Adressesperren gjelder oppholdsadressen.

Norwegian very often forms compound nouns by joining words together into one word.

• adresse + sperre = adressesperre
  literally something like address block / address protection
• opphold + adresse = oppholdsadresse
  literally residence address / current address

This is much more common in Norwegian than in English. Where English often uses separate words, Norwegian frequently combines them.

In this sentence, both compounds are also in the definite form:

• adressesperren = the address protection/block
• oppholdsadressen = the residence address

Here, gjelder means applies to, concerns, or is valid for.

The verb å gjelde is commonly used when talking about:

• rules
• laws
• exceptions
• decisions
• restrictions

So Adressesperren gjelder oppholdsadressen means that the address protection applies to the residence address.

The ending -en is the usual definite singular ending for many masculine nouns in Bokmål.

For example:

• en adresse → adressen = the address
• en sperre → sperren = the block/restriction
• en oppholdsadresse → oppholdsadressen = the residence address

Because these are compounds, the definite ending goes on the whole compound noun:

• adressesperre → adressesperren
• oppholdsadresse → oppholdsadressen

So the sentence uses the address protection and the residence address, not just an address protection or a residence address.

In Norwegian, the is often built into the noun itself as a suffix.

Compare:

• English: the address
• Norwegian: adressen

This is completely normal in Norwegian. Instead of a separate article before the noun, you often attach the definite ending directly to the noun:

• en bil = a car
• bilen = the car

So in this sentence:

• adressesperren = the address protection
• oppholdsadressen = the residence address

Norwegian main clauses normally follow the V2 rule, which means the finite verb usually comes in the second position.

Here the structure is:

• Adressesperren = subject
• gjelder = finite verb
• oppholdsadressen = object

So the sentence follows the normal pattern:

Subject + verb + object

If another element came first, the verb would still stay second:

• I denne saken gjelder adressesperren oppholdsadressen.

That verb-second pattern is a very important feature of Norwegian sentence structure.

Yes. In this sentence:

• Adressesperren is the subject
• gjelder is the verb
• oppholdsadressen is the object

In other words, the address protection is what does the action of applying, and the residence address is what it applies to.

English learners sometimes expect a preposition, like applies to the residence address, but Norwegian often allows å gjelde to take a direct object like this.

Oppholdsadresse refers to the address where someone is staying or living at the moment.

The first part, opphold, is related to:

• stay
• residence
• period of staying somewhere

So oppholdsadresse is not just any address in general. It specifically points to the address connected to where a person is currently residing or staying.

Depending on context, it can differ from things like:

• postadresse = postal address
• folkeregistrert adresse = registered address
• bostedsadresse = residential address

Yes. This sounds quite official and administrative.

Words like:

• adressesperre
• gjelder
• oppholdsadresse

are common in formal texts from authorities, public services, legal documents, or administrative systems.

A more everyday sentence might be phrased differently, but in official Norwegian this style is very natural and common.

Usually, in this kind of official phrasing, gjelder oppholdsadressen is the more direct and natural structure.

Norwegian can use gjelde for in some contexts, especially when talking about something being valid for a group or situation, for example:

• Regelen gjelder for alle. = The rule applies to everyone.

But with a direct object like this, gjelder oppholdsadressen is very natural.

So for this sentence, the version without for is the one you should expect.

Yes, this is standard Bokmål.

Everything in the sentence looks normal for Bokmål:

• Adressesperren
• gjelder
• oppholdsadressen

A Nynorsk version would likely be phrased differently, especially with different vocabulary or endings. So if you are learning Bokmål, this sentence is fully consistent with that standard.
