About the 423 Area Code
The 423 area code stretches across Eastern Tennessee, with Chattanooga and Johnson City on either end and Kingsport rounding out the region. Chattanooga's chemical and manufacturing plants fax signed compliance records and shipping paperwork between facilities, where a confirmed transmission matters more than the speed of email. Clinics and courts in Johnson City and Kingsport handle the steady traffic of referrals, filings, and authorizations that local agencies still expect by fax. Send FAX Mail gives 423 businesses a number they can use straight from their inbox, with plans starting at $12.99/mo and number selection at no extra charge.

Yes. The 423 code covers all of Eastern Tennessee, so a number works equally well for an office in Kingsport, Johnson City, or Chattanooga. You pick the number from available inventory at no extra cost, and there is no requirement to be physically located in any particular city to use it.
When a manufacturer in the 423 region runs past its monthly page allowance, you move up to a higher plan rather than paying anything per page. Paid plans begin at $12.99/mo, choosing your 423 number is free, and there are no surprise setup charges. A 7-day free trial lets a heavy sender gauge the right tier before subscribing.
It is. Chemical and manufacturing plants in the Chattanooga area continue to fax signed records between facilities because the transmission leaves a tamper-evident trail that many auditors and partners require. Fax also sidesteps the spam filters that frequently block large email attachments.
No machine is needed. You attach your document to an email and send it to the recipient's fax number, and Send FAX Mail converts and transmits it. Incoming faxes to your 423 number arrive in your inbox the same way.
