Cardflo’s country-based routing module facilitates configuring payments flow based on geographical conditions. Establish rules for directing transactions to specific acquirers or payment methods depending on the origin of the card or the customer's location.
Defining these parameters ensures compliance with local regulations and leverages domestic acquiring footprints where available. It optimises for factors specific to geographical processing, contributing to more predictable authorisation rates and efficient local payment experiences.
Country-based routing directs transactions through local acquirer partners, significantly reducing cross-border interchange fees and improving approval rates. This method leverages regional MIDs to ensure payments are processed efficiently and cost-effectively.
Country-based routing overview
Geographical routing in Cardflo begins by defining the primary country indicator for a transaction. Select between the issuer country, the billing address country, the shipping address country, or the IP address country, establishing the foundational determinant for subsequent rule evaluation.
This initial selection dictates which geographical data point the routing engine will prioritise during rule execution and acquirer selection. The chosen indicator is then used to classify transactions as either domestic or cross-border, which subsequently influences the available acquirers and payment methods for a given transaction based on their operational territories.
The system supports nested rule sets, allowing for granular control over how different country indicators interact with one another. For example, a primary rule might classify a transaction by issuer country, with a secondary rule applying a different routing logic if the billing country differs.
Cardflo’s engine evaluates these conditions in a user-defined sequence, processing rules from highest to lowest priority, ensuring that only the most appropriate routing logic is applied based on the merchant’s specific requirements for different markets and customer segments.
Merchants maintain full control over the ordering and weighting of country-based conditions against other routing criteria, such as transaction currency or amount. This means a country-specific rule can be elevated to supersede a general currency-based rule, for instance, or vice versa.
The interface provides clear visualisation of the rule hierarchy, enabling administrators to predict routing outcomes and perform A/B tests on rule efficacy before deploying changes to live traffic, thereby ensuring optimal payment orchestration in diverse geographical contexts.
How country-based routing works
Select primary country indicator
Merchants choose the decisive geographical data point for routing. Options include the card issuer's country, the customer's billing address country, their shipping address country, or the transaction's originating IP address country. This selection establishes the foundational criterion for all subsequent country-based rule evaluation and application.
Define domestic and cross-border classifications
Based on the chosen primary indicator, define specific country lists or ranges that qualify a transaction as domestic versus cross-border. For instance, transactions where the issuer country matches the merchant's operating country are marked domestic. This classification informs the available acquirers and scheme fees that apply to the transaction.
Configure acquirer and payment method assignments
Map specific countries or region groupings to preferred acquirers and local payment methods. For example, all transactions with an issuer country of Germany (DE) can be routed to a German acquirer configured on the platform, or directed to SEPA Direct Debit as the preferred payment method, ensuring optimal local processing.
Order country-based conditions with global rules
Position country-specific rules within the overall routing logic, determining their precedence against other criteria like transaction amount or currency. A country rule can override a general rule if it is given higher priority, allowing for fine-tuned control over which conditions are evaluated first for a given payment.
Why country-based routing matters
Manage scheme compliance and regional mandates
Certain payment schemes have country-specific regulations or mandates, such as strong customer authentication requirements, that vary by jurisdiction. Directing transactions through infrastructure that supports these local requirements based on country rules ensures compliance. This approach limits exposure to non-compliance penalties and reduces the risk of transaction declines due to unmet regional standards, maintaining regulatory adherence.
Refine fraud prevention strategies regionally
Geographical routing enables the application of fraud tools and thresholds that are tailored to specific country risk profiles. For example, transactions originating from high-risk IP countries can be directed through enhanced fraud screening, or specific payment methods can be restricted in certain regions. This dynamic application of risk management based on country data contributes to a more effective, localised fraud prevention posture.
Country-based routing use cases
European streaming launch routing
A streaming publisher launching separately in France, Germany and Spain must route one-off content purchases according to the viewer’s country without confusing location with currency. Cardflo evaluates permitted billing, IP and device-country signals, then applies geo-fenced rules that favour an appropriate domestic connection from its acquirer partner network.
Regional warehouse checkout routing
A retailer fulfilling orders from regional warehouses needs card payments directed according to the shopper’s country, while delivery and billing addresses may point to different territories. Cardflo applies a defined location hierarchy and routes eligible transactions to domestic acquirer partners, helping finance teams reduce cross-border scheme fees and reconcile regional settlement.
Franchise territory payment routing
A restaurant group operating national franchise entities must associate online collection orders with the correct country operation, even when one checkout serves several territories. Cardflo combines outlet, cardholder and order-location signals within geo-fenced rules, directing transactions to the preferred regional acquirer partner and preserving country-level reporting for each franchise organisation.
Border region location conflicts
A merchant serving customers near national borders may receive conflicting IP, device, billing and delivery-country signals, creating a risk of choosing the wrong domestic acquiring route. Cardflo applies a configurable evidence hierarchy, records the routing decision and sends qualifying transactions to the preferred acquirer partner for the resolved cardholder market.
Country-based routing by the numbers
Typical reduction in processing costs when moving from inter-regional to domestic interchange rates, depending on the specific card schemes and regional caps in place.
An observed increase in successful authorisations when transactions are processed locally, as domestic issuers are less likely to flag the payments for potential fraud.
The additional time required for a routing engine to perform a BIN lookup and evaluate geographic rules, which is generally negligible in the context of a total authorisation cycle.

Questions about Country-based routing
How does country-based routing differ from simple currency-based routing?
Currency-based routing directs payments based on the currency requested by the customer, whereas country-based routing uses the issuer's location derived from the BIN. Relying solely on currency can be misleading, as a customer may pay in EUR using a UK-issued card.
Country-based routing ensures the transaction is handled by an acquirer that has the most favourable relationship with that specific issuing region, addressing both the settlement cost and the authorisation probability rather than just the denomination of the funds.
What is the impact of country-based routing on interchange fees?
Interchange fees are often capped by regional regulations, such as the caps within the European Economic Area. When a transaction is processed cross-border, these caps may not apply, or the merchant may be subject to 'inter-regional' interchange rates which are significantly higher.
By using country-based routing to keep the transaction domestic, merchants can qualify for lower intra-regional or domestic interchange rates, directly reducing the total cost of acceptance for each successful transaction.
Can country-based routing help with Strong Customer Authentication (SCA) compliance?
Yes, it can. SCA requirements under PSD2 are specific to the EEA.
Routing transactions through an EEA-based acquirer when the issuer is also in the EEA ensures that the 3D Secure protocols are handled according to local standards.
If an EEA transaction is routed to a non-EEA acquirer, it might be classified as 'out of scope' or 'one-leg out', which can lead to complications in how the issuer applies risk-based authentication and potentially result in higher decline rates.
Does a merchant need multiple legal entities to use country-based routing?
Typically, to get the full benefit of domestic processing, a merchant needs a local legal entity and a local MID in the target region. However, some global PSPs allow for regional routing without separate entities, though the cost savings may be less pronounced.
The most efficient setup involves having an acquirer in the same jurisdiction as the card issuer, which generally requires a local presence to satisfy KYB and regulatory requirements of the acquirer.
How does BIN lookup accuracy affect the routing process?
The effectiveness of country-based routing is highly dependent on the quality of the BIN database. Since banks regularly launch new BIN ranges, the database must be updated frequently.
Inaccurate BIN data can lead to misrouting, where a domestic transaction is treated as international or vice versa, resulting in unnecessary fees or declines. Most orchestration platforms use enterprise-grade BIN intelligence to ensure high accuracy in identifying the issuer's country and card type.
Can routing rules be set for specific country groups like the EEA?
Yes, routing engines allow for the grouping of countries into logical territories.
For example, all transactions from issuers within the European Economic Area can be treated as a single group and routed to a primary European acquirer to take advantage of harmonised regulations and interchange caps.
Similar groups can be created for regions like LATAM or APAC to simplify the management of routing logic across a large number of individual countries.
