What is the 557 area code?
Area code 557 is the newest identifier for Missouri’s Gateway City and its surrounding urban core. Connecting businesses to a major metropolitan economy of over 2.8 million residents, it serves as the modern overlay for the historic 314 area. It links companies to a landscape dominated by aerospace (Boeing), biotechnology research, and Fortune 500 headquarters. For any enterprise, a 557 number provides a localized St. Louis identity in a city that values geographic roots and heritage. It allows companies to tap into a diverse, resilient market while signaling a modern, tech-ready presence, providing the local trust needed to thrive in Missouri’s primary commercial and cultural corridor.
Facts about this Area Code:

Why your business needs a 557 number
Build a local presence in Missouri’s gateway and corporate heartland.
Establish a Local Presence
A 557 number signals you are part of the local community and the St. Louis landscape, providing the identity needed to compete with established local firms. By adopting this prefix, you show residents in Downtown, Clayton, and Chesterfield that you are a committed stakeholder in the region. This local rooting is essential for winning trust and building the lasting professional relationships required in this high-growth and technologically advanced market.
Boost Trust & Answer Rates
Using a local area code fosters trust and significantly increases your connection rates. Residents and local businesses in the St. Louis area are naturally more inclined to answer calls from recognized local numbers rather than unknown out-of-state prefixes or toll-free lines. This immediate recognition reduces skepticism, allowing your team to have more meaningful conversations, improve customer service, and convert leads more effectively within the region without being dismissed by busy professionals.
Look Professional
As the newest area code for the Gateway City, the 557 prefix projects an image of growth and modern connectivity. It ensures your brand is perceived as a serious player, standing alongside major regional banks, global aerospace giants, and world-class healthcare systems. Whether you are a small startup or an expanding enterprise, this code elevates your professional profile and commands respect in every outbound communication across the St. Louis metropolitan area.
