Got questions? We've got answers!

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

    The main difference between these two numbers is how they’re intended to be used. Long numbers were designed to support person-to-person (P2P) messages with a relatively low throughput of messages. Short codes (SC) were designed to support application-to-person (A2P) bulk, higher throughput messaging – this a preapproved route, which eliminates filtering. 
     
    Over time, demand for and use of messaging channels has changed. A2P messages are being sent on long codes, and some short code-based campaigns support P2P-like experiences with the application only hosting the consent and communication experience. The 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’. 
     
    In some countries, however, like the U.S. and Canada, a short code or toll-free number is required regardless of whether you want to engage in a two-way dialogue, as alphanumeric Sender IDs are not supported. For more information about which countries require a short code or virtual long number, please contact your Account Manager.
