# Texts won't send

> The usual reasons a message won't go through, and the quick fix for each.

When a text won't send, it's usually down to one of a handful of reasons: registration, a blocked contact, an unsupported country, or a message that failed on the way. Here's the quick version, with the full guide (covering registration, identity checks, and fair usage) over on [When texts won't send](/messaging/message-deliverability).

Run through these in order:

* **Texting a US number?** You need to register first. Carriers require every number to be registered before it can text US and Canadian phones. See [Carrier registration](/getting-started/carrier-registration/overview).
* **Blocked contact?** If you've blocked them, your texts won't go through. Unblock them from the **⋯** menu in the chat, or from **Settings**, then **Blocklist**. See [Blocklist](/admin/blocklist).
* **Wrong country?** Dialbird only texts certain countries. See [Texting other countries](/messaging/international-messaging).
* **A message shows "Not delivered"?** Something went wrong in transit. Click **Retry** next to the message to send it again.

If you've worked through all four and a text still won't go, [get in touch](/support/submit-a-request) with the number you were texting and what the message showed, and we'll take a look.
