Salt Lake City Area Codes: A Comprehensive Guide

When you need to make a call to or from the Salt Lake City metropolitan area, knowing the correct area code is essential. Salt Lake City, the capital and most populous city of Utah, is served by several area codes due to its growth and the expansion of telecommunications. Understanding these codes ensures seamless communication for residents, businesses, and visitors alike.

This guide will break down the primary and overlay area codes serving Salt Lake City and its surrounding communities. We'll explore how these codes are assigned, what areas they cover, and provide practical tips for using them correctly. Whether you're setting up a new phone service, calling a friend, or conducting business, having this information readily available will prevent misdials and ensure your calls connect.

The Primary Area Code: 801

The original and most well-known area code for Salt Lake City and much of northern Utah is 801. This code has been in service for decades, covering a vast geographic region that includes the state capital and its immediate suburbs. For a long time, 801 was the only area code serving this populous region.

However, with the ever-increasing demand for phone numbers, especially with the proliferation of mobile devices and new businesses, the 801 area code began to run out of available numbers. This situation is common in many rapidly growing metropolitan areas across the United States. — NCAA Cross Country Championships 2025: Schedule & More

Historical Context of 801

Introduced in 1947 as part of the original North American Numbering Plan (NANP), the 801 area code initially covered the entire state of Utah. As the state's population grew, particularly along the Wasatch Front, the need for more numbering capacity became apparent. This led to the eventual splitting of the state, but 801 remained the core code for the Salt Lake City region for many years.

Overlay Area Code: 385

To address the exhaustion of available numbers within the 801 area code, the 385 area code was introduced as an overlay in 2015. An overlay means that the new area code is assigned to the same geographic region as the existing 801 area code. This allows for a much larger pool of available phone numbers without requiring existing customers to change their numbers.

How Overlays Work

When an overlay is implemented, both the original and the new area codes serve the same geographic territory. This means that a new phone number in the Salt Lake City area could be assigned either an 801 or a 385 prefix. Consequently, all calls made within this region, whether local or long-distance, must be dialed using the full 10-digit number (area code + 7-digit number), even if both numbers share the same area code.

This 10-digit dialing requirement is a key characteristic of overlay plans and is designed to help people adapt to the new numbering plan and avoid confusion. While it might seem like an extra step, it's crucial for ensuring calls are routed correctly.

Geographic Coverage of 385

The 385 area code covers the same geographic area as the 801 area code. This includes Salt Lake City, as well as surrounding cities and communities such as Sandy, West Valley City, Provo, Ogden, and many others along the Wasatch Front. Essentially, if a number is within the boundaries of the original 801 territory, it could now potentially have a 385 area code.

Key Differences and Considerations

While both 801 and 385 serve the same region, there are a few key differences and considerations for users:

• 10-Digit Dialing: As mentioned, with the 385 overlay, all calls within the 801/385 service area require 10-digit dialing. This applies to local calls as well as long-distance calls originating from or terminating within this region.
• Number Assignment: New phone numbers are assigned from either the 801 or 385 pool. Your existing number will not change, but new numbers might receive the newer prefix.
• No Geographic Separation: Unlike area codes that split a region, overlays do not denote different geographic locations within Salt Lake City. Both codes serve the entire metropolitan area.

What This Means for Residents and Businesses

For residents, the primary impact is the need to remember to dial the full 10-digit number for all calls within the service area. Businesses may need to update their marketing materials, websites, and phone systems to reflect the possibility of new numbers being issued with the 385 area code. It's also important to ensure any auto-dialing systems or contact lists are updated to accommodate the 10-digit format.

How to Identify the Correct Area Code

In most cases, when you look up a phone number or someone provides it to you, the area code will be explicitly stated. If you are unsure whether a number is in the Salt Lake City area, you can often infer it if the number is 10 digits long and you know the person or business is located there. Alternatively, you can use online area code lookup tools.

Using Online Resources

Numerous websites allow you to search for area codes based on city, state, or zip code. These tools are invaluable for verifying area codes, especially when dealing with unfamiliar numbers. For example, a quick search for "Salt Lake City area code" will confirm that both 801 and 385 are applicable.

Contacting Service Providers

If you are setting up a new phone line or need to confirm the area code for a specific location, contacting your local telephone service provider is the most reliable method. They can provide definitive information about number availability and assignment in your particular neighborhood within the Salt Lake City region.
