I got this from that number:

Send this text to verify your mobile number. Standard SMS rates apply. (NTg3ODpsd2F5bmVyb2M=)

I've had these too, to my mobile number in Israel.

I get these blank texts too! For the last few weeks. Don't get any notifications of  them - but there they will be in my text log. I tried calling the number back from my work's landline..and once I got a message saying "the person at this number is not available." The second time I got a message saying "This number has been disconnected."

I have also received blank texts from this number. I've called it back.

I get this weekly also .. seems very odd.   Not sure if they are waiting for someone to reply but I have just been deleting them.

I repeatedly receive blank text messaged from the number (786)408-8353

For the past week or so, I have been receiving blank text messages from 786-408-8353 as well.  

I have also received blank txt from this number 7864088365

I have also received blank text messages from that number & 786-408-8365,

>>> all the "reverse number sites" want your CC to charge you to sign up for service which I don't want. Wondering what this is.... (PERIOD!!!!) lol <<<

The reason this site doesn't ask for a "CC" is because we all share information here.  Obviously, we have no information on this number yet.  And a single incident such as yours from a single number could well be just a "fat finger" error.  

Since text messages usually come from cell phones, and there is no such thing as a cell phone telephone directory, even the "reverse number sites" are unlikely to have the owner of this number available for you, unless it is used in a public record or on the Internet for another reason (e.g., a tax record or a Facebook contact number).  You could just try a Google search for the telephone number.

>>> Good luck & Merry Christmas/Hanukkah <<<

Hanukkah was on Thanksgiving and has long since ended.  Saying just "Merry Christmas" this year will probably make your Jewish friends respect you more for caring enough to know that.

Received a BLANK text message from this number, all the "reverse number sites" want your CC to charge you to sign up for service which I don't want. Wondering what this is.... (PERIOD!!!!) lol

Good luck & Merry Christmas/Hanukkah
Thanks!!!!!!! dina
