It might be that they want to align their onboarding process across territories, so apply the same admin load for all countries.<\/p>\n\n<p>Or it could be that they\u2019re just not familiar with the regulations in the UK.<\/p>\n\n<h2><strong>What are the rules for using sender IDs in the UK?<\/strong><\/h2>\n\n<p>SMS A2P users are free to use any alphanumeric sender ID they wish as long as it\u2019s not restricted by the UK mobile networks. (There\u2019s a maximum of 11 characters or 15 numeric characters.)<\/p>\n\n<p>There is a large list of restricted sender IDS that users may not use. The list includes many banks and financial institutions as well as major high street and well known brands.<\/p>\n\n<p>These sender IDs are restricted to help prevent fraud, where criminals impersonate brands and attempt to direct users to fraudulent websites.<\/p>\n\n<p>The list of restricted sender IDs is obviously not published as it would allow criminals to bypass the restricted sender IDS but still attempt their scams.<\/p>\n\n<p><strong><a href=\"https:\/\/mobileecosystemforum.com\/\">The Mobile Ecosystem Forum (MEF),<\/a><\/strong> a mobile industry body, runs a service called the <strong><a href=\"https:\/\/mobileecosystemforum.com\/sms-senderid-protection-registry\/\">SMS Sender ID protection Registry.<\/a><\/strong> This initiative informs registered organisations with all the existing and newly restricted sender IDs.<\/p>\n\n<p>It\u2019s a great way of keeping the SMS industry informed of new sender IDs that fraudsters have attempted to use dishonestly.<\/p>\n\n<h2><strong>What happens if I try to send a text with a restricted Sender ID?<\/strong><\/h2>\n\n<p>If you send a message with a restricted sender ID, then your text will simply not be delivered.<br \/>We always recommend testing your messages before using them in a live environment.<\/p>\n\n<p>As long as you\u2019re not doing anything that could be interpreted as suspicious, then you are unlikely to encounter any issue with deliverability.<\/p>\n\n<h2><strong>BT \/ EE have additional sender ID restrictions<\/strong><\/h2>\n\n<p>BT \/ EE have brought out their own rules for sender IDs that they have applied to messages being delivered on their network.<\/p>\n\n<p>Generic sender IDs like Bank or Banking have been banned.
