Google Ads refuses prepaid cards on one payment setting, and says so in one line of its own help page: “Google does not accept prepaid cards for postpay.” (Google Ads Help, “About payment methods for Google Ads”, read on 26 September 2026). According to Blomo’s data as of 26 September 2026, only one of the six Blomo cards — the Estonia card — is registered as prepaid; the Netherlands, Spain, Poland, United Kingdom and Indonesia cards are not. A card’s BIN classification can change. Google’s rule catches the Estonia card on postpay, and the other setting, prepay, is not offered in most of Europe. For no card does anyone — Blomo included — promise that Google will accept it.
The rest of this article is the detail behind that paragraph: what the two settings are, what Google’s page actually says, and what a Blomo balance has to look like on the day Google charges it.
Postpay and prepay are two different ways of being charged
Google Ads has more than one payment setting, and the rule about prepaid cards is attached to one of them. In Google’s own words, a card can be used on “postpay (you’re automatically charged after your ads run) and prepay (you add funds into your account before your ads run)” (same page, same date).
| Setting | Who starts the charge | When | What Google’s page says about prepaid cards |
|---|---|---|---|
| Postpay | Google, automatically | After the ads have run | “Google does not accept prepaid cards for postpay.” |
| Prepay | You, by making a payment | Before the ads run | No such note — and prepay is not available everywhere |
Two cautions about the second row, because it is the one people over-read:
- Google’s page restricts prepaid cards on postpay. It does not say, anywhere we could find, that prepaid cards are accepted on prepay. The absence of a rule is not a promise, and Google can still decline a card for reasons it does not publish.
- Prepay is not available in most of Europe. The same page carries a list headed “Countries and territories where prepay isn’t available”. In the version we read on 26 September 2026, its Europe section includes, among others, Estonia, the Netherlands, Poland, Spain, the United Kingdom, Germany, France and Italy. Google also says that the methods on offer “depend on your currency and country selection, and sometimes also your payment settings”, and points to its own payment options tool for the exact answer for your account’s country.
What Google’s page says about cards, word for word
The page is split by country — the reader chooses one from a drop-down — and the card sections differ slightly between versions. These sentences appear in the versions we read on 26 September 2026:
- “Note: Google does not accept prepaid cards for postpay.”
- “In addition to certain types of credit cards, we also accept debit cards with the Visa or MasterCard logo.”
- “Some payment methods can’t be used with currencies other than your country’s official currency.”
Google’s page describes the card types it takes as credit and debit. It does not name Blomo, and nothing on it tells you in advance how Google will classify a particular card number. That classification is made from the card’s BIN, the leading digits of the number — the mechanism is laid out in what a BIN is and why a shop declines your card.
How each Blomo card is registered
| Card | Registered as prepaid | Transaction fee | Monthly spending limit | Minimum balance to issue |
|---|---|---|---|---|
| Netherlands · Visa · EUR | No | 0.5% | 100,000 USDT | 1,000 USDT |
| Spain · Visa · EUR | No | 1% | 100,000 USDT | 500 USDT |
| Poland · Mastercard · PLN | No | 1% | 50,000 USDT | 300 USDT |
| United Kingdom · Visa · GBP | No | 1.5% | 50,000 USDT | 250 USDT |
| Indonesia · Mastercard · IDR | No | 1% | 30,000 USDT | 200 USDT |
| Estonia · Visa · EUR | Yes | 1% | 5,000 USDT | 100 USDT |
The “registered as prepaid” column is Blomo’s data as of 26 September 2026; a card’s BIN classification can change. Fees, limits and thresholds are from the Blomo fees page, which is the live source.
What the table does and does not tell you:
- The Estonia card falls under Google’s postpay rule. Google’s page says so in as many words about prepaid cards, and the Estonia card is registered as prepaid.
- The other five are not caught by that one rule — and that is all. Google does not publish its full acceptance logic, and Blomo does not promise that Google Ads, or any other merchant, will accept a particular card.
- Currency. A charge in the card’s own currency spares you a second conversion at the merchant’s or the network’s side; the amount taken off your USDT balance still follows the rate of that currency. Google also notes that some payment methods cannot be used with currencies other than your country’s official currency.
- The monthly ceiling. The Estonia card’s ceiling is 5,000 USDT a month; the other five run from 30,000 to 100,000 USDT. The ceiling covers everything the card pays that month, not only ads.
What the balance has to look like on postpay
On postpay the charge is started by Google, not by you. Nothing is typed at a checkout; Google charges the stored card when its own billing says so. For a card funded from a balance, that makes the balance on the day of the charge the whole question. A charge that finds too little on the balance fails like any other card payment. What Google then does with the account is Google’s rule, and it is not covered here.
Two numbers shape the headroom:
- The card’s transaction fee is added to every charge: 0.5% to 1.5% depending on the card (fees).
- The minimum top-up is 50 USDT, and the top-up fee is 1% added on top of the amount you ask to have credited.
And one Blomo action empties the spendable balance without any money leaving it: ordering a new card holds your whole available balance until that card is activated. A Google charge that arrives while the hold lasts finds nothing to draw on. A top-up made after the order is not held. The timing is covered in ordering a second card holds your balance.
On prepay, the first payment can be a dollar short
On the prepay setting Google describes a card check in plain numbers: “In some cases, Google Ads may test a small charge on your card to make sure it’s valid. You won’t actually pay that test amount, but the amount of your payment will be reduced by it. For example, if you decide to charge $300 USD to your card, Google Ads may make a test charge of $1 USD and your card will be charged $299 USD to run ads.” The same page, in its section on one-time-use cards, adds: “Be sure to include $1 USD more than your payment amount for card verification.” (Google Ads Help, read on 26 September 2026.)
In Google’s example the dollar is counted towards your payment rather than handed back. What happens to a check amount that a service does not count towards a payment is covered in why was I charged $1 when adding my card?
3-D Secure
Google may ask for 3-D Secure confirmation when the card is added or a payment is made. Blomo cards support 3-D Secure, and the confirmation request appears in the Blomo app and in the Blomo Telegram bot. Confirm it there while the Google page is still open.
Questions people actually ask
Does Google Ads accept prepaid cards?
Not on postpay. Google’s help page says: “Google does not accept prepaid cards for postpay.” The page carries no such note for prepay, but prepay is not available in most of Europe, and Google does not promise acceptance of any particular card.
Which Blomo card is prepaid?
According to Blomo’s data as of 26 September 2026, only the Estonia card is registered as prepaid; the Netherlands, Spain, Poland, United Kingdom and Indonesia cards are not. A card’s BIN classification can change.
Does Google’s prepaid rule apply to the Estonia card?
Yes, on postpay: the Estonia card is registered as prepaid, and Google does not accept prepaid cards for postpay. Prepay is not offered in most European countries — Estonia itself is on Google’s list — so check Google’s payment options tool for your account’s country.
Why was a dollar taken when I paid Google Ads?
On prepay, Google may make a test charge of $1 USD to check the card, and counts it towards your payment rather than charging it on top. Google’s own example: a $300 payment becomes a $1 test charge and $299 for ads.
Will Blomo guarantee that Google accepts my card?
No. The decision is Google’s and is made from the card number before the balance is consulted. Blomo states how each card is registered; it does not promise acceptance anywhere.
