Got questions? We've got answers!

  • What is a short code?

    Short codes are network specific access codes used for sending and receiving messages (both SMS and MMS) between consumers and companies. Short codes are shorter than a normal mobile phone number and usually consist of three to eight digits, depending on the country. 

  • What’s the difference between virtual long numbers and short codes?

    The main difference between these two sender types is how they’re intended to be used. Virtual long numbers were designed to support P2P messages with a relatively low throughput of messages. Short codes were designed to support A2P bulk, higher throughput messaging – this is a preapproved route, which eliminates filtering. 
    Over time, demand for and use of messaging channels has changed and carriers have stepped in to get better control of the traffic on their networks in an effort to increase security and deliverability.

  • Do I need a virtual long number or short code?

    For most countries, you will only need a virtual long number or a short code if you wish to engage in two-way interactions with your customers. If you do not wish to engage in a two-way dialogue, then in most countries you can simply set the Sender ID (Originator) to something alphanumeric using your brand name, e.g. ‘Sinch.’ 
    However, in some countries like  the US and Canada, a short code or toll-free number is required regardless, as alphanumeric Sender IDs are not supported. For more information, please contact your Account Manager. 

  • Where do I get a short code?

    Sinch can assist in obtaining a short code in many countries. For the US, we recommend you go directly to the US Common Short Codes and obtain your short codes. Once the short code has been leased, the short code and the associated campaign(s) can be submitted for carrier approvals. 
    For short codes in other countries, please contact your Account Manager.

  • What attributes of a short code do I need to be aware of?

    In some countries using a short code Sender ID is mandatory to ensure the identity of the message sender is known at all times for compliance reasons and an opt-in MNO message must be sent first.     

    Similarly, in order to comply with local regulations, in some countries, certain keywords must be supported, e.g. STOP, INFO, and HELP. 

    Keep in mind short codes will only work on local domestic phones of the country of the short code, even while roaming abroad. 

  • Why are short codes popular and can they be used globally?

    They’re popular because they're memorable and hence easier to enter into a phone. They can also spell out memorable brand names. 
    Short codes are typically country specific; i.e., you need a short code per country and they rarely overlap across countries.
