What Area Code Is 573

Have you ever received a phone call from an unfamiliar number and wondered where it originated? Area codes are more than just three digits; they're geographical fingerprints that can tell you a lot about where someone is calling from. Knowing the area code can help you decide whether to answer the call, recognize a local business, or even identify a potential scam. Furthermore, with the increasing mobility of people and businesses, area codes can sometimes be misleading, making it essential to stay informed about their current geographical assignments. Understanding area codes like 573 is crucial for various reasons. It helps in identifying the location of incoming calls, verifying the legitimacy of businesses, and even providing a general sense of the caller's origin. In a world increasingly reliant on communication, knowing the geographical location associated with an area code empowers you to make informed decisions about the calls you receive and the businesses you interact with.

What are the key things to know about area code 573?

What locations are covered by area code 573?

Area code 573 covers a large portion of eastern and southeastern Missouri, encompassing the state's central region and extending towards the bootheel. This includes major cities like Columbia, Jefferson City (the state capital), Cape Girardeau, and Rolla, along with numerous smaller towns and rural communities.

The 573 area code serves a primarily rural and suburban area of Missouri. It stretches from the Mississippi River westward, covering a significant portion of the state's landmass. Due to the area's size, it's important to note that simply knowing a phone number starts with 573 does not pinpoint a precise location without further information, as it could be associated with a resident or business many miles away. The area code was created in 1996 when it was split from area code 314, which primarily serves the St. Louis metropolitan area. This division was necessary to accommodate the growing demand for telephone numbers in the region. Since its inception, area code 573 has provided reliable telecommunications services to the diverse communities it encompasses.

Is area code 573 only in Missouri?

Yes, area code 573 is exclusively located within the state of Missouri. It serves the eastern and southeastern portions of the state, excluding the immediate St. Louis metropolitan area.

Area code 573 encompasses a large geographic region of Missouri, covering cities like Columbia, Jefferson City (the state capital), Cape Girardeau, and Rolla. It's important to note that while area code 314 primarily serves St. Louis City and St. Louis County, and area code 636 covers much of the surrounding suburban St. Louis area, 573 picks up much of the rest of eastern and southeastern Missouri. This includes a mix of urban centers, smaller towns, and rural communities. The introduction of area code 573 occurred in 1996 as a split from the original area code 314. This split was necessary due to the growing demand for telephone numbers driven by factors such as population growth and the increasing use of cellular phones and other communication devices. By geographically dividing the service area, the phone companies could provide more telephone numbers and handle the volume.

When was area code 573 established?

Area code 573 was established on January 7, 1996, as a split from area code 314.

Prior to 1996, the entire eastern and southeastern portion of Missouri, including the St. Louis metropolitan area, was served by area code 314. As the population and the demand for telephone numbers grew, particularly with the rise of cell phones and fax machines, it became necessary to create a new area code to avoid exhausting the available number pool. The creation of area code 573 allowed for continued growth and service in the region without the need for more drastic measures like overlay codes in the immediate future.

The implementation of area code 573 involved a permissive dialing period, during which both 314 and 573 area codes could be used to reach numbers in either region. This allowed residents and businesses time to adjust to the new dialing patterns. After the permissive period ended, dialing the correct area code became mandatory for all calls.

How do I dial a number in area code 573?

To dial a phone number in the 573 area code, you will typically dial 1 + 573 + the 7-digit phone number if you are calling from outside the 573 area code. If you are calling from within the 573 area code, you may need to dial 1 + the 7-digit phone number or just the 7-digit phone number, depending on your local dialing rules.

The 573 area code covers a large portion of central and southeastern Missouri. This includes cities such as Columbia, Jefferson City (the state capital), Rolla, Cape Girardeau, and many smaller towns and rural areas in between. Understanding the coverage area can help clarify when you need to use the area code.

Due to the prevalence of mobile phones and the increasing demand for phone numbers, some areas have implemented mandatory 10-digit dialing (area code + 7-digit number) or even 11-digit dialing (1 + area code + 7-digit number) for all calls, even local ones. Check with your local phone service provider to confirm the specific dialing requirements in your location to ensure your calls connect successfully.

Are there any other area codes that overlap 573?

No, area code 573 does not currently have any overlay area codes. This means that within the geographic region covered by 573, you do not need to dial the area code when calling another number within the same area code.

Area codes are sometimes overlaid when the original area code is running out of available phone numbers. An overlay introduces a new area code to the same geographic region, requiring ten-digit dialing (area code + seven-digit number) for all calls, even local ones. Without an overlay, seven-digit dialing is typically sufficient for local calls. Area code 573 serves a large portion of eastern and southern Missouri. Given population growth and increasing demand for phone numbers, it is possible that an overlay could be implemented in the future if the supply of available numbers dwindles. However, as of now, no overlay exists. Therefore, seven-digit dialing is generally sufficient when calling within the 573 area code.

What's the population size within area code 573?

Estimating the precise population within area code 573 is challenging, as area codes don't perfectly align with governmental boundaries like cities, counties, or census tracts. However, based on the areas primarily covered by the 573 area code, which largely includes Southeast and Central Missouri, the population is estimated to be around 800,000 to 900,000 people.

The 573 area code encompasses a diverse mix of urban and rural communities. Major cities within the 573 area code include Columbia, Jefferson City, Cape Girardeau, and Rolla. Because area codes are assigned based on telephone service needs and not geographical divisions, population estimates are extrapolated by analyzing population data from the cities and counties that intersect with the 573 area. This makes obtaining an exact number difficult, but provides a reasonable approximation.

It's also important to note that population figures are dynamic and change over time due to births, deaths, and migration patterns. The estimated population range mentioned above is based on the latest available census data and demographic projections. For highly precise population numbers related to specific geographical areas, one should consult official data from the United States Census Bureau and relevant state or local government agencies.

Is area code 573 running out of numbers?

While area code 573 is not currently projected to run out of numbers in the immediate future, number exhaustion is a factor that telecommunications planners constantly monitor and address. Numbering resources are managed to ensure continued availability for new phone subscribers and services in the region.

Area code 573 serves a large geographic area in Missouri, encompassing the eastern and southeastern parts of the state outside of the St. Louis metropolitan area. The North American Numbering Plan Administrator (NANPA) is responsible for overseeing and allocating numbering resources across the US and its territories. They monitor utilization rates and forecast future demand to determine when a new area code might be needed. Conservation methods, such as number pooling (allowing carriers to share blocks of numbers), help to extend the life of existing area codes. Although there are no immediate plans for relief (such as an area code overlay or split) for 573, it's important to note that telephone number resources are finite. Population growth, increased use of mobile devices, and the proliferation of internet-connected devices (the Internet of Things) all contribute to the demand for new numbers. NANPA regularly assesses the need for new area codes across the country based on these trends. Changes to area codes are announced well in advance to minimize disruption for customers.
