Domain names play a crucial role in establishing an online presence, the introduction of the .PRO generic Top-Level Domain (gTLD) marks a significant milestone for professionals worldwide. This article delves into the .PRO domain, exploring its purpose, potential applications, and the unique opportunities it offers to professionals across various industries.

What is the .PRO Domain?

The .PRO domain is a gTLD specifically designed for professionals and professional entities seeking to highlight their expertise and credentials on the internet. Launched to provide a distinct online space for certified professionals, the .PRO domain caters to individuals, businesses, and organizations across a broad spectrum of professional fields. From lawyers and doctors to architects and accountants, the .PRO domain offers a platform to showcase professional services and grow trust with clients and colleagues online.

According to some sources, there are around 500,000 .PRO domain names registered. It’s a similar size to .CLUB, which we covered in our recent research.

A generic Top-Level Domain (gTLD) is a category of domain names in the Domain Name System (How DNS works) of the internet that is used globally. Unlike country-specific top-level domains (ccTLDs) that are tied to a particular country or region, gTLDs are generic and can be registered by anyone, anywhere in the world. Examples of gTLDs include .com, .net, .org, and newer additions like .pro, .club, and .tattoo. These domains serve various purposes, from representing commercial businesses (.com) to non-profit organizations (.org), and offer a wide range of options for individuals, businesses, and entities looking to establish an online presence. The introduction of new gTLDs has expanded the internet’s naming system, allowing for more customized and descriptive domain names.

Registration and Management

The .PRO domain was managed by Registry Services, LLC until Identity Digital acquired .pro. Registry Services continues to operate .bank and . insurance. While the .PRO domain now runs under Identity Digital.

.Pro was initially restricted to licensed professionals, but it has since opened up, allowing a broader range of professionals and entities to register their domain names under this extension, provided they meet the verification criteria set forth by the registry.

Altough the recent explosion of new gTLDs would led you to believe .PRO is a new domain extension, that wouldn’t be true. .PRO domain was originally started in June 2004!

Whois .PRO

WHOIS is an essential tool in the digital domain landscape, serving as a protocol for querying databases that store the registration information of domain names. This system provides public access to data on registered domains, including the names of domain owners, their contact information, registrar details, domain status, and important dates such as registration and expiration. WHOIS databases play a crucial role in maintaining the transparency and security of the internet’s naming system, allowing individuals and organizations to ascertain ownership details for various purposes such as domain purchase inquiries and legal issues or to combat spam and fraud.

The management and provision of WHOIS services for the .PRO domain are overseen by Identity Digital, a specialized entity responsible for the registry operations of the .PRO gTLD. As a guardian of .PRO’s registry, Identity Digital ensures that WHOIS information for .PRO domains is accessible to the public, adhering to policies set forth by the Internet Corporation for Assigned Names and Numbers (ICANN). ICANN’s regulations mandate that registrars and registries provide up-to-date and accurate WHOIS data, contributing to a trustworthy and secure online environment.

Identity Digital (through Afilias, as you will see from example below) operates the WHOIS database for .PRO domains, facilitating a platform where users can perform searches to retrieve information about domain registrations under the .PRO extension. This service is instrumental for professionals and entities looking to establish or verify the digital identities associated with .PRO domains bolster the domain’s reputation as a trusted marker of professionalism on the internet. Through the WHOIS system, the .PRO domain maintains its commitment to transparency, allowing for the verification of professional credentials and the integrity of the domain’s users.
