checking the credit reports of family members, including minors, and watching your own, is the main way these invented identities come to light.
Synthetic identity theft does not impersonate you — it builds a stranger around your number. A child receiving a credit offer is not junk mail; it can be the first sign of a debt being assembled in their name.
How to protect yourself and your family
Guard Social Security numbers, especially your children’s, and consider a credit freeze for minors and for yourself, which blocks new credit in your name. Watch your credit reports and check whether a file exists for a child who should have none. Shred documents with sensitive numbers and limit where you share them. Because the data that fuels these scams often comes from breaches and phishing, keep your accounts behind a unique password from our password generator and two-factor authentication.
Frequently asked questions
What is synthetic identity theft?
It is a fraud that combines real information, like a Social Security number, with fabricated details to create a new fictitious identity. Criminals use it to build credit and borrow money that is never repaid, leaving debt tied to a person who does not exist.
Why are children targeted?
A child’s Social Security number usually has no credit activity, so misuse goes unnoticed for years. Receiving credit offers, bills, or collection notices in a child’s name is a warning sign of synthetic identity theft.
How do I protect against it?
Guard Social Security numbers, consider credit freezes for yourself and your minor children, monitor credit reports, shred sensitive documents, and secure your accounts with unique passwords and two-factor authentication to limit the data breaches that fuel the fraud.
