Rehoboth is not in New Jersey it is in Delaware. All numbers in the 609 Area code starting with 399 or 398 are in the Ocean City,New Jersey area. I have added this site as a link on my web page http://www.info-ed.com/big-al/
Not true. There is a sub district of New Jersey known as Rehobath (note the spelling).
This is a biblical name meaning lands of plenty.
The area code is irrelevant as this district is preserved as a tourist attraction. It depicts the NJ Amish Community of the 18th Century and so no phones!
