866-864-5841 / 8668645841

I just received a phone message from the same number (866-864-5841). The person claimed to be calling from Revenue Canada regarding an "important matter" but he did not leave his name and I could not find that exact number listed on Revenue Canada's website. The caller requested that I phone back and have my SIN number ready to give them and that I could speak to any of the agents who answered. Mmmm....I don't think so.

I had the same massage, but on the page renevue canada there not this number, weird?

I too received the same message and ingored as I was not about to give out my SIN to just anyone. My husband had to call Rev Canada on another matter, so I spoke with the same lady he did. She said there was no record on my file stating they needed to speak with me. I gave her the phone number that was left on my machine and she said that they don't even have that telephone number on file, she also said that whomever calls from Rev Canada always leaves their name. She agreed that it was a smart move not to return the call. Now I just tried to call the number, it says "Welcome to Canada Revenue Agency, for safety reasons your call may be monitored", then the phone started to ring . As my husband mentioned, CRA always provides various options prior to you actually getting through to an agent. I think I'm going to shoot an email to the police!

Just got a call from this # and he wanted to make sure he was talking to the person he asked for, and asked for address and DOB. When I told him I'd give my address but not my DOB he told me to call 1 800 OCANADA. To which my reply was how do I know they are who they say they are.Did a google search on the OCANADA # and it goes to the Goverment web site so now what?BTW he never left his name.

I agee-I got the call too and confirmed with CRA that this is a fraud as there wasnt an record on my file for a call. I am reporting this as a fraud at a number provided by CRA

We've got a same message at home saying "This message is from Canada Revenue Agency. Please call back at 1-866-864-5841 as soon as possible since this call is very important. When you call back, please ensure you have your social insurance number with you. Our office is open Monday through Friday, and our agent will be happy to assist you."I dialed this number curiously, and there was a greeting saying that "This is Canada Revenue Agency and this call may be monitored", but no French. The lady who picked up the call asked me to provide my social insurance number. I said I don’t normally provide my SIN number on the phone. She said if you want to check out, please call 1-800-622-6232 which is the Ocanada #. So… The same story…According to your advice, I think I should stop here and hope Canada Revenue Agency doesn't have anything important to me.

thanks to hmmmmmm. Read this too! and email phonebusters. They are the canadian mounted police task force for fraud.

I have received a call telling me to contact the NS Government for a very important matter, no name was left for me to contact, and no reference number. I returned the phone call and was placed on hold with a message "please note your call will be monitared for quality assurance". When a women answered she was very short and asked me for my client ID number or SIN. I replied with "I do not give my SIN over the phone", she then snapped and said "Well then I can't help you", my reply was "you are the ones that called me" her reply was "If you don't give me your SIN then I can not help you" and she hung up on me! DEFINETLY A SCAM!!!! NEVER GIVE YOUR SIN OVER THE PHONE!

If canada rev was was calling you!!! It would be just that. Nothing after the title eg. AGENCY. This is a collecting agency nothing more. They will say they will taske you to court all that jazz they cant do crap...your friend ...XDRTX

I called Service Canada and they confirmed that this phone number does belong to Revenue Canada....hope this helps:)
