Netherlands Address Generator

Generate Netherlands address samples with a synthetic street and house-number suffix, city, province and a spaced alphanumeric postcode. Use the Arnhem, Amsterdam, Utrecht, Rotterdam and Den Haag fixtures to test address fields, copying, local saves and CSV/JSON imports without using customer data. These records do not establish deliverability.

A Dutch fixture for spaced postcodes and house-number suffixes

Import the postcode with its internal space and keep the synthetic house-number suffix 1-1 in the street. Check that a spreadsheet or parser does not reinterpret the suffix as a date or arithmetic expression.

Current fixture coverage: 4 selectable regions · 5 locality fixtures

Street: Voorbeeldstraat 1-1
City: Arnhem
Region: Gelderland (GE)
Postal code: 6832 AM

Expected full-address output

Voorbeeldstraat 1-1, 6832 AM Arnhem, Netherlands

Download this record: JSON CSV

Preserve both the postcode space and the full house-number suffix as text; stripping punctuation can change a different field from the postal value.

What to check

Keep the four digits and two letters in a single postcode field, with your chosen spacing contract.
Compare the entire 1-1 suffix after save/reopen rather than checking only the leading house number.

A change to catch in a preservation test: `postalCode`

Original value: 6832 AM
Changed value: 6832AM

A preservation test should detect this change. Test intentional normalization against a separate contract.

What this version does not cover

Four provinces, five locality/postcode fixtures. Municipal sources establish locality/postcode examples, not the synthetic street or house suffix. No PO Box or Caribbean mode.

Municipal publications support the locality/postcode pairs, not the generated Voorbeeldstraat or house-number suffix. This is not a building-register match.

Netherlands: Address structure and practical checks

Postal-code handling

The example postcodes contain four digits, a space and two letters. Preserve the space and treat the whole value as text.

Address fields

A Dutch test address keeps house number with the street and retains the paired locality and postcode. Verify that CSV import does not split or alter these fields.

Scope of these samples

These are synthetic format examples, not verified delivery addresses or real identities. A listed region does not mean that every city, street or building there is covered.

Country-specific test checks

Four digits, a space and two letters

Dutch postcodes use four digits and two uppercase letters separated by a space, before the locality. The city/postcode examples Arnhem / 6832 AM and Amsterdam / 1052 MA come from the UPU Netherlands guide. A matching city and postcode do not validate a synthetic street or house number.

Street first, then house number

The generated Voorbeeldstraat line ends with a synthetic number and suffix such as 12-3. Preserve that suffix as text rather than treating the whole value as a number. Province is a separate administrative field; the compact address line uses street, postcode, city and country. It is an application display, not a certified postal label.

A practical export check

Select Noord-Holland and generate an Amsterdam record. Copy the address and the complete record separately; save and export CSV/JSON. Confirm 1052 MA retains its internal space and uppercase letters, and the house suffix survives import. Five city/postcode fixtures across four provinces are maintained; municipal additions provide more field-mapping cases; P.O. boxes, Caribbean territories and live address lookup are outside this release.

Worked example: preserve a house-number suffix

Input: street = Voorbeeldstraat 12-3; postalCode = 1052 MA; city = Amsterdam. Expected preview: Voorbeeldstraat 12-3, 1052 MA Amsterdam, Netherlands. After saving and JSON export/import, compare each field with the input. Fail the check if the suffix becomes 12, the postcode loses its space, or province is inserted into this compact preview. This fixed example illustrates the formatter; randomly generated house numbers will differ.

FAQ

Are all Dutch provinces covered?

No. Four provinces and five locality/postcode pairs are maintained, including municipal-source additions for Utrecht, Rotterdam and Den Haag.

Is the house-number suffix verified?

No. Suffixes are synthetic test values and are not checked against a building register.

Are Dutch PO Boxes or Caribbean addresses supported?

Neither is a dedicated mode here. Do not infer coverage from the Netherlands country label.
