What this UBS IBAN calculator does

If you need to make or receive a transfer involving UBS in Switzerland, this page helps you quickly work with IBAN data. The calculator handles two core tasks:

  • Generate: Build a Swiss IBAN from a clearing number + account number.
  • Validate: Check whether an IBAN passes the official ISO 13616 / MOD-97 check digit rule.

That means you can spot typing mistakes before sending a payment, which is especially useful for payroll, supplier invoices, or recurring international transfers.

Swiss IBAN structure (CH)

A Swiss IBAN has exactly 21 characters and is structured like this:

CHkk bbbbb cccccccccccc

  • CH = country code (Switzerland)
  • kk = two check digits
  • bbbbb = bank clearing / institution identifier (5 digits)
  • cccccccccccc = account part (12 digits in this simplified calculator model)

For UBS examples, you will often see clearing identifiers associated with UBS entities. In this tool, the default clearing value is set to 00230 for convenience, and you can change it as needed.

How to use the calculator

Generate a UBS-style CH IBAN

  1. Enter the 5-digit clearing number.
  2. Enter your account number (up to 12 digits).
  3. Click Generate CH IBAN.

The calculator computes the check digits automatically and returns both compact and spaced IBAN format.

Validate an existing IBAN

  1. Paste the IBAN in the validation field (spaces are okay).
  2. Click Validate IBAN.

You will get an immediate valid/invalid result. For Swiss IBANs, the tool also shows parsed details like country code, check digits, clearing number, and account section.

Why check digits matter

IBAN check digits are designed to detect common input errors—like swapped digits, missing numbers, or accidental typos. A valid check-digit result does not guarantee the account is open or belongs to the intended recipient, but it does confirm that the IBAN is mathematically well-formed.

Common payment mistakes to avoid

  • Using local account format when the bank requires IBAN.
  • Confusing a QR-IBAN with a standard IBAN workflow.
  • Copy/paste errors caused by hidden spaces or punctuation.
  • Sending international transfers without matching beneficiary name and address details.

UBS transfers: practical notes

For domestic Swiss transfers, many systems still reference clearing/account conventions behind the scenes. For cross-border payments, IBAN + BIC/SWIFT details are often required depending on corridor and currency. Always verify final payment instructions directly in UBS e-banking or official bank documents.

FAQ

Is this an official UBS tool?

No. This is an educational calculator and layout replica page. Always confirm critical payment data with official UBS channels.

Can this validate non-Swiss IBANs?

Yes. The MOD-97 validation logic works for IBAN countries generally, and it also checks country-specific length for many common countries.

Does a valid IBAN guarantee successful payment?

No. It only confirms structural validity. Payment success also depends on beneficiary details, account status, compliance checks, and transfer rules.
