  1. Been verified is not actually free. That is false. They want you to sign up for a “free 7 day trial” before they give you the “free” info. Just FYI! ?

  2. SpyTox seems to be the best of the lot. It did find a cell number other services didn’t find, and it did actually return some free information.

  3. There really is no such thing as really good and accurate free reverse phone lookup. It cost a fortune to buy, update, and store all that data. No one is giving really good data away free forever. If you don’t want to deal with subscriptions or only need a few a month, head over to searchbug.com/tools/reverse-phone-lookup.aspx. Their Current Phone Owner report is great but the detailed History report is amazing, and you can get your first one free, but they are only like a buck or two anyway and you can get a discount when you purchase their Search Tokens and even those are cheap.

  4. Instant Checkmate is not free either if all you want is to identify owner of a phone number. Charge is currently $5.99. It requires payment before it will release the “report” which provides additional info including previous address, relatives, possible court records.

  5. Zaba and ReversePhoneLookup are not legit. They both take you through the same several screens before requiring that you provide name and email address before going any further.

  6. Zabasearch is not free. It requires you to register and then will not give you any information unless you give them credit card information.

  7. Sites I’ve used for years now either don’t give free info anymore or default to Intellius, a pay service. Of the companies on this old article I DID find 2 I never knew of that work as of 3/11/2021: zlookup and usphonebook. And about a week ago I noticed that my phone company – Verizon – used to give names to the caller ID’s, but now I seem to get a lot of “Unknown name” for names that used to show up on the caller ID

  8. Yes, a reverse phone search allows you to get the details of a landline or cell phone owner. Glad I Know now offers a free reverse phone lookup service. It’s a simply enter the phone number you’re looking for.
