Swift has postponed, Switzerland has not: the ISO 20022 structured address deadline stands
If you followed payment news this summer, you may have seen the headline: Swift has delayed the ISO 20022 structured address deadline. It is tempting to conclude that the pressure is off for everyone. For Swiss SMEs, that conclusion would be wrong. The ISO 20022 structured address in Switzerland remains mandatory from 14 November 2026, exactly as planned.
The Payments Committee Switzerland (PaCoS) has confirmed that the Swiss timeline does not move. In other words, the international network got more time, but the payment files your accounting and payroll software send to your Swiss bank did not. With the deadline now only weeks away, this article explains what changed, what did not, and what you should still check.
What exactly did Swift and the EPC postpone?
Swift (for cross-border payments) and the European Payments Council (for SEPA) had both planned to make structured or hybrid addresses mandatory from November 2026. During summer 2026, at the request of market participants, both bodies suspended that deadline. On 27 August 2026, Swift announced that it would defer all payments changes in its 2026 Standards Release and set a new timing for structured addresses by December 2026 at the latest. The non-payment changes (securities, trackers, exceptions and investigations) are now scheduled for 12 June 2027.
The reason is telling. In its announcement, Swift notes that progress remained uneven, with large parts of the industry in all regions still unable to meet the requirement. Several communities formally asked for more time. As a result, unstructured addresses can continue to circulate in the Swift network for the time being.
Why the ISO 20022 structured address in Switzerland is still due on 14 November 2026
Switzerland is in a different position. Structured and hybrid addresses are already largely established in Swiss and Liechtenstein payment traffic, so PaCoS decided that no change to the introduction date was needed. SIX, which publishes the Swiss Payment Standards, states that the SPS 2026 implementation guidelines and the QR-bill guidelines version 2.4, both valid from 14 November 2026, remain unchanged and in force.
Concretely, from that date, under the Swiss Payment Standards:
- every address in a payment order must be structured or hybrid, for all payment types (domestic, SEPA and cross-border);
- the town and the country must always be filled in as separate fields whenever an address is provided;
- the parallel phase for the old message versions ends: payment orders must use pain.001.001.09 and cash management messages camt.05x.001.08;
- a payment with an unstructured address must carry a requested execution date before 14 November 2026, otherwise it can no longer be processed.
The detail that fuels the confusion: the SIC release of 13 November
There is one nuance worth knowing, because it is already being misread. The SIC release of 13 November 2026, which concerns interbank clearing, will go ahead with an adjusted scope. In its release notes (version 1.3 of 21 September 2026), SIX states that the change request discontinuing the unstructured address in SIC will not be put into force, so as not to hinder payments to and from the Swift network. According to SIX, payment messages with unstructured addresses may therefore still be received in interbank traffic.
This is a technical tolerance between banks, not a postponement for your business. The rules that govern the files you send to your bank are the Swiss Payment Standards, and they have not moved. SIX also notes that individual banks may offer options outside the standards as a customer service, which can include the unstructured address. Some may be more tolerant than others, but you cannot plan your payment runs on that assumption without written confirmation from your bank.
This article provides general information on a banking standard, not individual advice. Requirements and cut-off dates may vary by bank: confirm the details with your own institution.
Swift delay or Swiss deadline: who is affected by what?
For a typical Swiss SME, the practical picture looks like this:
- Supplier and salary payments sent from your software to a Swiss bank: Swiss rules apply. Structured addresses and pain.001.001.09 are required from 14 November 2026.
- QR-bills you issue to customers: only structured addresses have been allowed since November 2025. UBS states that QR-bills with unstructured addresses could only be accepted for payment until 30 September 2026, a date that has now passed. If your invoices still show combined addresses, fix this now.
- Standing orders and e-banking templates: according to SIX, financial institutions must ensure they are adjusted by 13 November 2026 at the latest. Follow your bank's instructions and stop reusing old templates.
- LSV+ and BDD direct debits: no change is planned until their discontinuation at the end of September 2028.
- Payments relayed abroad via Swift: the international deadline is suspended, but your order to a Swiss bank still has to meet Swiss rules first.
Your ISO 20022 structured address checklist for the last weeks
We covered the fundamentals in our earlier guide to the ISO 20022 deadline of November 2026. Here is the short list of what to verify now, in order of priority:
- Ask your bank in writing for its exact cut-off date and whether it will accept anything beyond the Swiss Payment Standards.
- Confirm with your software provider that your accounting and payroll software exports pain.001.001.09, not the older 2009 version.
- Clean your supplier and employee master data: street, number, postal code, town and country, each in its own field. Town and country are the minimum.
- Check that the QR-bills you send carry structured addresses only.
- Review standing orders and replace any old e-banking templates.
- Schedule any last payment runs with unstructured data before 14 November, or better, stop relying on them altogether.
- Run a test batch and a test statement import (camt.053) with your bank before the deadline.
How Odoo handles structured addresses and pain.001
In Odoo, contact addresses are stored in separate fields by design (street, ZIP, city, country), which makes structured addresses easier to produce than in tools based on free-text address blocks. The risk lies in the data itself: imported contacts with the full address in the street line, missing countries, or a town typed into the wrong field. A simple filter on contacts without a country or city usually reveals most problem records in minutes.
Also check which ISO 20022 version your Odoo database exports for Swiss payments, and test a file with your bank. As an official Odoo partner in Geneva, we see that the remaining work is rarely technical: it is mostly data hygiene. The same logic applies to the rest of your finance flows, as described in our article on supplier invoice management with Odoo.
Frequently asked questions about the Swift delay and the Swiss deadline
Does the Swift delay postpone the ISO 20022 deadline in Switzerland?
No. PaCoS decided to keep 14 November 2026 for the Swiss Payment Standards and the QR-bill. The Swift and EPC suspension concerns the international and SEPA networks.
What is the minimum required for a structured address?
Whenever an address is given, the town and the country must be provided as separate data elements. Street, building number and postal code should also sit in their own fields.
Which file format must my software produce from 14 November 2026?
Payment orders in pain.001.001.09 (ISO 20022 version 2019). Support for the older pain.001.001.03 ends with the parallel phase.
