What Is the .aig Domain? AIG's Brand TLD Explained

The .aig domain is a closed brand top-level domain operated by American International Group, Inc. (AIG), a global insurance and financial-services company. It is not a public extension: unlike .com or .io, you cannot register a .aig name for your own project, because the entire namespace belongs to one company.

If you searched for the ".aig domain" hoping to buy one, the short answer is that you can't — but this page explains exactly what .aig is, who controls it, why a company runs its own TLD, and what you can register instead.

.aig at a glance

What is .aig?

.aig is a generic top-level domain that ICANN delegated to American International Group, Inc. as part of its New gTLD Program. The three letters are the company's own name: AIG is short for American International Group, a global insurance and financial-services company.

But .aig is a brand TLD — often called a "dot-brand" — not an open extension anyone can buy into. The company applied for the string specifically so that it, and only it, would control every domain ending in .aig. You can confirm the delegation and operator on the authoritative IANA root-zone record for .aig.

History of .aig

.aig was delegated to the DNS root zone on April 9, 2015, during the same wave of ICANN's New gTLD Program that brought hundreds of corporate names into the domain system. GoDaddy Registry runs the technical back-end on AIG's behalf, operating the infrastructure that keeps the namespace resolving and secure, while American International Group, Inc. remains the registry operator of record.

Its registry agreement with ICANN includes Specification 13, the contract clause that formally designates a TLD as a brand and lets the operator keep it closed. The record has stayed active since delegation, unlike several brand TLDs that were later handed back and removed from the root.

Is .aig available to register?

No. .aig is a closed brand TLD, so there is no open registration and no registrar — including Namefi — can sell you a .aig name. Registrations are limited to AIG and organizations it authorizes, such as subsidiaries or partners. This is by design: a dot-brand exists precisely so the trademark holder controls the whole namespace and no one else can register a confusing or malicious lookalike.

If you have a genuine business relationship with AIG and a legitimate need for a .aig address, that request would go through AIG's own corporate channels, not a commercial registrar.

How AIG uses .aig

Brand TLDs give a company a private space to organize its web presence. Typical uses for a dot-brand like .aig include:

• Product and division sites on clean, memorable addresses tied directly to the brand.
• Campaign and event pages that are obviously official because only the company can create them.
• Internal tools and portals where a branded suffix signals a trusted, first-party destination.

Who it's not for: anyone outside AIG. Because the namespace is closed, there is no scenario in which an independent developer, investor, or business can build on .aig.

Notable sites using .aig

There are no third-party sites on .aig, and there never will be while it stays a closed brand TLD — every .aig address is controlled by American International Group, Inc. AIG continues to run its public presence from its long-established .com domain, aig.com, and uses the brand TLD selectively rather than as a wholesale replacement. Rather than point to a specific address that may change, the honest description is simple: .aig is AIG's private namespace, used only for the company's own properties.

What is a dot-brand TLD?

A dot-brand (or brand TLD) is a top-level domain that a single company owns and operates for its exclusive use, secured through ICANN's New gTLD Program. Financial and insurance groups were among the many large corporations that applied for their own name as a TLD, and dot-brands share a few defining traits:

• Closed registration. Only the brand and its affiliates can hold names.
• Specification 13. A registry-agreement addendum that formally recognizes the TLD as a brand and relaxes some rules that apply to open generics.
• Security and control. The brand eliminates the risk of anyone else registering a .aig lookalike, which strengthens resistance to phishing and impersonation.

Some brands invest heavily in their TLD; others register it defensively and barely use it. A number of companies have even terminated their dot-brands after deciding the upkeep was not worth it.

.aig vs open domain alternatives

If your goal was a short, brandable name rather than the .aig string specifically, an open extension is the right tool. Here is how a closed brand TLD compares with domains you can actually register:

For your own venture, a matching .com remains the safest default; .io suits technical products; and .xyz is a flexible, low-cost modern option.

Reputation and trust

Ironically, the closed nature of .aig is exactly what makes it trustworthy: because only AIG can create these addresses, a .aig link is verifiably official, which is why brand TLDs are considered strong against impersonation and email spoofing — a meaningful benefit for a financial-services brand that scammers regularly try to imitate. That trust, however, benefits AIG alone — it does not transfer to any name you might register, since you cannot register one. For your own project, deliverability and reputation will come from a well-configured domain on an open extension, not from a brand TLD you don't control.
