The overview
US-facing merchants that establish subsidiaries or legal entities in Europe and the United Kingdom often do so to access local merchant acquiring and minimise the impact of cross-border interchange fees.
By holding an EU or UK licence, a merchant can process US dollar transactions via domestic gateways or regional acquirers, potentially improving authorisation rates due to higher issuer trust in localised merchant IDs.
This structure necessitates a sophisticated payment stack capable of managing multi-currency settlement and complex smart routing logic. Merchants must navigate the differences between the European Banking Authority's mandates and the UK's post-Brexit regulatory framework, particularly concerning Strong Customer Authentication and PSD2 requirements.
Managing this dual-region setup requires careful oversight of MCC assignment and the coordination of varied merchant accounts to ensure that traffic is directed to the acquirer most likely to approve a specific transaction type while remaining compliant with card scheme rules regarding cross-border acquiring.
How it works
Local Entity Formation
The merchant establishes a registered business entity within the European Economic Area or the United Kingdom.
This entity serves as the contractual party for the regional acquirer, allowing the merchant to apply for a local MID rather than relying solely on a US-based merchant account for international traffic.
Regional Acquirer Integration
Financial operations are connected to local PSPs or acquirers that specialise in Euro or Sterling processing.
This step involves configuring the gateway to recognise the geographic origin of the cardholder's BIN and routing the transaction to the most appropriate regional infrastructure to optimise the cost of processing.
Smart Transaction Routing
A payment orchestration layer analyses incoming transaction metadata in real time.
For US-facing traffic originating from European entities, the system determines the optimal path based on historical decline reasons, current scheme fees, and the specific risk appetite of the issuer, ensuring the highest probability of a successful authorisation.
Compliance Monitoring
The merchant implements SCA protocols according to the local jurisdiction’s requirements. While US-issued cards are technically out of scope for mandatory 3DS under PSD2, using a European structure often triggers specific filtering.
Transactions are monitored to ensure adherence to both regional AML laws and global card scheme regulations.
Why it matters
Interchange Fee Optimisation
Processing transactions via a local entity rather than as a cross-border merchant can lead to significant reductions in interchange and scheme fees.
Regional regulations, such as those in the EEA, cap interchange for consumer cards, which is often lower than the rates applied to international transactions processed directly through US acquirers, improving the merchant's net margin.
Improved Authorisation Rates
Issuer behaviour often favours domestic or regional processing. When a US card is processed through a European entity with high reputational standing, issuers may apply less stringent fraud filters compared to a merchant with no local presence.
This structure helps minimise false positives and reduces the frequency of hard declines during the authorisation process.
Regulatory notes
PSD2 and SCA Compliance
Merchants operating via a European subsidiary must comply with the Revised Payment Services Directive. This includes applying Strong Customer Authentication to in-scope transactions.
Failure to manage 3DS correctly can result in soft declines or regulatory penalties. Even for one-leg-out transactions involving US cardholders, merchants must ensure their data processing adheres to EBA guidelines regarding security and transparency.
FCA Authorisation Rules
The UK's Financial Conduct Authority maintains distinct requirements for payment services.
Merchants using a UK-based structure must ensure that their PSP is authorised to operate within the UK and that their contractual arrangements reflect the current post-Brexit legal landscape, specifically regarding data privacy and the protection of consumer financial information under the UK GDPR.
Use cases
SaaS Subscription Models
US-based software providers with a global user base use European entities to manage recurring payments, utilising account updaters and local MIDs to maintain high retention rates for international subscribers.
Direct-to-Consumer Retail
E-commerce brands shipping to or from Europe use this structure to offer local payment methods and reduce the foreign exchange fees typically passed on to consumers during the checkout process.
Digital Marketplaces
Platforms with complex payout requirements across multiple borders use an EU/UK structure to centralise their settlement processes and manage KYB requirements under regional regulatory frameworks.
By the numbers
This represents a common range observed when merchants move from purely cross-border processing to a localised acquiring strategy in supportive jurisdictions.

Common questions.
Why should a merchant with a US focus consider an EU or UK legal structure for payments?
Establishing an EU or UK structure allows a merchant to access the European payments ecosystem as a domestic participant. This frequently results in lower interchange costs because of regional fee caps and can improve the issuer's perception of the transaction.
For US merchants with high volumes of international traffic, this can lead to an increase in authorisation rates.
It also facilitates the implementation of regional security standards like 3DS, which may be expected by certain global issuers even for transactions that are technically out of scope for PSD2.
How does PSD2 and SCA affect US-facing merchants with European structures?
PSD2 requires Strong Customer Authentication for transactions where both the issuer and the acquirer are within the EEA. If a US merchant uses a European acquirer but the cardholder is in the US, the transaction is 'one-leg-out' and technically not subject to mandatory SCA.
However, many European PSPs and acquirers apply SCA by default to maintain security standards. Merchants must ensure their gateway can intelligently apply 3DS to satisfy regional risk profiles without creating unnecessary friction for their primary US customer base.
What are the common challenges when managing multiple MIDs across different geographic regions?
The primary challenges include data fragmentation, varying settlement timelines, and the complexity of reconciliations. Different acquirers use different reporting formats and ARN formats, making it difficult to track a single customer journey across regions.
Additionally, merchants must ensure they do not violate card scheme rules regarding 'jurisdiction shopping' where a transaction is routed to a region solely to avoid fees without a legitimate business presence. Maintaining separate reserve requirements across multiple acquirers also impacts cash flow management.
Can a merchant settle in USD while using a European or British acquiring bank?
Yes, many European and UK acquirers offer multi-currency settlement. This allow a merchant to process a transaction in USD, have the funds captured in USD, and then settled into a USD-denominated bank account.
This minimizes foreign exchange fees and prevents the currency conversion costs that usually occur when a US-based acquirer processes a non-US card.
However, the merchant must ensure their corporate bank account is capable of accepting the specific currency and that the acquirer supports the desired settlement pair.
How does the UK's departure from the EU affect this specific payment structure?
Since Brexit, the UK and the EEA are separate regulatory zones. A merchant processing traffic through a UK entity may face cross-border fees when treating EEA cardholders as domestic, and vice versa.
Card schemes like Visa and Mastercard have increased cross-border interchange rates between the UK and EEA.
Merchants with significant traffic in both regions often find it necessary to maintain separate structures in both the UK and an EEA member state to fully optimise their processing costs.
What is the role of a BIN in routing US-facing traffic through a European entity?
The BIN, or Bank Identification Number, identifies the issuer and the country of origin of the card. A smart-routing gateway uses the BIN to determine which regional MID should process the transaction.
If the merchant's goal is to improve authorisation for US cards, they may test routing through their European entity to see if the specific issuer has a better response to that acquirer.
However, this must be balanced against the potential for higher cross-border fees if the card is used outside the entity's home region.
