One code for the whole state

Wyoming is one of the rare states that never split its phone territory.

307 has covered every corner of it since 1947, from Cheyenne in the southeast to Gillette in the Powder River Basin. That makes the prefix unusually strong: anyone in the state sees it as familiar. For a business trying to earn trust across long distances, that recognition is worth a lot. A 307 caller ID says you are part of the state, not just selling into it.

Built for long drives and wide territory

Serving Wyoming often means covering a lot of highway between customers.

Cheyenne handles government and rail, Casper sits at the center of the state's energy business, and Gillette runs on coal and oil. A virtual 307 line lets one team cover all of it without offices in each town. Calls follow you to the mobile app, so a rep driving between job sites still picks up on the local number. There is no overlay on 307, so every number in the state shares the same familiar code.

When you cannot pick up, Allo does

Spotty coverage on the interstate should not cost you a lead.

When a call goes unanswered, Allo's AI receptionist takes it, 24/7, and records what the caller needs. Afterwards you get an AI summary instead of a voicemail to decode. The details sync to HubSpot, Salesforce or Pipedrive, and you can text the customer back from the same 307 number.

A 307 area code gets you picked up. Allo handles what happens next, on every call.
