How to Call Norway from the US

To call Norway from the US, dial 011 + 47 + the 8-digit Norwegian number — there is no leading 0 to drop and no separate area code.

Oslo example: a landline written as 22 34 56 78 → US dial string 011 47 22 34 56 78.

Norwegian mobile example: 412 34 567 → 011 47 412 34 567.

The 011 is the US international exit code; 47 is Norway’s country code assigned by the ITU. On a smartphone, the + symbol replaces 011 — so +47 22 34 56 78 dials from any US mobile.

How to dial Norway from the US

Follow these three steps every time:

1. Dial 011 — the US exit code for all international calls. On a mobile keypad, long-press 0 to enter + as a shortcut; + works identically to 011 on smartphones.
2. Dial 47 — Norway’s ITU-assigned country code, used for every Norwegian number regardless of region or type.
3. Dial the full 8-digit number exactly as written. Unlike Germany or France, Norway uses no trunk prefix, so there is no leading 0 to remove and no area code to dial separately.

The complete pattern: 011 47 <8-digit number>.

If you see a Norwegian number already formatted with +47 (common on business cards and websites), replace the + with 011 from a US landline, or dial it as-is from a smartphone.

How Norwegian numbering works

Norway uses a closed 8-digit numbering plan administered by Nkom, the Norwegian Communications Authority. Every Norwegian number — landline or mobile — is exactly 8 digits, and you always dial all 8 from the US.

Because there is no trunk prefix and no area-code dialing, Norway has no leading-0 rule to trip over. Instead, the first digit signals the type of line:

First digit	Number type
2, 3, 5, 6, 7	Geographic landline
4, 9	Mobile
8	Toll-free / premium service

Landline numbers are conventionally written in four groups of two — AA AA AA AA — while mobile numbers are often written as AAA AA AAA. Both are 8 digits, and both are dialed identically from the US.

Norwegian landline prefixes by city

Norway has no formal area codes, but the opening digits of a landline still indicate its geographic origin. These prefixes are dialed as part of the 8-digit number — never separately.

City	Landline starts with	Example (national)	Dial from US
Oslo	2	22 34 56 78	011 47 22 34 56 78
Bergen	55	55 12 34 56	011 47 55 12 34 56
Trondheim	73	73 12 34 56	011 47 73 12 34 56
Stavanger	51	51 12 34 56	011 47 51 12 34 56

Norwegian mobile numbers do not carry a geographic prefix. A mobile beginning with 4 or 9 is reachable anywhere in the country, dialed from the US as 011 47 plus the full 8 digits.

Time zones: CET and CEST

Norway observes two time zones across the year:

• CET (Central European Time) — UTC+1, in effect from the last Sunday of October through the last Sunday of March (Norway’s “winter time”).
• CEST (Central European Summer Time) — UTC+2, in effect from the last Sunday of March through the last Sunday of October.

US time zone	Offset during CET (Oct–Mar)	Offset during CEST (Mar–Oct)
Eastern (ET)	Norway +6 h	Norway +6 h
Central (CT)	Norway +7 h	Norway +7 h
Mountain (MT)	Norway +8 h	Norway +8 h
Pacific (PT)	Norway +9 h	Norway +9 h

Important for business callers: the US and EU do not switch clocks on the same Sunday each spring. The US springs forward in early March, while Norway waits until the last Sunday of March.

For roughly three weeks in that window, Norway is temporarily only 5 hours ahead of US Eastern rather than 6. During that period a call at 8 AM ET reaches Norway at 1 PM rather than 2 PM — still fine, but worth confirming when scheduling recurring calls.

The reliable overlap window for standard business hours is 8 AM–11 AM ET, reaching Norwegian offices between 2 PM and 5 PM local time before most close.

US to Norway calling costs

Costs vary significantly by calling method:

• US carrier per-minute (no plan): AT&T and Verizon charge approximately $2–$3 per minute to Norway without an international add-on. Fine for a call or two per month.
• Carrier international add-on packages: roughly $5–$15 per month reduces rates to a few cents up to about $0.25 per minute. Worthwhile above ~30 minutes/month.
• VoIP providers (including DialPhone): flat per-minute rates to Norway that typically undercut carrier add-ons, with no monthly minimum. For US–Norway business calling at any volume, a VoIP plan on DialPhone business phone pays for itself quickly.
• Free app-to-app (WhatsApp, Signal): works if the Norwegian side also uses the app and has Wi-Fi/data. Not viable for reaching most Norwegian landlines or businesses.

See DialPhone pricing for current per-minute Norway rates included in each plan tier.

Calling Norwegian mobile vs landline from the US

From a US perspective, the dialing procedure is identical: 011 47 <8-digit number>. The difference lies in the number itself:

• Landlines start with 2, 3, 5, 6, or 7, and the opening digits hint at the city — Oslo 2, Bergen 55, Trondheim 73.
• Mobiles start with 4 or 9, carry no geographic prefix, and are reachable nationwide.

Because there is no leading 0 and no area code in either case, Norway is one of the more forgiving European countries to dial — you simply enter all 8 digits after the country code. Calling cost can still differ: Norwegian mobile destinations are sometimes priced higher per minute than landlines on US carrier plans, while VoIP providers including DialPhone typically apply a single flat rate regardless of destination type.

SMS to Norway and business use cases

US-to-Norway SMS works from most US mobile plans — the same international add-on that covers calls usually covers texts. Business-grade SMS (A2P, bulk, or CRM-triggered) requires a provider supporting international SMS routing to Norwegian networks.

US–Norway B2B context where this matters most:

• Energy and maritime: US firms working with Norway’s oil, gas, offshore wind, and shipping sectors coordinate constantly across the 6-hour gap. Reliable caller ID presentation matters when Norwegian gatekeepers screen unfamiliar US numbers.
• Seafood and exports: US importers and distributors maintaining Norwegian seafood and supplier relationships benefit from a recognizable number and predictable per-minute costs on recurring calls.
• Technology and SaaS: US software companies selling into Norwegian enterprises find that verified caller ID and timezone-aware routing meaningfully improve answer rates.

DialPhone handles the time-zone asymmetry for you: when a Norwegian contact calls your US number outside US business hours, an AI receptionist can answer, qualify the inquiry, and route or escalate based on rules you set — so a 6-hour offset never costs you the opportunity. For outbound calls, DialPhone routes with STIR/SHAKEN attestation so your caller ID passes carrier verification rather than appearing as an unverified international number.

FAQ

Calling Norway FAQ

What is the country code for Norway? +

Norway's country code is +47. From a US landline or mobile, you reach it by dialing the US international exit code 011 first, making the full prefix 011 47. From a smartphone that supports E.164 dialing you can substitute + for 011, so +47 works identically.

Do I need to drop a leading 0 when calling Norway from the US? +

No — and this is what makes Norway different from most European countries. Norway has no national trunk prefix, so Norwegian numbers are not written with a leading 0 the way German or French numbers are.

You simply dial 011 47 followed by the complete 8-digit number exactly as written. There is no 0 to add or remove, and no separate area code to dial.

How do I call a Norwegian mobile number from the US? +

Norwegian mobile numbers are 8 digits and always start with the digit 4 or 9. Dial 011 + 47 + the full 8-digit number.

Example: a mobile written as 412 34 567 is dialed from the US as 011 47 412 34 567. There is no separate area code on a Norwegian mobile — the leading digit (4 or 9) identifies it as a mobile line.

What is the best time to call Norway from the US? +

Norway is 6 hours ahead of US Eastern Time during standard time (UTC+1 vs UTC-5) and 5 hours ahead during the brief spring window when US daylight saving has started but Norway's has not. The reliable business-hours overlap is 8 AM–11 AM ET, which lands in the 2–5 PM range in Norway — still within office hours.

Note: the US and EU switch clocks on different Sundays each spring, creating a roughly three-week window where the usual offset temporarily shifts by one hour.

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

Standard US carrier rates without an international plan run roughly $2–$3 per minute to Norway. Carrier international add-on packages reduce this to a few cents to around $0.25 per minute for a monthly fee.

VoIP providers including DialPhone charge flat per-minute rates to Norwegian destinations that are typically lower than carrier add-on plans, with no monthly minimum for low-volume callers.

Can I call Norwegian toll-free (800) numbers from the US? +

Norwegian 800 freephone numbers are free only when dialed from within Norway. Calling them from the US will often fail to connect, or connect at a standard international rate rather than free.

Ask your Norwegian contact for their geographic 8-digit number (starting with 2, 3, 5, 6, or 7) as a reliable alternative you can reach from abroad.

How can I tell a Norwegian mobile from a landline? +

Read the first digit of the 8-digit number. Numbers starting with 4 or 9 are mobiles. Numbers starting with 2, 3, 5, 6, or 7 are landlines, and that opening digit also signals the geographic region — for example Oslo numbers begin with 2, Bergen with 55, and Trondheim with 73.

Numbers starting with 8 are typically toll-free or premium-rate service numbers. The dialing procedure from the US is the same in every case: 011 47 plus the full 8 digits.

How do I save a Norwegian number in my phone contacts? +

Save Norwegian numbers in full E.164 international format: +47 followed by the 8-digit number, with no leading 0 and no area code. For example, an Oslo number 22 34 56 78 should be saved as +47 22 34 56 78.

This format works from any country without modification, prevents dialing errors when roaming, and is the standard format expected by CRMs and VoIP platforms including DialPhone.
