If you frequently make international calls or conduct business in Europe, understanding the Netherlands country code and Netherlands phone number format is essential. Whether you’re managing global communications, setting up International Call Forwarding, or using EE International Roaming, having the right dialing information ensures that your calls connect smoothly every time.
This guide covers everything you need to know about the Netherlands country code, Netherlands area codes, and the phone number structure used for both local and international calls.
1. Understanding the Netherlands Country Code
When dialing internationally, every country has a unique prefix known as a country code. For the Netherlands, this code is +31.
1.1 What is the Netherlands Country Code?
The Netherlands country code is used to identify Dutch phone numbers when calling from another country. To place a call to the Netherlands from abroad, simply dial +31, followed by the Netherlands area code and the local phone number.
Example:
+31 20 123 4567
Here:
- +31 = Netherlands country code
- 20 = Amsterdam area code
- 123 4567 = Local phone number
1.2 When to Use the Netherlands Country Code
You’ll need the Netherlands country code whenever you:
- Make an international call to the Netherlands
- Configure International Call Forwarding to a Dutch number
- Register your Dutch business contact number for global communications
2. Netherlands Phone Number Format
The Netherlands phone number format follows a structured and consistent pattern that distinguishes between landline and mobile numbers.
2.1 Standard Netherlands Phone Number Format
A full Dutch number typically consists of 9 digits, excluding the country code. When calling from abroad, you drop the initial 0 that is used in domestic dialing.
Example for Landline:
+31 10 123 4567 (Rotterdam)
Example for Mobile:
+31 6 1234 5678
2.2 Netherlands Phone Number Format Breakdown
- Country Code: +31
- Area Code: 1–3 digits (e.g., 10 for Rotterdam, 20 for Amsterdam)
- Subscriber Number: 6–7 digits
Tip: When setting up International eSIM Setup or business contact numbers, always use the full international format to ensure compatibility across networks.
3. Netherlands Area Codes
The Netherlands area codes indicate the specific geographic region or city of the phone number. These are essential for both local and international communication setups.
3.1 Major Netherlands Area Codes
| City/Region | Area Code |
| Amsterdam | 20 |
| Rotterdam | 10 |
| The Hague | 70 |
| Utrecht | 30 |
| Eindhoven | 40 |
| Groningen | 50 |
3.2 Using Netherlands Area Codes
When calling within the Netherlands, you include the 0 before the area code (e.g., 020 for Amsterdam).
When calling from abroad, omit the zero and use the Netherlands country code before the area code.
Example:
- Local Call: 020 123 4567
- International Call: +31 20 123 4567
This format is especially important for International Call Forwarding and digital business setups where automated routing depends on correct number formatting.
