Thirteen jurisdictions on one side, silence on the other
RocketReach collects sales tax by customer address in thirteen jurisdictions — Arizona, Colorado, Connecticut, Kentucky, Massachusetts, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Texas, Washington and the District of Columbia — and has separately charged VAT since November 2024 in Australia, Canada, India, Switzerland, the United Kingdom and the European Union. ZoomInfo’s license terms instead make the customer liable for sales and use tax outright, require the customer to indemnify ZoomInfo, and route any exemption through a certificate emailed to ar@zoominfo.com — with no tax page, no state named, and no nexus statement anywhere. Both companies collect somewhere in the United States; only one says where.
One vendor’s own numbers do not agree with each other
RocketReach’s help article states “over sixty million companies,” while its sales solutions page states “over thirty-five million companies,” both paired with the same claim of “over seven hundred million professionals” and neither dated. RocketReach publishes both figures and reconciles neither. ZoomInfo, by contrast, states a single set of numbers on its own page — over five hundred million professional profiles, over three hundred million verified business emails, over one hundred thirty-five million direct dial numbers and over one hundred twenty-two million company records — though it attaches no publication date to any of them either.
A credit that rolls over, or does not
RocketReach charges one credit per verified profile and never twice, metered across two separate meters for lookups and exports, but its own pages disagree on what happens to unused credits: one states “rollovers with active plans,” another states “no rollovers.” RocketReach publishes both rules and reconciles neither, and elsewhere adds that credits expire after twelve months or at cancellation regardless. ZoomInfo’s bulk data credit works differently in kind: it is spent once, on a record’s first enrichment, after which that record goes “Under Management” for twelve months and can be re-enriched at no further cost.
Two certification lists from the same company
ZoomInfo publishes two vendor pages with two different certification lists: ISO 27001, ISO 27701 and SOC 2 Type II appear on both, while TRUSTe and ISO 27017 appear on only one of them. ZoomInfo publishes both lists and reconciles neither. RocketReach names a shorter, single list for itself — SOC 2 Type II and ISO 27001, obtained in 2024 — and states nothing about its host’s own certifications on either page.
A registry both vendors half-fill
ZoomInfo registers as a data broker in Texas alone, not in California or Vermont, while naming fifteen state privacy laws with four more announced and admitting outright that it sells personal data. RocketReach names only Texas as well for the data broker registry, but separately documents a California removal process handling three thousand three hundred sixty-seven requests in 2025 in under a day; neither vendor’s pages mention Virginia, Colorado, Connecticut, Utah, Oregon or Montana by name, a silence about those states rather than a claim of exemption from them.
A refund that exists, and a refund that does not
RocketReach’s subscriber agreement states a purchase is “non-refundable... once it has started,” while its help pages separately describe a seven-day window for a mistaken annual subscription, refunding “the difference in price.” RocketReach publishes both positions and reconciles neither. ZoomInfo’s license takes a different, single position: material obtained during the contract term stays usable after it ends, but remains bound by the agreement, so resale or transfer to a third party is never permitted.
