Synthetic identity fraud.
In plain English
Synthetic identity fraud creates a person who does not exist, stitching a real Social Security number together with a made-up name, birth date, and address that belong to no real person. The number is frequently taken from a child or from someone who does not use credit, because nobody is watching that file. Small credit applications get filed until an inquiry creates a file at the credit bureaus, then the fake profile is nurtured with tiny accounts paid on time until limits grow. The scheme usually ends in a bust-out, where every line is maxed at once and abandoned.
01Why it matters
Because the name attached to the file is not yours, this fraud can run for years without ever appearing on your credit report, which is why freezing a child's credit and reading your own report are the practical defenses.
02The math, step by step
A fake profile opens with a $300 secured card, pays on time for 18 months, grows to $40,000 in combined limits, then draws all of it and vanishes. No individual person ever received a bill.
Illustrative example. The amounts here are hypothetical, chosen to show how the math works, not real quoted rates or figures.
03What this is NOT
In classic identity theft, someone uses your full identity, so the bills and credit report entries come back to you. Synthetic fraud borrows one piece, usually a number, and attaches it to a different name. The lender takes the loss, and the real number holder often never learns of it.
