Who we are

A quarter-century of UK communications, one customer at a time

Smart Numbers Ltd has been connecting UK businesses to their customers since 1998. We started with a simple idea, give small businesses the credibility of a proper landline without the kit, the contracts and the BT-era setup faff, and have been quietly improving on it for twenty-five years.

Today we run virtual landlines, VoIP, mobile-landline apps, 24/7 live answering, business websites and a stack of call-management features on tier-1 carrier infrastructure. Most of our customers stay with us for years. We think that's the metric that matters.
