IBAN vs. QR-IBAN: Which Number Goes on Your Swiss Invoice?

At first glance, IBAN and QR-IBAN differ by only two letters — but in practice, they determine whether a payment is processed smoothly or disappears into thin air. Many SMEs and freelancers use the wrong number because they don't know when each applies. This article clears up the confusion.
What is the classical IBAN?
The IBAN (International Bank Account Number) has been the standard in European payment traffic for decades. In Switzerland, it always starts with "CH", followed by two check digits and 17 alphanumeric characters — a total of 21 characters.
Example: CH56 0483 5012 3456 7800 9
The IBAN uniquely identifies a bank account. It is used for:
- Account transfers within Switzerland and abroad
- Payment orders without a structured reference code (SCOR or QRR)
- Salary payments, expense reimbursements, supplier invoices without a QR-code
- International transfers (IBAN is the only option there)
Important: The classical IBAN cannot be embedded in the payment section of a QR-bill if a QR-reference (QRR) is to be used.
What is a QR-IBAN?
The QR-IBAN is an account number specifically introduced for the Swiss QR payment standard. It also begins with "CH" and has the same length as the classical IBAN (21 characters), but differs through the IID (Institution Identification) in positions 5–9: for a QR-IBAN, this value lies between 30000 and 31999.
Example: CH44 3199 9123 0008 8901 7
The QR-IBAN was introduced so that banks and processing systems can automatically recognise whether a payment contains a QR-reference (QRR). This reference — a 27-digit number — enables automated posting and is the direct successor to the orange payment slip.
The crucial rule: Which comes when?
| Situation | Account Number | Reference Type |
|---|---|---|
| QR-bill with structured reference | QR-IBAN | QR-reference (QRR) |
| QR-bill without structured reference | IBAN | SCOR or "None" |
| Standard transfer / International transfer | IBAN | — |
| eBill | IBAN | — |
The combination QR-IBAN + SCOR is not permitted. Neither is IBAN + QRR. Anyone using these combinations on an invoice risks rejection by the banking system or incorrect posting of the payment.
How do I know if I have a QR-IBAN?
The simplest method: check your online banking. Most Swiss banks explicitly display a "QR-IBAN" under the account details once you set up QR-bills. If your account does not have a QR-IBAN, you cannot use QR-references — then you must use the IBAN on the QR-bill together with a SCOR reference or without a reference.
Alternatively, you can check the IID of your account: identify the digits at position 5–9 in the IBAN. If the value lies between 30000 and 31999, it is a QR-IBAN.
Common mistakes in practice
Mistake 1: IBAN instead of QR-IBAN on QR-bill with QRR This is the most frequent error. The result: the bank cannot assign the QR-reference, the payment is not automatically posted, or it is rejected.
Mistake 2: QR-IBAN for international transfers A QR-IBAN is a purely Swiss construct. For payments abroad, only the classical IBAN is valid. If you give a foreign customer the QR-IBAN, the payment cannot be processed.
Mistake 3: Wrong IBAN in the QR-code, correct one in the invoice header If you create invoices manually or adapt a template, the QR-code may contain a different IBAN than the visible text. The QR-code takes precedence in the processing — the error is then invisible until a payment lands on the wrong account. The article QR-Bill: 7 Mandatory Field Errors That Delay Payment lists further such pitfalls.
Mistake 4: No reference despite QR-IBAN If you use a QR-IBAN, you should always use a QRR. Although "No reference" is technically permitted, you then lose the main advantage of the QR-IBAN — automatic posting based on the reference number.
QR-IBAN and VAT: What to note
The choice between IBAN and QR-IBAN has no direct impact on VAT treatment. However: if you issue invoices as a VAT-liable person — that is, with annual turnover over CHF 100,000 — you must ensure that the invoice mandatory fields are correct. Errors in the payment section (wrong IBAN type) can lead to invoice rejection by the customer, causing payment delays. An overview of all current VAT rates and obligations can be found in Swiss VAT basics 2026 — rates, duties and special rules.
Correct use in invoicing software
Anyone who creates invoices digitally should enter the account details correctly once and for all. Many problems arise because the account was originally entered with the classical IBAN and QR-bills were subsequently activated — without switching the account number to QR-IBAN. The complete process for creating a compliant QR-bill is described in the guide Create a Swiss QR-bill — step-by-step guide.
If you want to set up a new invoice directly with correct bank details, you can do so with the SnapBill app, which clearly separates IBAN and QR-IBAN.
SnapBill as a Swiss online invoice generator automatically generates the QR-code based on the stored account type — the mix-up never happens in the first place.
At a glance
- IBAN: for standard transfers, international payments, eBill; combined with SCOR or without reference on QR-bill.
- QR-IBAN: exclusively for QR-bills with QR-reference (QRR); IID lies between 30000 and 31999.
- The combination QR-IBAN + SCOR or IBAN + QRR is invalid and leads to processing errors.
- QR-IBANs are not suitable for international transfers — the classical IBAN always applies there.
- Enter account details in invoicing software once correctly and be sure to switch to QR-IBAN when activating QR-bills.
Frequently asked
How do I request a QR-IBAN from my Swiss bank?
A QR-IBAN is automatically assigned by the bank when you set up or activate an account for using QR-bills. There is no separate application: you contact your bank or activate QR-bills in online banking, after which the QR-IBAN appears in the account data section. Costs vary depending on the bank service provider.
Can I provide both IBAN and QR-IBAN on one invoice?
No. The payment section of a QR-bill provides for exactly one account element — either the IBAN or the QR-IBAN, depending on the reference type chosen. Two account numbers side by side are not technically provided for and would cause the QR-code validation to fail.
What happens if a customer pays despite the wrong IBAN?
If the QR-code contains an incorrectly used account number (e.g. IBAN instead of QR-IBAN with a QRR), the payment may be rejected or land on an account that is not assigned to active accounts receivable. At best, it appears as an unidentifiable payment; at worst, it must be manually tracked down.
Does the QR-IBAN also apply for payments from Germany or Austria?
No. The QR-IBAN is a purely Swiss standard and is not recognised by foreign banking systems. For invoices to customers in Germany, Austria, or other countries, you must always provide the classical IBAN. For international payments of larger amounts, a SWIFT/BIC code is often also required.
How do I recognise on a received invoice whether the details are correct?
Check positions 5–9 of the printed account number: if the value lies between 30000 and 31999, it is a QR-IBAN — then a 27-digit QR-reference must also be present. If another number is there, it is a classical IBAN that must not contain a QRR. Many online banking applications perform this check automatically when reading the QR-code.
