Chicago has one code for the Loop and one for the rest of the city, and customers notice the difference. Choose your Chicago number and Allo adds an AI receptionist, call recording and AI summaries to every call.
In the city itself, 312 and its overlay 872 cover the Loop and the immediate downtown core, while 773 covers all of Chicago outside the Loop.
Areas are approximate. Codes that overlay each other share the same area.

Chicagoans like to deal with people who know the city.
A Chicago number fits whether you are pitching trading firms in the Loop, restaurants in West Loop or homeowners in Lincoln Park. Logistics, finance, healthcare, manufacturing and professional services all keep the phones busy here. Showing up with a local code makes the first call feel like a call from across town.
The split between 312 and 773 follows the Loop.
312 is the classic downtown code, and 872 overlays the same downtown core, so new downtown numbers often come from 872. 773 covers every Chicago neighborhood outside the Loop, from Wicker Park to Hyde Park. If you sell to offices downtown, lean toward 312 or 872; if your customers are spread across the neighborhoods, 773 feels closer to them.
Your Chicago number is the front door, and Allo runs everything behind it.
An AI receptionist answers when the team is out, so no caller hits an empty line. Calls follow your routing rules, every conversation can be recorded, and AI summaries land in HubSpot, Salesforce or Pipedrive. You can text from the same number and use it on desktop or mobile.
The number gets you picked up. Allo handles everything after that.
A local area code your prospects recognize means more calls get answered and more callbacks come through.
The AI receptionist picks up when your team can't, answers questions, qualifies the lead and books the meeting.
Ring your team together or one after another, with business texting built in, so no call slips through.
Recording, summary and next steps land in your CRM automatically, so follow-up is done before you hang up.
