Prefix 600 — page 5
The 600 prefix opens Spain's mobile range and is one of the oldest and most widespread, so it appears on long-standing personal lines as well as commercial campaigns. Precisely because of that volume, 600 numbers are among the most affected by telemarketing and by spam calls trying to blend in as an ordinary mobile. A call from an unknown 600 number could just as easily be a legitimate contact as an automated campaign, so the best defence is to check the number before calling back. See the community reports below for this specific number.
