🇳🇱 How to Call the Netherlands From the UK (Complete 2026 Guide)

To call the Netherlands from the UK, you need three elements:

1. UK exit code → 00

2. Netherlands country code → 31

3. Dutch phone number (without the leading 0)

✅ The Correct Format

00 31 [Dutch Number Without 0]

Example:

00 31 20 123 4567

☎️ 2. How Dutch Phone Numbers Work

Dutch numbers are typically 9 digits (after removing the leading 0). They fall into two categories:

A. Landline numbers

• Start with 0 followed by an area code

• Area code lengths vary (2–3 digits)

Examples:

• Amsterdam → 020

• Rotterdam → 010

• Utrecht → 030

• The Hague → 070

B. Mobile numbers

• Begin with 06

• When dialling internationally, remove the 0, so 6 becomes the first digit
