FlexCard
FlexCard is a virtual card for ads issued on Mastercard, rated 7.2/10 in our latest review. Below: what it costs and what it demands, the tiers the issuer publishes, and how the card cleared our live checkouts.
FlexCard is the strongest fit for ad spend and no KYC, and asks for no KYC at signup — we carry it at medium risk. Treat the fee rows as the deciding factor: a card that clears reliably but charges on every top-up costs more than its rating suggests.

Frequently asked
What does FlexCard cost to run?
The cost lines stack like this: issuing it costs from $2; there is no monthly fee on the entry tier; top-ups cost 3-4%; you need $50 to get going. Cash-out costs are what compound here, so weigh the recurring lines above the one-off fee.
Do I need to verify my identity for FlexCard?
FlexCard is a no-KYC card, so the account opens without an ID check. Cards in that tier decline more often at strict merchants, which is the trade-off you are taking.
How can I fund FlexCard?
You can fund it with crypto, bank transfer. Pick the one you can top up cheaply and repeatedly, because the load fee is charged every time.
Which billing address does FlexCard need?
Setting it up: cards are issued against US/UK/Brazil/Estonia/Spain/Denmark BINs. Copy the address the issuer generates rather than retyping it. A transposed digit is the most common reason a working range starts failing.
Does FlexCard work for subscriptions and AI tools?
We recorded successful charges for Meta and Google Ads. Where a card passes on one merchant and fails on another, the difference is usually the processor and the 3-D Secure setting rather than the card itself.
Will FlexCard trigger 3-D Secure?
Yes. FlexCard supports 3-D Secure, so expect a step-up prompt on larger or first-time charges. An OTP you can complete is fine; a challenge that never arrives is what kills the order, so keep the issuer app open at checkout.
How many cards can I open with FlexCard?
The issuer allows Unlimited. Multiple numbers under one account is the practical pattern here: one per merchant, so a single block does not take the rest of your billing down with it.
How VCCFinder tests
VCCFinder buys cards at retail and charges them on live checkouts, then publishes the clear rate and decline reasons next to each range. Where a card declined, the reason sits on its BIN page rather than in a footnote here.
