General Information

Changes to renewal dates for .CH and .LI domains as of March 3, 2016

Currently .CH and .LI domains show a discrepancy in renewal dates depending whether they have been registered in our system or have been transferred in from another registrar. This leads to renewal dates that have different time spans in relation to the Expiration Dates.

In general, renewal dates are calculated basing on the creation date - the point in time of a successful registration: Renewal Date = CreationDate + [period] Years - 1 Day to cover any eventualities. For most TLDs this is no problem since registries are calculating expiration dates using the same scheme: CreationDate + [period] Years.

The .CH/.LI registry differs from this scheme: expiration dates are always at the end of a month: ExpirationDate = End_of_month(CreationDate)+ [period] Years i.e. 2015-01-31, 2015-04-30, etc.

We would like to change the scheme in our system by calculating renewal dates for .CH/.LI domains based on the expiration date that is retrieved from the registry. Only the renewal date will change, the date on which our system will charge the renewal.

Current state for .CH/.LI domains:

Creation date 2014-12-10 (Registration in our System)
Expiration date 2015-12-30 23:00:00 UTC (Date coming from Registry)
Renewal date 2015-12-09 (Date is calculated by our Metaregistry:
Creation Date + 1 Year - 1 Day to cover any eventualities)

Creation date: not existing, cannot be retrieved from Registry
Expiration date 2015-01-30 23:00:00 UTC (Date coming from Registry)
Renewal date 2015-01-29 (= Expiration Date from Registry - 1 Day to cover any eventualities)

In future, the renewal date for .CH/.LI domains registered in our system will be calculated as follows:

Creation date 2014-12-10 (Registration in our system)
Expiration date 2015-12-31 23:00:00 UTC (Date coming from Registry)
Renewal date 2015-12-30 (= Expiration Date from Registry - 1 Day to cover any eventualities)

For incoming transfers no changes apply.

The change will be implemented in our live system on March 3, 2016 (13:00 UTC). We do not expect any unavailability. However, we schedule one hour of maintenance work for .CH/.LI domains.

Domain Registration

.CH domains can be registered online through webinterface or API.

command         = AddDomain
domain          =
period          = 1
ownercontact0   = ....
admincontact0   = ....
techcontact0    = ....
billingcontact0 = ....
nameserver0     = ....
nameserver1     = ...
Attention.png We would like to point out that although there is no local presence requirement for .CH domains in the proper meaning of the word, the registry may in certain cases request the disclosure of a valid correspondence address in Switzerland for purposes of the direct delivery of correspondence. In these cases the registrant must provide a valid Swiss correspondence address within 30 days (date of receipt by SWITCH). If the registry does not receive details of a genuine and accurate contact address in Switzerland within the specified deadline, the respective domain name may be deleted. We added a reference to the .CH & .LI Appendix clarifying this requirement.

Domain Modification


A change of ownership can be accomplished with the TradeDomain command or webinterface and is free of charge.

command       = TradeDomain
domain        =
ownercontact0 = [new owner contact]

Domain Renewal

As .CH domains can only be registered on a yearly basis, they cannot be renewed explicitly. To renew a .CH domain, you have to set the domain renewal mode or default renewal mode to "AUTORENEW" or "RENEWONCE".

Deletion Process

.CH Domains can be deleted online through the Delete Command.

command = DeleteDomain
domain  =
Attention.png Please note that you're only allowed to delete .CH domains if you have the authorization of the domain owner. Therefore you can download a document here. Please keep this document as proof.


Only a fixed number of nameservers can be given with the registration: none, 2 servers, 3 servers or 4 servers


.CH Transfers are possible. Upon a succesful transfer the registration period is not changed.

Transfer Procedure

The only thing you need to do is requesting the transfer using the webinterface or api.

command = TransferDomain
domain  =
auth    = [authcode]
action  = request

Transfer notes

  • Transfer has to be requested with a so called authorization code.
  • The status "serverTransferProhibited" will be set for a period of 60 days after a successful .CH transfer.
  • The transfer must be allowed at any time to registrants and the handing over of the necessary transfercode shall not be withheld (Art. 20 Abs. 2 VID).
  • This applies even if customer has unpaid bills

Transfer time

A transfer of a .CH domain will usually be processed within 2 hours.


Restores are possible within 40 days upon deletion. A restore can be requested via API command or via webinterface.

command = restoredomain
domain  =
