Dial Directions has expanded its service nationally. That means users can now theoretically get directions to and from any address or intersection in the US and some chain stores and selected other locations. (The company still needs to add a “points of interest” or other local database to round out the service.)

But far more interesting  is another feature — somewhat buried in the service — that was introduced last night: Meet Me. Dial Directions continues to be one of the more clever and creative mobile startups out there. Previously the company added the ability to get directions to events simply by saying the name of the event.

The new “invitations” service, Meet Me, allows anyone to record a greeting (e.g., “We’re all headed to the hotel for a drink”) and then send that to friends via text, together with directions to the location. What’s delivered is a text message with a prompt for a call, which plays back the greeting and provides directions to the intended location again via text. Messages can be forwarded to one or many an unlimited number of times.

There’s an interesting marketing or promotional opportunity here for bars, clubs and restaurants around offers or mobile coupons. But that’s not the intention of the service — at least right now.

Meet Me is a creative, but also very useful, feature of Dial Directions that will likely have uptake among younger users. And not to be underestimated is the value of the recorded message that allows people to customize Meet Me with a personalized greeting, jokes, etc.
