How to Use Fullz: Step by Step Without Wasting the File
A fullz is worth nothing sitting in a text file. It is worth something for about two hours after you buy it, and only if the profile, proxy and billing form are already prepared before you start the clock.
This is the order that keeps the file usable. Follow it exactly the first few times; it becomes automatic afterwards.

Before you buy
- Pick the target first. A target that actually asks for an SSN or a document. If it does not, you are overpaying.
- Check the target’s onboarding on a throwaway account. Note exactly which fields it asks for, in which order, and whether it does a document step.
- Prepare the profile: fresh anti-detect profile, timezone and language set to the target region, aged with a few minutes of browsing.
- Prepare the proxy in the file’s city. Confirm the exit IP geolocates where you expect before you buy anything.
Only then buy. Doing it the other way round wastes the drop window while you install a browser extension.
Filling it in
Copy, do not retype. Every field verbatim, including abbreviations, middle initials and odd line breaks. If the address has “Apt 3” stuffed into the street field, put it there too.
Order of application matters more than order of typing:
- Address and name first. These pass the card’s AVS check and are non-renewable. Get them right before anything else.
- DOB and SSN second, only on screens that ask. Each use spends a little of the file’s freshness.
- Document last, and only once. The upload is the highest-friction step.
Read billing address matching before your first attempt. Most fullz failures happen on the address, which is the cheapest field to get right.
Common mismatches that trigger review
| Proxy in a different state to the billing address | Manual review or straight decline |
| Timezone off by more than an hour | Challenge screen on the card |
| Legal name differs from embossed name | Document rejected |
| Address typed from memory of a similar one | AVS partial or full fail |
| Email domain mismatched to the age of the identity | Manual review on fintech |
Buy the file the same day you use it
ShadowSwipe lists files by drop date so you can buy inside the window rather than a week after it. $25 minimum, documents on a third of the stock.
After the target
A used file is not a dead file. The card is still chargeable on merchants that only want card and address, and the DOB still works on ordinary age-gated forms. What is spent is the SSN’s freshness and the document on that particular target.
Log the file with the target, the date and the result. Two weeks later, a file that failed one fintech may still be perfectly good on a telecom signup, and you will not remember which is which without the log.
What not to do
Do not buy three files at once to “have options”. They all age while you work through the first one. Buy one, use it, then buy the next.
Do not use the same profile across two fullz. The fingerprint links them and the second identity looks like an existing customer with new details. Fresh profile per file, always. See anti-detect browsers.
And do not submit a corrected form in a second tab. One submission, in one tab, and wait for the result. Document files covers the upload step when you reach it.
