Is There a Difference Between an Unlisted and an Unpublished Number
The simple answer to that question would be no. The terms unlisted number, non-published number, non-pub, and unpublished number all pretty much refer to the exact same thing.An unlisted number usually refers to a telephone number that has not been listed within a directory assistance list. Non-published numbers are those that have not been listed within a phone book. Therefore, when you see these terms, you can be assured that they simply have not been listed within the local telephone directory and that you likely will not be able to find them by calling 411 (directory assistance). Nor will you be able to locate the number by speaking to phone operators by dialing 0 or 00. Furthermore, this will mean that indeed, if you use a reverse telephone search service online, you will not be able to obtain the associated name and address to the telephone number.
In such a case, you will likely need to hire a private investigator in order to discover an unlisted number or to find out to whom an unlisted number belongs.
You may find, though, that many reverse search sites will simply say that a telephone number is unlisted or unpublished when it is, in actuality, a cellular phone number or a pager. Therefore, before you go to more extreme measures to discover the owner of a telephone number, you may wish to check with a few cellular phone directories, or see if you can hire an inexpensive reverse cell phone number service to try to get the number that way, first. This is because a reverse cell phone search is a great deal less expensive than a private investigator and is therefore well worth the try.
If you haven"t had much success in your search you can try to , find the owner of most landlines and cell phone numbers with this.
