Some services require you to explicitly allow messages. To do this:

1. Open your messaging app.
2. Send the word “ALLOW” to the shortcode (e.g., “12345”).
3. Wait for confirmation or retry the action that prompted the shortcode message.

If you aren’t receiving messages from a shortcode you need, here’s what to check:

1. Make sure the shortcode Isn’t blocked

Android

1. Open the Messages app.
2. Tap the three dots (⋮) or More Options in the top-right corner.
3. Go to Settings.
4. Tap Blocked Numbers.
5. Look for the shortcode (e.g., “12345”) and unblock it.

iPhone

1. Open the Settings app.
2. Navigate to Messages.
3. Tap Blocked Contacts.
4. Find the shortcode and swipe left to unblock it.

2. Check your phone’s settings

iPhone

1. Go to Settings.
2. Tap Messages.
3. Make sure Send as SMS is enabled.
4. Check if Filter Unknown Senders is on. If it is, messages from shortcodes might appear in the Unknown Senders tab.

3. Verify the shortcode

Double-check that the company is using the correct shortcode. Mistyped numbers can cause issues.

• Be cautious: Avoid responding to unknown shortcodes asking for personal information or money—they could be scams.
• Save trusted shortcodes: If you frequently interact with certain shortcodes, save them in your contacts for quick recognition.
