Why the checks exist
Financial institutions are required to know who their customers are. Those obligations sit under anti-money-laundering and counter-terrorist-financing rules, and they apply whether or not the institution would otherwise ask.
That accounts for behaviour which otherwise looks arbitrary: being asked for a document you have already given another institution, being asked what a large deposit is for, and being declined without a reason. Where a decision rests on financial-crime controls, staff are often barred from explaining it — frustrating, but not evasive.
The stages
- Application
Personal details, address history, and sometimes employment and income. Accuracy matters more than completeness — mismatches against records are a common cause of referral.
- Identity verification
Often electronic, checking your details against credit and public records. If that fails — commonly for people new to a country or with little credit history — documents are requested instead.
- Screening
Checks against sanctions and politically-exposed-person lists. A name match can trigger a manual review even when it is not you.
- Decision
Approval, a request for more information, or a decline. Timescales vary from minutes to weeks depending on which path it takes.
- Funding and activation
An opening deposit where required, then access credentials. Some features are restricted until the first deposit clears.
Electronic verification relies on records existing. Someone who has recently moved country, has never borrowed, or is not on an electoral register may fail an automated check while being an entirely straightforward customer. The remedy is document-based verification, not a different institution.
Documents required
| Category | Typically accepted |
|---|---|
| Proof of identity | Passport, national identity card or photocard driving license. Must be current, and the name should match the application exactly. |
| Proof of address | A recent utility bill, bank statement, tax notice or tenancy agreement showing your name and address. Institutions set their own limit on how old it can be, and usually want the whole document rather than a cropped page. |
| Proof of income | Payslips, tax returns or business accounts, for accounts with income conditions or for any credit application. |
| Tax residency | Tax identification numbers for each jurisdiction where you are resident, under international reporting rules. |
| Source of funds | For large deposits, evidence of where the money came from — a property sale, an inheritance, a business disposal. Being asked is routine, not an accusation. |
Upload identity documents only through an institution's own channel, reached by typing the address yourself. A request for them by email or messaging app is a standard identity-theft technique: those documents are precisely what is needed to open accounts in your name.
If an application is declined
- You may not be told why. Where a decision relates to financial-crime controls, the institution is often legally barred from explaining it.
- Check your credit file first. Errors and outdated addresses are a frequent cause, and you are generally entitled to see the file and have mistakes corrected.
- Check your address records. Electoral registration and a consistent address history markedly improve automated verification in many countries.
- Ask about basic accounts. Many jurisdictions require banks to offer a basic account to eligible applicants who cannot access a standard one.
- Avoid rapid reapplication elsewhere. Multiple applications in a short window can themselves count against you.
Frequently asked questions
Why do banks ask where my money came from?
Source-of-funds checks are a legal requirement on larger or unusual deposits. Being asked is routine and does not imply suspicion of you specifically.
How long does opening an account take?
It ranges from minutes, where electronic verification succeeds, to several weeks where documents or manual review are required. The variable is verification, not the product.
Can I be refused without a reason?
Yes. Institutions can decline to offer a service, and where the decision involves financial-crime controls they are frequently prohibited from explaining it.
Does being asked for more documents mean something is wrong?
Usually not. An electronic check that cannot find enough records — common after a recent move, or for anyone who has never borrowed — falls back to documents. It is a different route to the same decision, not a worse one.
