If you went to Equifax right now and set up an account, they’d walk you thru numerous questions like...
Out of the 4 addresses below, is one of them your current address? They’d list 4 addresses and one WILL BE yours. They’d do the same question but with the address you lived at as a kid. And one of the addresses will be your old address. Then they’d give you four companies and ask you to ID the one you worked at from the period of this to that. And one would be the company you worked at.
The same thing would happen if it were the other two credit bureaus. They know everything.
That sounds like LexisNexis.
