Similarities and differences in international SMS

It’s important to understand how SMS differs among the countries you send to. In the following sections, we provide a brief overview of important distinctions to keep in mind. This is not a comprehensive list, so make sure you review and abide by all laws, regulations, and industry guidelines for each country you send to. Find more information about localized messaging compliance laws.

Two-way messaging (which is required for two-way SMS, all keywords, etc.) is not available for branded sender IDs.

More info on two-way messaging 

Two-way messaging for SMS simply means that the recipient can text you back. This functionality is required for: 

  • SMS conversations
  • Opt-in keywords
  • Opt-out keywords
  • Conversational flows 

However, branded sender IDs cannot receive text messages. Thus, if you're using a branded sender ID in a certain country, you cannot use these features. 

North America

The United States and Canada share a country code (+1) and some area codes. However, their regulations are not exactly the same. If you aren’t sure which country a message will go to, follow the applicable SMS marketing regulations for both countries.

United States

In the United States, the rules and regulations of the Telephone Consumer Protection Act (TCPA) and the guidelines of the Cellular Telecommunications Industry Association (CTIA) are the two primary frameworks that apply to SMS marketing. When sending to a US phone number, you must follow the rules and guidelines set out by the TCPA and CTIA and all other applicable laws and regulations. Check out this article to learn about US SMS compliance laws. 

You must get express consent to send an SMS or MMS message to any US phone number. 

In your messages, it is highly recommended that you include:

  • Your organization’s name or a way for recipients to easily identify your brand
  • Instructions on how to opt out from receiving future messages

You should not include any prohibited SMS and MMS content in your messages. If you do, carriers will likely filter your message, and it will never land in your intended recipients’ messaging app(s). 

US short codes can only send to US phone numbers. If you want to send to other countries, such as Canada, either use a toll-free number or request a separate short code.

Canada

SMS marketing in Canada is regulated under the Canadian Anti-Spam Legislation (CASL). CASL applies to the sending of many different types of commercial electronic messages (CEMs), including commercial emails, SMS/MMS messages, and social media communications. For more information on CASL, read about Canada's Anti-Spam Legislation. 

You must get express consent to send an SMS or MMS message to any Canadian phone number using Klaviyo. 

CEMs sent to Canadian recipients must include: 

  • Information that identifies the sender of the message and, if applicable, the person on whose behalf the message is sent
  • Contact information for the sender, including:
    • Business name
    • A valid mailing address
    • Either an email address, phone number, or web address for contacting your organization; your mailing address must be valid for at least 60 days after your message is sent
  • Instructions on how to opt-out from receiving future messages

Do not include prohibited SMS and MMS content in your messages. If you do, carriers will likely filter your message, and it will never land in your intended recipients’ messaging app(s). 

MMS is only available for toll-free numbers in Canada and for long codes in Australia. It is not available for short codes or branded sender IDs in these countries. 

United Kingdom

In the UK, SMS messaging falls under the UK General Data Protection Regulation (GDPR). This regulation covers most aspects of storing, collecting, and using someone’s personal data. Check out this article to see how UK GDPR affects SMS.

In messages to UK recipients, you must include:

  • Organization name or identifier (e.g., a branded sender ID)
  • Unsubscribe link or opt-out keywords

In the UK, SMS marketing messages can be sent from:

Australia

In Australia, the Spam Act 2003 and the Spam Regulations 2021 regulate the sending of SMS marketing messages, along with other commercial electronic messages (e.g., email and instant messages). For more information, read about Australia’s Anti-Spam legislation.

Messages to Australian recipients must include:

  • Legal business name or company name and Australian business number
  • Contact details or a link to business contact details
  • Option to unsubscribe (e.g., opt-out link or keyword) 

There are 2 sending numbers for Australia. Both must undergo a type of registration or verification process before you can use them to send SMS messages in Australia:

New Zealand

In New Zealand, SMS messages are regulated by the Unsolicited Electronic Messages Act 2007 and the Privacy Act 2020, which also oversee other commercial electronic messages (e.g., email and instant messages). 

Messages to New Zealand recipients must include:

  • Contact details or a link to business contact details
  • Opt-out keyword 

Short codes are the only sending number available in New Zealand. 

Here, one SMS equals 10 credits. MMS is not available. 

European Union

In any country in the EU, SMS is regulated by GDPR and the EU ePrivacy Regulations. These regulations detail many aspects of how you can store, collect, and use someone's personal data. Learn about SMS compliance in the European Union. 

In messages to EU recipients, you must include:

  • Organization name or identifier (e.g., a branded sender ID)
  • Unsubscribe link or opt-out keywords

Double opt-in, where available, is always recommended as a best practice. This is particularly the case in Germany and some other E.U. countries, such as Austria and Switzerland, where double opt-in is the preferred way of demonstrating that consent has been properly and lawfully obtained.

Note that Irish long codes require verification. 

MMS is not available at this time for any country in Europe.
