The gap this fills
Formal screening — credit checks, identity verification, tenant referencing — costs $25–60 a time and takes days. So for most small operators it only happens at the end, if at all. Meanwhile the cheapest, fastest fraud signal available is sitting in the first message they sent you: the email address. An address created last week, on a domain registered last month, with no visible history, is not the address of the established professional they claim to be. This check reads those signals in seconds, before you spend real money screening someone who was never real.
Who uses it
- Car hire and equipment rental. The deposit doesn't cover the asset. Check the renter's address before the booking is confirmed — a throwaway or days-old address on a high-value booking is the single clearest stop sign available.
- Private lending. Before the formal affordability work, a $5 check answers the cheaper question first: is this person's contact detail even real? An established address with linked identity is consistent with a real borrower; a fresh one warrants harder questions before paperwork.
- Letting — in both directions. A landlord can sanity-check an applicant's address before paying for referencing. A renter can check the "landlord" asking for a holding deposit — fake-landlord scams run on young addresses and freshly registered domains, and the check exposes both.
- High-risk orders. An unusually large order from a new customer is the classic chargeback setup. Checking the buyer's email — age, disposable domain, identity — is the manual review step fraud teams recommend, automated into one pass.
The report is the point
Every $5 report is a dated PDF with a unique Report ID: the address's visible history, domain registration record, mail configuration, identity signals and an overall verdict, as they stood on the day of the check. File it with the booking, the loan application or the order. It's contemporaneous evidence of the check you ran — the kind of artifact that makes an insurer, an accountant or a partner take the rest of your process seriously.
Where it sits in your process
First pass, not final word. A clean email check doesn't replace referencing, identity verification or credit checks where the decision needs them — it tells you whether the counterparty is worth the cost of those checks at all, and it catches the obvious fakes that formal screening is too slow and too expensive to catch at the top of the funnel.
What this is not
Not a consumer report. Check Email Age is not a consumer reporting agency, and its reports are not consumer reports under the US Fair Credit Reporting Act or equivalent laws elsewhere. Do not use it to decide anyone's eligibility for credit, insurance, housing or employment. It is a fraud signal on an email address — a supplement to your own judgement and to formal screening, never a substitute where the law requires one. Details in the terms.
