Unlec – Free, detailed phone number lookup (unlec.com)

Is this US only?

I wonder where this data comes from? I was hoping I could search around for who returns

    "status",
    "spid",
    "total ported spid",
    "port date",
    "ratecenter",
    "state",
    "lata",
    "clli",
    "creation date",
    "fraud risk",
    "is textable",
    "lrn",
    "spid name",
    "ocn name",
    "ocn",
    "ocn type",
    "nn id",
    "nn description",
    "nn type",
    "cnam",
    "lnp history",
    "number"

But no dice.
