These are temporary finnish phone numbers or also called finnish numbers. This means that they are only available for a short period of time. Some finnish phone numbers last for several months, others only a few days.
Please do not use such a finnish number for important text messages such as passwords, private text messages to friends or for phone verification on websites. Anyone could take over your account by reading the text messages of these finnish phone numbers.
If you do not live in finland and still want to use a particular site or web that only accepts finnish users, it is necessary to have a finnish phone number to verify your account.
Most websites that require phone number verification have a limit on how often you can use a phone number. In this case it can happen that some of our finnish phone numbers are blocked. But this is not a big problem. Just use one of our other finnish phone numbers.
