afaik no businesses are required by the gdpr to collect phone numbers, and would like to see evidence otherwise

There are no occurrences of "cell" or "phone" in GDPR, and the only relevant occurrences of "number" are about "national identification numbers", which phone numbers are not.

Sorry, I should have been more specific. In Europe (or Germany at least) it’s required by law that you provide an imprint with contact information for every site you host, as well as a privacy policy that includes contact information of your GDPR officer if you collect any kind of personalized data. Since I’m a one-person company, that includes my personal phone number since I don’t have a business phone. Also chrome webstore for example requires a phone number if you host an extension on there.

Edit: Also this wasn’t about collecting phone numbers, but about providing one for your business if you host a publically accessible site

... always wondered if the cell phone requirements are not (also) tied to then wanting an actual, physical, person behind each account - as in most EU jurisdictions each SIM card is tied to an actual ID.-

In many EU countries, you can buy sim cards from some vending machine, in a grocery store or places where you can buy international telephone cards. No ID required. But phone plans are often tied to your home internet.

are you sure no ID is required to activate the cards? at least in austria and i believe in germany you can't get a sim card without an ID.

If you get a lyca sim card, even there you don't need ID to use it. There might be some restrictions after a month though.

Ah, the EU — land of fine cheeses, indecipherable GDPR popups, and, of course, the iron-fisted grip on your humble little SIM card. In the EU, you can’t even sneeze near a prepaid phone number without showing at least three forms of government-issued ID, a notarized statement of purpose, and possibly a blood sample. Why? Because buying a SIM card anonymously here is about as legal as fencing stolen paintings in the town square.-

You see, most EU countries decided some time ago that allowing people to own mobile numbers without a background check was simply too dangerous. What if someone used a burner phone to commit fraud, or worse — say something mildly controversial on the internet? To prevent such dystopian chaos, SIM registration laws were born. Now, whenever you purchase a SIM card in France, Germany, Spain, or pretty much anywhere with croissants, you have to offer your passport, soul, and, ideally, a letter of recommendation from your local constable.-

The result? Your phone number in the EU is no longer just a string of digits—it’s basically your name, address, and social security number all rolled into one. It’s like a little snitch in your pocket, ready to identify you at the first sign of online mischief. Online platforms know this. That’s why so many of them, from social networks to AI models, insist on a phone number. They’re not just trying to text you cute security codes — oh no, they’re trying to make sure there’s a warm, squishy, legally-recognizable human on the other end. Preferably one without too many fake Twitter accounts.-

Technically, GDPR is supposed to protect your data. That includes your phone number. But there’s a loophole the size of Luxembourg: if the phone number is used to stop terrorism, fraud, bots, or people being mean in the comments, then suddenly it’s all hands on deck. Platforms benefit from the comforting knowledge that EU phone numbers are like digital dog tags: traceable, trackable, and just annoying enough to prevent the average troll from spinning up 50 accounts to yell into the void.-

Of course, this all raises philosophical questions. Like: should your right to privacy hinge on your desire to play Candy Crush in peace? Is a SIM card a person? Could it run for European Parliament? And should we perhaps explore more civilized alternatives to this “one phone number equals one identity” system, like zero-knowledge proofs or just asking nicely?

In the meantime, welcome to the EU: where the cheese is soft, the bureaucracy is hard, and your SIM card knows more about you than your therapist.-

Nice post, I smiled.

There are several countries that didn't buy into the madness of registering SIMs, luckily. Most strangely, the UK, the master of CCTV. Apparently they realized that it's a useless measure and will just anger the people.

... And SIMs are available from vending machines, which I find amusing :)

Pure bullshit and trolling, you're getting off on yourself, please don't do that here.
