The term URL means Uniform Resource Locator. The only charge will come from the domain name registry service. If the domain you want is available, you can register it. Companies with registered trademarks can rightfully take ownership of a domain name that is registered with a very similar name to the trademark name. If you would like to change the listing for owner or billing information later, you can do that in your domain control panel .
Organizations generally prefer to register under .org.
However, there are no rules governing who may register a domain using these extensions. You will confirm your registration on that Web page. This is done in order to verify that this is not a false order, and that you are the right contact person. You will receive an e-mail directly from the registrar that informs you of either a successful or unsuccessful registration. In the case of an unsuccessful registration, you will not receive a bill from the registrar.
