When making international transfers, you need to accurately obtain the U.S. bank routing number. You can use multiple methods to find and verify it to ensure accuracy and avoid transfer failures. Below are three commonly used methods in detail.
You can directly obtain the U.S. bank routing number from a check. The steps are as follows:
Tip: The U.S. bank routing number on a check is usually very accurate, but you should still verify it to avoid transfer delays due to number changes.
You can follow the same method to find the routing number on checks for USD accounts issued by licensed Hong Kong banks. Even if the check comes from a different bank, the number format is generally consistent.
If you don’t have a check, you can obtain the U.S. bank routing number through online banking. The process is as follows:
U.S. banks regularly update routing number information in their online banking systems to ensure data accuracy. Large banks may update multiple times a week to ensure smooth ACH payments and international transfers. When using online banking services from licensed Hong Kong banks in China/Mainland China, you can find the routing number for USD accounts in a similar way.
Note: Even if you find the routing number through online banking, it’s recommended to verify it again before an international transfer to avoid discrepancies due to system updates.
If you have doubts about the check or online banking information, you can directly contact bank customer service. You can inquire via phone, online customer service, or by visiting a bank branch. Customer service representatives will provide the latest U.S. bank routing number based on your account information.
The table below summarizes common official verification channels:
| Source | Description |
|---|---|
| Moneycorp | Provides FAQs on ABA routing numbers, recommending verification through bank websites or customer service for the latest information. |
| Wise | Emphasizes verifying routing numbers before international transfers to ensure secure and fast processing. |
| Western Union | Offers methods to find ABA numbers, including asking the recipient, contacting the bank, or checking the bank’s website. |
When conducting international transfers through licensed Hong Kong banks in China/Mainland China, you can also call the bank’s customer service hotline to obtain the most authoritative U.S. bank routing number information.
Reminder: U.S. bank routing numbers may change due to bank mergers or system upgrades. You should regularly check bank announcements or proactively inquire to ensure you have the latest information.
Using these three methods, you can efficiently and accurately obtain the U.S. bank routing number. Before an international transfer, always verify all information to avoid delays or losses due to incorrect numbers.

When conducting international transfers through licensed Hong Kong banks in China/Mainland China, entering the U.S. bank routing number is a critical step. The U.S. bank routing number (ABA number) is used to identify U.S. banks, ensuring funds are accurately transferred to the target bank. You need to provide the U.S. bank routing number in the following scenarios:
When filling out international transfer information, it’s recommended to follow the bank’s provided form or online page and enter each item carefully. You typically need to input the recipient bank’s routing number, SWIFT code, recipient’s name, account number, and recipient bank address. You should carefully verify each item to ensure accuracy.
Tip: If you’re unsure about the U.S. bank routing number, verify it through online banking, checks, or bank customer service to avoid transfer delays due to incorrect numbers.
When making international transfers, in addition to the U.S. bank routing number, you’ll encounter SWIFT codes and IBAN. The three differ significantly in purpose and entry methods. The table below helps you quickly understand:
| Type | Purpose | Description |
|---|---|---|
| Routing Number | Domestic Transfers | Used for U.S. domestic transfers, a nine-digit identifier. |
| SWIFT Code | International Transfers | Identifies the receiving bank to ensure accurate international payments. |
| IBAN | International Transfers | Identifies specific bank accounts, with formats varying by country. |
When filling out international transfer forms, you typically need to provide the SWIFT code and IBAN. The SWIFT code consists of 8 to 11 characters, identifying a specific bank and branch. The IBAN can include up to 34 characters, comprising the country code, check digits, bank code, and account number. The SWIFT code ensures funds reach the correct bank, while the IBAN ensures funds go to the correct account. If the recipient bank is in the U.S., you usually only need the routing number and SWIFT code; if it’s in Europe or other regions, you may need to provide the IBAN.
You should choose the correct entry method based on the recipient bank’s country and requirements.
Before submitting an international transfer request, you must verify all information. Banks recommend focusing on the following:
If the submitted information is incomplete or incorrect, the bank may reject the transfer. Common reasons include errors in beneficiary information, such as misspellings in the account number or SWIFT code. For large transfer amounts or incomplete information, banks may reject the transfer due to compliance issues. Technical issues or SWIFT network problems may also cause transfer failures.
Reminder: When handling international transfers through licensed Hong Kong banks in China/Mainland China, it’s recommended to prepare all necessary information in advance and verify it through official bank channels to ensure smooth completion.
When entering the U.S. bank routing number, it’s easy to make mistakes with digits or their order. The bank system may fail to identify the recipient bank due to an incorrect routing number, leading to the transfer being returned or delayed. You can take the following steps:
Tip: Verify the routing number before each transfer to avoid changes due to bank mergers or system upgrades.
When handling international transfers in China/Mainland China, incomplete information may lead to the bank rejecting the transfer. Common missing information includes the recipient’s name, account number, SWIFT code, or recipient bank address. You can refer to the table below to prepare all necessary information in advance:

|---|---|
| Routing Number | U.S. bank identifier |

You should follow the bank’s requirements, fill out and verify each item to ensure a smooth transfer.

Tip: Before sending a wire transfer, carefully verify the recipient’s name, address, and bank information. You can contact the recipient’s bank, especially for first-time transfers, to obtain written confirmation to ensure accuracy.
Preparing all information in advance reduces the risk of errors and speeds up the transfer process. Having the recipient bank’s details and transfer purpose helps comply with regulations and enhances transaction speed. The required information includes the recipient’s name and address, transfer amount (USD), recipient bank name and address, bank account number, account type, and SWIFT/BIC code.

When opening accounts at different branches, routing numbers may vary. You should verify the specific routing number for the recipient account’s branch. You can check through checks, online banking, or customer service.
