Real-Name Registration

Anyone who signs up for a social network usually provides a username — which doesn’t have to be the real one. Real-name registration turns this around: platforms or states require users to provide their true identity, often verified through an ID card or a phone number registered under the real name. The goal is traceability. If someone writes or posts something, they should be identifiable if needed — for the platform, for authorities, or for both. Countries like China and South Korea have enshrined such requirements in law; in Europe, the discussion is lively, but no comprehensive law is yet in force.

Why real-name registration is politically explosive

Online anonymity protects people in certain situations: whistleblowers reporting wrongdoing, politically persecuted individuals in authoritarian states, or young people wanting to talk about sensitive topics. Those who have to write under their real name tend to write more cautiously — some call this self-censorship. Proponents see exactly this as an advantage: less insult, less hate speech, less coordinated disinformation.

So the tension is real. More accountability almost automatically means less anonymity protection. Which side weighs more heavily depends heavily on the political system. In a constitutional state with an independent judiciary, the risk of abuse is lower than in a country where authorities specifically persecute opposition members.

How real-name systems are implemented technically

The most common method is linking to the mobile phone number. Anyone buying a SIM card must, in many countries, show ID anyway. The platform requires a phone number for confirmation, and authorities can, if necessary, ask the network operator who owns that number. A second method is direct ID verification: users photograph their ID card and upload it. Third parties — often specialized service providers — verify its authenticity.

Both methods create a database linking real names to online activities. This is exactly the security problem: if this database is hacked, the identity of all users is compromised at once. South Korea abolished its original real-name requirement for internet platforms in 2012 partly for this reason — following a massive data leak affecting millions of users.

Platforms can also rely on softer procedures, such as uploading a selfie combined with an AI-supported age estimation process. This doesn’t verify the name, but at least roughly checks the identity. These intermediate solutions are technically complex and legally controversial.

Real-name registration in the current debate

The term comes up regularly when platforms are criticized over hate speech or disinformation. In Germany, politicians called for a real-name requirement for social networks following several attacks in which the perpetrators had previously become radicalized online. The EU-wide Digital Services Act (DSA), which has fully applied to large platforms since 2024, obligates providers to greater transparency and accountability — but does not mandate real-name registration.

In China, the system is the most developed. Anyone posting on platforms like Weibo or WeChat there has had to have a verified real name on file for years. Authorities can request information at any time. Critics see this as an instrument of political control, not a measure against crime.

For users in Germany today, real-name registration is primarily an everyday matter on gaming platforms or financial services — there it’s simply called KYC, short for “Know Your Customer,” meaning identity verification as part of anti-money-laundering efforts. The difference: with KYC, the real name typically stays internal and doesn’t appear publicly on the profile.
