How to Call Netherlands from the US

To call the Netherlands from the US, dial 011 + 31 + area code (drop leading 0) + local number.

Amsterdam example: 011-31-20-XXXX-XXXX. Mobile example: 011-31-6-XXXX-XXXX. From a US mobile, replace 011 with + for the same result.

The 011 is the US international exit code. The 31 is the Netherlands country code, assigned by the ITU. The leading 0 in every Dutch area code is a domestic trunk prefix — drop it when dialing from abroad.

Step-by-step: how to dial the Netherlands from the US

1. Dial 011 — the US international exit code. Every international call from a US landline starts here. On a US mobile, long-press 0 to enter + as a shortcut that resolves to the local exit code automatically.
2. Dial 31 — the Netherlands country code.
3. Dial the Dutch area code without its leading 0. Amsterdam’s domestic code is 020; from the US you dial 20. Rotterdam’s domestic code is 010; from the US you dial 10.
4. Dial the local subscriber number exactly as listed, no spaces required.
5. Press call.

Full pattern: 011-31-<area code minus 0>-<local number>.

If you have a Dutch number already in E.164 format (for example +31 20 XXXX XXXX), replace the + with 011 from a US landline, or dial it as-is with the + from a US mobile.

Dutch area codes: major cities

Dutch landlines use geographic area codes. All are written with a leading 0 domestically; drop that 0 when dialing from the US.

City	Domestic code	Dial from US (after 011-31)
Amsterdam	020	20
Rotterdam	010	10
The Hague (Den Haag)	070	70
Utrecht	030	30
Eindhoven	040	40
Groningen	050	50
Tilburg	013	13
Breda	076	76
Nijmegen	024	24
Mobile (all carriers)	06	6

Dutch area codes can be two or three digits in their domestic form (always including the leading 0). Amsterdam and Rotterdam use two-digit codes; most other cities use three digits.

How to call a Dutch mobile from the US

All Dutch mobile numbers begin with 06 in national format, followed by 8 digits.

National format: 06-1234-5678 From the US: 011-31-6-1234-5678

Drop the leading 0, dial 6, then the 8 remaining digits. Every Dutch mobile — regardless of carrier (KPN, T-Mobile NL, Vodafone NL) — follows this pattern. You cannot distinguish carrier from the number format, but you can always tell mobile from landline: anything starting 06 is a mobile.

Dutch mobile calls cost slightly more per minute than landline calls on most US carrier per-minute plans. VoIP providers typically offer a single flat rate for all Dutch destinations.

Netherlands telecom regulator: ACM

Dutch telecommunications are overseen by the ACM (Autoriteit Consument & Markt — Authority for Consumers and Markets), the independent regulator that also handles competition and consumer protection.

ACM governs Dutch numbering plans, number portability rules, and interconnection. From a US caller’s perspective this is relevant when porting a Dutch number or when a Dutch business tells you their number is “ACM-regulated” — it confirms the number is a legitimate Dutch allocation.

For number portability context in your own telecom stack, see the number porting guide.

Time zone: when to call the Netherlands from the US

The Netherlands observes Central European Time (CET), UTC+1 in winter, and shifts to Central European Summer Time (CEST), UTC+2, during summer.

US time zone	Offset to Netherlands (standard)	Offset (summer/CEST)
Eastern (ET)	+6 hours	+6 hours*
Central (CT)	+7 hours	+7 hours*
Mountain (MT)	+8 hours	+8 hours*
Pacific (PT)	+9 hours	+9 hours*

*The US and Europe switch DST on different dates in spring (Europe switches about a week earlier). For roughly one week each March and autumn the offset shifts by one hour.

Practical window for business calls: Dutch business hours run approximately 08:30–17:30 CET. That maps to 02:30–11:30 ET / 23:30–08:30 PT. For West Coast callers this means morning calls are the only viable window — a 9 AM Pacific call reaches the Netherlands at 18:00 local, just at the end of the Dutch business day.

Cost: what you pay to call the Netherlands from the US

Dutch calling costs from US lines fall into three buckets:

• Per-minute without an international plan: roughly $0.05–$0.25 per minute to Dutch landlines; mobile can be slightly higher. T-Mobile, AT&T, and Verizon publish current rates in their international dialing pages.
• Carrier international add-on packages: $5–$15 per month reduces per-minute rates, typically to $0.10–$0.20 for Dutch destinations regardless of landline vs mobile.
• VoIP (including DialPhone): generally the lowest-cost path. DialPhone’s business phone charges a flat per-minute rate to Dutch destinations under each plan — no monthly minimums, and for teams calling the Netherlands regularly, total costs run 70–85% below major carrier add-on rates. See DialPhone pricing for current Dutch calling rates per plan tier.

For occasional callers — fewer than 30 minutes per month — a per-minute carrier rate is fine. For sales teams, logistics coordinators, or finance teams calling Amsterdam or Rotterdam weekly, a VoIP plan pays for itself within the first billing cycle.

Mobile vs. landline, and WhatsApp’s role in the Netherlands

The Netherlands has unusually high smartphone penetration and one of the highest WhatsApp adoption rates in Europe. A large share of Dutch consumers — and many SMEs — use WhatsApp as their primary messaging and casual voice channel. If you are reaching a Dutch individual informally, a WhatsApp call over Wi-Fi is free and widely expected.

For business-to-business calling — particularly in logistics (Port of Rotterdam), finance (ING, ABN AMRO, Rabobank), or technology (ASML, Philips, NXP) — standard voice calls remain the norm for formal engagement.

The practical approach: use WhatsApp for informal follow-ups and SMS for transactional notifications; use a VoIP system for outbound prospecting and inbound support where call recording, STIR/SHAKEN caller-ID verification, and CRM integration matter.

SMS and business calling: US–Netherlands trade context

The US and Netherlands have substantial bilateral trade ties. The Port of Rotterdam is Europe’s largest port and a critical transshipment hub for US exports to Europe. ASML, headquartered in Eindhoven, is the world’s sole manufacturer of extreme ultraviolet (EUV) lithography machines — essential to the global semiconductor supply chain. Philips (Amsterdam) maintains significant US operations in health technology.

For US logistics, semiconductor, and finance teams that communicate regularly with Dutch counterparts:

• Outbound calls from a DialPhone business phone number using STIR/SHAKEN attestation present as verified US numbers to Dutch carrier networks, which have adopted the CNAM and caller-verification frameworks compatible with US attestation standards. This improves answer rates on cold outreach compared to unverified or spoofed-looking numbers. See STIR/SHAKEN explained.
• For high-frequency US-to-NL call flows, a free trial lets you benchmark VoIP per-minute rates against your current carrier bill before committing.
• If you need to receive Dutch inbound calls without a Dutch SIM, a Dutch DID (Direct Inward Dialing number) on a Dutch geographic code presents locally to Dutch callers — the same principle as the UK calling guide.

FAQ

Frequently asked questions

What is the country code for the Netherlands? +

The Netherlands country code is +31, assigned by the International Telecommunication Union (ITU). From a US landline you reach it by dialing the US exit code 011 first, making the full prefix 011-31.

From a US mobile you can substitute + for 011 and dial +31 directly followed by the Dutch number with its leading 0 removed.

How do I call Amsterdam from the US? +

Amsterdam's area code is 020 in domestic format. When calling from the US, drop the leading 0 so the area code becomes 20.

The full dial string is: 011-31-20-XXXX-XXXX. On a US mobile: +31-20-XXXX-XXXX. An 8-digit Amsterdam local number plus 011-31-20 gives you a 14-digit total dial string.

How do I call a Dutch mobile from the US? +

All Dutch mobile numbers start with 06 in national format and carry 8 digits after the prefix. When calling from the US, drop the leading 0 so 06-1234-5678 becomes 011-31-6-1234-5678.

Mobile calls to the Netherlands typically cost slightly more per minute than landlines on US carrier plans. VoIP rates do not usually differentiate between landline and mobile for Dutch destinations.

What time zone is the Netherlands in? +

The Netherlands observes Central European Time (CET), which is UTC+1 in winter. During daylight saving time (late March to late October) it shifts to Central European Summer Time (CEST), which is UTC+2.

Relative to the US: the Netherlands is 6 hours ahead of Eastern Time, 7 hours ahead of Central, 8 hours ahead of Mountain, and 9 hours ahead of Pacific during standard time. DST transitions differ by roughly a week between the US and Europe, so the offset can shift by an hour for a short window each spring and autumn.

How much does it cost to call Netherlands from the US? +

Traditional US carrier per-minute rates to Dutch landlines run roughly $0.05–$0.25 per minute without an international plan. Mobile destinations can be higher. Carrier international add-on packages typically reduce this to $0.10–$0.20 per minute for a monthly fee.

VoIP providers generally offer the lowest path — DialPhone charges a flat per-minute rate to Dutch destinations with no monthly minimum, typically well below major carrier add-on rates. For teams with regular US-to-Netherlands call volume, VoIP reduces costs by 70–85% compared to traditional carrier pricing.

Do US toll-free numbers work in the Netherlands? +

No. US toll-free numbers (800, 888, 877, 866, 855, 844, 833) are toll-free only within the North American Numbering Plan (NANP), which covers the US, Canada, and certain Caribbean territories.

A caller in the Netherlands attempting to dial a US 800 number will either receive an intercept message or pay international rates if the call connects at all. For Dutch callers, provide your direct inward dialing (DID) number in E.164 format (+1 area-code local) rather than a US toll-free number.

Can I use WhatsApp to call the Netherlands instead? +

Yes, and this is very common. The Netherlands has one of the highest WhatsApp adoption rates in Europe — a significant share of Dutch consumers and many SMEs use WhatsApp as their primary messaging channel.

WhatsApp calls use your internet connection and are effectively free over Wi-Fi. For informal or consumer-facing contact, WhatsApp is an acceptable alternative. For authenticated business calls — where caller ID verification (STIR/SHAKEN) and call recording matter — a VoIP phone system is the more appropriate tool.

Why does my call to a Dutch number fail to connect? +

The most common reasons: leaving the leading 0 in the Dutch area code after dialing 011-31 (for example, dialing 011-31-020 instead of 011-31-20); omitting the 011 exit code entirely; international calling being disabled on your US line by default; or low balance on a prepaid plan.

Fix: confirm international calling is enabled in your carrier account, then redial in strict 011-31-- format.
