International banking reference
A practical quick-reference guide to common bank codes, account identifiers, compliance terms and international payment terminology.
Account and institution identifiers
These identifiers help banks and payment providers direct payments to the correct account and institution.
A standardised account identifier used to help process domestic and cross-border payments. Its exact length and structure depend on the country that issued the account.
An IBAN identifies the account. It does not by itself identify every operational detail of the receiving bank.
An international identifier used for financial institutions and other business parties. A BIC normally contains eight characters, with an optional three-character branch identifier.
BIC is often informally called a SWIFT code, although BIC is the formal identifier and Swift is the messaging network and standards organisation.
Swift provides secure financial messaging used by banks and financial institutions to exchange payment instructions and other financial information.
Swift normally carries the payment message. It does not itself hold the sender’s or recipient’s money.
A globally recognised identifier that connects a legal entity to authoritative reference information such as its official name and registered address.
LEIs are commonly relevant in regulated financial markets and transactions where clear legal-entity identification is required.
A reference assigned to a payment or transaction so it can be identified in records, statements or support enquiries.
The term and format vary between countries and providers. In UK taxation, UTR can instead mean Unique Taxpayer Reference.
A unique reference attached to qualifying Swift payment messages so participating institutions can trace the payment through the processing chain.
UETR is specifically associated with payment tracking and should not be confused with every provider’s general transaction ID.
Payment schemes
These terms describe payment schemes and processes rather than individual bank accounts.
A framework that uses harmonised rules for euro payments across participating European countries.
SEPA concerns payments in euros. A business does not necessarily need to be located in the euro area to hold an eligible euro account.
A standard euro credit transfer made under the SEPA Credit Transfer scheme between participating payment service providers.
Processing time, cut-off times and availability depend on the provider and the circumstances of the payment.
An instant euro payment scheme designed to make eligible funds available to the recipient within seconds, at any time of day.
Both the sending and receiving payment service providers must support the relevant instant-payment service.
A euro payment method in which the creditor collects money from the payer’s account under an agreed mandate.
Consumer and business-to-business direct debit arrangements may follow different rules.
A UK payment system used for eligible pound sterling transfers between participating institutions.
Transaction limits, availability and timing are determined by the participating provider.
A UK same-day payment system commonly used for time-sensitive or higher-value pound sterling payments.
Fees and submission deadlines vary between banks and payment providers.
Compliance and verification
The process used to identify and verify a customer and understand the nature of the intended business relationship.
For companies, checks can include directors, shareholders, beneficial owners, business activity and expected transactions.
The wider process of collecting and assessing customer information, ownership, purpose, expected activity and risk.
Due diligence may continue after account opening through ongoing reviews and transaction monitoring.
Additional checks applied when a relationship, ownership structure, country, activity or transaction profile presents increased risk.
EDD can involve more detailed evidence about funds, ownership, counterparties and commercial activity.
The individual who ultimately owns or controls a company or benefits from its activities, even when ownership is held through another company or structure.
A person entrusted with a prominent public function, or in some circumstances a connected family member or close associate.
PEP status does not automatically imply wrongdoing but normally requires closer risk assessment and monitoring.
A document used to verify a person’s residential address or, in some contexts, a company’s operational or correspondence address.
Accepted documents and permitted document age vary by provider.
International payment terminology
The euro is a major international currency and the official currency of the euro area. It is widely used for trade, invoices, savings and cross-border business payments.
A euro account can help a business receive and send euro payments without converting every transaction into another operating currency.
SEPA provides harmonised rules for euro credit transfers and direct debits across participating countries, making eligible euro payments more consistent.
Standard and instant payments are separate services. Availability, fees, limits and processing depend on the account provider and the receiving institution.
Important distinctions
Several banking terms appear together on payment forms, but they perform different functions.
Before sending a payment
Confirm the beneficiary name, account number or IBAN and any required institution code before authorising the payment.
Include an invoice number, customer reference or other information that allows the beneficiary to identify the payment.
Check the currency, payment scheme, estimated processing time, potential intermediary fees and recipient-country requirements.
Banking terminology, document requirements, payment availability, limits, fees and processing times vary between countries and providers. Always follow the instructions shown by the relevant bank or payment institution and verify recipient details before sending money.
