Address and Phone Books

These are some of the best resources for finding the address and phone number of a company. They are included here for their convenience, comprehensiveness, and/or ease of use. Additional resources on the company profiles page can also be used if they are more convenient.

If you are looking for an organization which is not a company, check our related directories page.

If you are having trouble finding a company:

• Check alternate spellings.
• Check regional directories if it is a local company.
• Check to see if a specialized industry directory is available which may be more comprehensive.
• Consider that it may be a "non-company" involved in business activities. Check related directories.
• Search for an internet site for the company. It may be too new to yet appear in these resources, or may be a home-based business which often won't appear in the directories.
