At a glance

Successful Viva Payments transactions where the card-issuer country differs from the customer billing country. Strong fraud signal individually, but legitimate at low rates (travelling customers, expats, gift purchases). The shape of the mismatch profile (which country pairs) is more interesting than the absolute count.

Calculation

Calculated automatically from your Viva Payments data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A Greek-headquartered consumer-goods brand on Smart Checkout. 7-day window 26 Apr 26 to 02 May 26. What the merchant should notice:
  1. 5% mismatch rate is the alert threshold. Below 3% is normal (legitimate travelers, expats). Above 5% suggests fraud testing or a campaign mismatch (your shipping policy is letting through high-risk geographies).
  2. The country pair matters more than the count. GR-billing + GB-card is benign; FR-billing + NG-card is high-risk. Open the table view to see which pairs are accumulating.
  3. Sanctions-flagged BINs (RU, IR, KP, SY, BY) should be near-zero. If they’re appearing, your SCA / risk filter is letting them through. Review Viva’s Risk dashboard configuration.
  4. 3DS challenge is likely on mismatches. Most of these will have hit a 3DS challenge from the issuer; the customer completed it (which is why they’re in this card, only successful transactions). Issuer-completed 3DS provides liability shift, you’re protected from chargeback for fraud claims, but not for “item not received” claims.
  5. POS captures don’t appear here. Card-present at terminal = same country by definition (the card is physically at the terminal location).

Known limitations / merchant FAQs

Should I block all mismatched transactions? No. Mismatched transactions are typically 2, 5% of healthy traffic and most are legitimate (travelers, expats, gift purchases). Blocking them blanket would lose 2, 5% revenue. Use Viva’s Risk engine to score each mismatch by additional signals (BIN, AVS match, 3DS outcome, velocity), and block only the high-risk subset. A spike to 8% mismatch overnight, what’s happening? Almost always one of: (1) carding attack (someone testing stolen card numbers, often very small amounts), (2) a marketing campaign sent to international audiences (legit, just shifted the mix), (3) a fraud ring targeting your category. Open Viva Risk view immediately; consider tightening cross-border rules. 3DS-completed mismatched transactions, are they safe? Issuer-completed 3DS provides liability shift for fraud-claim chargebacks (the issuer can’t bill it back as fraud). It does NOT protect against “item not received” or “service not as described” claims. So safer than non-3DS mismatch but not invincible. Why does POS not appear here? Card-present at terminal means card and customer are in the same physical location by definition. Mismatch is a card-not-present (online) concept. Sanctions BINs in my mismatch list, what do I do? Disable the BIN range in your Viva Risk configuration immediately. Ongoing transactions on sanctions-flagged BINs can expose you to OFAC / EU sanctions enforcement, regardless of fraud loss. My checkout asks for billing country, why is it missing on some? Guest checkout flows, certain wallet flows (Apple Pay), and some recurring rebills can have minimal address data. The card falls back to BIN-derived country; transactions where billing is missing show up under “Unknown” billing. JP Morgan ownership impact? None. The Risk engine and mismatch detection continue under existing Viva controls.
