Numbers

To use MessageBird to connect with customers by placing and receiving voice calls, or sending and receiving SMS, MMS, or WhatsApp messages, you need to connect a number to your workspace.

Number types

Depending on the country you are buying a number for, we may offer more than one type of number that you can choose from. Each type has benefits and restrictions.

Some numbers can only be used for a single purpose, such as sending and receiving SMS messages, but others can be used for multiple purposes. Make sure that you know exactly how you want to use your number before you purchase one.

Mobile numbers

Generally speaking, these numbers feature the same services as being connected to mobile phone or cellular networks. In markets where mobile numbers are available, they are often the only type of number that can be used for multiple purposes, such as making voice calls, sending, and receiving messages. Mobile numbers are not available in every market, however, new destinations are being continually added.

Mobile numbers are best used for:

  • Conversational messaging

  • Multiple services under a single number

  • Advanced services such as Number Masking

Local numbers

Local numbers are numbers that start with a particular area code that has been assigned to a specific region, such as a city or a state. With the exception of North America, local numbers can not be used to send and/or receive SMS messages.

  • Building trust and credibility in a focused geographic region

  • Local branches of nationwide businesses

National numbers

Like local numbers, national numbers start with recognizable prefixes that make it easy for customers to recognize your brand, but because a single number can be used nationwide, national numbers help to integrate brand recognition at a country-wide level.

  • Building trust and credibility over a wide geographic region

  • Nationwide businesses

Toll-free numbers are free for the caller, which means that you can use them to provide a free point of contact for customers who call you. Instead, the cost of a call to a toll-free number is absorbed by the business.

Toll-free numbers are best used for:

  • Providing customers with a free contact number

  • Conversational messaging (North America only)

Shortcodes

Shortcodes are easy-to-remember numbers that are 4 to 6 digits long, and are used as a sender for two-way messaging. For North America, these provide the highest throughput for high-volume messaging campaigns.

Unlike many other number types, shortcodes do not contain local area codes, but they are only active on a national level and do not provide voice services Shortcodes are a national service and cannot be reached from foreign numbers.

Shortcode number capabilities vary from country to country.

  • High-volume marketing campaigns

  • Conversational messaging

  • Campaigns where an easy-to-remember number is beneficial, e.g. TV & Advertisement
