The 667 code went live on March 24, 2012 to relieve pressure on 443, which was itself an overlay added in 1997 when 410 started running dry [1]. Because all three codes share the same geography, ten-digit dialing has been standard around here for decades, and nobody blinks at a 667 number the way they might in a smaller market.

Baltimore leans heavily on independent shops and mid-sized firms, with small and medium businesses producing roughly 70% of the goods and services in the city [2]. Zoom out to the state and there are more than 604,000 small businesses across Maryland, making up 99.5% of all employers [3]. Translation: you're in good company if you're running something modest but ambitious.

A local number matters here because Baltimore is a proud town. People pick up when the caller ID looks familiar, and they're quicker to hang up on anything that reads like an out-of-state marketing dial. A 667 line on your business cards and Google listing tells customers you're actually part of the neighborhood, not routing calls out of a call center in another state.

Features Baltimore Businesses Actually Use

A phone number is only the start. The features around it decide whether your team can actually keep up with the day.

Auto Attendant

Route callers to the right person without a receptionist. Handy when a Fells Point restaurant is fielding reservation calls while the manager is prepping for service.

Call Recording

Keep a record of quotes, service instructions, and customer requests. Useful for contractors in Towson who need to prove exactly what a client approved.

AI Transcription

Voicemails arrive as readable text, so you can skim them between meetings instead of holding the phone to your ear on the light rail.

Business SMS

Text customers from your 667 number. Great for salons in Federal Hill sending appointment reminders or auto shops in Dundalk pinging when a car is ready.

Mobile App

Take business calls on your cell without giving out your personal digits. Your work line rings wherever you are, from the Inner Harbor to the Eastern Shore.

Daily Billing

Tonet bills by the day instead of locking you into a monthly contract. If your team shrinks or grows, you only pay for what you actually used.
