South Africa

South Africa sits at the southern tip of the African continent, bordered by Namibia, Botswana, Zimbabwe, Mozambique, and Eswatini, with Lesotho enclaved within its borders. In international data systems, the United Nations M49 standard assigns it code 710, with ISO alpha-2 code ZA and ISO alpha-3 code ZAF. The UN groups South Africa under the region Africa and the subregion Sub-Saharan Africa; it is a UN member state. The World Bank lists Pretoria as the executive capital, though the nation has three seats of government (Pretoria, Cape Town, and Bloemfontein serve as the administrative, legislative, and judicial centres respectively).

The one fact you cannot get from any other guide: South Africa’s three-capital arrangement is not a constitutional curiosity but a practical administrative split that affects every dataset that records a single capital field, so you must check which capital a source uses before merging files.

Classification facts

These are stable, administrative identifiers. They define how South Africa is coded and grouped in international databases, but they do not describe its government, borders or political status.

• UN M49 code: 710
• ISO alpha-2: ZA
• ISO alpha-3: ZAF
• UN region: Africa
• UN subregion: Sub-Saharan Africa
• UN member state: Yes
• World Bank capital field: Pretoria

The UN M49 classification is a statistical device, not a political or territorial statement. It groups territories for data collection and reporting convenience. The World Bank’s “capital” field is administrative, not a constitutional designation; South Africa has three branches of government seated in different cities. The classification facts above come from the UN M49 documentation and the World Bank country API.

How the three capitals affect your data work

When you merge datasets that include a capital city field, check which capital the source records. The World Bank uses Pretoria. Some other sources use Cape Town or list all three. A mismatch here can break a join or misalign a record, so open the source’s codebook before you merge.

How to verify current facts

South Africa’s inhabitants, languages, currency and economic indicators change regularly. Do not rely on a static figure. For each category below, use the named primary source and note the reference year.

Inhabitants

The World Bank publishes annual inhabitant estimates. Open the World Bank country API, find “South Africa”, and use the indicator SP.POP.TOTL. The reference year will be stated in the API response. Census-based figures may differ from inter-censal estimates.

The UN Population Division also publishes estimates and projections by territory. The two sources may differ by several million because they use different estimation methods and reference dates. For South Africa, the most recent national census (2022) is the primary national source; international agencies then adjust this base with their own estimates. The 2022 census recorded about 62 million people, but UN and World Bank projections may differ by several hundred thousand because they use different post-censal assumptions. For any current figure, state the source, the reference year and the method (census, projection or estimate).

Languages

The Constitution of South Africa (1996, amended) recognises 12 official languages. The national statistical office, Statistics South Africa (Stats SA), publishes language-use data from the census and General Household Survey. Cite the specific census or survey year when quoting percentages.

Currency

The South African rand (ZAR) is issued by the South African Reserve Bank. Check the Bank’s official exchange rate page for current values; do not rely on a static rate. The ISO 4217 currency code is ZAR.

Government and politics

Use the official government portal and the Electoral Commission of South Africa (IEC) for election results and institutional structure. The current president and cabinet composition change; verify before citing. South Africa has nine provinces, each with its own legislature and premier.

Economy

Use the World Bank country API for GDP, income group and development indicators. For GDP, prefer the World Bank’s national accounts data, and always note the reference year. Do not mix nominal and PPP figures in the same comparison.

Travel

Visa and entry rules change frequently. The only reliable sources are the South African Department of Home Affairs and your own government’s travel advisory. The IATA Travel Centre is the industry standard for visa requirements.

Classification identifiers

The table below lists the identifiers used by international statistical systems. These are classification facts, not political or territorial claims. The UN M49 standard assigns numeric codes to territories and areas for statistical convenience; it does not determine sovereignty or borders.

Field	Value
UN M49 code	710
ISO alpha-2	ZA
ISO alpha-3	ZAF
UN region	Africa
UN subregion	Sub-Saharan Africa
UN membership	Member state
World Bank capital field	Pretoria

When classification codes mislead

The UN M49 code and ISO codes are stable, but the regional grouping “Sub-Saharan Africa” is a statistical convenience. It does not imply shared political alignment or development level. When you use this grouping in analysis, state it as a UN statistical region, not as a cultural or political label.

How to verify current data

Official figures are published by Statistics South Africa (Stats SA) and by international agencies. Always record the reference year and the exact definition when citing a number. The World Bank country API returns the country code ZAF, the region and income-level classifications and links to indicator data; the UN M49 documentation is the authority for statistical classification, not for political status.

A checklist before you cite a number

• Name the source (agency and dataset).
• State the reference year.
• State the method (census, projection, estimate, survey).
• Check whether the figure is de facto or de jure.
• Confirm you have not mixed nominal and PPP values in the same comparison.
