How verification works
We separate company identity from support-channel verification. A known official website does not automatically prove that a phone number, email address or chat URL is current. Each support channel is assessed against a company-owned source before the directory marks it verified.
Clear contact information at a glance
Pages use clear headings, support labels, official source URLs, verification dates, country context and independent-directory notices so visitors can quickly understand which contact methods are verified, which details are still being checked and where each published contact came from.
Read our verification methodology →Frequently Asked Questions
Quick answers about independence, verification and corrections.
Is AtoZ Contacts an official customer support provider?
No. AtoZ Contacts is an independent directory and does not provide support on behalf of listed companies.
Where does AtoZ Contacts get contact information?
We prioritize company-owned websites, official help centers, contact pages and corporate documentation. We record sources and verification dates before publishing support channels.
What happens if a company does not publish a phone number or email?
We state that a public contact method has not been verified rather than guessing or generating a number or email address.
Can a company request a correction?
Yes. Companies and users can submit a correction report with a source URL through our Report Update page.
Are company names and trademarks owned by AtoZ Contacts?
No. Company names, service marks and trademarks belong to their respective owners and are used for identification and directory reference.
