Clickatell offers the following dedicated two-way number options in the UK:
Dedicated long number – you choose a 10-digit long number from a list of available numbers.
Dedicated random short code – you’ll be assigned a random 5 digit number.
A short code is country-specific and you'll only be able to use it to send and receive messages in the UK.
Clickatell holds stock of long numbers and they are therefore available immediately after purchase.
Short codes require approval from all supported mobile carriers. We'll procure the short code and coordinate the approval process on your behalf. This process can take around 8-12 weeks.
Both long numbers and short codes usually have once-off application fees, as well as monthly subscription fees. You pay a per-message fee for all outgoing messages that you send from your number, but all incoming messages are free.

A UK long number is a flexible and cost-effective option and can be successfully applied for almost all two-way messaging use cases.
Short codes are generally used by larger brands with significant two-way messaging volume requirements. A short code is short and therefore very recognizable which makes it a good option if you want potential customers to reach out to you first. Advertise your short code to ensure that your customers know how to reach you.

Here is a short checklist of general best practices for SMS campaigns which we recommend you keep in mind if you are sending out marketing messages.
It is recommended that you use a dedicated two-way number in the UK for your brand. A dedicated long number or short code provides better control and visibility for your brand as well as a better customer experience for your customer. Sharing a number with other businesses means that your customers will have to correctly type a specific keyword pre-registered by your business in the body of the SMS for the message to be routed to you correctly. By using a dedicated number, your customers will start to recognize and trust messages sent from your number as the messages will likely all display in the same thread.

During the festive season, some network carriers in the United States implement a freeze period on short code processing. The freeze period usually ranges from mid-December to mid-January. It is therefore recommended that short code provisioning and amendments/migrations are done before the freeze period to avoid delays.
