Choosing the best phone number for your contact center

Business communication isn’t just about being reachable. It’s about building trust, maintaining a professional image, and ensuring customers can connect with you effortlessly. While a phone number may seem like a small detail, the type you choose can influence answer rates, customer satisfaction, and even brand perception.

In this guide, we'll walk you through the different types of phone numbers, their specific benefits, and practical steps for implementing them—helping you optimize your contact center for both exceptional customer experiences and operational efficiency.

Choosing the right phone number for your contact center

Your phone number choice impacts how customers perceive and interact with your business. Understanding the benefits of local and toll-free numbers can help you make the right decision.

Local numbers enhance accessibility

A local phone number is a telephone number that is assigned to a specific geographic area, typically within a city or region. It has an area code that corresponds to a particular location, making it recognizable to local callers. Local phone numbers create a sense of familiarity and accessibility.

One of the most compelling benefits of local phone numbers is their positive impact on answer rates. Consumers have become hesitant to answer calls from unfamiliar or international numbers due to the prevalence of robocalls and spam. Research shows that customers are 4 times more likely to answer calls from recognizable area codes.

When a consumer sees an incoming call, the split-second recognition of their own area code triggers what psychologists call the "mere exposure effect", our natural tendency to prefer things we recognize over those we don't. This creates a powerful sense of safety that counteracts defensive screening behaviors consumers have developed.

For contact centers, these higher answer rates translate directly to improved agent productivity and higher connection rates for outbound campaigns.

Toll-free numbers remove cost of calling for customers

Toll-free numbers remove barriers between businesses and their customers by eliminating call charges for the customer. Recognizable by their distinct three-digit prefixes (800, 888, 877, etc.), these numbers signal professionalism and accessibility, making customers more likely to reach out.

One of the biggest advantages of toll-free numbers is their ability to encourage customer engagement. Customers are more likely to call a business when they know the call won’t cost them anything. Beyond engagement, toll-free numbers also enhance brand credibility. A toll-free number reinforces the perception of an established, customer-focused business. It communicates that support is readily available, no matter where a customer is located.

For contact centers, this translates into better customer satisfaction thanks to free and easy access to support, increasing trust and loyalty. By integrating toll-free numbers into their communication strategy, contact centers can break down cost-related barriers, boost engagement, and strengthen their reputation with customers.

Should your business use a local or toll-free number?

The right choice of number depends on your contact center’s reach and customer expectations. To find the perfect number for your business, start by asking these key questions:

• Are we serving a specific region or a national/international audience? Local numbers build trust in specific markets, while toll-free numbers make support more accessible across the US and Canada.
• Are we prioritizing inbound or outbound calls? Toll-free numbers make it easier for customers to reach you, while local numbers improve answer rates for outbound calls.
• Are we running outbound campaigns for market search or lead generation? Local numbers help increase connection rates, reducing the chances of being flagged as spam.
  

In general, local numbers are ideal for contact centers focused on regional markets. These numbers increase answer rates and make businesses feel more approachable. Toll-free numbers are best for contact centers handling national or international support. Many contact centers use a mix of both to balance local trust and nationwide accessibility.
