Caller identified herself as being with Google Maps, which matched the caller ID, and asked me for our street address. Then she asked for me to confirm our store hours and what kind of business classification we'd come under. Exactly the information one would expect Google to need in order to confirm that our Google Map listing was up to date and that we were indeed still in business. The caller was polite, the connection was reasonable (didn't sound like a cell-phone), and after I'd provided the information she thanked me and that was it. Clearly this was not phishing by a "directory listing" scammer, which is what most calls are when someone asks me to give them our address. If you get a call from this number I'd advise answering it. It's a few seconds out of your day, but you'd spend more time than that trying to get your listing back on Google if they pull it for being unverifiable.
Correction: This person called - unable to speak discernable English - but after asking him to repeat himself several times, I was able to understand "Is this an attorney's office?" I said yes and he hung up. Extremely unprofessional if this is, in fact, Google Maps.
I don't think this is Google, it's probably a company trying to get verified addresses and phone numbers to sell as leads to companies who will call and mail you info so don't fall for it unless you want lots of sales calls. I would love to get the phone number for Google places, they messed up my account trying to charge money for what they said was a free month promotion and I've tried to contact them, after hours of research I discovered there is no way to contact them, even their email form for places says they only accept certain subjects which didn't address my problem.
My point is there is no way Google places is calling people, the way to contact Google places is a guarded secret, even other departments of Google can't give you a phone number.
If anyone calls claiming to be Google and this happens a lot, ask them to verify your account number when you log in to your Google account it shows you a Google account number. Do not give them your number ask them to tell you your account number, if it's a Google rep they will have it since they have to "verify" your account. When they realize you aren't going to fall for their crap they will hang up on you and you will be saved from hundreds of sales calls.
It's obviously Google Maps. Try calling the number back, it's a prerecorded message from Google. The phone number is from Mountain View, CA, where they are based out of.
