SMS & OTP

Short answer

To send bulk SMS in Norway, use a provider with routes to Telenor, Telia and Ice, send from an alphanumeric sender ID of up to 11 characters, and send marketing to individuals only with their consent under section 15 of the Marketing Control Act and GDPR. Keep OTPs separate from promotions, give every recipient an opt-out, and write plain Norwegian: æ, ø and å fit GSM-7, so 160 characters fit one message.

Key takeaways

  • Our regulation data lists Nkom (Nasjonal kommunikasjonsmyndighet) as the telecoms regulator, with sender ID requirements set by the operators and a free-form sender ID lead time.
  • Section 15 of the Marketing Control Act (markedsføringsloven) generally bans electronic marketing to individuals who have not consented, and Forbrukertilsynet treats SMS as electronic mail for this rule.
  • Three mobile networks appear in our coverage data, all with direct routes: Telenor Norway (242-01), Telia Norway (242-02) and Ice Norway (242-14).
  • The letters æ, ø and å, in upper and lower case, are in the default GSM 7-bit alphabet, so a plain Norwegian message holds 160 characters (153 per part); emoji and curly quotation marks switch it to Unicode at 70 (67).
  • We have not found a regulator-published time-of-day window for promotional SMS in Norway; schedule promotions for local daytime and keep OTPs and alerts on a transactional route.

This guide is for marketing, e-commerce, retail and operations teams that want to send business SMS to mobile numbers in Norway: OTPs, delivery alerts, appointment reminders and promotions. It explains who regulates what, how sender IDs work, what consent you need, and how Norwegian text affects message length. It is a practical overview, not legal advice; confirm requirements with Norwegian counsel and your provider before launch.

What rules apply to bulk SMS in Norway?

Three layers apply: telecoms regulation and operator policy, the Marketing Control Act, and GDPR. None is a single "bulk SMS law", so you assemble the picture from each.

Layer What it covers Where to check
Nkom and the operators (Telenor, Telia, Ice) Telecoms regulation, routes, sender ID handling, filtering nkom.no
Marketing Control Act (markedsføringsloven), section 15 Consent for electronic marketing to individuals; supervised by Forbrukertilsynet Forbrukertilsynet guidance, Lovdata
GDPR and Datatilsynet Lawful basis, transparency and rights for personal data datatilsynet.no

Our regulation data lists Nkom as the regulator and records that sender ID requirements are set by the operators, so the rule that matters on launch day is the one your operator route enforces.

Yes, treat consent as required for marketing to individuals. Forbrukertilsynet's guidance explains that section 15 generally prohibits electronic marketing to individuals who have not consented, and that marketing by SMS and multimedia messages falls under the Act's concept of electronic mail. The Act contains an exception for existing customer relationships where the trader received the customer's electronic address in connection with a sale, but it is narrow, so ask counsel before using it.

Forbrukertilsynet cannot pre-approve marketing, and it has issued prohibition decisions with coercive fines for SMS sent without consent. Active, specific consent is the safest basis: a pre-ticked box or a general "I agree to communication" does not give you that.

Separately, GDPR applies to the phone numbers as personal data. Our regulation data records that GDPR-compliant opt-in is required, that double opt-in is the operator-preferred standard for marketing, and that a STOP keyword is honoured network-wide. A safe routine is:

  1. Record consent: the exact wording shown, date and time, channel and number.
  2. Say who is sending and why at sign-up, for example "Offers from Bergen Bakeri by SMS".
  3. Include an opt-out in every promotion and honour it at once.
  4. Keep one suppression list across SMS, WhatsApp and email.
  5. Never buy lists. Bought numbers carry no consent trail.

For wording, use our opt-in consent generator and read opt-in consent across channels for how to record it.

How do sender IDs work in Norway?

Business SMS to Norway normally uses an alphanumeric sender ID of up to 11 characters, which shows your brand instead of a number. Numeric long codes are also supported, according to our regulation data. See alphanumeric sender ID.

Our data lists the lead time as free-form. That means requirements are set by the operators and confirmed at onboarding, not that no rules exist.

Step What to do
1. Classify Decide which traffic is transactional (OTP, alerts) and which is promotional, and plan one sender ID for each
2. Choose names Use your brand name; avoid names that imitate banks, authorities or operators
3. Confirm Ask your provider for the current operator requirements for each name
4. Document Keep an authorisation letter naming the sender IDs and your provider
5. Test Send an OTP and a promotion to Telenor, Telia and Ice handsets and check how the sender displays

Our sender ID letter generator drafts the letter, the sender ID checker shows the current position, and the Norway sender ID page summarises it. If you want us to prepare and file the registration with you, see registrations; decisions stay with the operators and regulators. Background on formats is in our guide to sender ID types.

Which operators carry SMS in Norway?

Three mobile networks appear in our coverage data, each with a direct route:

Operator MCC-MNC
Telenor Norway 242-01
Telia Norway 242-02
Ice Norway 242-14

Read delivery reports per operator instead of a blended rate. Our guide to improving SMS delivery rates explains how to diagnose gaps, and an HLR lookup removes dead numbers before you send.

How should you separate OTP and promotional traffic?

Keep OTPs, order alerts and other service messages on their own sender ID and route, and put promotions on another. A promotion inside an OTP puts your login codes at risk if the sender is filtered or reported, and it can turn a service message into marketing.

Traffic Example Practice
Transactional OTP, payment confirmation, delivery alert No promotion inside; own sender ID; any hour
Promotional Sale, new product, loyalty offer Consented numbers only; opt-out in the message; daytime schedule
Mixed "Your order has shipped. Get 10% off next time" Avoid; the offer makes it promotional

For OTP content and security, read our OTP authentication messages guide.

Do æ, ø and å work in GSM-7?

Yes. The default GSM 7-bit alphabet contains æ, ø, å and their capitals, so plain Norwegian fits 160 characters per message (153 per part when split). Emoji, curly quotation marks and some symbols switch the whole message to Unicode with 70 characters (67 per part). See GSM-7 and concatenated SMS.

Encoding Single message Per part when concatenated
GSM 7-bit 160 characters 153
Unicode (UCS-2) 70 characters 67

These examples were counted against the limits:

Message Encoding Characters Parts
Din kode fra Bergen Bakeri er 482913. Ikke del den med noen. GSM-7 60 1
Bergen Bakeri: Gratis kanelbolle til kaffen i helgen! Vis denne meldingen i kassen. Avmeld: bergenbakeri.example/stopp GSM-7 118 1
Bergen Bakeri: Bestillingen din #1042 er klar til henting. Åpent til kl. 18. GSM-7 76 1
Bergen Bakeri: Gratis kanelbolle til kaffen i helgen! ☕ Vis denne meldingen i kassen. Avmeld: bergenbakeri.example/stopp Unicode 120 2

The last row shows the cost of one symbol: the same promotion jumps from one part to two. Check final copy in the SMS character counter and read SMS character limits and Unicode for other scripts.

When should you send?

We have not found a regulator-published time-of-day window for promotional SMS in Norway, and our regulation data records none. Agree sending hours with your provider, schedule promotions for local daytime (Norwegian time, CET or CEST) and avoid late evenings. OTPs and alerts can go at any hour. The send time planner helps, and SMS marketing rules by country compares hours across markets.

What is a launch checklist for Norway?

  1. Purpose split: OTP, service and promotional messages each have their own sender ID and copy.
  2. Consent store: every marketing number has wording, date, time and channel recorded.
  3. Opt-out path: a STOP keyword or link works, is tested, and feeds the suppression list the same day.
  4. Sender display: each ID is tested on Telenor, Telia and Ice handsets.
  5. Encoding check: every template is counted in the character counter and its number of parts is known.
  6. Delivery monitoring: reports are read per operator, with a named owner for failures.
  7. Fallback plan: decide what happens when an SMS fails, for example a retry or a message on a channel the customer has opted in to, such as WhatsApp.

A worked example: a Bergen bakery chain

"Bergen Bakeri" (synthetic) has nine bakeries and wants OTPs for its loyalty app, order-ready alerts and a weekly offer.

  • It uses two alphanumeric sender IDs, one for transactional and one for promotional traffic, and tests both on Telenor, Telia and Ice.
  • It collects consent in the app and at the till with an unticked box, storing wording, timestamp and number, and shows "Tilbud på SMS" with a clear opt-out.
  • OTPs and order alerts use plain Norwegian well under 160 characters.
  • The weekly offer goes only to consented numbers, is checked against the suppression list, is scheduled for local daytime and is sent without symbols so it stays at one part.
  • Opt-outs feed one suppression list that also covers email and WhatsApp.

What are the common mistakes?

  • Treating a purchase as consent. A past sale is not a general consent to promotions, and the existing-customer exception is narrow.
  • Pre-ticked boxes. Consent should be an active, specific choice.
  • No consent evidence. Without a timestamp and source you cannot answer a complaint.
  • Promotion inside a service message. It turns the message into marketing.
  • One emoji in every message. It turns a 160-character message into a 70-character one.
  • Mixing OTP and promotion on one sender ID.

Frequently asked questions

Is bulk SMS legal in Norway?

Yes. Businesses send OTPs, reminders, alerts and marketing by SMS in Norway, provided they use a legitimate route, hold a lawful basis for the numbers and, for consumer marketing, consent. No single statute is called a bulk SMS law, so the rules come from the Marketing Control Act, GDPR and the operators.

Do I need consent to send marketing SMS in Norway?

Treat consent as required. Forbrukertilsynet's guidance on section 15 of the Marketing Control Act says electronic marketing to individuals who have not consented is generally prohibited, and that SMS counts as electronic mail. The Act has a narrow existing-customer exception, so check its conditions with Norwegian counsel before relying on it.

Do I need to register a sender ID in Norway?

Our regulation data lists the sender ID position as free-form: requirements are set by the operators and BroadNet confirms the current ones during onboarding. Alphanumeric IDs of up to 11 characters are supported, as are numeric long codes. Test how your ID displays on each network before launch.

Do æ, ø and å work in GSM-7?

Yes. Æ, Ø, Å, æ, ø and å are all in the GSM 7-bit default alphabet, so Norwegian text without emoji or curly quotes fits 160 characters in one message. If a message includes an emoji or another character outside the alphabet, the whole message becomes Unicode and holds only 70.

Which operators carry SMS in Norway?

Our coverage data lists Telenor Norway, Telia Norway and Ice Norway, each with a direct route. Review delivery reports per operator, because a healthy overall rate can hide a weak network.

Can a service SMS go out without consent?

Order confirmations, OTPs and delivery alerts that serve a transaction are not marketing, so they do not need marketing consent, but they must not contain promotion. The line between service and marketing is judged by the content, so keep promotional wording out of transactional messages and ask counsel about edge cases.
