Understanding ISO 20022 Structured Address Requirements
The payments industry is moving toward richer, more structured data under the global ISO 20022 standard. One of the key changes is the requirement for structured address information in payment messages.
From 15th November 2026, structured addresses will become mandatory across many payment schemes. This means organisations must ensure their address data is complete, standardised, and captured in clearly defined fields rather than free text.
For many businesses, this represents a significant data‑quality and system‑readiness challenge. However, tools such as GeoDirectory’s comprehensive Irish address database can greatly simplify the transition and help ensure compliance well ahead of the deadline
1. What is ISO 20022?
ISO 20022 is a global financial messaging standard being adopted across the payments industry.
It provides richer, more structured data to make payments faster, more secure, and more accurate.
As part of this standard, structured addresses are now required for many domestic and cross‑border payment messages.
2. What is a Structured Address?
A structured address means entering address information in clearly defined, separate fields instead of one free‑text line.
A structured address typically includes:
-
Street name
-
Building number
-
Town / City
-
Postcode / Eircode
-
Country
Example
Before (Unstructured):
“23 Greenfield Court, Dublin 12, Ireland”
After (Structured):
-
Street Name: Greenfield Court
-
Building Number: 23
-
Town/City: Dublin
-
Postcode: D12 ABC1
-
Country: IE
3. Why This Change Matters
ISO 20022 improves payment processing in several ways:
-
Fewer payment delays
Clear, structured data reduces manual reviews and repairs.
-
Better compliance and fraud detection
Regulators require more precise data for AML and sanctions screening.
-
Improved automation
Banks and payment systems can process structured data more efficiently.
-
Future‑proofing
Structured address formats support new payment services and emerging digital standards.
4. What do Customers Need to do?
You may need to update how you store or submit address information in your systems.
Action Steps
-
Ensure each address record includes all mandatory fields (street, number, town/city, postcode, country).
-
Remove any “all‑in‑one” address free‑text lines.
-
Update your internal systems, templates, or file formats if needed.
-
If submitting bulk files (e.g., XML or CSV), ensure they follow ISO 20022 structured elements.
If you use a third‑party tool or platform, check with your provider for required changes.
5. What Happens If Addresses Are Not Structured?
Depending on the bank or scheme:
-
Payments may be delayed
-
Payments may be rejected
-
Additional queries or compliance checks may be required
-
Screening may be inaccurate or incomplete
Structured addresses help avoid these issues.
6. When Do Customers Need to Be Ready?
The ISO 20022 Structured Address Requirement becomes mandatory on 15th November 2026.
From this date onward, banks and payment processors will increasingly reject or delay payments that do not include full structured address data.
