Hey, SWGB!! I thought everyone was doing a pretty good job answering a complicated question. I was out of town for a few days. But, since you asked, I'll chime in a little bit.

Russ and Kimberly. Do you really live in Seagrove? Exactly where on 30A do you live? Do you need to know this for any particular reason? Many today that think they live in Seagrove, would never be considered as doing so by some.
South Walton is a good overall description for our unincorporated area south of the bay in Walton County. SoWal works for a lot of people.
Walton County is one of the oldest counties in Florida, founded December 29, 1824. Many community names have come and gone. We only have three incorporated cities in the entire county, all north of the bay -- Freeport, DeFuniak Springs and Paxton. In my opinion, until South Walton becomes incorporated, we'll probably have community name issues. We might all decide to just use South Walton one day. We do have a high school, library, government center and a hospital that we didn't have just 10 years ago.
Seagrove Beach used to be Russ Hammock. Miramar was Yellow Bluff and Blue Mountain was Double Yellow Bluff. The early plat for Eastern Lake Estates has Pt. Washington on it. A 1931 Walton County map shows the Eastern Lake area as Miramar. We could go on and on.
For example, take Ft. Walton Beach's name transformation. It is named for Walton County's namesake, George Walton, Jr. Earlier maps have it notated as Anderson. Then it became Camp Walton. After that, Ft. Walton. In 1953 "Beach" was added to make it more marketable. Incorporated cities have the ability to change their name.
Santa Rosa Island is the historic name since early Spanish Florida days. It wasn't until Okaloosa County was made in 1915, half out of Walton County and half out of Santa Rosa County, that some there took to calling part of Santa Rosa Island, Okaloosa Island.
Santa Rosa Beach was just made up, too. Earlier Santa Rosa was Hog Town. The Choctawhatchee Bay was known for many many years on Spanish maps as Santa Rosa Bay. It wasn't until the British temporarily had West Florida during the American Revolution that the name changed.
We've discussed this on other threads. Perhaps some clarity will come with the 2010 census. Millions of dollars will be on the line for Walton County to correctly count its citizens and where they are. Hopefully, we can get GPS, Google, etc. to properly identify our locations one day.
Right now we are located between two regional post offices, according to Northlake on another post. Pensacola is 325 and Panama City is 324. If your zipcode is giving you problems, the solution won't come easy -- you are dealing with the Federal Government and the Post Office.

But, there isn't a law that says we can't and won't get new and better zipcodes. Best just work as best as you can with the Post Office for now if you are having mail delivery issues. They may just tell you to use whatever name you want to as long as you have the zip correct.
Name changes and fluctuations are common throughout history and in many places. Just because someone puts up a sign or names a Condo something, doesn't make it so. Its fluid. Community and time should have some bearing, imho.
Where do you want to be?
