Pronounced "Six Thirty", the 630 refers to a new popular dance in the Caribbean, in particular Barbados. Women bend over from a standing position til their upper and lower body are oriented like the hands of a clock at 6:30 (30 minutes past six o'clock). They then procede to wine and gyrate their hips in a seductive manner, almost replicating the act of sex.

The 630 is the former home to most of Chicago's celebrities, including The Hush Sound, some of Wilco, John and Jim Belushi, Plain White T's, Will & Grace's Sean Hayes, and many local broadcast personalities

The 331 overlay area code Takes place in October, 2007, and will mix in with the 630.

Someone from the 630 is different to the eye than the other Chicago area codes: they are often dressed better, as the 630 has the highest per-capita income in the Chicago region. There is also a high percentage of teenagers in the 630 who consider themselves to be "punk", "emo", "indie" or "goth". 630's are also very strong Chicagoan wannabe's. They also consider themselves to be an extended part of the city, and tend to tell people they are from Chicago, especially in towns close to the city such as Villa Park, Lombard, Elmhurst, Addison and Oak Brook.

Downtime in the 630 usually includes joyriding, various school activities, shows/concerts, the wonderful Chicago-style food, excellent shopping, and taking the train. Most transportation is via the Metra train system, usually east into Chicago. Most of 630 east of Wheaton is layed out on a grid similar to the city of Chicago.
- "Dude, look at that sexy 630 other there!"
- "No way, man. That chick is totally an 847, she looks too suburban to be a 630."

"I was mauled by emos in 630 today."

"There's a show in 630 today, with some cool local bands!"

"There is no way a 630 would be caught dead in 815, they're too far from the city."
