Are .edu, .ac.uk and .gov emails business emails? Education and government addresses explained

Yes, in the sense that matters for most products. Schools, universities and government bodies run their own domains, so jane@university.edu or tom@agency.gov.uk is an organizational email address, not a personal one: the institution owns the domain and manages every account on it. isBusinessEmail gives these addresses their own categories, education and government, sets is_business: true for both, and allows them under every policy. The edge cases are students, alumni and contractors, where the domain proves the institution but not the person’s role.

Why institutional addresses count as organizational

The core rule for a business email is about the domain: is it the organization’s own, or shared with the public? Schools, universities and public bodies pass that test the same way companies do.

• They control the domain. Only the institution’s IT team can create an address on university.edu or agency.gov, and it can close the account when someone leaves.
• Many of the suffixes are restricted. In the US, .edu is limited to accredited postsecondary institutions, .gov to government organizations and .mil to the military. Other countries reserve second-level suffixes such as .ac.uk, .edu.au, .gov.uk or .gouv.fr for the same purpose.
• They run real mail systems, often Google Workspace for Education or Microsoft 365 Education, with admins, policies and tenants that integrations can connect to.

What differs is the relationship behind the address. A company address usually means an employee. An education address can belong to a student, a researcher, a lecturer or an administrator, and a government address can belong to an official, a contractor or a team mailbox. What is a business email? covers the definition, and business email vs personal email compares the two sides in detail.

How isBusinessEmail classifies them

There are two categories, each with its own reason code:

Category	Reason	What matches	Examples
education	education_domain	.edu; .edu.* such as .edu.au; .ac.* such as .ac.uk, .ac.jp or .ac.nz; known university domains	jane@university.edu, jane@example.ac.uk
government	government_domain	.gov; .gov.* such as .gov.uk or .gov.au; .gouv.fr; .gc.ca; .mil; europa.eu and a short list of other public-sector domains	tom@agency.gov, tom@agency.gov.uk

Three details make this work in practice:

1. Known university domains. Plenty of universities don’t use an academic suffix at all. Many European universities sit on ordinary country domains such as ethz.ch or uva.nl. isBusinessEmail includes an open list of more than 10,000 university domains worldwide, which you can download as the education domains list.
2. Suffixes match the real public suffix. A pattern like gov.* counts only when gov.xx is the registry’s own suffix, as with gov.uk. A domain someone registered with “gov” or “edu” in its name, under an ordinary top-level domain, doesn’t become a government or a school.
3. DNS checks still run. A list or suffix match decides the category, but the domain’s mail setup is still read, so workspace detection works (more on that below).

The check page for a real university shows all of this at a glance: see mit.edu. A trimmed response for a university on Google Workspace looks like this:

{
  "domain": "university.edu",
  "category": "education",
  "is_business": true,
  "is_free_provider": false,
  "recommendation": "allow",
  "reasons": ["education_domain", "mx_google_workspace", "spf_present", "dmarc_reject"],
  "workspace": {
    "google_workspace": { "detected": true },
    "microsoft_365": { "detected": false }
  },
  "integrations": { "google_workspace_ready": true, "microsoft_365_ready": false }
}

Precedence and more specific entries

When lists disagree, isBusinessEmail applies a fixed order: admin override, blocked, disposable, relay, shared, education and government, then custom domain. On top of that, a more specific entry beats its parent domain.

That matters for universities. university.edu can be education while alumni.university.edu is personal, if the alumni subdomain is listed as a shared mailbox service. The same order catches the odd free mailbox service that hands out addresses under an academic-looking name: those domains sit on the shared provider list, and shared wins over the education suffix.

If a verdict looks wrong for a school or agency, report it through the feedback endpoint. A person reviews every report before any list changes.

Policies: allowed everywhere

Address	b2b (default)	strict	lenient
education	allow	allow	allow
government	allow	allow	allow
Role account on either, such as info@university.edu or procurement@agency.gov	review	block	allow

Because is_business is true for both categories, a sign-up form that asks for a work email lets them through by default. Role accounts are the exception, exactly as on company domains: info@, procurement@ and purchasing@ belong to a team, not a person, so they land in review under b2b. Categories and policies has the full table, and reason codes lists education_domain and government_domain with the rest.

Workspace detection still works

Personal, disposable and relay list matches are answered from the lists alone. An education or government match still gets the full DNS checks, so a school on Google Workspace for Education or a ministry on Microsoft 365 shows up the same way a company does:

• workspace.google_workspace.detected from Google MX records or a Google DKIM key.
• workspace.microsoft_365.detected and the tenant_id from Microsoft’s public discovery documents.
• integrations.google_workspace_ready and microsoft_365_ready, which are only ever set for business, education and government domains.

For edtech and govtech products this is the useful part. You can pre-select the Google or Microsoft connector for a school and know before onboarding that the institution has a tenant an admin can consent for. Workspace detection explains the evidence, and the Google Workspace checker and Microsoft tenant lookup show it for a single domain.

Edge cases

Students

Student addresses are on the university’s domain, so they come back education, which is correct: the institution issued them. But a student isn’t an employee, rarely has purchasing authority, and often loses the address some months after graduating. In a B2B funnel, treat students as future buyers or research users rather than sales leads.

Alumni and lifetime forwarding

Some universities give graduates an address for life, often on a separate alumni subdomain or domain that forwards to a personal inbox. It still looks institutional, but it says nothing about where the person works now. Where such a domain is known to work as a personal mailbox, a more specific list entry classifies it as personal. Otherwise an alumni subdomain inherits the university’s education category, and a separate alumni domain is classified on its own suffix and DNS.

.edu outside the US, and schools on ordinary domains

The .edu top-level domain is essentially American. Elsewhere, universities use a second-level suffix (.edu.au, .ac.uk, .ac.jp) or no academic suffix at all, which is what the university list is for. Schools are patchier. US districts under state k12 domains such as k12.ca.us match, but many schools and districts use .org, .net or their own domain, and those come back business (or unknown if the evidence is thin). For a work-email gate the outcome is the same, because is_business is true either way. Only something like an education discount needs to look closer.

Contractors, and public bodies on other domains

Contractors and consultants often get an address on the agency’s domain so they can use its systems. The address proves access, not employment, and certainly not purchasing authority. In the other direction, many local governments, public hospitals and state-owned companies use ordinary .org, .com or country domains, so they come back business. Treat government as a strong hint for routing, not as the definition of the public sector.

When to treat them differently

All three policies allow education and government addresses, so the question is rarely “block or allow?”. It’s “which path do they go down?”

Situation	What to do
Education discount or academic plan	Offer it on category: "education", require a confirmation email, and decide up front whether staff and alumni qualify
Government buyers	Route government to a public-sector owner. Procurement usually means quotes, purchase orders, security questionnaires and contract terms rather than a card checkout
Lead scoring	Give both categories their own track instead of mixing them into the company score
Work-email gate at sign-up	Allow both, like business, and handle role accounts as review

A classifier tells you the domain belongs to a school. It doesn’t confirm that the mailbox exists or that the person is enrolled; for a discount, the confirmation email does that part. Email verification vs classification explains the split.

Routing by category takes a few lines:

async function routeLead(email) {
  try {
    const res = await fetch('https://api.isbusinessemail.com/v1/check', {
      method: 'POST',
      headers: {
        Authorization: `Bearer ${process.env.IBE_API_KEY}`,
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({ email }),
      signal: AbortSignal.timeout(2500),
    });
    if (!res.ok) return { track: 'default' };
    const r = await res.json();
    if (r.category === 'government') return { track: 'public-sector' };
    if (r.category === 'education') return { track: 'academic', eduPricing: !r.is_role_account };
    if (r.is_business) return { track: 'sales' };
    return { track: 'self-serve' };
  } catch {
    return { track: 'default' };
  }
}

Lead scoring by email domain shows a full scoring model with separate tracks, and the B2B lead qualification playbook applies the same idea to inbound forms.

Next steps

1. Decide what education and government sign-ups get in your product: the same path as companies, a discount, or a sales track of their own.
2. Store category on every lead and account so you can report on these groups separately.
3. Test the branch with education@test.isbusinessemail.com, a reserved test address that always returns education and never counts against your quota.
4. If you need the raw data offline, download the education domains list.
