About the 303 Area Code

The 303 area code covers the Denver metro and Boulder, including Lakewood. The local economy runs heavily on technology and aerospace, sectors that handle a steady load of compliance-sensitive paperwork. Courts, clinics, and energy firms across Denver and Boulder send signed documents by fax to meet legal and regulatory requirements. Tech companies in particular fax confidential records between offices rather than expose them to email interception. Send FAX Mail lets Colorado businesses fax from their existing inbox for far less than a traditional fax line costs.
