Enable Your Landline for Text Messages in GoHighLevel
If you manage client work in ClickUp and run your CRM and communications in GoHighLevel, enabling text messaging on your existing business landline keeps everything organized and professional. This guide explains how to convert a landline into a text-enabled number inside GoHighLevel so you can send and receive SMS using tools you already rely on.
The process uses Twilio’s hosted messaging service to add SMS capabilities to your landline without interrupting your voice service. You will complete a short verification, sign a Letter of Authorization (LOA), and wait for carrier approval before sending messages.
What You Need Before You Start in GoHighLevel
Before enabling your landline for SMS, make sure you have the following items ready so the GoHighLevel workflow goes smoothly:
- An active GoHighLevel account with admin access
- Your business landline number that you want to enable for text messages
- Access to the business owner or an authorized decision-maker
- Accurate business information (legal name, address, contact details)
- Email access for signing the LOA and receiving Twilio notifications
The system relies on your existing voice provider and Twilio’s messaging infrastructure. Voice calls will remain with your current provider while messaging is handled through Twilio inside GoHighLevel.
Step 1: Access the Phone Number Settings in GoHighLevel
To start the landline activation for SMS, log in and navigate to the phone settings area of GoHighLevel.
- Sign in to your GoHighLevel agency or sub-account.
- Go to Settings from the left navigation menu.
- Select the Phone Numbers section.
- Locate the option related to enabling an existing number or landline for text messages.
If the interface has been updated, the wording may vary, but you are looking for a path that begins the Twilio hosted messaging or landline SMS enablement flow.
Step 2: Submit a Request to Enable Your Landline for SMS
Inside the GoHighLevel phone settings, you will find a form or guided process that connects your landline to Twilio for hosted messaging.
Follow these general steps:
- Choose the option to enable an existing landline or local number for text messages.
- Enter your landline phone number in the required format.
- Provide the legal business name exactly as it appears with your phone provider.
- Add the business address, city, state, postal code, and country.
- Submit a primary contact name, email, and phone number for verification.
Ensure all details match your existing phone service records. Mismatched information can delay or prevent carrier approval, which impacts how quickly SMS will work in GoHighLevel.
Step 3: Complete the Letter of Authorization (LOA) for GoHighLevel Messaging
To allow Twilio to host messaging on your landline while keeping voice with your current carrier, you must sign a Letter of Authorization.
How the LOA Works with GoHighLevel
Once your initial request is submitted inside GoHighLevel, Twilio will send an LOA to the email address you provided.
Typical steps include:
- Open the LOA email from Twilio (or from the GoHighLevel support process, depending on configuration).
- Review the details: business name, landline number, and carrier information.
- Electronically sign the LOA as the business owner or authorized representative.
- Submit the signed LOA for processing.
This document confirms that you authorize Twilio to manage SMS messaging on your landline while your current provider continues to handle voice calls. This is a key step to connect your existing number to GoHighLevel for texting.
Step 4: Wait for Carrier Approval and Provisioning
After the LOA is signed and submitted, the request is reviewed by Twilio and your underlying carrier.
Typical Timeframes for GoHighLevel Landline Activation
- Processing times can vary by carrier.
- Most requests are handled in several business days.
- In rare cases, additional documentation may be required.
During this period, your landline voice service should remain uninterrupted. The only change is the activation of SMS through Twilio, which GoHighLevel will use for all text communication on that number.

Step 5: Verify SMS Functionality Inside GoHighLevel
Once Twilio and the carrier complete provisioning, your landline becomes SMS-capable in your GoHighLevel account.
Test Your Newly Enabled GoHighLevel Landline
- Log in to your GoHighLevel sub-account where the number is configured.
- Go to Settings > Phone Numbers to confirm the status of the landline.
- Ensure the number appears as active and enabled for messaging.
- Send a test text message to a mobile phone from a conversation or campaign using this number.
- Reply from the mobile phone and check if the response appears in the GoHighLevel conversations area.
If messages send and receive correctly, your landline SMS setup is complete.
