In this article, we will tell you how to collect client phone numbers for text marketing in a legal way and what GDPR says about it.

Why buying mobile numbers for marketing is not an option?

It may seem an easy and fast way to get new contacts. But purchasing a third-party database is illegal because people haven’t given their consent to the use of their personal data.

It is absolutely possible, that the receivers of your mass SMS texts sue you. If they win a judicial proceeding, you will have to pay from $500 to $1000 for each undesired SMS.

But don’t worry. We’ll tell you how to get new clients and increase conversion instead of receiving spam complaints.

7 GDPR principles of personal data processing in work with a list of phone numbers

1. Legitimacy, fairness, and transparency. Users should know the aim of collecting their data. Add a line with the aim of cell phone collecting to your subscription form.
2. Limited purposes. The data should be used only in those purposes that have been claimed. In addition, you need to distinguish between transactional messages that provide basic information and marketing messages that promote something or offer the customer something for participating. Customers must opt-in to receive either or both. If you send a marketing message to customers who have specified they only want transactional messages, you could be legally liable. Jiffy Lube, for example, was fined $47 million for sending text messages offering a 45% discount on oil changes to customers who did not opt-in to receive them.
3. Minimization of data. You shouldn’t collect extra data. For example, for bulk text messaging list the name and mobile number will be enough. In some cases, to personalize texts, marital status, age, and interests can be required.
4. Accuracy. All the information should be proper and up-to-date. All the incorrect or obsolete phone numbers should be deleted.
5. Restriction of storage. The term of storage mobile numbers list shouldn’t exceed the duration of mass SMS campaign.
6. Integrity, security, and confidentiality. You have to take care of the security of personal data of users. You shouldn’t transfer the phone number lists to anyone by yourself and prevent cybercriminals to steal them.
7. Double opt-in. All the receivers should permit you to send the messages. The first step is putting a check on the “I agree to process my personal data” line. The second step is replying “Yes” or “No” on the question about further texting after the first message.

Other legislative requirements for collecting phone numbers list

The users should necessarily give their approval for the processing of personal data. It has to be expressed in a certain action.
For example, if you have put on your website’s sign-up form, add the “I agree to have my personal data processed” checkbox. Visitors should check it by themselves.

It is wrong to use a square with a check by default. In this case, the user doesn’t commit any actions to give consent.
