renewalmode = (NULL) | (TEXT)

Ownerchange

All contact information with the exception of registrant Name, Organisation, and ID/VAT number can be updated through the ModifyDomain command.

Please note that the registry does not support handle updates. You have to create a new handle containing the same information for Name and Organisation as well as the updated contact information and attach it to the domain with the ModifyDomain command.

command = ModifyDomain
domain = (domain)

REQUIRED

ownercontact0 = (CONTACT)

In order to change the owner you have to request a trade with the TradeDomain command. This can be done through our web interface or through our API:

command = TradeDomain
domain = (DOMAIN)

REQUIRED

ownercontact0 = (CONTACT)
X-NICSE-IDNUMBER = [DE]123456789

As Necessary

X-NICSE-VATID = DE123456789

*Before a trade gets initiated at the registry, a confirmation is required: A fax form is required by the registry to process a trade. Once confirmed then the trade is initiated.

**A Change of Registrar with the simultaneous change in the Registrant is not possible. Please be aware that domain name must be already managed by us. Further information can be found at TLD specific

Registration

Starting March 1st 2024, we will introduce Contact Verification to validate the Registrant Contact Information. Registrant Verification

Some special parameters have to be specified:

X-NICSE-IDNUMBER - This number must be provided for individuals as well as for organizations. For individuals or companies located in Sweden a valid Swedish personal or organizational number must be stated (6 digits, dash, 4 digits). For individuals and companies outside of Sweden the ID number (e.g. Civic registration number, company registration number, or the equivalent) can consist of 4 to 123 characters.

Please also note to state the respective ISO - code when submitting a registration request to our system. Example: for Germany please use [DE], for Belgium [BE].

X-NICSE-VATID - The VAT id is only required for companies that are located inside the European Union but outside Sweden.

 X-NICSE-IDNUMBER = [DE]123456789
 X-NICSE-VATID = DE123456789

By default there is a privacy protection for individual registrants in place. You can disclose the information with using the following extension:

X-NICSE-DISCLOSE = 0 | 1 

New Eligibility Restrictions for .SE

Starting on June 24, 2019 00:00 UTC, all registrants must now agree to the Registry Terms and Conditions of Registration (see below) upon new registration of .SE domain names.

X-SE-ACCEPT-REGISTRATION-TAC = 1 

Third Level Domain Names

• ORG.SE: for not-for-profit associations.
• PP.SE: only private individuals.
  The registrant must be a natural person with a Swedish personal identity number or a Swedish coordination number.
• PARTI.SE: for political parties.
• PRESS.SE: for magazines and journals.
  Registration under .PRESS.SE requires an authorization to publish issued by the Swedish Patent and Registration Office (PRV).
• TM.SE: for trademarks. (New registrations no longer accepted)
  
• County-related.
  Business enterprises may be registered under the county-related domain name (corresponding to the county's abbreviation) in the county where the applicant has its head office. For registration, the applicant must run a business enterprise and must be registered for corporate taxation (i.e. the applicant has an F-tax certificate).
  A domain name registered under the county-related second-level domain in which the operation is registered appears as follows:
  • K.SE: Blekinge County
  • I.SE: Gotland County
  • X.SE: Gävleborg County
  • N.SE: Halland County
  • Z.SE: Jämtland County
  • F.SE: Jönköping County
  • H.SE: Kalmar County
  • W.SE:Dalarna County (formerly Kopparberg County)
  • G.SE: Kronoberg County
  • BD.SE: Norrbotten County
  • M.SE: Skåne County (formerly Malmöhus County)
  • A.SE: Stockholm County
  • D.SE: Södermanland County
  • C.SE: Uppsala County
  • S.SE: Värmland County
  • AC.SE: Västerbotten County
  • Y.SE: Västernorrland County
  • U.SE: Västmanland County
  • O.SE: Västra Götaland County (formerly Göteborg and Bohus County)
  • T.SE: Örebro County
  • E.SE: Östergötland County

  There are still county domains that derive from counties that no longer exist. New registrations under these county domains are not permitted. This applies to:

  • L.SE: Kristianstad County (see Skåne County)
  • R.SE: Skaraborg County (see Västra Götaland County)
  • P.SE: Älvsborg County (see Västra Götaland County)

Deletion

Please note, that the registry will send an invoice to the owner of a domain providing him the possibility to pay the renewal fee directly to the registry. If the invoice is not paid to NIC.se the domain will be finally deleted. If the registrant doesn't want the registry to send an invoice, they have to send a completed Termination Fax directly to NIC.se.

Authorization Code

As of June 1, 2024, it will no longer be possible to set an authorization code manually. All auth codes are set by the registry. To retrieve the auth code, please use the ModidyDomain command with a random auth code. The registry will then respond with the current authorization code.

The authorisation code includes a total of 16 letters and digits separated by dashes, in the following format:

XXXX-AAAA-BBBB-CCCC

It will be valid for 14 days by requesting a new authorization code. You can generate a new authcode by removing the domain transfer lock.

OTE TLD is not .SE

.TEST is the TLD that IIS uses in their test platform. .SE is not accepted but .TEST is.

RegistrarOC

Change of Registrant (Trade)

If you are RegistrarOC customer, you have to activate pending domain trades after receiving the fax form with the ActivateDomainTrade command. As RegistrarOC customer, you have the possibility to customize our fax form with your logo and your fax number.

Restore Process

To restore a domain as a RegistrarOC customer, you simply have to execute the RestoreDomain command. HEXONET directly forwards the restore request to the registry, which performs the restore in real-time. As soon as the restore is complete, the domain will get assigned to your account with the original domain data.

Please do not initiate a restore directly at the registry (e.g. using the registrar webinterface). All restore operations must be performed through our system.
