Synthetic Identities Guide

Synthetic identity construction explained: how fabricated identities combine real and invented components into a credit file that did not exist before, how the file is aged, and where synthetic detection catches the pattern. Synthetic fraud is slow-burn - the timeline is the technique.

TL;DR - Build 6-18 months then harvest synchronized - patience is the whole technique.

COMPOSITION

Two construction classes:

Manipulated - real personal data altered: valid SSN with a fabricated name, borrowed address, invented history. The SSN anchors to a real credit file or opens one
Manufactured - components assembled from scratch: unissued SSN (invalid), name with no file, synthetic email and phone stack. Credit file built from zero
Piggyback layer - add authorized user tradelines from established accounts to bootstrap score history instantly

Material quality starts with the identity components themselves: SSN validity, name-address-phone coherence, email age (fullz field checklist defines what the base record must carry).

THE BUILD TIMELINE

Stage	Action	Elapsed
1 Seed	Secure card or secured card line against the new file	Day 0
2 Season	Small recurring charges, payments in full, no utilization spikes	Months 1-6
3 Expand	New tradelines, limit increases, AU additions	Months 6-18
4 Harvest	Stack credit lines across issuers inside the review window	Weeks
5 Bust-out	Max utilization at once, disappear	One cycle

The bust-out step is where all prior patience converts - every line drawn simultaneously before any single issuer''s alert propagates to the others.

WHERE SYNTHETICS GET CAUGHT

SSN-name mismatch against consortium records - the first hard filter at several major issuers
Thin-file plus high-limit requests - score curve and file age versus requested exposure
Address coherence - synthetic names on real addresses with no mail history
Phone behavior - brand-new VoIP number as primary contact, no porting history
Consortium synthetic models - shared markers (velocity of applications, shared fabricated components) propagate across lenders within weeks

Fraud teams run dedicated synthetic scores now - a file that looks constructed gets declined before utilization ever matters. The consortium feedback layer is exactly where construction patterns propagate between lenders.

OPERATIONAL NOTES

Component hygiene: one fabricated identity never touches another - shared addresses or phones link the whole set
Documentation layer: synthetic applications with plausible supporting artifacts (bank statements, mail-forwarded letters) clear manual review where bare applications die
Aging discipline: the temptation to harvest early kills files mid-build - under-seasoned bust-outs are the pattern most caught

Synthetic work punishes impatience - build slow, harvest synchronized, keep components isolated from every other identity in the portfolio.
