# When texts won't send

> What stops a text going out, from a single failed message to texting being switched off, and how to fix each one.

Now and then a text will not go out. Sometimes it is a single message that fails, and sometimes texting is switched off before you have even typed. This page covers both, and how to get going again.

## A text that failed

If a message does not go through, it shows in the chat with a red warning and the words **Not delivered.**

Click **Retry** next to it to try again.

## Things that stop texting altogether

Sometimes the message box itself is switched off before you have even typed. Dialbird shows a banner at the top telling you why.

### You need to register to text US numbers

American phone companies will not accept business texts from a number that has not been registered. Until you have done it, you will see:

> US carriers require A2P 10DLC registration before you can send messages to US phone numbers.

Click **Register Now**, which takes you to the **Trust Center**. See [Carrier registration](/getting-started/carrier-registration/overview).

This only affects texting **US numbers**. If you are only texting UK customers, it does not apply.

If your account is registered as a **sole proprietor**, there is an extra limit: only one number can carry your A2P messaging. If you try to use a second, Dialbird tells you the sole-proprietor allowance is already taken by another number.

### Your number needs its identity checks

Some numbers need identity checks (called KYC) before they can call or text. You will see:

> Complete KYC verification to keep calling and messaging on this number. It takes less than 5 minutes.

Click **Complete KYC** and follow it through.

### You've hit the fair usage level

Every workspace has a fair usage level for texting. If you go over it, texting is switched off for a while and the message box is blocked. Open the notice and click **Contact support**, and we will look at it.

## Other reasons a text won't send

If a single message will not send, the reason is usually one of these:

| What you see                                       | What it means                                                                                                               |
| -------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------- |
| Your workspace can't send messages to this country | You can't text that country. See [Texting other countries](/messaging/international-messaging).                             |
| Enter a valid phone number to send a message.      | Check the number.                                                                                                           |
| This contact is blocked                            | You've blocked them. Unblock them from the **⋯** menu in the chat, or see [Blocking contacts](/contacts/blocking-contacts). |
| Failed to send message. Please try again.          | Something went wrong. Try **Retry**.                                                                                        |

<Note>
  Dialbird doesn't show you "delivered" or "read" ticks on a text. The only thing it tells you is when a message **fails**. No red warning means it went out fine.
