For those users who are seeking to register a country-specific domain name option (like “.us” or “.co.uk”), a good portion of the registration process will be dedicated to determining whether or not the customer is a resident of that country and therefore legally permitted to purchase one of its country-specific top level domains (will talk about this later). And that should hammer home a secondary point to users.
ICANN publishes the complete list of TLD registries and domain name registrars. Registrant information associated with domain names is maintained in an online database accessible with the WHOIS protocol. For most of the 250 country code top-level domains (ccTLDs), the domain registries maintain the WHOIS (Registrant, name servers, expiration dates, etc.) information.
Many services offer a low "starting price," but require you to prepay for two or three years of service to get that price. After the promotional period, the renewal price for some services can be two, three, or even four times the initial promotional pricing. While the initial deal might be incredible, the cost of transferring your site (or paying the added fee) in a couple of years may be something to consider.
