The Internet uses a standard domain-name system (DNS). This system uses various tiers of domains to establish unique domain names. Every domain name has what is known as a top-level domain. This is the first component of any domain name. The most popular top-level domain is .com. However, others exist, such as .edu and .biz. Another popular top-level domain is .org. There are no restrictions on who can register it, though it is popular among organizations.

Step 1

Locate a domain name registrar. These are companies that provide the service of registering domain names for their clients. Popular registrars include Go Daddy and Network Solutions (see Resources section). Although each registrar's site interface is slightly different, the process of purchasing a domain name is usually similar.

Step 2

Type your desired domain name in the field provided on the registrar's homepage. You will want to specify that you are searching to purchase a .org site. You may have to specify by either typing the .org extension or selecting it from a drop-down menu. This will determine if your desired domain name is available.

Step 3

Select to continue to registration if your domain name has not been claimed. If your desired domain name has been claimed, you will need to type in a different name until you find one that has not been claimed. Often, domain-name registrars will provide available variations of your desired name if the name is already taken.

Step 4

Create an account on the registrar's site. Usually, you will need to include your name, email address, a physical address and sometimes a phone number. You may also be asked about purchasing additional products and add-ons for your domain name. You can either choose to accept or deny these offers.

Step 5

Enter your payment information. The cost of a .org domain name will vary from registrar to registrar, but usually a .org domain is slightly cheaper than a .com. Click the "Checkout" button or "Purchase" button to finalize your purchase. Your credit card will be charged.
