Free Area Code Lookup

Quick lookup of Area Codes


Once I got a call from a client after hours the previous day, so we called them right at 9:00 a.m. Eastern the next day. The problem was that they lived in California and had a home office, so I woke them up at 6:00 in the morning!

That may have been the inspiriation that caused me to create the Area Code / Time Zone Master List. I keep a copy by my desk and tens of thousands have done the same. There's other great area code resources on this page. Check it out!
