You can use a word or phrase as a domain name. If the domain is for a company, you might want to put your company name in the domain, this makes it easier for your customers to find you on the Internet. Although a longer domain is harder to remember, it can contain more keywords, which is important as some of the search engines use keywords in a domain name as part of the search algorithm. But be careful of domain names that are too long, it makes it difficult to remember and prone to user input mistakes. If your preferred domain name is not available, try adding a prefix, such as "my" or "the". And finally, make sure your domain name can be verbally communicated. You do not want to constantly repeat or spell it out.

All domains must be connected to a registrar, and all applications for domain names must be submitted through a registrar. The registrar also helps you with the renewal, transfer or termination of your domain name registration.

When you register your domain name, you will notice that your registrar will ask you for quite a bit of information: your name, your email address, your physical address, and your phone number. The information is used to complete two of the three registration profiles for your domain name: Registrant and Administrative Contact. Then, all three registration profiles (Registrant, Admin and Technical contacts) will be publicly available and accessible on their registry's database.

After you have chosen a domain name, you will need to submit your domain name registration request to a registrar. You will need to submit the following information to the registrar: the desired domain name The name and contact information (including email address, physical address and contact phone number) for the domain's registrant, administrative and billing contacts. the desired domain registration term payment information Once you have provided your registrar with all these information, they will then initiate the domain name registration process for you. The registrar will send your domain name request, and the contact and technical information of the domain name to the registry. The registry files the contact information for the Whois. The registry also adds your domain zone files to the master servers. These master servers tell other servers on the Internet where your website is stored. Your domain is considered registered and ready-to-use when all information has been updated.

A domain name transfer is the process of changing the designated registrar of a domain name.
There may be many reasons why you want to transfer your domain name registration from one registrar to another: pricing, domain management and administration, services, customer support, etc.
All domain name transfer requests must be initiated by the registrant or the Administrative Contact of the domain, and processed by the gaining registrar, the registrar whom you are transferring your domain to.

The end user verifies that the whois admin contact info is correct, particularly the email address; obtains the authentication code (EPP or UDAI transfer code) from the old registrar, and removes any domain lock that has been placed on the registration. If the whois information had been out of date and is now updated, the end-user should wait 12–24 hours before proceeding further, to allow time for the updated data to propagate.
The end user contacts the new registrar with the wish to transfer the domain name to their service, and supplies the authentication code. The gaining Registrar must obtain express authorization from either the Registered Name Holder or the Administrative Contact. A transfer may only proceed if confirmation of the transfer is received by the gaining Registrar from one of these contacts. The authorization must be made via a valid Standardized Form of Authorization, which may be sent e.g. by e-mail to the e-mail addresses listed in the WHOIS. The Registered Name Holder or the Administrative Contact must confirm the transfer. The new registrar starts electronically the transfer of the domain with the help of the authentication code (auth code).
The old registrar will contact the end user to confirm the authenticity of this request. The end user may have to take further action with the old registrar, such as returning to the online management tools, to re-iterate their desire to proceed, in order to expedite the transfer. The old registrar will release authority to the new registrar. The new registrar will notify the end user of transfer completion. The new registrar may have automatically copied over the domain server information, and everything on the website will continue to work as before. Otherwise, the domain server information will need to be updated with the new registrar.
