You can if you have an Androide cell phone. The App is called "tcallBlocking". There is a free version in which you can block up to 3 ph. numbers and then a full version that costs $2.00, allowing you to block unlimited numbers. I just bought the full version to use the wild card. By using the wildcard, you can block an entire area code by entering <206*>.
I have been getting the same calls from various different "206" area code numbers, so I found this App and it has been working for me.
I just received a call from this # but I did not answer. In the past the same # has called but instead of the last two prefix being 57, the lasts two prefix are 53 and 55. I can bet it's the same Telemarketer. They never leave a message.
Received several calls from this number ... the name displayed on my caller ID is IND SUR Group... I haven't answered nor have I tried returning the call. They won't leave a message when the answering machine picks up.
