Every telephone number will have a respective online directory. This directory will also provide the CID information. To do a number lookup, one will simply enter the phone number followed by tel.ka. In example, John Smith’s number is 412259329560, and therefore – his telephone directory will be https://412259329560.tel.ka From there, any contact information (minimum name and number) of John Smith can be found there. He can make changes, and add entries through the online portal. This directory will behave similarly to a .tel domain.
