For businesses selling internationally, expanding into higher-risk markets can create significant growth opportunities. However, accepting payments from high-risk countries can also create additional challenges around payment processing, fraud prevention, Anti-Money Laundering (AML), sanctions screening and merchant account approval.
For UK businesses, having the right payment infrastructure is particularly important when customers are located in jurisdictions that payment providers or financial institutions consider higher risk.
This doesn’t necessarily mean that payments from every higher-risk country are prohibited. Instead, merchants and payment providers need to assess the specific customer, transaction, country, business activity and applicable regulatory requirements.
In this guide, we’ll explain how high-risk country payment processing works, what UK merchants need to consider and how specialist payment solutions can help businesses accept international payments more efficiently.
A high-risk country is generally a jurisdiction that presents additional financial, regulatory, fraud, sanctions or money-laundering risks.
Payment providers may consider factors such as:
Importantly, high risk does not automatically mean prohibited.
Payment providers assess countries and transactions using their own risk policies, as well as applicable laws and regulations.
In some circumstances, yes.
However, the ability to process a transaction depends on several factors, including:
UK businesses should never assume that a payment can be accepted simply because a particular country isn’t specifically excluded by their payment gateway.
Financial sanctions can prohibit transactions involving designated individuals, organisations or governments, and in some circumstances can restrict financial services involving particular countries. The UK’s sanctions regime is administered by the Office of Financial Sanctions Implementation (OFSI).
International transactions can create additional challenges for merchants and payment providers.
Certain markets may present higher levels of card fraud, account takeover or fraudulent transactions.
Payment providers therefore use additional transaction monitoring and risk controls.
Businesses may need stronger customer due diligence when dealing with higher-risk customers or transactions.
The FCA states that firms should take a risk-based approach to customer due diligence and apply enhanced due diligence in higher-risk situations.
Merchants need to consider whether customers, beneficial owners, counterparties or other parties involved in a transaction are subject to applicable sanctions.
UK sanctions can apply to transactions involving designated individuals and entities, regardless of where they are located.
A payment processor may have its own restricted-country or prohibited-business policies.
This means that even where a transaction may be legally possible, a particular payment provider may decide not to support it.
High-risk country payment processing refers to payment infrastructure designed to help businesses manage transactions involving customers or markets that present increased financial or regulatory risk.
Depending on the merchant and market, solutions can include:
The right combination depends on the countries being targeted and the merchant’s industry.
Before expanding into a higher-risk market, merchants should consider several important areas.
Start by identifying which countries your payment provider supports.
Payment providers often maintain their own lists of:
These lists can change, so merchants should regularly review their provider’s current requirements.
Sanctions compliance should be a fundamental part of international payment processing.
UK businesses need to understand whether sanctions apply to:
The FCA recommends that firms maintain systems and controls capable of meeting their financial sanctions obligations, including checking relevant parties against the UK Sanctions List.
Strong KYC procedures can help merchants understand who they are doing business with.
Depending on the business model and risk level, verification may include:
Higher-risk situations may require enhanced due diligence.
It’s important to distinguish between high-risk countries and high-risk customers.
A customer may present additional risk because of:
The FCA notes that higher-risk situations can require enhanced due diligence and ongoing monitoring.
Choosing the right payment methods can make a significant difference to approval rates and customer experience.
Visa and Mastercard remain important for international eCommerce.
Benefits include:
However, card payments can expose merchants to higher fraud and chargeback risks in certain sectors.
Bank transfers can be useful for larger transactions and business-to-business payments.
They can provide:
However, international transfers may involve additional banking checks and settlement times.
Open Banking provides account-to-account payment capabilities in supported markets.
For eligible UK and European transactions, it can provide an alternative to traditional card processing.
Potential advantages include:
The availability of Open Banking varies by country, provider and use case.
Local payment methods can be particularly important when expanding internationally.
Depending on the market, these may include:
Supporting the payment method customers already know can improve checkout conversion.
Businesses accepting international payments should take a proactive approach to risk management.
Monitor transactions for unusual patterns, unexpected locations and abnormal payment behaviour.
Transaction limits can help control exposure to unusually large or suspicious payments.
Modern payment platforms can use:
Know who your customers are and understand the nature of their transactions.
High chargeback levels can negatively affect your merchant account and may lead to additional scrutiny from acquiring partners.
These terms should not be treated as interchangeable.
A high-risk country may simply have a higher level of financial, regulatory or fraud risk.
A sanctioned country or jurisdiction may be subject to specific legal restrictions.
UK sanctions can be geographic, thematic or targeted at specific individuals and entities. The UK Government maintains current sanctions regimes and designations, and the rules can change.
Therefore, merchants should not create a simple list of “countries we can accept” and assume it will remain accurate indefinitely.
Always check the current requirements applicable to the transaction.
Certain industries are more likely to require specialist payment solutions when accepting international transactions.
These can include:
These businesses may already be classified as high risk by banks or acquiring institutions, and adding international transactions can increase the complexity of payment processing.
A suitable payment provider should understand both your industry and your target markets.
When comparing providers, consider:
Does the provider support the countries you want to target?
Can customers pay using the methods they prefer?
Can you process GBP, EUR, USD and other relevant currencies?
What tools are available to identify suspicious transactions?
How quickly can you access your funds?
Does the provider have appropriate AML, KYC and sanctions controls?
Does the provider have experience working with businesses in your industry?
When applying for international high-risk payment processing, providers may request additional information.
This can include:
Providing accurate and complete information can help make the underwriting process more efficient.
Before launching in a new market, create a payment and compliance checklist.
A clear strategy can help reduce payment problems as you expand.
Even if a country is supported, an individual transaction can still be declined.
Reasons can include:
A declined transaction does not necessarily mean that the country itself is prohibited
At Merchant Connect, we help businesses explore payment solutions for complex and higher-risk industries.
Our solutions can include:
We work with businesses that may have difficulty obtaining suitable payment infrastructure through traditional providers.
The right solution depends on your industry, target countries, transaction profile and compliance requirements.
Accepting payments from high-risk countries requires more than simply finding a payment gateway that accepts international cards.
Businesses need to consider country restrictions, sanctions, AML, KYC, fraud prevention, chargebacks, payment methods and the requirements of their acquiring partners.
For UK businesses, compliance should remain a priority. The FCA expects firms to take a risk-based approach to financial crime controls, while OFSI provides guidance on complying with UK financial sanctions.
With the right payment provider and appropriate risk controls, businesses can explore international growth while maintaining a robust payment infrastructure.
If your business needs help finding high-risk payment processing solutions for international customers, Merchant Connect can help you explore suitable options.
