There are many reasons why you may want to choose a local or toll-free number.

Local numbers are used to establish a presence in the area you are serving. Typically, service-based companies choose business phone numbers within, or near, the area code(s) they service.

Toll-free numbers provide some very important benefits to both your company and your customers. For starters, toll-free business phone numbers ensure that callers reaching out to your company from anywhere in the US and Canada are never paying long-distance charges. This can be a potential barrier for someone wanting to connect with your company, so it is good to remove that hesitation and keep the lines of communication open. Toll-free numbers are ideal for nationwide customer server support. Toll-free numbers also provide another great benefit to your company and can make your business appear larger or more established. They present a nationwide appearance and can be more appealing to customers across the country.
