A bare Social Security number sells for roughly $1 to $4 on dark web marketplaces. That is the honest answer to how much your SSN is worth on the dark web, and it surprises almost everyone who hears it, because the number that costs a criminal less than a cup of coffee can be used to open credit lines, file fake tax returns, and rack up medical bills in your name. The price is low because supply is enormous. The damage is high because one working number is all a fraudster needs.
The Price Range for a Stolen SSN
Anonymous marketplaces on the dark web trade personal data the same way other markets trade commodities. A Social Security number by itself, with no supporting information attached, typically sells for a few dollars at most. Years of large-scale breaches at corporations and government agencies have pushed hundreds of millions of records onto these markets, and the oversupply keeps individual prices near the floor. Buyers at that price are essentially purchasing lottery tickets, grabbing numbers in bulk and hoping some fraction turn out to be active and unmonitored.
Prices climb sharply when the number arrives with context. Sellers package SSNs into profiles called “Fullz” that pair the number with the victim’s full name, date of birth, address, phone number, and sometimes bank login credentials or credit card details. A basic Fullz package runs about $30 to $100. One built around a high credit score, active financial accounts, or verified employment history can sell for several hundred dollars. The SSN is the key; the surrounding data determines which doors it opens.
Why Some Numbers Sell for More
Not every number carries the same tag. A few factors move the price.
Strong Credit and Linked Accounts
An SSN attached to a high credit score is worth more because it unlocks higher credit limits and larger loans immediately. A number tied to an existing bank account with working login credentials is more valuable still, because the buyer skips the slow work of building a fraudulent credit profile from scratch.
Children’s Numbers
A child’s SSN commands a premium precisely because nothing has ever been done with it. There’s no credit history to trip a fraud alert, and parents rarely check a child’s credit file. A criminal can build a fabricated credit identity around that number and use it for years before anyone notices. Javelin Strategy & Research found that roughly one in 50 children in the U.S. have been victims of identity fraud. Placing a credit freeze on a child’s file with each of the three bureaus is the standard countermeasure.
Deceased Individuals
Numbers belonging to people who have died are targeted for what fraudsters call “ghosting.” No one is monitoring credit reports or filing tax returns under the number, so the fraud can run for years. The Social Security Administration’s Death Master File is meant to flag these numbers, but reporting gaps leave a window criminals exploit.
What Buyers Actually Do With Your Number
The price a criminal pays is not the point. The point is what they build with the number, and the schemes range from crude to elaborate.
Synthetic Identity Fraud
A real SSN gets paired with a fabricated name, birth date, and address to create a person who does not exist. The first credit application usually gets denied, but the denial itself opens a credit file. From there, the invented person builds a payment history with small accounts over months, then maxes out every available line and vanishes. Lenders lost an estimated $3.3 billion to synthetic identity fraud on open credit accounts by the end of 2024. Because the identity is not quite yours, the fraud often goes undetected for months or years. The real SSN holder usually finds out only when a collector calls about accounts they never opened.
Tax Refund Fraud
Criminals file a fake return early in the season and claim the refund before the real taxpayer submits. When the legitimate return arrives, the IRS rejects it as a duplicate. Untangling the mess takes months and requires an Identity Theft Affidavit with the IRS.1Internal Revenue Service. When to File an Identity Theft Affidavit
Employment Fraud
Someone working under your SSN causes W-2 wages to be reported to the IRS under your name. The first sign is often a CP2000 notice claiming you underreported income. The IRS advises against adding that phantom income to your return or filing an amended return. Instead, call the IRS at the number on the notice and report the situation to the Social Security Administration so your earnings record can be corrected.2Internal Revenue Service. Employment-Related Identity Theft
Medical Identity Theft
A stolen SSN combined with insurance details lets a criminal receive care, fill prescriptions, or bill procedures under your identity. The financial mess is bad enough, but the medical file is worse. Their information gets mixed into your records, possibly including a different blood type, different allergies, or conditions you don’t have. In an emergency, a doctor reading a contaminated file could prescribe the wrong treatment. Cleaning corrupted medical records means working through hospitals, insurers, and providers with no single point of contact.
What It Costs You
The buyer pays a few dollars. You pay with time, credit, and sometimes safety. Financial losses vary by scheme, but the time cost lands almost the same on everyone. Victims commonly spend dozens of hours on the phone with credit bureaus, banks, the IRS, and law enforcement, disputing accounts and correcting records. Federal law allows courts to order convicted identity thieves to reimburse victims for that time, but restitution requires a conviction, and many cases never reach one.3Office of the Law Revision Counsel. 18 USC 3663 – Order of Restitution
Credit damage compounds everything. Fraudulent accounts and missed payments drag your score down, which can raise your interest rates on legitimate loans, disqualify you from renting, or cost you a job. Rebuilding after identity theft is measured in months and years, not days.
What to Do If Your SSN Has Been Exposed
If your number has been part of a breach or you suspect it is being used, a few steps limit the damage. Speed matters, because most of these protections work best before a criminal has time to open accounts.
Freeze Your Credit
A credit freeze blocks lenders from pulling your report, which stops most new-account fraud outright. Freezes are free under federal law at Equifax, Experian, and TransUnion, and you can lift a freeze temporarily when you apply for credit yourself. A freeze does not affect your credit score or your existing accounts.4Federal Trade Commission. Credit Freezes and Fraud Alerts
A fraud alert is a lighter option. An initial alert lasts one year and requires lenders to verify your identity before extending credit. You only need to contact one bureau; it must notify the other two.4Federal Trade Commission. Credit Freezes and Fraud Alerts
Check Your Credit Reports
Federal law entitles you to a free report from each of the three bureaus every 12 months through AnnualCreditReport.com, and all three now offer free weekly reports through the same site. Regular checks are the fastest way to catch accounts or inquiries you did not authorize.5Federal Trade Commission. Free Credit Reports
Get an IRS Identity Protection PIN
An Identity Protection PIN is a six-digit number the IRS assigns you that must appear on your return for it to be accepted. Without it, a fake return filed under your SSN is rejected automatically. Anyone with an SSN or ITIN can enroll through their IRS online account. If you cannot create an online account and your adjusted gross income is below $84,000 (or $168,000 for married filing jointly), you can apply using Form 15227. Parents can request an IP PIN for dependents as well.6Internal Revenue Service. Get an Identity Protection PIN
Report the Theft
Where to report depends on how the number is being misused:
- For general identity theft, file at IdentityTheft.gov. The FTC site generates a personalized recovery plan with pre-filled letters for creditors, collectors, and bureaus.
- If someone is working or claiming benefits under your SSN, report it to the Social Security Administration’s Office of the Inspector General at 1-800-269-0271 or through oig.ssa.gov.7Social Security Administration. Fraud Prevention and Reporting
- For tax-related identity theft, file IRS Form 14039 (Identity Theft Affidavit) and request an IP PIN.1Internal Revenue Service. When to File an Identity Theft Affidavit
None of these steps undo a breach. They narrow what a criminal can do with a number that cost them a few dollars.
