New ZG Link: https://www.zg.ch/behoerden/sicherhe...uskunftssperre (no english)

The link for Zurich appears to be broken...

Fixed it with the current link. Thanks for letting us know.

Unfortunately many links in the first post are broken. ch.ch has a list of their own, albeit with many broken links as well.

In short: It's a mess.

Perhaps simply search for "Sperre Halterdaten Aargau" or whichever Kanton you're in.

Thanx for sharing... Freiburg's link is dead

Aha....that explains why the woman driver was taking down my number after I told her to F##k off when she nearly rammed me and then became abusive even after I APOLOGISED for making her brake hard. :-)

Thanks. Should be updated now.

Does anyone know if you have to request it more than once? Mine was blocked but now reappears...

Did you move cantons, have a new plate, changed registered holder, or put it on hold?

Can only speak about canton ZH: Blocked it more than a decade ago. Plate was on hold for a certain time. It is still blocked and even the other, additional plate I have is also blocked without any further request.

Here is how to request it and it should "stick" according to this :

Transferring a car between partners is a common way of getting out of long insurance contracts. Did you do that ?

In Ticino phone numbers are not shown. Can't speak about other cantons.

Yes, but the phone number can be looked up at local.ch

Happened to me when I lost a plate, and the person who found it phoned me up.

Tom

I changed car and ownership of the number plate (at a cost of CHF100) with my spouse in February 2019. The number remains blocked...

Geneva is now at https://www.ge.ch/document/conducteu...ms/telecharger

Though a lot of people are no longer in the book. Young people or those who arrived in the last ten to fifteen years (and that's a heck of a lot of people) are much more likely either to have only a mobile (and no home phone) or not be in the book, or both.
Mobiles are more often than not, simply not published, particularly employee work mobiles.
Telephone directories used to be twice or three times the thickness they are now.

Thanks for this! super helpful! Is there an online form where can i upload this form for ZH? Is ZH only available for sending the forms via post?

Thanks all!
