Data sources

Last updated: October 13, 2026

The business details LeadMarina returns — names, addresses, websites, phone numbers, email addresses and owners’ names — come from public business listings, the businesses’ own websites, the open datasets and public records below, and the providers that verify phone numbers and email addresses. We do not access private or password-protected information.

Open datasets

Overture Maps — places — Overture Maps Foundation. Email addresses a place lists, matched to a lead by its phone or website. Licence: CDLA Permissive 2.0 (Meta, Microsoft, PinMeTo, Krick, RenderSEO, DAC, BrightQuery); Apache 2.0 (Foursquare); CC0 1.0 (AllThePlaces).
Foursquare Open Source Places — Foursquare Labs, Inc.. Email addresses a place lists, matched to a lead by its phone or website. Licence: Apache License 2.0.

We changed both datasets: we keep places in the United States and Canada, normalise their phone numbers and websites, and use an email address only when the phone number or website it is listed under belongs to one business, never one that many places share. The licences’ texts and Foursquare’s notice are reproduced below.

Owners’ names

An owner’s name comes from the business’s own website or from a web search for the business — both read by an AI model — or from the public records below.

When a business’s own website names no owner, a lead may name the person the website names as running part of the business — a general manager or a practice’s doctor, for example — with the role the website gives them, also read by an AI model.

Public records

Owners’ and officers’ names come from records these agencies publish. We use a name only when the record names a single person for the business, and never someone named on many unrelated companies, such as a professional registered agent or an accountant.

National Plan and Provider Enumeration System (NPPES) — U.S. Centers for Medicare & Medicaid Services. Healthcare practices' authorised officials and practitioners.
Motor Carrier Census — U.S. Federal Motor Carrier Safety Administration. Trucking companies' officers and email addresses.
Contractor licences and principals — Washington State Department of Labor & Industries. Contractors' licensed principals.
Business entities — Colorado Secretary of State. Companies' registered agents — also under the names the companies trade as — when the agent is a person named for no more than five companies.
Trade names — Colorado Secretary of State. The person who registered the name a business trades under.
Active corporations — New York Department of State. Corporations' chief executive officers.
Corporations and fictitious names — Florida Department of State, Division of Corporations. Companies' officers and trading names' registrants.
Franchise tax public information reports — Texas Comptroller of Public Accounts. Companies' officers, directors, managers and members.
Registered businesses — Pennsylvania Department of State. Companies' officers.
Contractor licences — California Contractors State License Board. Licensed contractors' sole owners, presidents, members, partners and managers.
Active businesses — Oregon Secretary of State. Businesses' registered agents, when the agent is a person named for no more than five businesses.
Business licences and owners — City of Chicago. Licensed businesses' owners: sole proprietors, presidents, managing members, partners and managers.
Form 5500-SF filings — U.S. Department of Labor, Employee Benefits Security Administration. Who signed a small business's retirement plan filing, when their family name is in the business's name.

Removing your information

To have your email address, phone number or name removed from the leads we return, email [email protected] from the address you want removed — or tell us the phone number, or your name and your business’s website or phone number. Within a day of confirming the request, we remove an email address or phone number from every lead we hold and from all the website text we stored, and a name as the owner of your business and from the website text we stored for it. After that, no lead we return lists that address or number, or names you as its owner. A business’s own name and web address stay as they are in its listing, and we cannot recall copies our customers have already downloaded or exported.

      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain

      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including

      the copyright owner. For the purposes of this definition, "submitted"

      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
