What a short code is
A 5- or 6-digit sender (like 32665) that companies use to send codes in bulk. They’re country-specific: a US short code only reaches numbers on US carriers.
Who receives them
Mobile numbers on carrier networks usually do. Many VoIP numbers don’t, which is a common reason a code “was sent” but never shows up. Most CoveSMS numbers are mobile and receive short codes.
If a short-code SMS doesn’t arrive
- Pick a number from the same country as the app’s sender
- Try the other server: different number pools, different carriers
- Remember the balance back: no code in 20 minutes, no charge
