You thought opening a trading account would take just a few clicks, an email address and a password? Then your broker asks you for proof of identity, proof of address and a few details about your finances…
Don’t panic: this is a normal step. Brokers have to verify certain information before accepting you as a client. The easiest approach is to prepare your documents from the outset: you’ll avoid having to resend documents and the endless back-and-forth with customer support.

Why is your broker asking for all these documents? KYC explained
Brokers are required to verify their clients’ identity. Behind this obligation is an acronym you will come across frequently: KYC, meaning Know Your Customer. The principle is fairly straightforward: the broker must know who they are opening an account for. These checks form part of the fight against money laundering (AML), terrorist financing and fraud. They are also used to gather the information needed to assess your knowledge and experience of financial products.
In practice, the broker mainly wants to know who you are, where you live and, in some cases, where the money you intend to deposit comes from. They may also ask whether you have invested in the stock market before and which products you are familiar with. This isn’t paperwork for paperwork’s sake: these checks are required by regulation and help ensure the account-opening process is properly supervised.
Good news: today, part of these checks can be completed entirely online. The broker may ask you to photograph your identity document, then take a selfie to confirm that you are the person shown on it. It’s fairly convenient… unless the photo is blurry or glare obscures the information. In that case, your documents may need to be reviewed manually.
💡 Did you know?
You and a friend may both open an account with the same broker without receiving exactly the same list of documents. Why? Because checks can vary depending on your country of residence, the type of account, the amount deposited or the broker’s own internal controls. So there’s no need to worry if someone else wasn’t asked to provide the same document as you.
The documents you need to provide to open a trading account
Let’s get practical: what should you prepare before you begin? In most cases, the four categories below are required. Depending on your situation, the broker may ask for slightly less… or a few additional supporting documents. In all cases, rely on the list shown during your registration.
#1 - A valid identity document
This is often the first document requested: an official photo ID to confirm your identity and age. A passport and driving licence are the most common options. Some brokers also accept a national identity card, but it’s best to check before sending it.
A small tip that can save you time: place the document flat in a well-lit area and make sure all four corners are visible in the photo. If both the front and back are required, don’t forget the reverse side. Glare over your date of birth or a cropped image can be enough for an otherwise valid document to be rejected. The document must also be in date; as for the minimum age, that depends on the rules applicable to the account and the country concerned.
#2 - Recent proof of address
The broker must also confirm your address. They may ask for a gas, electricity, water or council tax bill, a bank statement or a tax notice (such as a P60 or self-assessment tax letter). A tenancy agreement or mortgage statement may also be accepted depending on the provider.
The document generally needs to be recent, often less than three months old, and must clearly show your name and address. Be careful: a mobile phone bill or insurance certificate isn’t accepted by every broker. Before sending the first document you come across, take a few seconds to check their official list.
And what if you live with your parents or with someone else, and have no bills in your name? That isn’t necessarily a problem. Some brokers accept a letter confirming your accommodation, together with additional supporting documents. The right approach is to check their instructions before sending multiple documents.
#3 - A bank statement and, in some cases, proof of source of funds
Depending on the platform and your situation, you may be asked for information about your employment, income or the amounts you intend to deposit. A bank statement can be used to verify the details of the account used for transfers. In some cases, particularly where a deposit is large or additional checks are required, the broker may also ask for proof of source of funds: proof of income (such as a payslip or P60), a savings-related document or another document suited to your circumstances.
The distinction matters: showing that a bank account is in your name doesn’t automatically prove where the money in it comes from. For example, a statement can confirm that you’re the account holder, while a payslip or a savings-related document can help explain the origin of the funds.
⚠️ One more point to bear in mind: if you plan to make a transfer from a friend’s or relative’s account, be careful. Many brokers don’t accept third-party deposits.
#4 - Information about your trading experience
Have you bought shares before? Used ETFs? Or are you only just discovering how the markets work? The broker may ask you these questions, along with others about your knowledge of financial products and your personal circumstances.
You don’t need to revise as if you were sitting an exam. The aim isn’t to catch you out, but rather to check whether you understand the risks of the products you’re considering using. Access to certain complex or particularly risky instruments may be restricted depending on your profile and the rules that apply. So answer honestly: it’s better to say you’re a beginner than to claim you understand a product you’re not yet familiar with.
| Document or information | Examples | What to check |
| Identity | Passport, driving licence, sometimes national identity card | Validity, legibility, front and back if required |
| Address | Utility bill, bank statement, council tax bill, tax notice | Name, address and document date |
| Banking information | Bank statement, account details | Account in the holder’s name |
| Source of funds | Proof of income (payslip, P60) or other evidence, if requested | Requirement varies depending on the case |
| Experience | Questionnaire on knowledge and products | Accurate and consistent answers |
Mistakes to avoid
Have you prepared everything? Perfect. But before clicking "Send", take two minutes to review your documents. Some small mistakes are enough to delay the opening of an account:
- Using a nickname or a different name from the one shown on your identity document. Even a change in the order of names may require verification.
- Sending expired, blurry or incomplete documents: cropped photo, proof of address that’s too old, missing reverse side…
- Providing non-compliant proof of address, for example in a third party’s name without any additional documents that may be required.
- Making a transfer from an account that isn’t yours, where the broker requires a bank account in the holder’s name.
- Completing the experience questionnaire carelessly: contradictory answers can lead to requests for clarification or restrict access to certain products.
What happens after you send the documents?
You’ve sent your documents: what next? The broker won’t necessarily approve everything with a single click. Here’s what usually happens behind the scenes:
- Initial check: the system reviews the documents and the information provided.
- Additional review if needed: a team may look into a document that’s difficult to read or information that appears inconsistent.
- Approval or request for a new document: the broker tells you whether the documents are complete or what needs to be corrected.
- Account activation: once the account opening is confirmed, you can usually proceed with funding the account in line with the applicable arrangements.
How long does it take? Sometimes everything is completed the same day. In other cases, especially if a document is illegible or needs to be replaced, it may take several working days. There’s no single timeframe guaranteed by all brokers. If you need your account ready by a specific date, it’s best not to leave it until the last minute.
What about business accounts or non-residents?
Would you like to open the account in a company’s name? You’ll generally need a few extra documents: proof of registration (such as a Certificate of Incorporation), articles of association, identification for the representatives or information about the people who control the company. Do you live abroad? The broker may also ask for documents relating to your residence or tax situation. These cases are a little more specific, so the best option is to check the provider’s conditions directly.
Key points before you begin
- Prepare a valid identity document and recent proof of address.
- Check the exact list of documents accepted by your broker.
- Send documents that are complete, legible and consistent with one another.
- Answer honestly to questions about your experience and finances.
Ultimately, opening a trading account isn’t especially complicated: the main thing is knowing which documents to prepare and taking the time to send them correctly. A well-photographed identity card, a recent supporting document and consistent information can save you a good deal of back-and-forth. And if a particular document is causing an issue, don’t hesitate to ask customer support exactly what’s required: it’s often quicker than trying your luck three times with the same document.
