Two-way messaging requires either a short code or long number that enables your customers to reply to your SMS messages. According to recent research, as many as 64% of customers want to be able to engage with companies via two-way messaging and acquiring a long number (also known as a virtual mobile number) enables businesses to do just that.

Enabling a long text number for your business will allow you to receive messages and replies from your customers, starting meaningful two-way conversations with them using your dedicated phone number. So, what is a virtual mobile number all about, how does it work, and how can it benefit your business?

What is a long number?

Two-way long numbers, as the name implies, are long telephone numbers which can be up to 16 digits in length but are usually the length of a standard local phone number.

Long numbers are cheaper to use than short codes and will allow your business to receive replies from local and selected international destinations.

What are the benefits of using a long number for your business?

The greatest advantage is pretty obvious – you’re enabling your customers to respond to your SMS messages, starting a dialogue with them that would otherwise not have been possible. Long numbers are ideal for any SMS marketing campaign where it’s not important for you customers to remember your virtual mobile number and are the cornerstone of any great SMS campaign.

Here are just a few ways you can use Clickatell's global SMS long code service to grow your business:


Invite your customers (and potential customers) to enter a competition by replying to your promotional messages with their name and phone number. This is a great way to build up your customer database and identify new leads.

Banking alerts

Two-way messaging is the perfect way to send SMS alerts about important activity in a customer’s banking account but can also be used as a virtual number for verification purposes and transactional SMS messages.

Customer Relationship Management

Personalized customer interactions have become essential in building closer relationships with your client base. Integrating two-way messaging with your existing CRM program is a breeze and automating workflows using SMS saves significant costs while improving the overall customer experience.

Appointment reminders and confirmations

We all know that time is money. And, when a customer forgets an appointment or fails to cancel their bookings, substantial losses are suffered. Sending out automated reminders using a two-way long number, allows customers to conveniently confirm, cancel, or reschedule their upcoming appointments.

Get valuable customer feedback with SMS surveys

Surveys are an easy way for your customers to rate products or services by simply scoring them or replying with a YES/NO to your long number to indicate whether they would make use of a service/product again. Measuring your customer satisfaction levels and gaining valuable feedback has never been easier.

Polling campaigns

A two-way SMS long number is a very cost effective way to gather votes in a polling campaign allowing you to measure customer loyalty, collect data, or understand what your customers want most.

Allow customers to opt-out or request more information

Customers who don’t want to receive specific marketing messages can reply via your dedicated phone number to opt-out or, alternatively, respond with a request for more information without having to make a phone call.
