Overview

ISO 3166-3:2020 - "Codes for the representation of names of countries and their subdivisions - Part 3: Code for formerly used names of countries" is the third-edition (2020) ISO standard that specifies guidelines for implementing and maintaining codes for formerly used country names. It covers non-current country names removed from ISO 3166 since the first publication in 1974 and provides a structured, database-oriented approach for traceability of historical country codes.

Key facts:

Edition: Third (2020)

Purpose: Represent deleted/non-current country names

Format: Standard described as a database; codes accessible via ISO’s Online Browsing Platform (OBP)

Encoding: UTF-8 (ISO/IEC 10646)

Key topics and requirements

ISO 3166-3 defines the principles, structure and maintenance rules for formerly used country codes, including:

Principles for inclusion - criteria that qualify a removed country name for listing (see change of country name, division, merger, obsolescence, change of alpha-2 status).

Code elements - use of existing code types (alpha-2, alpha-3, num-3) and a specific alpha-4 construct for formerly used names (original alpha-2 + two letters, with meaning tied to the cause of change).

Periods of validity & traceability - dates for start/end of validity and explicit status of alpha-2 code elements (assigned, unassigned, reserved transitional/exceptional/indeterminate).

Maintenance rules - role of the ISO 3166 Maintenance Agency (ISO 3166/MA), database paradigm for updates, and a decoding table to interpret historical changes.

Data quality - standardized character handling (diacritics checked against ISO/IEC 10646) and consistent use of descriptors rather than column positions.

Applications

ISO 3166-3 provides practical value for any system or workflow that must interpret, store, migrate or display historical geopolitical data:

Archival and historical databases that preserve legacy country identifiers

Government, customs, postal and legal records where historical country status matters

Finance, insurance and trade systems reconciling legacy transaction records

GIS, statistical and demographic datasets requiring consistent historical coding

Libraries, publishers and researchers managing bibliographic and historical references

Software and data integrators implementing backwards-compatible country-code mappings

Using ISO 3166-3 helps ensure consistent, auditable handling of historical country names and supports interoperable, language-independent archival and data-exchange workflows.
