DataX
An Equifax-owned subprime bureau, often paired with Teletrack, that tribal lenders check.
What "datax" means
DataX is a specialty credit-reporting agency owned by Equifax and focused on alternative and short-term lending data. Because Equifax owns both DataX and Teletrack, a lender that says it "doesn't use Teletrack" may simply pull DataX instead — the same company, a different file.
That overlap is the catch behind "no Teletrack" marketing: skipping one specialty bureau rarely means no check at all. You can request your DataX file directly, as with any consumer bureau.
