SMS sender names in Denmark: rules and tips
What an SMS sender name may contain, whether it must be registered, and why recipients cannot reply to it.
The sender name is what recipients see instead of a phone number — for example SalonNord or Webshop.dk. It makes it more likely the message is read rather than taken for spam.
The rules
- Up to 11 characters.
- Letters A–Z, digits, space, dot and dash. Æ, ø and å are written as ae, oe and aa.
- At least one letter — a name with only digits is treated as a phone number.
Does it have to be registered?
Not for Danish mobile numbers. In JaSMS you add the name in the portal and use it straight away. Names that resemble banks, authorities or known brands are checked by us first — that protects recipients and you from misuse.
Can recipients reply?
Not to a text name — it is not a number. If customers should be able to answer, send from a number: your own Danish number or the shared reply number. Replies land in your inbox.
Several names
With several shops or projects, each API key can have its own sender name, and the account has a default.
