I think it is a routing number in Metro Vancouver, BC for overseas calls. I just received a genuine call from my friend's land line in El Salvador, Central America to my cell phone in Vancouver and it showed (604) 628-2598.

"Raul Mera" calls me from this number he claims to have a suite available for rent in north vancouver. He is requiesting 3 payments of $1050 and yes he lives out of the country for work so when he gets the payments he'll send me the keys via fed ex...wah wah wahhh

He said online prescriptions

I had a missed call from this number recently and the caller stayed on the phone leaving a message without talking. You could hear people speaking in Chinese in the background. For some reason, I thought this call was a little odd. So, if they call again I will ignore there calls.

I've just started being bombarded with nuisance calls in the last week, including this no. They all started right after I place a few ads on Craigslist. When I did a quick search of one of the numbers, up came a Craigslist ad listed by someone selling something from a basement suite in North Vancouver. I have never picked up, but it's really annoying. Yesterday I received three calls, back-to-back. As it happens, I just sprained my foot, so hobbled to the phone three times. This number (604) 628-2598) was call no. 3. A minute before that was a "blocked" call and a minute before that was (604) 678-9476 (a cursory search revealed that the latter no. was known to RCMP and could be reported to RCMP Phone Busters at 1-+1 888-495-8501), which I promptly did. Reason would dictate that all three calls came from the same person/people.The RCMP told me to just not pick up. Today I blocked (604) 628-2598, but I'm sure they'll keep calling from the "blocked" and other numbers. I have better things to do with my life than dodge calls from scam artists, add to my "blocked" list, and sit around on hold for half an hour waiting for RCMP Phone Busters. There needs to be more energy and funds directed to protecting the public and maybe a little less to furthering technology right now. It's intrusive, violating and stressful.

I am in Canada. My boyfriend is in the US. When he calls me through most calling cards, it comes up as this number. (Especially when he uses Clear choice or Centsible.)
