How to Send an International Wire Through the SWIFT Network

UpdatedAugust 11, 2026

Send USD or foreign-currency wires to payees in most countries through Relay's SWIFT connection, typically arriving in 2 to 3 business days.

What you need before you start

Have this ready before you open the payment flow:

  • International wires enabled on your Relay account. Sending is enabled the first time you accept the international payments terms; receiving requires a separate application under Settings → International Wires Activation

  • The payee's legal name and physical address (PO Boxes are not accepted)

  • The payee's SWIFT/BIC code, plus an IBAN or local account number if the destination country requires one

  • Any destination-specific fields the country requires (BSB for Australia, CNAPS for CNY wires to China, Purpose of Payment code for the UAE, and so on)

  • Enough balance in the paying account to cover the wire amount plus the plan-based SWIFT fee

  • Access to the mobile phone tied to your 2FA, in case you are prompted to verify the payment with an SMS code

If the wire is in a currency other than USD, plan the send inside the FX conversion window: Monday to Friday, 7:00am to 6:00pm ET. USD-denominated SWIFT wires can be initiated outside that window.

Intermediary banks in the SWIFT chain may also deduct their own fees from the wire amount before it reaches the payee's account. Relay does not control what intermediary banks charge.

How long does a SWIFT wire take to arrive?

SWIFT wires are typically sent out within 2 to 3 business days of you submitting the payment. Total delivery time depends on the payee's bank and any intermediary banks that route the funds along the way.

What are the daily and monthly international wire limits?

Accounts have per-day and per-month limits on outbound international wires. Exact limits vary by plan, account age, and verification status. You can view your current limits in your Relay account under Settings → Account Limits.

What information do I need for specific countries?

Some destinations require extra fields on top of the SWIFT/BIC code.

  • Australia (AUD): Include the payee's BSB (Bank State Branch) number, and add the account number to the memo in the format FBO [account number]

  • China (CNY): A CNAPS number is required for wires to Chinese bank accounts in CNY

  • United Arab Emirates: A Purpose of Payment (PoP) code is required on the wire

  • European Union and most of continental Europe: An IBAN is required in addition to the SWIFT/BIC

  • United Kingdom: An IBAN is required; a sort code may also be requested

For any country not listed here, ask the payee's bank which fields they require.

What is a SWIFT code?

A SWIFT code (also called a BIC, or Bank Identifier Code) is an 8-to-11 character identifier that routes the wire to the payee's specific bank and branch anywhere in the world. The payee's bank supplies the code.

What is an IBAN?

An International Bank Account Number (IBAN) is a standardized account identifier of up to 34 alphanumeric characters used in many countries to route international wires. IBANs are required for wires to most European countries and several markets in the Middle East.

How do I pay a bill through the international wire flow?

If you already have the bill file, start the wire from Bill Pay and let Relay pre-fill the payment details.

  1. Sign in to your Relay account

  2. Click Payments and select the international wire payment method

  3. Under Have a bill handy?, upload the bill file

  4. Relay auto-extracts the vendor name, invoice number, line items, and dates

  5. Review or edit any fields, and complete the memo

  6. Optional: add accounting categorization

  7. Click Next Step

  8. Verify the details and select Pay

Common issues

  • Wire not received after 3 business days: Confirm the SWIFT/BIC and IBAN you entered match what the payee's bank has on file. Ask the payee whether their bank is holding the wire for compliance review.

  • FX rate expired or not showing: Non-USD conversions run Monday to Friday, 7:00am to 6:00pm ET. Retry inside that window for foreign-currency sends.

  • "Additional information required" error at review: The destination country needs an extra field (BSB, CNAPS, PoP code, IBAN). Add the field and resubmit.

  • SMS 2FA code not arriving: Check the phone number on file under Settings, and confirm your device has signal. Retry the send, and contact Customer Experience if the code still does not arrive.

  • Wire returned or bounced: The receiving bank or an intermediary can return a wire for missing information, sanctions review, or a closed payee account. Contact Customer Experience with the payment reference number so we can trace it.
