What is the Netherland COuntry Code

What Is the Netherlands Country Code?

01 Sep 2025

Calling your parents in Amsterdam or checking on a friend in Rotterdam? The fix is simple: dial +31 before the Dutch number and drop the leading 0 you see in local formats. That's how you reach any Dutch mobile or landline from abroad. In short: the Netherlands uses +31, a trunk prefix 0 for domestic calls, and numbers that become international when you save them as +31... The International Telecommunication Union lists +31 for the Netherlands.

Netherlands Number Code: How Do I Dial the Netherlands from Any Country?

Five quick steps (works from any network): This simple guide shows how to call a Netherlands phone number from abroad—let's break it down:

  • Dial your country's international access (exit code) or just use + on mobile.
  • Enter 31.
  • Remove the leading 0 from the Dutch number.
  • Add the area code (for landlines) or 6 (for mobiles).
  • Dial the remaining digits.

Examples

  • Amsterdam landline: +31 20 123 4567 (local 020 ? international 20)
  • Dutch mobile: +31 6 12 34 56 78 (local 06 ? international 6)

If you forget the country code for the Netherlands, remember this shortcut: +31, then the number without its first 0. +31 is the Netherlands country code used for international calls.

Which prefixes map to cities—and why does this matter?

Dutch geographic numbers are tied to places. Knowing the city code prevents failed calls and helps you spot local vs. non-geographic lines (like 0800). (Research note: the government explains that fixed numbers are location-bound; 06 is always mobile; 0800 is toll-free and 090x carry charges.)

What about mobiles, 0800, and service numbers?

  • Mobiles: Dutch mobile numbers start with 06 domestically ? save as +31 6**...** abroad; after +31 6, the remaining digits are the subscriber number.
  • Toll-free: 0800 numbers are free for callers inside the Netherlands.
  • Service/Premium: 0900/0906/0909 may charge per minute or per call and are often not reachable from abroad.
  • Corporate/non-geo: 088 (company blocks), 085 (VoIP/non-geo) are often used for business lines or a cloud phone system.
  • Municipal short code: 14xxx connects to local councils.

How should I format Dutch numbers for apps and verifications?

Use the international format everywhere you store phone contacts—banking apps, messaging, and verification details:

  • Landline: +31 20 123 4567 (no parentheses or leading 0 in data fields)
  • Mobile: +31 6 12 34 56 78
  • Keep spaces for readability; avoid hyphens in form fields that require digits only.

This also reduces friction when confirming transfers with ACE Money Transfer. This format helps when making international calls or receiving callbacks internationally, with fewer "number not recognized" issues during two-factor checks or callback verifications.

How do I place calls from inside the Netherlands to other countries?

From within the Netherlands, follow international dialing rules by entering the international prefix 00 + country code + number. Example: calling the UK ? 00 44 ..., with the exact rates depending on your provider. (Remember: 44 is the country code for the UK, not the Netherlands.)

Which emergency number works nationwide (and in the EU)?

Dial 112 for emergencies—police, fire, or ambulance. Its free of charge across the EU, including the Netherlands. The Dutch government's portal confirms 112 as the national emergency line, available for life-threatening situations.

Can I trust the rules above—are they official?

Yes. Two authoritative signposts:

  • +31 is the official international code assigned by the United Nations' ITU.
  • Number categories (06, 0800, 090x, etc.) and examples are explained by the Dutch government's consumer site.

Why does this matter for remittances?

Most senders call or message loved ones, clients, or partners to confirm details and reach them for personal or work-related needs. IBAN, pickup location, or delivery time, and the right format matters in every case. Saving contacts in +31 format prevents failed calls, missed SMS codes, and delays. It's a small habit that makes sending money online with ACE smooth and stress-free.

FAQs

Do I always dial +31, even for mobiles?

Yes, for international calls to any number in the Netherlands, including mobile phones, you should dial the plus sign (+) followed by the country code for the Netherlands (31), and then the national number, dropping the leading zero if present; this rule applies when calling from anywhere in the world.

Are 0800 numbers free, and can I dial them from abroad?

0800 is toll-free inside the Netherlands; from abroad these may not connect, or the foreign operator may charge/deny routing.

What do 0900/0906/0909 numbers mean?

They are service/premium numbers with per-call or per-minute fees; many overseas carriers block them. Check the rate notice before calling.

What should I dial in an emergency?

Dial 112. It works across the EU and is free from fixed and mobile phones.

Which common city codes should I memorize?

Amsterdam 020, Rotterdam 010, The Hague 070, Utrecht 030, Eindhoven 040. Convert to +31 20 / 10 / 70 / 30 / 40 from abroad.

Stay connected

Now you can dial the Netherlands without guesswork with a simple format: save contacts as +31, drop the 0, use city codes like 20/10/70/30/40, and 06 for mobiles. Keep this format for calls, SMS codes, and account verifications, and when you're ready to help back home, your transfers with ACE will be fast and hassle-free. Put simply: the country code of the Netherlands is +31, and every number is easiest to use when saved in that format, since using the wrong format can lead to high costs with some services or failed connections.
