Clickatell will attempt to deliver messages with your Sender ID, where possible. Please note, however, that we cannot guarantee that messages will be delivered using your specified alphanumeric Sender ID as it may be changed by our carrier networks, with or without notice, resulting in a different Sender ID being used. This value-added feature is offered on a best-effort basis – delivering your messages is our first priority. Read more about how Sender IDs work here.

A good alternative to Sender ID is to use a short code, which will provide a numeric Sender ID that your customers can get to know and associate with your company or brand.

Get in touch with our Sales team if you have questions about Sender ID.

From time to time, carriers will request an active copy of the Common Short Code Administration (CSCA) lease. This is to prove that we have a working relationship with you so that we are allowed to send messages on your behalf via your code. Should a carrier request your lease and we do not have it on file, there is a good chance that there may be a disruption in service.

• Angola

Clickatell has recognized a shift in the business-to-customer messaging environment, with more message-sending regulations introduced in many territories and countries. Non-compliance with these restrictions may lead to non-delivery of messages, which is why you need to familiarize yourself with the terms applicable to the relevant territories.

Regulations typically pertain to the following:

• Time of day that messages may be delivered

• Content of the messages

• Format of the Sender ID (from address) that may be used/displayed. Carriers in certain countries will block SMS messages that are sent from phone number formats that they do not recognize or support. To help ensure that your messages are delivered, the from address of a message may be replaced with a format that will be accepted by the carrier of the mobile device.

Read more about Sender ID restrictions and review specific regulations for each country we support message sending to.

For further information, assistance, or help, contact our support team. We’re experienced in delivering messages to each of these countries and will assist you in making a success of your messaging program.

What two-way messaging options are available?

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.

What are the expected provisioning times?

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.

What are the costs involved?

Only applicable to our self-serve clients. If you are on one of our paid packages, please reach out to your account manager or our support team.

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.

To see estimated pricing, go to the Clickatell pricing estimator, choose the United Kingdom, select your two-way messaging option of choice, and indicate your expected outbound message volumes.

Which two-way messaging option is best for my business?

Long numbers

A UK long number is a flexible and cost-effective option and can be successfully applied for almost all two-way messaging use cases.

• Appointment reminders – Reduce the number of “no-shows” by sending appointment reminders for medical appointments, vehicle servicing, real estate agents, recruitment agencies, or any other service-related business. For example Your dental appointment with Dr. Smith is scheduled for 9 January, 14:00 pm. Reply cancel or confirm.

• Customer alerts and notifications - Improve customer experience with timely and instant notifications. For example Hi Adele. Your flight SA34009 will be delayed for 2 hours. We apologize for any inconvenience. Please have a free coffee on us at Coffee Café with coupon 38274.

• Opt-out compliance – Use a long number as a way for recipients to opt-out of your list with a simple keyword to comply with ICO regulations.

• Booking and payment confirmations – Instant confirmation on purchase or booking set your customer’s mind at ease. For example: Thank you for your purchase at ABC.com. We've received your payment for order #82492. To track your order, reply with your order no.

Short codes

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.

• Competitions – text-to-win competitions are a great way to get exposure for your brand. For example: "Text ‘XX BRAND NAME’ plus your name+email address to 60777 to win a trip for four to Disneyland. See yourbrand.com for terms."

• Lead generation – SMS is a very cost-effective way to make it really easy for potential customers to show interest. For example: "SMS your name to 38264 and we’ll call you back with a quote."

• Opt-in for marketing lists – For example: "SMS your name to 82625 to receive our monthly discount coupons."

Best practices

Here is a short checklist of general best practices for SMS campaigns to 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.

It is also recommended to whitelist URLs that will be included in the message from the brand to customers to ensure successful delivery. Please reach out to your Account Manager or contact our Support team to learn more.

Regulatory information

• In the UK, the Privacy and Electronic Communications Regulations (PECR), released by the Information Commissioner’s Office (ICO), governs text marketing laws based on the Data Protection Act.

• The General Data Protection Regulation (GDPR) is a regulation by the European Commission with the intention of making data protection stronger for people and organizations in the European Union. Clickatell is dedicated to maintaining GDPR compliance.

• Lastly, make sure that your use of two-way numbers is in line with our terms and conditions.

• How to apply for a long number

• How to apply for a short code

During the festive season, some network carriers in the United Kingdom 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.

What two-way options are available?

Clickatell offers dedicated short codes in South Africa.

A South African short code is five digits long and has four accompanying long numbers, one for each local network. When you send a message using a short code as a source address, the receiving handset will see the relevant long number associated with that short code as the sender ID. For example: when you send a message to a Vodacom handset from your short code, the recipient will receive that message from the Vodacom long number for that short code. The long numbers will be unique to each short code.

In South Africa, a short code is country-specific and can only be used to send and receive messages.

What are the expected provisioning times for short codes?

Clickatell will procure the short code and coordinate the approval process with all supported mobile operators on your behalf. The entire process can take up to seven days.

On approval, your dedicated short code is randomly assigned from a pool of available numbers.

What are all the costs involved with a short code?

A dedicated SA short code has a once-off application fee as well as a monthly subscription fee.

All incoming messages to your short code are free, but you pay for outgoing messages.

To get a complete pricing estimate, go to the Clickatell pricing estimator, choose South Africa, select Two-way messaging > short code, and indicate your expected outbound message volumes. Please bear in mind that all outgoing message pricing is estimated as costs are calculated at the time of sending.

Best practices

• Here is a short checklist of general best practices for SMS campaigns that we recommend to keep in mind if you are sending out SMS campaigns.

• In addition to the general best practices, it is best practice in South Africa to offer the recipient a free method to opt-out of your list.

• It is recommended that you identify your company name in the body of your message, since it is not possible to receive a message from a short code in South Africa but only from the associated long numbers as per network regulations.

• For insurance-driven marketing programs, a reverse billed short code is recommended by the Insurance Ombudsman due to the fact that the mobile subscriber needs to have a free opt-out message. Please contact our sales team for more information on a reverse billed short codes.

• The Mobile Marketing Association provides some useful trends and best practices for marketing to consumers via mobile.

Regulatory information

The Independent Communications Authority of South Africa (ICASA) is the official regulator of the South African communications, broadcasting, and postal services sectors.

We’ve created a quick overview of SMS regulations and restrictions in South Africa that may be applicable to your short code.

It is your responsibility to consult with your legal team and to ensure that your opt-in and opt-out processes, message content, and all other aspects of your message sending within South Africa comply with the applicable legislation as well as the Clickatell terms and conditions to avoid your number being blocked, or substantial fines imposed.

Clickatell is also a member of the Wireless Application Service Providers’ Association (WASPA) and we are bound by their code of conduct.

What are the two-way options are available?

Clickatell offers dedicated short codes and long numbers for the USA.
Types of dedicated short codes available:

• Random short code – you’ll be assigned a random 5 or 6 digit number

• Vanity short code – request your own custom 5 or 6 digit number

Which type of two-way number is best for your business?

For more information, read our FAQ about the difference between short codes and long numbers.

Below is additional information to decide which two-way option is best for your business:

Short codes can either be random numbers or a hand-picked recognizable 5-6 digit number. Large brands usually opt for a dedicated short code to use on their marketing material and as a recognizable from address when sending high volume marketing or promotional messages.

Short codes are best for:

• High volume Application-to-Person messaging with throughput support of more than 1mps time-sensitive, critical messages such as bank account alerts, travel notifications, delivery updates, and OTPs.

Long numbers are less expensive than short codes and present an easy way for smaller businesses to integrate two-way SMS messaging into their business processes to improve customer service.

Long numbers are best for:

• Businesses with person-to-person message requirements of no more than one message per second.

• Appointment or booking reminders – for example, a restaurant sending an SMS reminder for a table reservation and receiving a confirmation back from the customer.

• Triggered messages based on processes – for example, for the Internet of Things (IoT) solutions where the user will respond with a command.

• Personalized messages based on customer interactions – for example, to confirm an order placed by a customer on your website.

Best practices

• The Mobile Marketing Association provides some useful trends and best practices for marketing to consumers via mobile.

• When sending messages to the US, you’ll need a long number or short code to deliver messages even if you do not want to receive replies. The reason for this is to ensure that customers can opt-out of your messages at any time as per the CTIA guidelines.

• Application-to-person (A2P) messages sent via long numbers may be subject to carrier filtering. It is generally recommended that long numbers are used for lower volume traffic at a maximum throughput of one message per second from a single long number to avoid possible carrier-end filtering. A Clickatell long number is limited to 5000 messages per day.

We’ve compiled some general best practices for SMS campaigns which you can read here.

Regulatory information

Consult your legal team to ensure that your opt-in and opt-out processes, message content and all other aspects of your message sending strategy comply with the applicable legislation to avoid your number from being blocked, or substantial fines imposed.

Cellular Telecommunications Industry Association (CTIA) represents the US wireless communications industry and companies throughout the mobile ecosystem. All short code usage should comply with a code of conduct as outlined in the CTIA Short code monitoring handbook.

The SMS-applicable rules adopted by the Federal Communications Commission (FCC) under the Telephone Consumer Protection Act (TCPA) became effective on October 16th of 2013 and you should also familiarize yourself with the regulations set out within this Act.

CAN SPAM - since you're reaching your customers directly on their mobile devices through text messages, it’s important that you follow the same rules of consent that you would when communicating with them via any other electronic medium.

Lastly, ensure that your use of two-way numbers is in line with the Clickatell terms and conditions.

It is therefore recommended that short code provisioning and amendments/migrations are done before the freeze period to avoid delays.

A Sender ID (from address) is the name or number that identifies the sender of an SMS message.

When a message is delivered to a mobile phone, the recipient may see any one of the following from address formats. This will indicate who the message came from.

• An international number such as +123456780.

• A local number.

• A short code (a short number, usually five or six digits only).

• An alphanumeric originator such as “Message”.

From addresses differ from country to country and carrier to carrier. This is because, in some countries, carriers block SMS messages that are sent from foreign numbers. To ensure delivery, the Sender ID is therefore changed to a local or otherwise acceptable number by Clickatell automatically.

Clickatell does not support custom alphanumeric Sender ID requests, but we do support short codes and long numbers as sender sources.
