When sending money to Germany via remittance, you must provide a critical piece of information: the IBAN. This is a 22-character alphanumeric international standard number. Germany’s IBAN follows a clear format, as shown below:
DE89 3704 0044 0532 0130 00
This standardized number reduces transfer errors, ensuring funds reach the designated account accurately and efficiently. Properly understanding and using the IBAN is a vital step to ensuring worry-free international transfers.

To complete a transfer accurately, you first need to understand the internal structure of the German IBAN. It’s not just a random string of digits but a meticulously designed format adhering to international standards.
IBAN stands for “International Bank Account Number.” According to the International Organization for Standardization (ISO 13616), it is an alphanumeric string used globally to uniquely identify a specific bank account. This standardized system is widely used in European countries like Germany, France, and Italy, as well as increasingly adopted by non-European countries like Brazil and Saudi Arabia, aimed at simplifying and securing cross-border payments.
While the overall IBAN structure is uniform, its length varies by country. For example, Germany’s IBAN is 22 characters, while France and Italy’s are 27 characters.
The German IBAN consists of 22 characters, each part carrying a specific meaning. You can refer to this table to understand its components:
| Component | Length | Example (DE89 3704 0044 0532 0130 00) | Meaning |
|---|---|---|---|
| Country Code | 2 letters | DE | Identifies the country of the bank, with DE representing Germany. |
| Check Digits | 2 digits | 89 | Generated via the MOD-97 algorithm to verify the accuracy of the entire IBAN, preventing input errors. |
| Bank Code (BLZ) | 8 digits | 37040044 | Uniquely identifies a specific bank in Germany, akin to the bank’s “ID number.” |
| Bank Account Number (Kontonummer) | 10 digits | 0532013000 | Identifies the recipient’s specific account at the bank. |
You might wonder whether the IBAN replaces traditional bank account numbers. In fact, the IBAN doesn’t replace them but encapsulates them into an international format. It integrates Germany’s domestic bank code (Bankleitzahl) and bank account number (Kontonummer) into a standardized format.
Since the full implementation of the Single Euro Payments Area (SEPA) in 2014, the IBAN has become the mandatory standard for all bank transfers in Germany (both domestic and cross-border). While traditional account details remain core components of the IBAN, you only need to provide the full 22-character IBAN when filling out transfer forms, without separately listing the bank code and account number.

An accurate IBAN is the cornerstone of a successful transfer. Before initiating a transfer, you must ensure you’ve obtained the correct number and verified it.
If your German friend or business partner needs to provide you with their IBAN, they can find it through these simple methods:
After receiving the IBAN, spending a minute to verify it is crucial. This helps you catch potential input errors before sending. You don’t need to manually calculate the check digits, as many online tools can do this for you.
Recommended Tools: Websites like Wise or IBAN.com offer free IBAN validators. Simply copy and paste the IBAN, and the system will automatically check the country code, length, format, and internal check digits for validity. These tools instantly tell you if the IBAN structure is correct.
A single small error can lead to transfer delays, returns, or even funds being sent to the wrong account. Up to 8% of international payment failures stem from incorrect account information. Be sure to avoid these common mistakes:
Best Practice: Copy and Verify The safest method is to copy the IBAN directly from official documents provided by the recipient (e.g., email or instant message) and paste it into the transfer platform’s field. After pasting, double-check each character to ensure complete accuracy.
Mastering the IBAN’s structure and verification methods brings you closer to a successful transfer. Next, we share practical tips to handle key transfer details, truly ensuring international transfers are worry-free.
When filling out an international transfer form, you’ll notice that in addition to the IBAN, a SWIFT or BIC code is often required. What’s their relationship?
Simply put, they are a golden duo for international transfers, each playing an indispensable role:
The SWIFT/BIC code consists of 8 to 11 characters, including the bank name, country (e.g., Germany is DE), city, and branch information. It acts as a security guard, ensuring your funds are sent to the correct financial institution.
A Simple Analogy
- SWIFT/BIC Code = Bank’s address (e.g.,
DEUTDEFFfor Deutsche Bank in Germany)- IBAN = Your friend’s specific account at that bank (e.g.,
DE89...00)You need both pieces of information for the banking system to first locate the correct “building” (bank) and then the correct “room” (account).
Even for euro transfers within the Single Euro Payments Area (SEPA), many banks, especially for international SEPA transactions, still require the BIC code. Therefore, to ensure worry-free international transfers, it’s best to obtain both the IBAN and SWIFT/BIC code from the recipient.
When you’re ready with all the information and log into your Hong Kong bank account to proceed, accurately filling out the transfer form is the final hurdle to ensuring worry-free international transfers. Here’s a clear guide:
