Country codes (common)
Common ISO country/region codes used in addresses and identifiers.
How these codes are used on invoices
Country codes (common) is a standardized ISO 3166-1 alpha-2 code list used in structured invoices. Instead of free-text values, buyers, suppliers, ERP systems, and validators expect normalized codes such as DE (Germany), FR (France), IT (Italy). Practical subset; ISO 3166 contains many more codes.
This article treats Country codes (common) as a practical reference, not just a navigation page. It explains the term or workflow in context, shows why it matters for European e-invoicing, and connects the topic to invoice creation, validation, routing, archiving, and ERP implementation decisions.

- Use the exact code from ISO 3166-1 alpha-2 and keep the spelling and casing expected by the standard.

- Validate the final XRechnung, ZUGFeRD/Factur-X, UBL, or CII file before sending it to the recipient.
Frequently asked questions
These are common end-user questions when choosing the right Country codes (common) value for an invoice or ERP export. Frequently asked questions answers the practical questions that usually appear after reading the main explanation of Country codes (common). The answers focus on What is Country codes (common) on an invoice, Which Country codes (common) codes are used most often and Where do I enter a Country codes (common) code in structured e-invoices and are written to clarify implementation choices quickly.
What is Country codes (common) on an invoice?
Country codes (common) is the standardized ISO 3166-1 alpha-2 code list that tells the receiving system which business value was intended. Using the correct code improves interoperability across XRechnung, ZUGFeRD/Factur-X, UBL, CII, and PEPPOL workflows.
Which Country codes (common) codes are used most often?
Common examples on this page include DE (Germany), FR (France), IT (Italy). The right choice depends on your transaction, tax treatment, recipient requirements, and the invoice profile you are sending.
Where do I enter a Country codes (common) code in structured e-invoices?
Enter the code in the structured invoice field that matches its meaning, for example the currency field, VAT category field, payment means field, unit field, or invoice type field. The exact XML path depends on whether you send XRechnung, ZUGFeRD/Factur-X, UBL, or CII.
How do I avoid validation errors with Country codes (common) codes?
Use only values allowed by the relevant implementation guide, keep the code exactly as defined in ISO 3166-1 alpha-2, and provide all related data required by that choice. Many validation errors happen when a code is correct in isolation but inconsistent with the rest of the invoice.
Can I use codes outside this page?
Often yes, but recipients and national profiles frequently accept only a practical subset of the full ISO 3166-1 alpha-2 list. This page focuses on common invoice values, so confirm buyer-specific or country-specific rules before sending production documents.
