In the world of international finance, a SWIFT code (also known as a BIC - Bank Identifier Code) serves as a crucial identifier for banks, streamlining the routing of payments across borders. It can identify a bank in seconds and send payment quickly.
The SWIFT (Society for Worldwide Interbank Financial Telecommunication) network utilizes BIC codes to facilitate secure payments, including international bank wires, money transfers, and SEPA payments. The International Standard for SWIFT/BIC codes is ISO 9362 which is why you sometimes see this term used in place of SWIFT.
Example of a SWIFT BIC code structure.
What is a SWIFT Code?
A SWIFT code is a standard format used when making international transfers between banks and financial institutions.
SWIFT stands for the Society for Worldwide Interbank Financial Telecommunication. SWIFT owns and administers the BIC system.

All BIC and SWIFT codes consist of 8 to 11 characters long and follow the same format.
The main difference between SWIFT and IBAN lies in what the codes convey. An IBAN is an International Bank Account Number. The international system is used to identify and ensure that payments are made to the correct recipient account. An IBAN can contain up to 34 characters in both letters and digits.
The Role of SWIFT in Global Transactions
The SWIFT service creates an international level of connectivity that speeds up global commerce and brings the world a little closer together. In 2021, more than 11,000 global SWIFT member institutions sent an average of 42 million messages per day, marking an increase of 11.4% over 2020.
Originally, SWIFT was created to only facilitate communication about treasury and correspondent transactions. The original design for SWIFT was to create a way for banks to communicate more efficiently and securely among themselves. The word “communicate” is always used because SWIFT is only a messenger between banks.
A SWIFT code works when financial institutions like banks and clearing systems, use it to identify where to send money internationally. In addition to the sending and receiving bank, a SWIFT payment may also require an intermediary bank.

When both banks have a relationship through Nostro and Vostro accounts, SWIFT transfers are immediate and direct. Once a correspondent bank is located (meaning they have a relationship with the other two banks involved) the SWIFT transaction can proceed. The more banks involved in these international transactions, the more fees will be incurred.
Validating and Verifying SWIFT Codes
Validating a SWIFT code is a simple but important step before making a cross-border payment. There are resources online to check and validate a SWIFT code once you have it. Just copy and paste the code into a SWIFT code checker and the search engine will tell you whether it’s valid or not.
The best way to confirm a SWIFT code is to use an online tool like our SWIFT Code Checker. Many people ask if validating a SWIFT code is the same as verifying it.
- âś… Validation checks the format of the code.
- 🔍 Verification goes further.
If you’re unsure what SWIFT code you need, use our SWIFT Code Checker Tool.
Consequences of Using an Incorrect SWIFT Code
❌ Using a partial code (e.g. Yes. No. The transfer may be delayed, rejected, or sent to the wrong bank. In the best case, it’s rejected by the SWIFT network and the funds are returned in one to three weeks. A minor issue, like the wrong branch code, may be repaired quickly. To avoid any delivery problems, you should use a SWIFT checker online to ensure that the SWIFT number of the receiving bank is correct.

SWIFT vs. Other Systems
SWIFT will get you overseas. However, they are totally different in structure, subcodes, and function. To date, the SWIFT network is the most popular international payment system, surpassing the IBAN (international bank account number) system.
BIC, CHAPS, IBAN, SWIFT and vIBANS are acronyms you probably encounter if you do business overseas and make payments internationally. So, for businesses with a global presence, it would be beneficial to know these ahead of time. BIC means Bank Identification Code or Bank Identifier Code.
It cost money to send money internationally, no matter what. Your rates just depend on where it’s going, how it gets there, and who’s involved. If you’re sending funds to a bank that requires an intermediary, then there will be additional charges involved there; that your bank may not be able to avoid.
SWIFT's Infrastructure and Security
The SWIFT secure messaging network is run from three data centres, located in the United States, the Netherlands, and Switzerland. These centres share information in near real-time. In case of a failure in one of the data centres, another is able to handle the traffic of the complete network.
SWIFT moved to its current IP network infrastructure, known as SWIFTNet, from 2001 to 2005, providing a total replacement of the previous X.25 infrastructure. The process involved the development of new protocols that facilitate efficient messaging, using existing and new message standards. The adopted technology chosen to develop the protocols was XML, which now provides a wrapper around all messages legacy or contemporary.
During 2007 and 2008, the entire SWIFT network migrated its infrastructure to a new protocol called SWIFTNet Phase 2. The main difference between Phase 2 and the former arrangement is that Phase 2 requires banks connecting to the network to use a Relationship Management Application (RMA) instead of the former bilateral key exchange (BKE) system.
According to SWIFT's public information database on the subject, RMA software should eventually prove more secure and easier to keep up-to-date; however, converting to the RMA system meant that thousands of banks around the world had to update their international payment systems to comply with the new standards.
SWIFT has become the industry standard for syntax in financial messages. Messages formatted to SWIFT standards can be read and processed by many well-known financial processing systems, whether or not the message travelled over the SWIFT network.
SWIFT cooperates with international organizations to define standards for message format and content.
SWIFT Oversight and Criticism
SWIFT is not a payment system and thus neither regulated nor supervised as such, but is nevertheless deemed to be systemically important and thus under the "oversight" of public authorities. and the European Central Bank) started acting as joint overseers, with the National Bank of Belgium (NBB) in a lead role. In 2012, this framework was complemented by a "SWIFT Oversight Forum" including additional central banks. As of 2024, in addition to the G10 central banks, the SWIFT Oversight Forum included the national central banks of Argentina, Australia, Brazil, China, Hong Kong, India, Indonesia, Korea, Mexico, Russia, Saudi Arabia, Singapore, South Africa, Spain, and Turkey.
Swift has been criticised for inefficiency. In 2018, the London-based Financial Times noted that transfers frequently "pass through multiple banks before reaching their final destination, making them time-consuming, costly and lacking transparency on how much money will arrive at the other end".
Swift has since introduced an improved service called "Global Payments Innovation" (GPI), claiming it was adopted by 165 banks and was completing half its payments within 30 minutes. The new standard which included Swift Go was supposed to be utilised in receiving and transferring low-value international payments.
One of the significant changes was the transaction amount, which would not differ from start to end. However, as of 2023, uptake was mixed. For instance, Alisherov Eraj, Alif Bank Treasury Department Swift Transfers & Banking Relationship Expert in the Republic of Tajikistan, describes that the leading cause for the late Swift Go adoption in Tajikistan was the Core Banking System itself.
After the publication of these articles, SWIFT quickly came under pressure for compromising the data privacy of its customers by allowing governments to gain access to sensitive personal information.
Der Spiegel reported in September 2013 that the National Security Agency (NSA) widely monitors banking transactions via SWIFT, as well as credit card transactions. The NSA intercepted and retained data from the SWIFT network used by thousands of banks to securely send transaction information.
SWIFT was named as a "target", according to documents leaked by Edward Snowden.
SWIFT and International Sanctions
In January 2012, the advocacy group United Against Nuclear Iran (UANI) implemented a campaign calling on SWIFT to end all relations with Iran's banking system, including the Central Bank of Iran. Senate Banking Committee unanimously approved sanctions against SWIFT aimed at pressuring it to terminate its ties with blacklisted Iranian banks.
Expelling Iranian banks from SWIFT would potentially deny Iran access to billions of dollars in revenue using SWIFT but not from using IVTS. In November 2024, Iran implemented a paradigm shift approach to shift the focus from the SWIFT payment system by initiating the concept of bringing ACUMER.
Following the 2022 Russian invasion of Ukraine, the foreign ministers of the Baltic states Lithuania, Latvia, and Estonia called for Russia to be cut off from SWIFT.

Security Breaches and Incidents
In 2016 an $81 million theft from the Bangladesh central bank via its account at the New York Federal Reserve Bank was traced to hacker penetration of SWIFT's Alliance Access software, according to a New York Times report.
Both attacks involved malware written both to issue unauthorized SWIFT messages and to conceal that the messages had been sent. After the malware sent the SWIFT messages that stole the funds, it deleted the database record of the transfers and then took further steps to prevent confirmation messages from revealing the theft.
In May 2016, Banco del Austro (BDA) in Ecuador sued Wells Fargo after Wells Fargo honoured $12 million in fund transfer requests that had been placed by thieves. In this case, the thieves sent SWIFT messages that resembled recently cancelled transfer requests from BDA, with slightly altered amounts; the reports do not detail how the thieves gained access to send the SWIFT messages.
BDA asserts that Wells Fargo should have detected the suspicious SWIFT messages, which were placed outside of normal BDA working hours and were of an unusual size.
In March 2022, Swiss newspaper Neue ZĂĽrcher Zeitung reported about the increased security precautions by the State Police of Thurgau at the SWIFT data centre in Diessenhofen. After most of the Russian banks had been excluded from the private payment system, the risk of sabotage was considered higher.
