Short codes are ideal for high-throughput (100 messages per second by default) programmatic messaging. Short codes are approved for specific use cases, so if you are experiencing carrier filtering on long codes you may be a good candidate for short codes.
Some of the most common use-cases for short codes in the UK include:
Short codes can only message users on carriers within the countries in which they are provisioned. AlthoughTwilio can provision short codes in multiple countries, if your customers are not located in the UK, you should not obtain a UK short code.
Short codes require express consent from end users before any SMS can be sent; if you cannot obtain consent then you should not use a short code.
Twilio and/or the carriers will not support certain types of campaigns, including:
Note: Campaigns dealing with age-restricted content (alcohol, gambling, etc.) are allowed, but will be evaluated on a case-by-case basis by UK carriers.
Traditional long-code or toll-free SMS are the best alternatives.
