I haven't used Brazilian banks, but I've experienced similar acceptance problems with virtual cards from Europe. It definitely isn't limited to one region.
 
One thing I'd recommend is checking community discussions every few months because providers that work today may stop working after policy updates.
 
If you're spending a decent amount on Google Ads each month, it may be worth opening a dedicated business banking account specifically for advertising expenses.
 
I've been following discussions like this because payment reliability has become almost as important as campaign optimisation. Looking forward to seeing more recommendations.
 
Hopefully members with long-term Google Ads experience can share what's currently working. The landscape changes so quickly that advice from even six months ago may already be outdated.
 
I went through exactly the same situation a few months ago. I was relying on a virtual card provider that worked well initially, but once I started scaling my campaigns, the limits became a real problem. Creating only a handful of cards each week just isn't enough when you're managing multiple ad accounts. Eventually, I switched to a business banking solution, and while it wasn't perfect, it was much more reliable. I'm interested to see what other members are using these days because things change so quickly.
 
From my experience, the BIN plays a much bigger role than most people realise. I've had cards from the same provider where one BIN worked perfectly and another was declined immediately. It can be very frustrating because you never really know what you're going to get. If anyone has found a provider with consistently accepted BINs, I'd definitely like to hear about it.
 
I've used Wise for business payments, and while it's a great platform overall, my experience with Google Ads has been mixed. Some cards were accepted without any issues, while others required additional verification or failed during billing. I don't think there's a perfect solution anymore, but I'd also appreciate hearing what has been working for other advertisers recently.
 
One thing I've learned after managing Google Ads for several clients is that stability matters more than constantly generating new cards. Google seems to favour accounts with consistent payment histories. If you're able to keep the same payment method active for longer periods, you may experience fewer billing problems over time.
 
I tried several virtual card services last year because I thought they would make campaign management easier. Unfortunately, many of them stopped working after a while or introduced stricter limits. Nowadays, I keep a couple of backup payment methods available so I'm not completely dependent on a single provider.
 
I've noticed the same verification charges you're talking about. Sometimes a card works immediately, while other times there's an unexpected authorisation charge before everything starts working normally. It's difficult to know whether the issue comes from Google, the issuing bank, or the payment processor.
 
Nubank worked really well for me in the past, but my recent experience hasn't been nearly as good. I don't know if their BIN ranges changed or if Google updated its payment risk checks, but acceptance rates definitely seem lower than they used to be.
 
Before changing providers, I'd also review your Google Ads account setup. Billing country, account age, payment profile, and campaign history can all influence whether a payment method is accepted. Sometimes the card isn't actually the problem.
 
I've been looking for a provider without daily or weekly card limits for quite some time. Most of the services I found either limit the number of cards or charge fairly high fees once you exceed a certain threshold. Hopefully someone here has found a better alternative.
 
Personally, I'd rather pay a small monthly fee for a reliable service than constantly waste time searching for new cards that may or may not work. Time spent dealing with payment issues is often more expensive than the service itself.
 
Something I've observed is that virtual cards often work well initially, but their success rate gradually drops over time. Whether that's because of Google updating its fraud detection or changes by the issuer, I'm not sure. Either way, it's becoming increasingly difficult to find long-term solutions.
 
This is a really useful discussion because payment methods are something many advertisers don't openly talk about. Everyone focuses on keywords and campaign optimisation, but reliable billing is just as important if you want your campaigns running smoothly.
 
I mainly manage campaigns for small businesses, so I don't need dozens of cards every week. Even so, I've still experienced random declines with perfectly valid cards. That tells me Google's payment system evaluates much more than simply whether a card has available funds.
 
Have you considered opening a dedicated business account specifically for advertising expenses? It may not generate unlimited virtual cards, but having a stable financial profile has reduced my payment issues significantly over the past year.
