@SheikhOvais,
May I answer your question in parts ?
a) Every marketplace or company that operates an escrow service or handles client money in the EU, must since 13th January 2018 be Government registered under EU law. Similar laws probably operate elsewhere around the world.
And any such Government regulated company must both identify and verify their customers under anti-money laundering and counter terrorist financing laws.
b) So if you are dealing with a company that provides escrow and it does not both identify you and verify your identity, then that company is probably breaking the law by remitting money whilst not Government regulated.
c) How a company identifies and verifies its customers varies from company to company.
At Transpact.com, we often identify and verify our customers without them ever realising they have done so, and without them requiring extra steps to do so.
As cumulative payment sizes increase, or if other risk factors indicate, or even due to arbitrary random selection (random sampling is required by law), extra evidence of identity may sometimes be required from a customer. That is broadly the law across the world, in all jurisdictions.
d) A few minority players in the domain world have abused the system and used domain transfers for significant money laundering.
(The definition of Money laundering in the EU has included for the last year the movement of money that has not been properly taxed, and this has exacerbated the problem).
So whilst the majority of those transferring domains do so entirely properly and without issue, the acts of the minority have meant that any escrow service (or client money handling service) has to perform checks to ensure that any one transaction is not a case of money laundering or terrorist financing (the assassination of Hamas's Mahmoud Al-Mabhouh is just one case where the terrorist funding for the terrorist event clearly occurred through an escrow service).
e) So it is unlikely that we will ever go back to a world where you can use an escrow service without having to provide evidence of your identity.
That means that when using an escrow service, you have to worry about identity theft and the escrow service getting hacked and sharing your personal documents.
That is actually a good reason to choose an EU authorised payment firm because of two key EU laws:
i) EU law from 13th January 2018 demands that any payment firm cannot be authorised unless it has performed a complete information and IT security lockdown and investigation, and ensured that it cannot be hacked, and thereafter requires an annual audit to ensure that this remains so (as well as a lot of other constant vigilance measures), and
ii) EU law has introduced GDPR, that states that if a firm is hacked and loses its customers information, it can be fined up to €20 million or 4% of its worldwide turnover (whichever is greater !).
So an EU authorised payment firm offers you a fairly reasonable guarantee that your personal infromation will be kept confidential and secure.
f) At Transpact.com, a transaction cannot become 'Live & Protected' if any customer verification is outstanding. That means, if we ever ask for evidence of identity (and often we do not), then you can always cancel the transaction and take back your payment if you wish, as the escrow transaction will not have commenced yet.
I think this has happened to us just once in almost nine years of trading.
g) In answer to your second question, being in the USA does not rule you out of a transaction with us. But remember, you will be transacting in the UK under UK and EU law. But this offers very, very substantial protection (and probably more protection than your local law).
Sorry for the long diatribe.
