The Hamptons and Montauk—two of the most notable vacation destinations in Suffolk County—fall under the 631 area code. These regions drive significant tourism and contribute substantially to the local economy during the summer months.

Managing Growth: The 934 Overlay Code
With continuous population growth and the proliferation of mobile devices, the original 631 numbers began running low. To avoid confusion from another area code split, the 934 overlay code was introduced in 2016. The overlay system ensures that 631 and 934 serve the same region, allowing residents and businesses to keep their existing numbers while accommodating new ones.
This transition to overlay codes also necessitated a shift to ten-digit dialing. While ten-digit dialing initially confused some residents, it has become the standard throughout the region.

The 314 area code is assigned to the eastern part of Missouri, primarily covering St. Louis and many of its inner-ring suburbs, such as Florissant, Chesterfield, and Maryland Heights. Introduced in 1947, it is one of the original area codes established under the North American Numbering Plan.
It operates in the Central Time Zone (CT), shifting between Central Standard Time (CST) and Central Daylight Time (CDT) during daylight saving periods. To manage number shortages in the region, an overlay area code, 557, was recently introduced, allowing new numbers to co-exist with 314 within the same geographic area.
Popularity and Challenges
While 631 Area Code USA remains a critical area code for Long Island, challenges include managing the demand for new numbers.
