Netherlands numbering plan & how to dial
Dialing into Netherlands means working with an open numbering plan under country code +31: a 2-digit prefix plus a 8-digit subscriber number, 10 digits total. Locally, numbers usually carry a leading "0" that gets dropped when calling Netherlands from outside the country.
Mobile coverage in Netherlands comes from 3 major networks — KPN, Vodafone Netherlands, T-Mobile Netherlands — with internet penetration at 96%. VoIP is permitted and regulated by ACM (Authority for Consumers and Markets). Language (Dutch) and currency (EUR) both matter here for IVR, SMS, and scheduling support around local business hours.
Most European numbering plans follow ITU-T E.164 with a national trunk prefix that is dropped for international dialing, and cross-border VoIP is widely supported across the region.
Skipping the exit code
From the US you must dial 011 before the +31 country code to reach Netherlands.
Keeping the national trunk "0"
Netherlands numbers often show a domestic leading 0 — drop it once you've dialed the +31 country code from outside the country.
Ignoring the time difference
UTC+1 governs local business hours in Netherlands; confirm the time there before placing the call.
Permitted — ACM regulated
Regulated by ACM (Authority for Consumers and Markets)

- Emergency service access (112) is mandatory for all VoIP operators serving Dutch subscribers.
- The Netherlands has one of Europe's strongest GDPR enforcement regimes via the Dutch DPA (Autoriteit Persoonsgegevens).

FAQ
Calling Netherlands — frequently asked questions
No license restriction beyond standard regulation — ACM (Authority for Consumers and Markets) permits VoIP in Netherlands for compliant operators. That keeps setup straightforward for a Twiching customer looking to call or text into the country.
Amsterdam is the capital of Netherlands. A local +31 number is recognisable to callers there and nationwide, which is part of why presenting local caller ID tends to improve answer rates across the whole country, not just the capital.
Yes, where locally supported — a single Twiching Netherlands number can handle both voice calls and SMS. That avoids the overhead of provisioning and managing two separate numbers for one customer-facing line.
Calls from Netherlands to the US start at $0.007/min on Twiching, billed per second rather than rounded up to the minute. That rate applies regardless of which of the major local carriers the call originates on.
ACM (Authority for Consumers and Markets) is the regulator for Netherlands. Twiching routes calls in line with its rules for compliant, licensed termination, rather than relying on unlicensed grey routes that can be blocked or degraded.
Twiching rates to Netherlands start at $0.008/min, and calls back from Netherlands to the US start at $0.007/min. Both directions are billed per second rather than rounded up to the nearest minute, on Tier-1 routes throughout.
