DEFINITION of 'Society for Worldwide Interbank Financial Telecommunications - SWIFT'

Society for Worldwide Interbank Financial Telecommunications (or SWIFT) is member-owned cooperative that provides safe and secure financial transactions for its members. Established in 1973, SWIFT uses a standardized proprietary communications platform to facilitate the transmission of information about financial transactions. Financial institutions securely exchange this information, including payment instructions, among themselves.

BREAKING DOWN 'Society for Worldwide Interbank Financial Telecommunications - SWIFT'

SWIFT neither holds funds on its own nor manages external client accounts. The cooperative began operating in 15 countries in 1973 and now operates in 210 countries, linking more than 10,000 financial institutions. Today the co-op delivers over 24,000,000 messages a day - up from 2.4 million messages per day in 1995.

SWIFT is headquartered in Belgium and has offices in the United States, Brazil, Australia, India, Japan, Korea, Austria, Belgium, France, Germany, Italy, South Africa, Spain, Sweden, Switzerland, the United Kingdom, UAE and Russian Federation.

Prior to SWIFT, the only reliable means of message confirmation for international funds transfer was Telex. However, a range of issues plagued Telex, including low speed, security concerns, and a free message format. SWIFT’s unified system of codes to name banks and describe transactions was a welcome change.

Breaking Down SWIFT Transactions

For money transfers, SWIFT assigns each participating financial organization a unique code with either eight or eleven characters. The code has three interchangeable names: the bank identifier code (BIC), SWIFT code, SWIFT ID, or ISO 9362 code.

For example, the Italian bank UniCredit Banca, headquartered in Milan, has the 8-character SWIFT code UNCRITMM. First four characters reflect the institute code (UNCR for UniCredit Banca), the next two are the country code (IT for Italy), and the final characters specify the location/city code (MM for Milan). If an organization decides to use a code with eleven characters, the last three optional characters can reflect individual branches. For example, the UniCredit Banca branch in Venice may use the code UNCRITMMZZZ.

Assume a customer of a T.D. Bank branch in Boston wants to send money to his friend who banks at the UniCredit Banca branch in Venice. The Bostonian can walk into her T.D. Bank branch with her friend’s account number and UnicaCredit Banca Venice’s unique SWIFT code. T.D. Bank will send a SWIFT message for a payment transfer to the specific UniCredit Banca branch via its secure network. Once Unicredit Banca receives the SWIFT message about the incoming payment, it will clear and credit the money to the her friend’s account.


SWIFT and IBAN (International Bank Account Number) both come in handy when identifying parties in money transfers; however, while a SWIFT code is used to identify a specific bank, the IBAN code is used to identify an individual account involved in an international transaction.
