Why am I not receiving my SMS login code?Updated 2 days ago
TL;DR: Sign-in codes only go to contact details that are already on your account, so if your SMS code is not arriving it is almost always because your mobile number is not linked yet. Sign in with an email code instead, then add your number in your account settings. SMS codes will work from the next sign-in.
Most likely cause

Why am I not receiving my SMS login code?
Sign in with email instead
On the sign-in screen, choose to send the code by email rather than SMS. Check your inbox, and your spam folder, for the one-time code.
Add your mobile number to your account
Once you are signed in, open your account settings and enter your mobile number in your contact details.
SMS works from the next sign-in
With your number on the account you can choose SMS at sign-in and the code will arrive by text, with no inbox or spam folder to check.
What if my email code is not arriving either?
If your email code is not arriving either, check the following:
- Spam, junk or promotions folder, where codes often land on a first sign-in
- The right email address, because the code only goes to the address on your account
- Wait a couple of minutes, as short delivery delays are normal
- Request a new code from the sign-in screen. The new one replaces any earlier code
If none of that helps, contact the Koh UK team with the email address and mobile number on your account.
Why link a mobile number at all?
✓ Usually faster than email
Text messages arrive quickly and are never filtered into a spam or promotions folder.
✓ A second way back in
If you lose access to your inbox you still have a working route to sign in. That matters, because the email address on a Koh account cannot be changed once the account exists.
