- KYC (know your customer) is the set of checks an institution runs on a customer: identity, business, source of funds.
- Platform KYC (OnlyFans, MYM, Fansly) verifies the creator's identity and age before anything is published or paid out; the account must be in the creator's own name.
- Bank KYC is a legal anti-money-laundering duty, under the Bank Secrecy Act in the US and the Money Laundering Regulations 2017 in the UK, and it lasts for the whole relationship.
- A bank that cannot make sense of your activity or your inflows will freeze, question or close, and it is not allowed to tell you if it has filed a suspicious activity report.

KYC stands for know your customer: the checks an institution carries out on a person before and throughout the relationship, covering who they are, what they do and where their money comes from. The term covers both the identity verification OnlyFans and other platforms apply to creators and the anti-money-laundering checks banks are required to run.
Origin and meaning
KYC is banking compliance vocabulary. The statutes rarely use the acronym; they speak of customer identification, customer due diligence and ongoing monitoring. Applied to a company, the same exercise is called KYB, know your business: who runs it, who ultimately owns it, what it really does.
In everyday use, "doing your KYC" means uploading your documents; "KYC failed" or "KYC pending" means the institution has not yet accepted the file.
On OnlyFans and other platforms: creator KYC
No serious platform lets anyone publish adult content or receive earnings without verification. The usual sequence is a government ID, a selfie or biometric check, then bank and tax details. OnlyFans can ask for further age or identity verification at any time, and requires everyone who appears in content to be at least 18, with proof of identity and written, informed consent. MYM, the French platform, verifies each creator's age with an ID document and a selfie holding it.
Platform KYC does three jobs: confirming age and consent, paying the right person, and knowing sellers' identity and income for tax reporting. It has a direct consequence for agencies: the account belongs to the creator. OnlyFans states that its relationship is with the creator, not with any third party helping to run the account.
What the law says: bank KYC
United States. Under the Bank Secrecy Act, banks must run a customer identification programme to verify identity at account opening (31 U.S.C. § 5318(l)) and, for companies, identify the beneficial owners holding 25% or more under FinCEN's customer due diligence rule. They must monitor accounts and file suspicious activity reports, and they may not tell the customer a report has been filed (31 U.S.C. § 5318(g)).
United Kingdom. The Money Laundering Regulations 2017 require banks and payment firms to identify and verify customers, understand the purpose of the relationship, and monitor it on an ongoing basis. Disclosing a suspicious activity report in a way likely to prejudice an investigation is the offence of tipping off (section 333A of the Proceeds of Crime Act 2002).
For a creator, that means being able to show the activity is declared and to explain every platform payout: earnings statements, business registration, the agency contract if there is one. The documents to prepare are listed in our guide to KYC and source of funds.
Why a bank freezes or closes an account
- The file is incomplete. A refresh request went unanswered, and the bank cannot keep an account it cannot explain.
- The flows do not fit. Declaring $2,000 a month and receiving $15,000, or payouts from a platform you never mentioned, triggers enhanced review and sometimes a freeze.
- Suspicion. If a report has been filed, the bank will not say so, and an unexplained closure can follow.
In the UK, closure normally requires notice: for payment accounts opened on or after 28 April 2026, 90 days and a sufficiently specific explanation, with exceptions where financial crime is suspected. In the US, deposit agreements usually let the bank close at its discretion. What to do next is in our frozen account guide.
Mistakes to avoid
- Disguising the business. "Digital marketing" on the application, then OnlyFans payouts: that inconsistency is what gets files rejected.
- Routing a creator's earnings through someone else's account, a manager's or a partner's: the bank sees funds whose account holder is not the real beneficiary.
- Passing platform KYC in someone else's name. Platforms prohibit it, and OnlyFans can delete the account and treat earnings as forfeited.
