What Is the .cpa Domain? The Verified Domain for Licensed CPAs

The .cpa domain is one of the internet's few truly restricted extensions: a credential-gated top-level domain reserved for licensed Certified Public Accountants and CPA firms. Unlike open suffixes that anyone can buy, .cpa is administered in association with the American Institute of CPAs (AICPA) and operated by CPA.com, and every registrant's license is verified before a name is issued. For accounting professionals, that verification is the entire point — a .cpa address tells clients, at a glance, that the firm behind it is a real, licensed CPA practice.

This page explains what .cpa is, exactly who can register it, how the eligibility checks work, and where it fits relative to mainstream alternatives like .com and accounting-adjacent niche options.

.cpa at a glance

What is .cpa?

.cpa is a new generic top-level domain (gTLD) delegated under ICANN's new gTLD program, but it belongs to the restricted, profession-specific category rather than the open commercial one. The AICPA was awarded the .cpa TLD by ICANN in 2019, and CPA.com — the AICPA's business and technology arm — administers and manages it. You can confirm the delegation and sponsoring organization on the IANA root-zone entry for .cpa, and the operator's own program lives at register.domains.cpa.

Because it is a generic (not country-code) TLD, Google treats .cpa as a generic extension with no built-in geo-targeting. As Google Search Central explains, generic TLDs are not tied to a single country for ranking purposes, so a .cpa name does not signal "US-only" the way a ccTLD would. The defining characteristic is the restriction itself: most extensions sell to whoever pays, but .cpa sells only to whoever can prove a CPA credential, which makes the suffix function less like a marketing label and more like a verifiable badge.

History of .cpa

The AICPA applied for and won the .cpa string through ICANN's new gTLD expansion, securing ownership in 2019. Rather than open the floodgates, the registry rolled the namespace out in deliberate phases:

• September 2020: licensed CPA firms gained access first.
• Early 2021: individually licensed CPAs became eligible.
• Later in 2021: availability expanded beyond the United States to select additional countries.

Adoption among established practices was notably strong early on. According to the Journal of Accountancy, by mid-2021 more than 6,000 .cpa domains had been registered, including registrations from roughly 90% of firms in the AICPA Major Firms Group. That concentration among large, well-known firms is unusual for a young TLD and reflects the suffix's positioning as a credibility asset rather than a speculative one.

How people use .cpa

The use cases are narrow by design, which is exactly why they are strong:

• Firm homepages that signal a verified, licensed practice (e.g. yourfirm.cpa).
• Trusted email — a name@firm.cpa address is hard for impersonators to spoof because they cannot obtain a matching .cpa domain.
• Client portals and secure document exchange, where a recognizable, restricted domain reduces phishing risk.
• Individual practitioner sites for sole proprietors and partners who hold a personal CPA license.

Who it's not ideal for: anyone who is not a licensed CPA or CPA firm — bookkeepers, tax preparers without a CPA credential, accounting software vendors, fintech startups, or international accountants outside the eligible jurisdictions. For those audiences, an open extension is the realistic choice.

Notable sites using .cpa

Because eligibility is verified, public .cpa addresses are genuine CPA practices rather than parked or speculative names. CPA.com itself runs the program's registration hub at register.domains.cpa. Rather than name specific private firms that may change their setup, the honest description is this: the active .cpa namespace is composed almost entirely of licensed accounting firms and individual CPAs, with adoption skewed toward larger, well-known practices that value the anti-impersonation guarantee.

.cpa vs other domains

Choose .cpa when you are a licensed CPA and want the verification badge and anti-impersonation protection. Choose .com when you want the most universally recognized address and do not need a credential signal. Choose an open accounting-themed extension when you want topical relevance but are not (or do not want to gate on being) a licensed CPA.

Why choose .cpa?

• Verified credibility. Every .cpa registrant has had their CPA license checked, so the suffix is a built-in trust signal no open TLD can replicate.
• Anti-impersonation by design. Fraudsters cannot register a lookalike .cpa domain to mimic a real firm, which closes a common phishing and "imitator domain" vector.
• Professional clarity. The name says exactly what the business is — a CPA practice — without extra words.
• A cleaner namespace. Because the pool of eligible registrants is small, sensible firm names are more attainable than on saturated .com.

Things to consider

• You must qualify, and stay qualified. This is the central trade-off: if you are not a licensed CPA or CPA firm, you simply cannot register, and you must remain eligible to renew.
• Limited geography. Eligibility currently covers the US, Canada, and Ireland — practitioners elsewhere are excluded.
• Verification takes time. Registration is not instant; the registry validates your license and identity, which can take from hours to longer depending on available data.
• Lower public recognition. General consumers still expect .com, so some firms run .cpa alongside a .com they already own.

Who can register a .cpa domain?

Registration restrictions (read this first): .cpa is credential-gated and restricted. To register, you must be either (i) a licensed CPA firm holding a CPA firm license issued by a state board of accountancy, or (ii) an individual holding a CPA license. Availability is limited to United States, Canada, and Ireland based applicants. Crucially, eligibility is verified at the time of purchase and again at every renewal — this is not a one-time check. The registry, operated by CPA.com in association with the AICPA, monitors ongoing compliance, and an inability to demonstrate a valid license at renewal can prevent you from keeping the name.

The verification covers both your CPA credential and your identity, so applicants should expect a review window rather than instant activation. The authoritative rules live on the registry operator's own .cpa eligibility FAQ. As a restricted new gTLD, .cpa is governed by an ICANN Registry Agreement and standard policies; DNSSEC is supported, and the restricted nature of the namespace means lookalike and abusive registrations are structurally prevented rather than merely policed after the fact.

.cpa pricing and value

.cpa is a specialty, verified TLD, and that shapes its pricing dynamics (this page never quotes actual numbers). Expect it to sit well above commodity open extensions, reflecting the cost of identity and license verification rather than a generic registration. As with most TLDs, first-year and renewal pricing can differ, and the renewal price — not the introductory one — is what matters for a long-held firm identity. There is generally no large speculative premium-name market here, because the namespace is restricted to eligible professionals rather than open to investors. The real "value" calculus is qualitative: you are paying for a verified credential signal and impersonation resistance, not for a tradeable asset.

Reputation and email deliverability

.cpa enjoys an unusually strong reputation for a young TLD precisely because it cannot be bought by spammers or impersonators. A restricted, license-verified namespace is the opposite of the cheap, high-volume TLDs that mailbox providers learn to distrust, so a @firm.cpa sending domain starts from a position of credibility rather than suspicion. As always, deliverability still depends on correct configuration: publish SPF, DKIM, and DMARC records, warm up new sending domains, and follow normal email hygiene. The suffix gives you a clean reputation to build on, but it does not exempt you from authentication best practices.

Branding and naming tips

• Lead with your firm name: smithcpa.cpa is redundant; smith.cpa reads cleanly and lets the suffix do the work of saying "CPA."
• Mind the read-aloud test: "smith dot c-p-a" is clear over the phone, which matters for a profession that still does a lot of business by voice and referral.
• Avoid confusing constructions that bury the dot inside a word; the strength of .cpa is that the credential is obvious, so don't obscure it.
• Consider a defensive .com if you have one, and point it at the .cpa site, so clients who type the familiar extension still reach you.

Frequently asked questions

Can anyone register a .cpa domain?

No. .cpa is a restricted, credential-gated TLD. Only licensed CPA firms and individually licensed CPAs based in the United States, Canada, or Ireland may register, and the registry verifies your CPA license and identity both at the time of purchase and at every renewal.

Does a .cpa domain affect SEO?

A TLD choice is not a direct Google ranking factor, so .cpa neither helps nor hurts rankings on its own. Its real value is trust and credibility: a .cpa address signals a verified accounting professional, which can improve click-through and reduce impersonation risk.

Who should register a .cpa domain?

Licensed CPA firms and individual CPAs who want a verified, profession-specific web and email identity. It suits practices that value anti-impersonation security and a credential signal more than a short, generic name.

What happens to my .cpa domain if my CPA license lapses?

Eligibility is re-checked at each renewal. If you can no longer demonstrate a valid CPA license or firm license, you may be unable to renew the domain, since the registry validates eligibility on an ongoing basis rather than only at first purchase.
