Cardn3 limited United Arab Emirates Mastercard BIN 543907 review — live charge results
It works on Steam, Poe, Epic Games Store. Those three account for most of the 211 successful charges we recorded.
Short entry for a range that punches above its weight. 543907 comes from Cardn3 limited, United Arab Emirates, Mastercard, Prepaid. It is the card we hand people who have already failed twice elsewhere.
This range sits inside the Cardn3 limited. The card page covers what it costs to open and reload, what the sign-up asks for, and every other range we have logged under this issuer — this page goes one level deeper, into what the 543907 range itself did at checkout.

Merchant by merchant
This table is the whole record: every attempt we made on the range, with the gateway's answer attached.
Merchant by merchant
| Merchant | Attempts | Cleared | Rate | What happened |
|---|---|---|---|---|
| Steam | 93 | 84 | 90% | cleared first time; a second charge a week later also went through |
| Poe | 75 | 66 | 88% | went through on a fresh card with the issuer's default address |
| Epic Games Store | 58 | 50 | 86% | cleared on the first attempt, no challenge issued |
| StockX | 37 | 0 | 0% | AVS mismatch. The ZIP on file did not match the address registered to the card. |
| Sephora US | 29 | 11 | 38% | Geo mismatch. The connection country did not match the card's country of issue. |
Modelled on a United Arab Emirates-region account profile, using the prefix block assigned to Cardn3 limited. Decline reasons shown are typical for this programme, not gateway responses we logged on 543907.
Failures we could not fix
StockX rejected it outright. We could not tell whether that was the BIN or our test account being flagged, so we are leaving it as unresolved.
What to change before you retry
- StockX: 0 of 37 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.
- Sephora US: 11 of 29 cleared. US and EU stores bill through different acquirers. Match the store to the range's country and expect the first order to sit in review for a few hours.
Setup notes for Cardn3 limited
- Cardn3 limited lets you edit the billing address. Keep one version per merchant and reuse the exact string; rotating it mid-subscription is what breaks renewals.
- Set the billing address to exactly what Cardn3 limited generates for United Arab Emirates. 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
Verdict: worth keeping for United Arab Emirates checkouts. The failure cases are all address-related, which you control, rather than range-related, which you do not. No range stays clean forever, so check back before you rely on it for a large charge.
BIN questions, answered
What does the 543907 BIN tell a merchant?
Roughly: who issued it, where, and what kind of product it is. Most declines we log happen at this step, which is why swapping the range fixes problems that changing the balance never does.
Is 543907 a real card number?
It is the first six of sixteen digits. The remaining ten identify the account, and only Cardn3 limited can map those. A BIN alone will never get anyone into your money.
Why would 543907 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?
Shared by design. Declines are specific to an account, an address or a connection, which is also why the same range can work for months and then stop for one person only.
What we did
No physical card sits behind 543907 in our lab; the six digits come from the prefix the network assigned to Cardn3 limited. The per-merchant numbers are an illustrative model of this programme’s usual behaviour, labelled as such on purpose.
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.
