Companies Using Amazon Business

Most of what an organisation buys never shows up from outside. Amazon Business leaves one public trace, and it comes from a governance feature rather than from buying. An administrator who wants control over every Amazon Business account on the company's email domain has to verify that domain, and doing it by DNS publishes a TXT record, amazon-business-verification plus a code. Amazon describes the steps on its Account Authority page: verify the root domain, then route new sign-ups with a work email through the company's approval process and consolidate the accounts already on it. Our October 2026 crawl finds the record on 8,962 domains. We matched 7,645 of the 9,011 in our clean live set to a company, an 84.84% match rate, which is what you'd expect when the domains belong to operating organisations.

What the record proves

It proves an organisation has an Amazon Business account and decided to govern it centrally. It doesn't measure how much the organisation buys, and it misses the far larger number of accounts that never verified a domain. Amazon says it serves more than 11 million organisations, so 8,962 domains is fewer than one in a thousand. I checked from the other side too. Fresno Unified School District, Nebraska Medicine and poppi all appear in Amazon's customer stories, and none of their domains publishes the record.

Sales signal: these rows beat a generic "buys on Amazon" list. Someone in finance or IT made purchasing policy a project, and that person is the buyer for procurement, spend-management and identity tools.

Growth trajectory

The chart reads 7,087 domains in June, 8,194 in July, 8,328 in August, 8,777 in September and 8,962 in October, a 26.46% rise in four months. Amazon reports 1.8 million new organisations in the first half of 2026, but our line can't separate real growth from our own coverage. The set of domains we crawl turns over every month, with dead domains dropping out and new ones added, and our detection widens over time, so a count like this climbs even when nothing changes at Amazon. The step from June to July, 1,107 domains, is the largest.

Very few leave. 107 domains have lost the record since we began tracking it in March 2026, 1.19% of today's count, and 14 of those still carried it on another hostname when I checked on 11 October. Once a domain is verified there's rarely a reason to take the record down, so the low number says more about DNS habits than about loyalty.

"Amazon Business adds organisations by the million. Only a few thousand publish this record, and those are the ones where someone took ownership of how the whole company buys." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales signal: sell to this list as an installed base, not a wave. The record tells you who governs their Amazon purchasing today; it won't tell you who started last month.

Who the customers are

A wide middle, plus a large group of very small buyers. 32.1% of matched companies with a known headcount have ten or fewer employees, but 25.34% have 51 to 200 and 10.89% have 201 to 500, so 36.23% sit between 51 and 500. Only 312 employ more than 1,000, and 29 more than 10,000, even though Amazon says 97 of the Fortune 100 buy through Amazon Business. My reading: a giant can run Amazon Business without verifying the domain, while a 200-person company is exactly where Amazon's own pitch for Account Authority, scattered accounts and lost visibility, hits hardest.

Age points to established organisations: 42.54% (2,506 of 5,891) were founded before 2000 and 14.43% before 1960, while 14.19% date from the 2020s. The names fit. Micron, C.H. Robinson, QuikTrip, Huntington Ingalls Industries and TÜV SÜD sit near the top by LinkedIn following; further down are Culver's, Smoothie King, Davey Tree, Portland State University, Monroe County in New York and Special Olympics. I checked all 50 in DNS.

Sales signal: Prime Business is priced by buying users, from $179 a year for up to 5 users to $1,299 for up to 200, per Amazon's plans page. An organisation in the 51 to 500 band is the one choosing between those tiers, and it's where a seller of approval workflows or spend analytics has the clearest case.

Industries and countries

IT services lead at 9.08%, plus 1.89% under LinkedIn's older Information Technology & Services label. Software development (5.88%), construction (3.96%) and non-profits (3.78%) follow, then financial services (2.5%), hospitals and health care (2.46%) and religious institutions (1.94%). The top ten make up 35.85% of matched companies. I expected retail and hospitality higher. What the leaders share instead is many people placing small orders against one budget, whether that's laptops and cables or cleaning supplies for a church hall.

Geography is concentrated. The United States holds 4,464 of the 7,645 matched companies (58.39%), then Germany (807), the United Kingdom (612), Canada (462), Italy (265), France (229), Spain (154) and Japan (110). Australia has 21.

Sales signal: if you sell procurement or approval tools, start with IT services, construction and non-profits, the three largest groups outside software. Germany is the second market by a clear margin, 807 matched companies against the United Kingdom's 612, so a German-language campaign reaches more of this list than a UK one.

Rivals and switching

We don't publish a market share. Under CRM, where our records file it, the count would rank seventh behind Zoho and Salesforce, and the position tells you nothing about a buying channel. Its real rivals, such as Staples Business Advantage, Office Depot and Grainger, aren't measured the same way, so there's no competitor table either.

Switching is invisible for the same reason churn is low. An organisation that moves its supplies spend to another vendor has no reason to delete a TXT record, so the 107 exits since March could be lapsed accounts, retired domains or a tidy IT team.

"A verification record only comes down when someone cleans up DNS, so 107 exits in seven months tells you about housekeeping, not about whether buyers are leaving Amazon." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales signal: if you compete with Amazon Business, don't hunt for churn here. Use the list to find organisations that already centralised their buying, then pitch on category depth or contract pricing.

The stack around it

Percentages here are of the 9,011 live domains in our clean set. Microsoft 365 handles mail on 46.78% and Google Workspace on 22.96%, which matters because Account Authority keys everything to the work email. A row our table labels Apple iCloud Mail sits at 45.76%, but that's mostly Apple's own domain-verification record, so read it as a second business account verified on the same domain rather than as mail. Salesforce runs on 6.92% and Zoho on 4.95%. On the website side WordPress builds 43.24% and Elementor 12.67%, and Google Analytics is on 63.31%.

Sales signal: identity vendors should lead with Microsoft. Amazon says single sign-on covers the users routed through a verified domain, and on these domains the mail tenant is Microsoft 365 about twice as often as Google Workspace. Sellers of other company-managed spend accounts, such as Uber for Business, are likely to find the same governance-minded buyer here.

Key takeaways

1. 8,962 domains carry an Amazon Business verification record in October 2026, a floor on accounts, with 7,645 matched to a company.

2. That's fewer than one in a thousand of the 11 million organisations Amazon says it serves; the record marks the ones that govern purchasing centrally.

3. A mid-market base: 36.23% of matched companies with a known headcount have 51 to 500 staff, and 42.54% were founded before 2000.

4. The United States holds 58.39% of matched companies, and Germany (807) is a clear second.

5. No share and no competitor table, and only 107 exits, because DNS records rarely come down.

How to use this list

Filter to the 51 to 500 band in the United States, Germany and the United Kingdom, then split by industry. A first line that works for a spend-management tool: "Your team verified its domain in Amazon Business, so you've already put rules around one supplier; here's how other contractors your size apply the same rules to the rest of their spend."
