If your bank is international (based outside the U.S.), you'll have to use a SWIFT code for your transfer. If it is U.S.-based, you will use the wire routing number (also known as the ABA routing number) for your transfer.

A SWIFT code, also known as a Bank Identifier Code (BIC), is an 8–11 character code that identifies a bank or financial institution's country, location, branch, and title. The code is formatted as "AAAABBCCDDD", with each section of characters representing a different part of the bank's location:

AAAA: The bank code, which is usually a shortened version of the bank's name.

BB: The country code.

CC: The location code, which can be letters or numbers and indicates the bank's headquarters.

DDD: The branch code, which can be letters or numbers and indicates a specific branch. If the code is for the bank's main office, use "XXX". 

ABA routing numbers are sometimes called transit numbers and can be found at the bottom left corner of a check. You can also check with your bank online or in person to confirm the number.

An ABA wire routing number is usually nine digits long and can be printed as either 021200025 or 0212-0002.

Note; SWIFT deposits and withdrawals are temporarily not supported by Gemini's banking partners for AUD. Gemini can accept deposits of AUD via BECS/NPP transfers.

Note; Gemini recently updated our AUD deposit and withdrawal process and no longer supports SWIFT transfers for AUD. Since we only collect SWIFT information when AUD payment methods are added — but BSB details are required to process BECS or NPP withdrawals — withdrawal attempts will fail. If you're trying to withdraw AUD, please contact our customer support team so we can help process the withdrawal manually on your behalf. This is a temporary measure while we work on a long-term solution.

Note; SWIFT deposits are temporarily not supported by Gemini's banking partners for EUR. Gemini can accept deposits of EUR via SEPA/Target2 transfer.
