Opt-In and Opt-Out Requirements

There is no specific regulation on opt-in process, but carriers can request evidence of opt-in at any time, so following these best practices is recommended:

  • Prior consent or right to opposition will be collected by means of a checkbox, either online or offline. Pre-checking the box as default is to be avoided at all times.
  • Advertising by SMS is possible provided that people have explicitly agreed to be approached, at the time of collection of their mobile phone number.

Two exceptions to this principle:

  • if the person being prospected is already a client of the company and the prospecting concerns products or services similar to those already provided by the company.
  • if the prospect is not of a commercial nature (charitable for example).

In both cases, the person must, at the time of collecting his telephone number:

  • be informed that their mobile phone number will be used for prospecting purposes.
  • to be able to oppose this use in a simple and costless way.

Each message should:

  • specify the identity of the advertiser.
  • propose a simple way to oppose receiving new messages (for example, a non-premium phone number where it is possible to unsubscribe at the end of the message). 
  • have various possibilities (mobile, desktop, website etc) for the subscriber to opt-in and especially to opt-out.
  • In case of marketing purposes the opt-out must be well documented - users can opt-out by sms, via email or website, sending a form, contacting the brand etc. There must always be a way out and it must be well documented.

Opt-in must meet Valid Consent GDPR Requirements. 

Opt-in and Opt-out processes must be very well documented on the customer side in the Terms and Conditions.
