SMS Sender ID Authorisation and Registration
Under a new regulation issued by Traficom, SMS Sender IDs used in Finland must be managed on two levels:
1. Authorisation (mandatory from 4.5.2026)
All telephone numbers and named sender IDs used in Finland must be authorised by the local telecoms company.
-
Applies to all SMS sending data.
-
Ensure that the sender information is accepted and used correctly.
-
A prerequisite for the future delivery of messages.
-
Quriiri handles the authorisation of the sender IDs of its customers
2. Registration (optional)
The SMS Sender ID can also be protected by registering it with Traficom.
-
The company gets exclusive rights to that sender name.
-
No one else can use the same name to send messages.
-
The risk of abuse and scam messages is significantly reduced.
-
Your SMS provider must be authorised to deliver messages with a registered SMS Sender ID.
Quriiri helps with both the authorisation and the registration process of the sender information.

Your SMS provider is authorised to deliver messages using this sender name

Frequently asked questions about authorization of a sender ID
Can a company have more than one sender record?
Yes. For example, many organisations have a named SMS Sender ID for information messages and a numbered SMS Sender ID for two-way communication.
Can I use any name as a sender?
For each SMS message sent via Quriirin, you can set either alphanumeric (text, 11 characters) or numeric (15 digits) sender information. From 4.5.2026, the sender information must be either authorised or registered. The name must be related to the activity of the transmission.
What is the difference between authorisation and protection?
Authorisation is mandatory and ensures that you are authorised to use the sender ID/number. Quriiri will carry out the authorisation on behalf of the customer. Authentication is voluntary. By registering a consignor number with Traficom, you can protect your consignor number. The protection gives you the exclusive right to a registered nominal consignor's number in Finland.
Does the same SMS Sender ID also work abroad?
The SMS Sender ID registration process varies from country to country. Our experts will help you with both domestic and international communications.
How do I know if my sender ID will still work after 4.5.2026?
At Quriiri, we ensure that all our customers' sender IDs are in order and that messages will be delivered safely even after 4 May 2026.
