What Rates Are Possible on a 0900 Number?
As the owner of a 0900 number, you determine the rate the caller must pay. You have complete freedom in this, subject to a few legal rules and restrictions.
These rules and restrictions are mainly in place to ensure that callers have a clear and transparent understanding of what they will pay for calling a 0900 number.
What types of rates are possible, and what are the limitations?
Rates Per Minute or Per Call
Rates are charged per minute or per call.
For both types, a maximum amount applies.
Maximum Rates for 0900 Numbers
There is no minimum rate for 0900 numbers. You can also set a 0 rate (free for the caller).
The current maximum rates for 0900 numbers are:
- €1 per minute
- €1.60 per call
You cannot charge the maximum amounts for every service. More information about this can be found on the website of the Authority for Consumers & Markets (ACM).
Rates can be set in increments of €0.05. To get an idea of the available rates, take a look at the rate calculator on our 0900 number page.
