Businesses send OTPs, booking reminders, alerts and marketing by SMS in Sweden, provided they use a legitimate route, have a lawful basis for the numbers and, for consumer marketing, prior consent. There is no single bulk SMS statute, so the rules come from the Marketing Act, GDPR and the operators." - q: "Do I need consent to send marketing SMS in Sweden?" a: "Treat consent as required. The Marketing Act requires prior consent for marketing to individuals through electronic mail, which the EU framework defines to include SMS, and Konsumentverket supervises it. Our regulation data also calls for GDPR-compliant opt-in. Keep a record of when and how each number agreed, and ask Swedish counsel about exceptions." - q: "Do I need to register a sender ID in Sweden?" a: "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, and numeric long codes too. Test how your ID displays on each network before a launch." - q: "Do å, ä and ö work in GSM-7?" a: "Yes. Å, Ä, Ö, å, ä and ö are all in the GSM 7-bit default alphabet, so Swedish 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." - q: "Which operators carry SMS in Sweden?" a: "Our coverage data lists Telia Sweden, Tele2, Telenor Sweden and Tre Sweden, each with a direct route. Review delivery reports per operator, because a healthy overall rate can hide a weak network." - q: "Can I send SMS in other languages in Sweden?" a: "Yes. Finnish, Arabic, Somali and other languages are common among Swedish audiences. Latin-script languages that need characters outside GSM-7 are sent as Unicode with a 70-character limit, and Arabic is always Unicode. Plan message length per language and test copy in a character counter." sources: - title: "Post- och telestyrelsen (PTS)" url: "https://www.pts.se/" - title: "Konsumentverket: Swedish Consumer Agency" url: "https://www.konsumentverket.se/" - title: "Marknadsföringslag (2008:486)" url: "https://lagen.nu/2008:486" - title: "Integritetsskyddsmyndigheten (IMY): Swedish Authority for Privacy Protection" url: "https://www.imy.se/" - title: "3GPP TS 23.038: Alphabets and language-specific information" url: "https://www.3gpp.org/dynareport/23038.htm" --- # Bulk SMS in Sweden: PTS, Consent and Swedish Text (å ä ö) Canonical: https://omnichannels.ai/blog/bulk-sms-sweden-guide/ Language: en Publisher: OmniChannels.ai by BroadNet Technologies This guide is for marketing, e-commerce, retail and operations teams that want to send business SMS to mobile numbers in Sweden: OTPs, delivery alerts, booking reminders and promotions. It explains who regulates what, how sender IDs work, what consent you need, and how Swedish text affects message length. It is a practical overview, not legal advice; confirm requirements with Swedish counsel and your provider before launch. ## What rules apply to bulk SMS in Sweden? Three layers apply: telecoms regulation and operator policy, the Marketing Act, and GDPR. None is a single "bulk SMS law", so you assemble the picture from each. | Layer | What it covers | Where to check | |---|---|---| | PTS and the operators (Telia, Tele2, Telenor, Tre) | Telecoms regulation, routes, sender ID handling, filtering | [pts.se](https://www.pts.se/) | | Marketing Act (marknadsföringslagen, 2008:486) | Marketing to individuals, including prior consent for electronic marketing; supervised by Konsumentverket | [Konsumentverket](https://www.konsumentverket.se/), [law text](https://lagen.nu/2008:486) | | GDPR and IMY | Lawful basis, transparency and rights for personal data | [imy.se](https://www.imy.se/) | Our regulation data lists PTS (Post- och telestyrelsen) 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. ## Do you need consent to send marketing SMS in Sweden? Yes, treat prior consent as required for marketing to individuals. The Marketing Act requires prior consent for marketing to natural persons through electronic mail and similar means; the EU framework behind it counts SMS as electronic mail, and Swedish preparatory works for the rule say so. Konsumentverket supervises compliance. B2B messages and customer-service messages are treated differently, so ask Swedish counsel before relying on an exception. 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 clearly that the message is marketing** and who is sending it. Swedish case law on SMS marketing has stressed that the commercial nature of a message must be clear to the recipient. 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](/tools/opt-in-consent-generator/) and read [opt-in consent across channels](/blog/opt-in-consent-multichannel-campaigns/) for how to record it. ## How do sender IDs work in Sweden? Business SMS to Sweden 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](/glossary/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. Practical steps: | 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 Telia, Tele2, Telenor and Tre handsets and check how the sender displays | Our [sender ID letter generator](/tools/sender-id-letter-generator/) drafts the letter, the [sender ID checker](/tools/sender-id-checker/) shows the current position, and the [Sweden sender ID page](/sender-id/sweden/) summarises it. If you want us to prepare and file the registration with you, see [registrations](/services/registrations/); decisions stay with the operators and regulators. Background on formats is in our guide to [sender ID types](/blog/sms-sender-id-types-explained/). ## Which operators carry SMS in Sweden? Four mobile networks appear in our coverage data, each with a direct route: | Operator | MCC-MNC | |---|---| | Telia Sweden | 240-01 | | Tele2 | 240-07 | | Telenor Sweden | 240-08 | | Tre Sweden | 240-02 | Read delivery reports per operator instead of a blended rate. Our guide to [improving SMS delivery rates](/blog/sms-not-delivered-improve-delivery-rate/) explains how to diagnose gaps, and an [HLR lookup](/glossary/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. | 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; marketing clearly identified; opt-out in the message; daytime schedule | | Mixed | "Your parcel has shipped. Get 10% off next time" | Avoid; the offer makes it promotional | For OTP content and security, read our [OTP authentication messages guide](/blog/otp-authentication-messages-guide/). ## Do å, ä and ö work in GSM-7? Yes. The default GSM 7-bit alphabet contains å, ä, ö and their capitals, so plain Swedish 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](/glossary/gsm-7/) and [concatenated SMS](/glossary/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 kod från Fika Göteborg är 482913. Dela den inte med någon.` | GSM-7 | 62 | 1 | | `Fika Göteborg: Gratis kanelbulle till kaffet i helgen! Visa detta sms i kassan. Avregistrera: fikagbg.example/stopp` | GSM-7 | 115 | 1 | | `Fika Göteborg: Din beställning #1042 är klar att hämta. Öppet till 18.00.` | GSM-7 | 73 | 1 | | `Fika Göteborg: Gratis kanelbulle till kaffet i helgen! ☕ Visa detta sms i kassan. Avregistrera: fikagbg.example/stopp` | Unicode | 117 | 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](/tools/sms-character-counter/) and read [SMS character limits and Unicode](/blog/sms-character-limits-unicode-arabic/) for other scripts. ## When should you send? We have not found a regulator-published time-of-day window for promotional SMS in Sweden, and our regulation data records none. Agree sending hours with your provider, schedule promotions for local daytime (Swedish time, CET or CEST) and avoid late evenings. OTPs and alerts can go at any hour. The [send time planner](/tools/send-time-planner/) helps, and [SMS marketing rules by country](/blog/sms-marketing-rules-by-country/) compares hours across markets. ## A worked example: a Gothenburg café chain "Fika Göteborg" (synthetic) has twelve cafés and wants OTPs for its 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 Telia, Tele2, Telenor and Tre. - It collects consent in the app and at the till, storing wording, timestamp and number, and shows "Erbjudanden via sms" with a clear opt-out. - OTPs and order alerts use plain Swedish at 160 characters or fewer. - The weekly offer says clearly that it is marketing, 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 is a launch checklist for Sweden? Work through this list before the first live send, and keep the answers in one place for audits. 1. **Purpose split:** OTP, service and promotional messages each have their own sender ID and message 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 within the same day. 4. **Sender display:** each sender ID is tested on Telia, Tele2, Telenor and Tre handsets, and the brand name reads correctly. 5. **Encoding check:** every template is counted in the character counter, and the 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 another channel such as WhatsApp. 8. **Documentation:** the authorisation letter, privacy notice and records of processing are filed. WhatsApp is a useful complement for customers who have opted in to it, but SMS reaches every handset without an app, which is why it stays the baseline for OTPs and urgent alerts. Our [channel fallback](/glossary/channel-fallback/) page explains how the two are combined. ## What are the common mistakes? - **Marketing without prior consent.** A past purchase is not a general consent to promotions. - **No consent evidence.** Without a timestamp and source you cannot answer a complaint. - **Messages that hide that they are advertising.** Make the commercial nature clear. - **Look-alike sender names.** Names imitating banks or authorities risk blocking. - **One emoji in every message.** It turns a 160-character message into a 70-character one. - **Mixing OTP and promotion on one sender ID.** ## How OmniChannels.ai helps OmniChannels.ai is powered by BroadNet, which has direct routes to Telia, Tele2, Telenor and Tre in our coverage data.
