Trading platforms like eToro and Trading 212 need your national insurance number when you open an account to help identify you and reduce the risk of money laundering.
If you’ve recently received a communication from your broker asking for your National Insurance number and still want to trade with them, best thing to do is just provide it as soon as possible and put it down to the FCA’s regulatory requirements.
Which, whilst annoying are in the best interests of clients and brokers.Β The rules are there to ensure clients are treated fairly and London maintains it status as the financial centre of the universe.Β Security and due diligence are the corner stone of modern financial services business.
However, a lot of UK financial professionals are getting a bit fed up with this and are setting up online trading platform offices in Dubai. Fair enough, the weather is nicer…
But why are brokers asking for national insurance numbers now?
It’s not like they don’t already have your ID? At 2017’s Finance Magnates London Summit, Natalia Hunik, Global Head of Sales gave an excellent talk on marketing in the Forex industry, and one thing that was covered was how much Plus 500 spent on marketing. Compared to other brokers it was a hefty 30% of revenue (see featured image). Clearly onboarding a huge amount of clients.
To reduce the onboarding costs and time, they only asked for the minimum amount of information required by the FCA. Sure enough, in order to complete, all the other forex brokersΒ followed suit.
It’s not a strategy that overly pays off in the long run, because the easier it is to open an account the overall quality of client goes down. i.e. lots of small clients meaning not enough time to look after the big ones.
Anyway, as part of the process, clients could scan a copy of their passport, drivers licence, payslip etc, which satisfied the regulators at the time. It also meant that in some cases your CFD brokerΒ does actually have your national insurance number and passport number, but as a digital scan, rather than inputted in numbers.
So, if you’re asked for additional information from your spread betting brokers, just get on an give it. It’s the rules and if you delay too long will mean that you will eventually be blocked from trading unless your account is fully compliant. It literally takes less than one minute.
Make sure you are trading with a decent regulated broker
Here’s how to make sure your broker is what we would class as good…
- Are they regulated by the FCA (check here)
- Are they in our comparison tables?
- Don’t trade with a broker that is based offshore or you won’t get FSCS client money protection
- Never be pressured into trading or take advice on high-risk trades from anyone who is not regulated to do so.
- Always do your own research before depositing money with a broker
- Never trade speculative products with money you can’t afford to lose.
