If you’ve ever stared at a bank remittance form thinking:
“Why does sending money feel harder than sending a rocket into space?”
You’re not alone.
Whether it’s:
-
paying overseas tuition
-
sending rent while studying abroad
-
receiving salary from a foreign employer
-
settling international trade invoices
Most people don’t lose money because they’re careless.
They lose money because SWIFT, IBAN, and ABA sound like alien languages.
Enter one wrong code →
❌ delays
❌ extra fees
❌ returned transfers
❌ or worst case: money “disappears” for weeks
This article strips away the jargon and gives you a mental map you’ll never forget, so the next time you wire money internationally, you do it calmly and correctly.

Real-World Remittance Guide (What to Use & When)
01️⃣ SWIFT Code
The “ID Card” of Global Banks
What it really is (no fluff)
The SWIFT Code (also called BIC) identifies which bank your money should go to in the global banking system.
Think of it as:
📌 The international postal code for banks.
Without it, your money has no idea which bank network to enter.
As of 2025:
-
Used by 11,000+ banks
-
Covers 200+ countries
-
Mandatory for almost all cross-border transfers
Structure (decoded like a human)
A SWIFT code has 8 or 11 characters:
-
ICBK → Bank name (Industrial & Commercial Bank of China)
-
CN → Country (China)
-
BJ → City (Beijing)
-
JJM → Branch (optional)
If you see XXX at the end → it means main branch.
📌 Good to know:
Most transfers work fine with the 8-digit version.
When you need it
✅ Always, for international remittances
It tells the global banking system where to route your money.
02️⃣ IBAN
Europe’s “Precise Coordinates” for Accounts
What it actually does
An IBAN (International Bank Account Number) identifies a specific personal or corporate account, mainly in Europe.
If SWIFT is the bank’s address,
IBAN is the exact apartment number.
Where IBAN is used
-
Europe
-
Middle East
-
Parts of the Caribbean
❌ Not used in:
-
United States
-
Canada
-
China
-
Australia
Structure (example: UK IBAN)
-
GB → Country
-
29 → Check digits (anti-typo protection)
-
NWBK → Bank code
-
601613 → Branch
-
31926819 → Account number
📌 Length varies by country (up to 34 characters).
Why banks love IBAN
-
Fewer errors
-
Faster processing
-
Lower fees
In Europe, no IBAN = guaranteed delay.
03️⃣ ABA Number
The “Routing Number” Inside the United States
What it is (plain English)
The ABA Number is America’s internal banking routing code.
It’s only for:
-
U.S. domestic clearing
-
Final settlement inside the U.S.
Think of it as:
📍 A local sorting code inside America.
Structure
A simple 9-digit number:
-
First 8 digits → bank & region
-
Last digit → error check
You’ll see it:
-
on U.S. checks
-
in ACH transfers
-
in domestic wire transfers
Important rule (many people miss this)
❌ ABA cannot replace SWIFT
✅ For international → U.S. transfers, you usually need both.

05️⃣ Practical Remittance Guide (Real-Life Logic)
Think of it like sending a package
Sending money to Germany
-
SWIFT → Germany’s banking city
-
IBAN → recipient’s exact address
Sending money to New York
-
SWIFT → enters the U.S. banking system
-
ABA → routes inside the U.S.
-
Account number → final delivery
Which codes do you need?
✔ Europe / Middle East
→ SWIFT + IBAN
✔ United States
→ SWIFT + ABA + Account Number

→ SWIFT + Account Number
How to find the correct codes
-
Ask the recipient directly (best option)
-
Check bank statements or online banking
-
Bank’s official website
-
Use reputable lookup tools only
Common myths (and fixes)
❌ “IBAN works everywhere”
✔ Only in IBAN-adopting countries
❌ “ABA is enough for international transfers”
✔ ABA is domestic only
Final Reality Check (Please Don’t Skip)
One wrong digit can cost days—or real money.
Before clicking “Send”:
-
double-check codes
-
confirm names
-
confirm account numbers
Banks don’t forgive typos.
They just charge fees.
