Almost as important as your company name, your phone number can be an identifier for those you are wanting to sell your products and services to. 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.

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.
