You can also block an entire prefix (e.g., +33). Every number beginning with that prefix (+33123456789, +33456789012, etc.) is then blocked from both receiving and making calls.
Need to block many numbers at once? You can add them in bulk instead of entering them one by one — paste or import a whole list in a single action.

​
Managing Blacklisted Numbers

All blocked numbers appear under Blacklisted Phone Numbers, with a counter showing how many are stored.
