No App Like It

I use it all the time and it does everything I need for area codes and prefixes and for Zip Codes. A while back I got a message on my phone that the App would not work on the next release of iOS. Concerned, I went looking for a replacement and discovered there really isn’t one that does all this app does — really nothing even close! Fortunately the developer updated the program and in the process made it even better. If they hadn’t I don’t know how I would have met the need. For me it is one of the most important capabilities of my phone.

A very useful app!!!

I haven’t used all the functions of the app yet. I have had it for a long time and use it several times a week. My main usage is zip +4. I use this for both business & personal use. It is fast, easy, and accurate. I highly recommend this app for useful information on addressing. I don’t know what I’d do without it.

No longer skeptical.

Very very skeptical that this freebie could do the required job. Tested all search categories for both zip codes and area codes, and was delighted with the results. I'm no longer skeptical, and already know this will be an invaluable tool for me. Deserves the full five star rating.
Thanx to the developers.
