Key facts

Concise statements from the verified fields on this page. Missing values stay unavailable — we do not invent statistics.

Netherlands's ISO 3166-1 codes are alpha-2 NL, alpha-3 NLD, and numeric 528. ISO alpha-2 and alpha-3 are different country-code formats.
Netherlands's international telephone calling code is +31.
Netherlands's currency in this dataset is Euro (ISO 4217 EUR, symbol €). A currency symbol does not always uniquely identify a currency — prefer the ISO 4217 code.
The capital listed for Netherlands is Amsterdam.
Netherlands is listed with one primary IANA time zone on this page: Europe/Amsterdam.
Netherlands's postal-code format in this dataset is “####|#### @@”. Postal-code format validation does not confirm that an address exists.
Driving side listed: right.
Measurement system listed: metric.

At a glance

Country-specific notes grounded in the verified fields below.

Single civil zone Europe/Amsterdam with daylight saving under IANA rules.
Euro (EUR / €); postal codes use a letter-number pattern (#### @@).
Native name Nederland; language Dutch (nld). Alias “Holland” is searchable but not equivalent to the full country name.

Currency & languages

Currency ISO 4217: Euro (ISO 4217 EUR) · symbol € · minor units: 2 Tender from the open-dataset snapshot — third-party reference, not live exchange rates. Prefer the ISO 4217 code when a symbol is shared.
Languages (dataset identifiers) ISO 639: Dutch nld Identifiers as recorded in the assembled datasets — not a complete official language schedule.

Time zones

Live local time from IANA identifiers (server/OS tzdata). Offsets can change with daylight saving.

Standards & definitions in use

ISO 3166-1: Country codes: alpha-2, alpha-3, and numeric identifiers as used in our catalog (not a sold ISO product dump).
ISO 4217: Currency codes (and symbols when present). Symbols may be shared across currencies.
ISO 639 (dataset identifiers): Language codes as recorded in the assembled open datasets — not a complete legal language schedule.
International calling codes: Country/territory telephone dialing prefixes (E.164-style +N). Distinct from ISO country codes.
IANA Time Zone Database: Zone identifiers and live offsets via PHP/OS tzdata at request time. Offsets can change with daylight saving.
Area (km²): Land/area figure from the reference snapshot, expressed in square kilometres when present.
Population (estimate): Reference estimate with an effective year when known — not a live census API.

How empty values are labeled

Not available — missing from the verified dataset (not invented).
0 — a recorded zero when the source supplies zero (distinct from missing).
Does not apply — used only when a field is explicitly not applicable (rare).

Data limitations

Not an official ISO, UN, or national-statistics publication.
Population and area are reference estimates with effective year where known.
Postal checker validates format only — not delivery-point existence.
Currency finder does not show live FX rates (see Currency Converter for rates).
Driving side / measurement may be incomplete for some territories.
Administrative divisions are not bulk-published (avoids thin/incomplete geography pages).
Timezone “now” depends on server/OS tzdata freshness.
ODbL sources require attribution and share-alike considerations for redistributed database dumps.

Frequently asked questions

Is Holland the same as the Netherlands?

In casual speech people often say Holland, but the country is the Netherlands. Our catalog keeps “Holland” as an alternate search name pointing to NL.

What is the Netherlands’ currency code?

EUR — euro.

What is the difference between a country calling code and an ISO country code?

A calling code is an international telephone dialing prefix (for example +92). An ISO 3166-1 country code identifies the country in data systems (for example PK, PAK, or 586). They serve different purposes and are not interchangeable.

Does a country always have one time zone?

No. Some countries use a single IANA zone; others span many. This profile lists the zones available in our catalog — use the country time-zones page for live clocks.

Does a valid postal-code format prove that an address exists?

No. Format checks only compare structure to a documented pattern. They do not confirm delivery points or that a code is currently assigned.

Where does this country data come from?

Fields are assembled from maintained open datasets (ISO codes, calling codes, currencies, languages, postal patterns, population/area) plus live IANA time zones via PHP. Editorial notes are written for this profile. Unavailable fields are labeled — we do not invent values.

Are population and area official census figures?

They are reference estimates from the dataset snapshot (year shown when available). For legal or statistical work, confirm with a national statistics office.
