Is a BIC Code the Same as a Routing Number? When to Use Each

No, a BIC code is not the same as a routing number. A Business Identifier Code (BIC), often called a SWIFT code, identifies a financial institution across the international SWIFT network. A routing transit number identifies a U.S. bank for domestic payments like direct deposits, ACH transfers, and check clearing. They belong to two different systems, and one cannot stand in for the other.

If you are sending or receiving money inside the United States, you need a routing number. If money is crossing a border, you need a BIC. Some situations, like receiving an international wire into a U.S. account, involve both.

The Core Differences at a Glance

The two codes differ in three ways that matter to you as the sender or recipient.

Format. A BIC is eight or eleven characters and mixes letters and numbers. A routing number is always nine digits, numbers only.

Geographic scope. Routing numbers work only inside the United States. BICs work globally, across more than 200 countries connected to the SWIFT network.¹

Purpose. Routing numbers move money through domestic systems: the Federal Reserve, the Automated Clearing House (ACH) network, Fedwire, and the newer FedNow instant payment service.² BICs move money through the SWIFT messaging network that banks use to talk to each other internationally.

What a BIC Actually Is

A Business Identifier Code is a globally standardized label assigned under ISO 9362 that points to a specific financial institution anywhere in the world. Most people call it a SWIFT code, though that name is a little misleading: not every BIC is actually connected to the SWIFT messaging network.¹

The characters break down like this:

First four characters: the bank or institution code (alphanumeric)
Next two characters: the country code, following the ISO 3166-1 standard (alphabetic)
Next two characters: a location or city code (alphanumeric)
Last three characters (optional): a branch code that identifies a specific office or department

An eight-character BIC points to the institution’s headquarters. When the three-character branch code is added, the eleven-character version identifies a specific branch or unit.¹

There are also two categories worth knowing. A connected BIC belongs to an institution that can actually send and receive messages over SWIFT; this is the type used for international wire transfers. A non-connected BIC exists only for identification and carries no authorization to exchange SWIFT messages.¹ For an international transfer, you need the recipient bank’s connected BIC.

What a Routing Number Actually Is

A routing transit number (RTN) is a nine-digit code that identifies a U.S. bank or credit union for domestic payment processing. The American Bankers Association introduced the system over a century ago, and it remains the backbone of check clearing, direct deposits, and electronic transfers within the country.

The nine digits are structured:

First four digits: the Federal Reserve routing symbol, which identifies the Federal Reserve district and the type of institution
Next four digits: the ABA institution identifier, which pinpoints the specific bank
Last digit: a check digit calculated through a formula that catches typos and data-entry errors

A single bank often uses different routing numbers for different transaction types. The number for paper checks may not be the same one used for ACH or wire transfers, so confirm which routing number applies before you set up a new payment.

On a paper check, the routing number appears in two places. The nine-digit version is printed in magnetic ink along the bottom left, where machines can read it automatically. A second version, called the fractional routing number, appears in the upper right corner as a fraction; its denominator corresponds to the Federal Reserve routing symbol from the first four digits of the nine-digit code.³ For modern transactions, the nine-digit version at the bottom is the one you use.

Which Code You Need for Your Transaction

Staying Inside the United States

Any payment that stays in the U.S. runs on routing numbers. That covers:

Direct deposit of paychecks or tax refunds
ACH payments, including recurring bill payments, subscription charges, and bank-to-bank transfers
Paper check deposits and clearing
Domestic wire transfers through Fedwire
Instant payments through FedNow, which identifies participating banks by their routing transit numbers²

Domestic ACH transfers are usually free or cost only a few dollars. A BIC has no role in any of these.

Sending Money Across a Border

Cross-border transfers use the SWIFT network and require the receiving bank’s BIC. Fees are meaningfully higher than for domestic transfers; most U.S. banks charge somewhere between $30 and $75 for an outgoing international wire, and incoming international wires often carry fees too.

International transfers can also pass through intermediary (correspondent) banks when the sending and receiving banks have no direct relationship on SWIFT. Each intermediary uses BICs to identify the next bank in the chain, and each one may deduct its own processing charge along the way. A transfer routed through two intermediaries could lose $30 to $60 in fees before it reaches the recipient, on top of what the sending and receiving banks charge.

Receiving an International Wire at a U.S. Bank

This is the case where both codes come into play. A sender abroad generally needs your U.S. bank’s BIC to route the transfer through the international network. Depending on the bank, the sender may also need your account number and, in some cases, your bank’s routing number. Your bank’s website or customer service line can confirm exactly what to share.

A Note on IBANs

Many countries, particularly in Europe, the Middle East, and parts of Africa and Latin America, also require an International Bank Account Number (IBAN) for incoming transfers. An IBAN follows the ISO 13616 standard and embeds a country code, check digits, and a bank identifier related to the BIC standard.⁴ When sending to an IBAN country, you typically provide both the recipient’s IBAN and the receiving bank’s BIC. The United States does not use the IBAN system, so you will not have one for a U.S. account.

How to Find Each Code

Your Routing Number

The fastest place to look is the bottom left corner of a personal check. The nine-digit routing number appears first, followed by your account number and the check number. If you do not have checks, the routing number is usually shown in your account details online, in the wire transfer section of your bank’s website, or in the mobile app. Customer service can also provide it.

Because a single bank can use different routing numbers for paper checks, ACH, and wires, ask specifically for the one that fits the transaction you are setting up.

Your Bank’s BIC

Your BIC (SWIFT code) usually appears on your account statement, in the international or wire transfer section of your bank’s website, or in your online banking portal. Customer service can provide it if you cannot find it, and the SWIFT directory is searchable online by bank name and location.

Codes for Digital Wallets and Payment Apps

Payment apps that connect to a U.S. bank account use routing numbers, not BICs. For Apple Cash, you can view or update the linked bank routing and account numbers by tapping your Apple Cash card in the Wallet app, selecting card details, and scrolling to the bank account section.⁵ Venmo, Zelle, PayPal, and similar services likewise ask for a routing number when you connect a U.S. bank account.
