One question does most of the work
Ask who pays first. A legitimate domain marketplace makes its money from a commission when your name sells, so listing is free and the venue is paid out of a completed transaction. That alignment is the whole reason to trust it: the platform earns nothing unless you do. Anything that inverts it — a fee to list, a fee to be introduced to a buyer, a fee to release a payment already agreed — is asking you to pay for a promise rather than a result, and that is the shape almost every domain scam takes.
The upfront-fee broker
A real broker takes a commission on a completed sale, typically in the low double digits as a percentage, and takes nothing if the name does not sell. So an unsolicited approach from a broker who has a buyer ready and needs a few hundred dollars for an appraisal, a listing, or paperwork is the oldest pattern in this market. The buyer does not exist. Sometimes the same operation returns weeks later, apologising for the previous agent, offering to fix it for another fee. Legitimate brokers are paid out of the proceeds, and a broker asking for money before a sale has effectively told you what they are.
The appraisal that leads somewhere
A close relative. You are told your domain is worth an implausible amount, then told that realising it requires a paid certified appraisal, a listing package, or a marketing fee. The inflated figure is the bait and the fee is the product. The tell is not the number itself but the sequence: a genuine domain appraisal is information you can act on however you like, including doing nothing, and it does not come attached to a required next purchase from the same party.
Fake renewal notices
A long-running and entirely offline scam: a letter or email that looks like a renewal invoice for a domain you own, from a company that is not your registrar. Paying it either buys a worthless listing service or quietly transfers the name to them. Two defences, both simple. Know who your registrar actually is and renew only through them directly. And treat any renewal notice arriving by post as a marketing document, because your registrar has your email and will use it.
The buyer who is a little too keen
On the selling side, a buyer who offers well above your asking price, then requires something unusual to complete — a specific escrow service they will provide, payment by a method that cannot be reversed, or the name transferred ahead of funds — is running a variation on the same theme. The overpayment is there to make you reluctant to raise objections. A real buyer at a fair price who accepts standard escrow is worth considerably more than a generous one who does not.
How to check a marketplace in five minutes
Who owns it, stated plainly on the site, with a real company name and address. Whether the commission is published rather than quoted on request. Whether funds are held by a named escrow provider or a third party you recognise. How long the domain itself has been registered, which WHOIS will tell you. And whether people discuss it by name in places the company does not control, which is the difference between reviews and testimonials. A venue that fails several of these is not necessarily fraudulent, but it is unproven, and there is no reason to be the one proving it.
The venues that are simply real
The main aftermarket marketplaces and the established brokers are known quantities, publish their commission structures, and are discussed openly by people who use them. When a name is worth enough to be worth stealing, that is where to list it. The corollary is worth stating: the reason an unknown venue is offering you better terms is not usually that it has found an efficiency.
What a legitimate venue never asks for
Your registrar password or account login — a transfer needs an auth code, which is a different thing and is domain-specific. Your auth code before funds are confirmed held. A payment routed outside its own system. A fee to receive money that has already been agreed. Any one of these, from any party, regardless of how the conversation has gone up to that point, is where the conversation should end.
If you think you have been caught
Move quickly on the things that are still recoverable. Contact your payment provider about a reversal, because card and PayPal routes have real time limits. Change the password on your registrar account and enable two-factor authentication if a login was shared. Tell your registrar in writing if a transfer is in progress that you did not authorise. And report it, because these operations run on lists and the same approach is being made to other people this week.
- Legitimate marketplaces earn a commission on a completed sale, so listing is free.
- A broker asking for money before a sale has told you what they are.
- An inflated appraisal attached to a required next purchase is the appraisal scam.
- Renewal notices arriving by post from a company that is not your registrar are marketing at best.
- No legitimate party needs your registrar login, or your auth code before funds are held.
