Hide Caller ID In Spain

Block Caller ID

It seems that many people have inquired about how to hide their number when making telephone calls within Spain. It’s very easy to do.

For mobiles, there is normally a  permanent option normally via a menu section to hide the caller ID (“Ocultar Número” or “Envío ident. llamante” if your phone is in Spanish). If you just want to hide the number before a particular call, then dial #31# before the number you want to dial on your mobile.

For landlines, simply dial 067 before the number you want to call and your number will be hidden. Simple!

I hope this helps. I have tried this with a mobile phone on the Orange network and it works just as well.
