How much does it cost to call an 088 number?

You pay the same rate for a call to an 088 number as for calls to geographic numbers. So regardless of whether the holder of the 088 number is in Venlo or in Alkmaar, you always pay the same (relatively low) rate.

Since July 1, 2013, the costs for a call to an 088 number have been aligned with the calling costs of other landline numbers.
