Running costs
The first charge carries no issuance fee. Every charge after it carries no top-up fee, and outside USD, no FX markup. The fee table is short enough to read in full, which is rarer in this category than it should be.

Merchant by merchant
Everything we pushed through this range, including the merchants it never cleared.
Merchant by merchant
| Merchant | Attempts | Cleared | Rate | What happened |
|---|---|---|---|---|
| Google Play | 63 | 57 | 90% | went through on a fresh card with the issuer's default address |
| Bing Ads | 51 | 44 | 86% | first charge and renewal four weeks later both cleared |
| Epic Games Store | 39 | 33 | 85% | went through on a fresh card with the issuer's default address |
| StockX | 25 | 0 | 0% | AVS mismatch. The ZIP on file did not match the address registered to the card. |
| Target | 21 | 7 | 33% | Geo mismatch. The connection country did not match the card's country of issue. |
Run from a Canada-region account between 14 Jun to 30 Aug 2026, with the billing address set to the issuer default unless noted. Declines were logged with the reason the gateway returned.
Failures we could not fix
Do not expect much luck on StockX. It declined on all four attempts. Target was inconsistent, two passes out of five.
What to change before you retry
- StockX: 0 of 25 cleared. Charges only happen when a bid is accepted, so the balance has to be sitting there before the seller responds. A card that funds on demand is what fails here, not the range.
- Target: 7 of 21 cleared. Target runs an address check on first orders. Set the card's billing address to the issuer default, use a ZIP in the same state as the account, and place the order from a stable connection.
Setup notes for Combo Cards
- Bank transfer is the cheap funding route here, but it is not instant. Top up a day before a renewal rather than the same morning.
- Set the billing address to exactly what Combo Cards generates for Canada. Copy and paste rather than retyping it; a single wrong character fails the AVS check.
- This is an anonymous-account product. There is no meaningful account recovery, so export the card details and the billing address the moment you create them.
What the numbers add up to
Nothing here is a dealbreaker, but nothing is a standout either. It does the job on Canada-region checkouts. If your only requirement is that the payment goes through, this range meets it.
Questions we get about 555555
What does the 555555 BIN tell a merchant?
It tells the risk engine three things before your bank is ever contacted: issuer Combo Cards, country of issue Canada, product class Debit. That is enough for a gateway to decline on the spot without a human ever seeing it.
Is 555555 a real card number?
Six digits of a sixteen-digit number. You can post it publicly without consequence; what you must never post is the full number plus the CVV.
Why would 555555 be declined if the range is fine?
Changing one variable at a time is the only way to diagnose this. Address first, then card, then the connection country. We have seen people change all three and learn nothing.
Can thousands of people share the same BIN?
That is the normal case. Every Debit card Combo Cards issues in Canada carries the same six digits. Two people on 555555 can get opposite results at the same checkout, which is why a single review is never conclusive.
Method
We bought a Combo Cards card, funded it, and pushed 199 charges through live merchant checkout pages between 14 Jun to 30 Aug 2026. Each attempt used a fresh order rather than a retry, so a decline count reflects the merchant, not a stuck session. 141 cleared.
Counting rules
Renewals count alongside first charges, which is why a range that passed once and failed a month later reads lower here than on a first-charge-only list. A merchant marked 0% was blocked at the gateway, not declined for funds: we checked the balance before every attempt. Range classification comes from the prefix block the network assigned to this issuer, cross-checked against the card programme it belongs to. Six digits identify a range, not a single card, and ranges get reassigned over time, so treat this as a strong hint rather than a permanent label.
