KYC
Know Your Customer
Identification when opening an account: the bank checks the passport, address, origin of funds and purpose of the account. Required everywhere. The more complex the profile, the more documents needed. The first barrier everyone passes through.

In plain words
KYC (know your customer) is identification when opening an account or entering a programme. Put simply: the bank must understand exactly who you are, where you live, where your money comes from and why you need this account.
KYC is the first barrier everyone passes through. You will be asked for a passport, proof of address (usually a utility bill or a statement no older than 3 months), details of your profession and source of income, and the purpose of the account. The more complex the profile — several citizenships, business in different countries, PEP status — the more documents and questions. KYC is not one-off: the bank monitors continuously and periodically asks you to update your data.
In essence KYC is the front door, and AML the whole system behind it. Getting KYC right first time matters: confusion on the form or documents that do not match each other delay the opening by weeks.

Common mistakes
- Submitting documents in different languages without translation and apostille
- Bringing proof of address older than 3 months
- Stating one thing on the form and another in the documents
- Understating or concealing real turnover and the source of income
- Not confirming the particular bank’s requirements in advance
What this means for a BRIDGES client
BRIDGES GLOBAL prepares your KYC pack in advance for the particular bank: we tell you which documents will be accepted and in what form (translation, apostille, maximum age), and help you complete the form so that the data match and the account is opened first time.
Frequently asked questions
01 /How does KYC differ from AML?
KYC is the identification of a particular client on entry: who you are and where the money comes from. AML is the whole system of rules against money laundering, of which KYC is a part.
02 /Can documents be requested after the account is opened?
Yes. KYC continues afterwards: the bank monitors and periodically asks you to update your data or explain a large transaction.
03 /What proof of address is acceptable?
Usually a utility bill, a bank statement or a certificate no older than 3 months showing your name and address. We confirm the form requirements with the particular bank.
04 /Is a translation and apostille needed?
Often, yes: the bank asks for documents in another language to be translated and sometimes apostilled. We confirm the format in advance so that nothing has to be redone on the spot.
05 /How long does KYC take?
If the pack is assembled correctly — from a few days. Errors on the form or documents that do not match stretch the process out to weeks.
06 /Do crypto exchanges run KYC?
Yes. Large exchanges and payment systems also run KYC: they ask for an identity document, proof of address and sometimes the source of funds.
