These are the most common errors and statuses when creating a WhatsApp channel in 2Chat, and how to solve each one yourself.
Number in the wrong format
"Please make sure the number is valid and using international format"
The number is not in international format or does not have WhatsApp enabled. Enter it as country code + number (e.g. +1 555 013 4567) and make sure the number has a WhatsApp account.
Number used previously
"The number you are trying to add already exists. If you or your team didn't add this number before, please get in touch with us."
The number is already used by another channel, even in another account. Check whether you have another channel with the same number; if you don't, contact our support team.
The channel shows "Configuration required"
Your channel was created but its setup is not finished:
"This number hasn't been configured yet. Start the configuration process to send and receive messages."
Click the Configuration required button in the Status column of the channel list (or open the channel and click Start configuration). The Setup Wizard finishes the registration for you.
The number's link with Meta is out of date
"This number's link with Meta is out of date: the number no longer exists in your Meta account, or 2Chat lost access to it. Retrying won't fix it."
This happens when the number was removed or changed on Meta's side after the channel was created. Retrying will never fix it. Click Delete channel & reconnect in the setup — 2Chat deletes the channel and takes you straight to connecting the number again. You do not need to deregister anything first, and nothing changes in your Meta account.
Too many registration attempts
"Too many registration attempts for this number. WhatsApp allows 10 per 72 hours — please try again later."
This is a WhatsApp limit, not a 2Chat error. The setup shows an estimate of when you can retry ("You should be able to try again around {time} — often sooner") and a Try again button. You don't have to wait watching the screen: 2Chat keeps retrying in the background and the registration completes on its own. Retrying many times without fixing the underlying cause can temporarily block the number, so if an error is shown above the button, solve that first.
Sending is capped until your business is verified
"Your number is connected and can send messages now. Until Meta verifies your business, new conversations you start are capped at 250 per 24 hours — replies to customers who write to you are unlimited."
This is not an error and the channel is not blocked — it works. Meta caps business-initiated conversations at 250 per 24 hours until your business completes business verification in Meta Business Manager. Replies to customers who message you first are unlimited. Complete the verification to lift the cap.
The Meta window doesn't open
"Your browser blocked the Meta window. Please allow pop-ups for this site and try again — or use Chrome if it keeps happening."
Allow pop-ups for app.2chat.io in your browser and start the connection again. If it keeps happening, try from Chrome on a computer.
The Meta signup didn't finish
If you see "Your WhatsApp signup session expired. Please start the connection again." or "We didn't get a complete response from Meta. Please close the Meta window and try again.", close the Meta window and start the connection again from the beginning, completing every step of the Meta window without closing it early.
