Merchant onboarding blocked – valid Wise SWIFT/BIC rejected

Hi,

I’m currently blocked at the final stage of Connect IQ merchant onboarding and wanted to check whether others have experienced something similar.

Context:

  • Non-US tax resident
  • Trying to configure USD payout account
  • French IBAN cannot be entered because the account number field only accepts numeric values up to 19 digits
  • I then tried using Wise USD account details instead

The Wise USD account number is accepted, but the SWIFT/BIC is rejected with:

“Swift code has an unsupported format.”

Tested with:

  • TRWIUS35XXX
  • TRWIUS35

Both are valid Wise SWIFT/BIC identifiers.

The onboarding form only requests:

  • account number
  • SWIFT/BIC

I already emailed [email protected] with screenshots and technical details several days ago but have not yet received a reply.

I have already paid the USD 100 merchant registration fee and am now fully blocked at the payout setup step despite being ready to publish paid apps.

Has anyone encountered this before?
Does Garmin merchant onboarding support Wise/Revolut-type institutions, or only traditional banks?

Thanks All.
