What is a SWIFT code?

A SWIFT code is an 8–11 character identifier used by banks to route international wire transfers to the correct financial institution. It ensures funds reach the right bank in v the right country without ambiguity.

SWIFT stands for Society for Worldwide Interbank Financial Telecommunication. The SWIFT network connects over 11,500+ financial institutions across 220+ countries. When you initiate an international wire transfer, your bank uses the recipient's SWIFT code to locate the destination bank and route the payment correctly.

Why SWIFT code matters for your business

If you're a founder paying a supplier in Germany, hiring a contractor in Brazil, or receiving investment from a US fund, a SWIFT code is the identifier that makes that transfer possible. If you get it wrong, and the payment may fail or worse, be misrouted entirely.

What is a BIC code?

BIC stands for Bank Identifier Code. It's the ISO standard (ISO 9362) for identifying banks in international transactions and it's the formal name for what most people call a SWIFT code.

BIC and SWIFT are often mentioned together because SWIFT used the BIC code format as their standard worldwide.

SWIFT code vs BIC: what's the difference?

No such meaningful difference. BIC stands for Bank Identifier Code (defined by the ISO 9362 standard), while SWIFT refers to the Society for Worldwide Interbank Financial Telecommunication, the global messaging network that manages these codes.

Here's the full comparison:

[Table:1]

What does a SWIFT/BIC code look like?

A SWIFT code is 8 or 11 characters long. Each section tells you something specific about the bank. This structure is what allows financial institutions to route payments globally with precision.

[BANK CODE] [COUNTRY CODE] [LOCATION CODE] [BRANCH CODE]

Real SWIFT code examples

• CHASUS33: JPMorgan Chase, United States (8-character, head office)
  
• BOFAUS3N: Bank of America, United States (8-character)
  
• HSBCGB2L: HSBC, United Kingdom, London (8-character)
  
• HSBCGB2LXXX: HSBC, United Kingdom, London, head office (11-character)
  

The 8-character version routes to the bank's primary office. The 11-character version routes to a specific branch. If you're unsure which to use, the 8-character code is sufficient your bank will route from there.

SWIFT code vs IBAN: what's the difference?

This is when most founders usually find themselves lost, especially when handling European banks, payroll issues, or vendors from other countries.

IBAN means International Bank Account Number. It holds all the information about your country, bank, and individual account in one code.

[Table:3]

Can you find a SWIFT code from an IBAN?

Sometimes, yes. The first 4–8 characters of an IBAN encode the country and bank and with a lookup tool, you can often trace the associated SWIFT code. But always verify directly with the bank rather than relying on a derived code for a live transfer.

SWIFT code vs routing number

This distinction between SWIFT code and routing number matters most for US founders sending or receiving money domestically versus internationally.

[Table:4]

When you're paying a US vendor or receiving money from a US customer within the country, a routing number is all you need. The moment a transfer crosses a border, a SWIFT code is required — routing numbers don't work internationally.

How to find your SWIFT code step-by-step

If you're trying to find your SWIFT code, here are the fastest ways to do it:

1. Your bank's website

Search "[your bank name] SWIFT code." Most banks list it under their international transfers or wire payment help page. You'll usually find it in under a minute.

2. Your online banking portal

Log in and check your account details or international payment settings. Your SWIFT code is often listed alongside your account and routing numbers.

3. Your bank statement

Physical or digital bank statements frequently include your SWIFT code in the account information section — particularly if your bank processes international transactions.

4. Call or chat with your bank

Your bank's support team can confirm it immediately. Ask specifically for the SWIFT/BIC code for international wire transfers.

If you still can't find it, contact the recipient's bank directly. When you're receiving a payment, it's your responsibility to give the sender your bank's SWIFT code, not the other way around.

Do you always need a SWIFT code?

Not always. The necessity of the SWIFT code will be determined by the destination location and the payment system used. Bank transfers typically require a SWIFT code, although there are certain exceptions that should be considered prior to executing the transfer.

1. SEPA transfers (Europe)

The Single Euro Payments Area network handles transfers across 36 European countries using IBAN only. That said, some European banks may still request a BIC for verification — confirm with your bank before sending.

2. Fintech and payment platforms

Companies like Aspire use unique payment rails for making cross-border transactions which do not involve traditional SWIFT networks. That is why transfers made by using such platforms are both faster and more economical than ordinary bank wires.

3. Domestic US transfers

Within the US, you use a routing number and account number. SWIFT codes aren't part of domestic ACH or wire transfers.

If you're using your traditional bank to send money across borders, assume you need a SWIFT code. If you're using a modern payment platform, check their specific requirements — they may not need one at all.

Common mistakes with SWIFT/BIC codes

Even small errors can delay or block a payment entirely. Watch out for these:

1. Using the wrong number of characters

An 8-character code and an 11-character code aren't interchangeable in all systems. If a platform requires 11 characters and you submit 8, append XXX as the branch code.

2. Confusing SWIFT with IBAN

Submitting an IBAN where a SWIFT code is required — or vice versa — will fail the transfer. They serve different purposes. Always double-check which field you're filling in.

3. Using an outdated code

Banks change SWIFT codes when they merge, rebrand, or restructure. Always verify before a large transfer, especially if you haven't paid that recipient recently.

4. Entering the wrong country code

One wrong letter in the country code section can route your payment to the wrong country. Verify carefully against the recipient's official banking details — never guess.

When a SWIFT code doesn't match the receiving bank's records, compliance systems flag the transfer for review. What should take two days can stretch to a week. Always double-check before sending large amounts.

Fees and charges for SWIFT payments

SWIFT transfers aren't free — and the cost structure catches many founders off guard. There are typically four layers of fees involved.

1. Sender’s Fee

Your bank charges a sender fee to initiate the wire, usually a flat rate between USD $10 and USD $50+, depending on the destination.

2. Intermediary fees

SWIFT payments often pass through one or more correspondent banks before reaching the destination, and each one can deduct a fee — sometimes without disclosing it upfront. This is the most unpredictable part of the cost.

3. Receiver’s Fee

The destination bank may also charge an incoming wire fee, deducted directly from the transferred amount.

4. FX markup

If the transfer involves a currency conversion, your bank applies an exchange rate above the mid-market rate — and this is often where the real cost hides. A $10,000 wire that costs $25 to send might arrive as USD $9,920 after all deductions.

[Table:5]

Always confirm the total cost with your bank before sending, and ask the recipient whether their bank charges an incoming wire fee.

This layered, opaque cost structure is why many businesses are shifting to modern multi-currency platforms — ones that offer upfront rate transparency, faster settlement, and lower fees on cross-border payments.

How SWIFT payments actually work

Here's what happens the moment you hit "send" on an international transfer:

• You initiate the payment: Enter the recipient's account number and SWIFT code in your bank's system
  
• Your bank authenticates the transfer: They verify your identity, available funds, and compliance requirements
  
• The SWIFT message is sent: Your bank sends a standardized message to the recipient's bank, or to a correspondent bank first
  
• Correspondent banks relay the payment: If your bank doesn't have a direct relationship with the recipient's bank, the payment routes through one or more intermediaries
  
• The recipient's bank credits the account: Once the funds arrive, the bank credits the account and the transfer is complete
  

The entire process takes up to one to three business days. Transactions between major corridors such as the US, UK, and EU usually take less time. Payments made through less popular corridors will take more time.

Frequently asked questions

1. What is a SWIFT code in banking?

The SWIFT code is a unique alphanumeric code of 8-11 characters used for transferring money from one country to another. It works in collaboration with the account number.

2. What is a SWIFT code used for?

The SWIFT code is used to identify the participating banks for foreign wire transfers. In every international wire transfer through traditional banking channels, the SWIFT code indicates which bank should be either debited or credited.

3. Is SWIFT the same as BIC?

Yes. SWIFT code and BIC (Bank Identifier Code) refer to the same identifier. The two terms are used interchangeably across banks, payment platforms, and invoices worldwide.

4. How do I find my bank's SWIFT code?

Check your bank's website under international transfer or wire payment settings, review your online banking account details, or contact your bank's support team. You can also use a free lookup tool like wise.com/swift-codes.

5. Can a bank have multiple SWIFT codes?

Yes, large banks having several branches will have several SWIFT codes, with one for each branch. An eight-digit code is used to address the main bank, while an eleven-digit code is used to identify each individual branch.

6. Do all banks have SWIFT codes?

Most banks that support international transfers have a SWIFT code. Smaller regional banks or credit unions sometimes don't. In that case, you may need to use a correspondent bank's SWIFT code instead — contact your bank to confirm.

7. Is SWIFT required for all international transfers?

No. SEPA transfers within Europe typically use IBAN only, though some banks may still request a BIC. Many fintech platforms also route payments outside the SWIFT network entirely. For traditional bank-to-bank international wires, a SWIFT code is almost always required.

8. Can I send an international transfer without a SWIFT code?

Not with the conventional banking system. The absence of a SWIFT code means the destination bank can't be identified, and thus, the transaction will not take place. However, exceptions to this are SEPA transactions and money transferred using fintech payment platforms.
