A new service from BeenVerified.com called Number Guru lets you perform reverse phone number lookups–using a phone number to identify its source / owner. Best of all, it’s free. It can be especially annoying when you receive repeated calls from the same number. You may not want to answer a call from an unidentified caller, but at the same time you may be very curious about who is being so persistent about getting a hold of you. Number Guru can be used from the NumberGuru.com Website, and is also available as an app for iPhone / iPod Touch, and Android, with a BlackBerry version coming soon. Users can enter comments to share with other Number Guru users to help expose telemarketing spammers or other shady calls.
Number Guru lets you perform reverse phone number lookups from your iPhone or Android smartphone. There are other reverse lookup services, but not free — they can be quite costly. For example, the Intelius reverse phone number lookup claims to be free, and it will conduct the search for free–but if you actually want to see the relevant information it will cost you $5.Whitepages.com will also do a reverse lookup search for “free”, but charges $2 if you want to have the name associated with the reverse lookup texted to your mobile phone.
