Text messages, letters and communications

Join the free Scottish Government text messaging service

We can text important updates to your mobile phone. To join, text your Community Health Index (CHI) number to 07860 064525. Your CHI number is the 10-digit number at the top of your letters from the NHS and the Chief Medical Officer. If you get a new phone number, text us your CHI number from your new phone to update your details.

We'll never ask for your personal or banking details by text. If you receive a suspicious text message, you can report it by calling Police Scotland on 101.

How to opt out of our text message service

You can stop receiving text message updates from the SMS service at any time. To do so, text STOPMESSAGE to 0786 006 4525. You will remain on the highest risk list.

If your address changes

If you change address, ask your GP practice to update the details they hold for you. They’ll pass your new details to us. If your letters still go to the wrong place email Use the subject line 'Change to highest risk list details'. Include your full name, CHI number and new address.

Past letters and other communications to people at highest risk

You can find past letters we sent to people at highest risk at The page also includes other communications for the highest risk group, like videos. You'll find other languages and formats there too.

All these letters and communications were correct at the time they were sent or published. But they may now be out of date. Find the latest Scottish Government advice to people at highest risk from Covid here on
