GoHighLevel Phone Error Code & Warning How-To Guide

If you use ClickUp to manage tasks and rely on the GoHighLevel phone system for calling and texting, understanding system errors is essential. This how-to guide explains how to read, interpret, and respond to GoHighLevel phone error codes and warnings so you can quickly diagnose issues and keep your communication running smoothly.

The instructions below are based on the official LC Phone System Error Code and Warning Dictionary. Use this as a practical reference whenever you see an unfamiliar error in your account.

How the GoHighLevel Phone System Shows Errors

The GoHighLevel LC phone system reports issues through:

• Error codes on calls and texts
• Warning messages inside the app
• Status notes like “undelivered” or “failed” next to messages

Each error or warning usually points to a specific problem, such as carrier filtering, invalid numbers, or configuration issues. By matching the message you see to the descriptions in this guide and the official GoHighLevel LC Phone System Error Dictionary, you can decide what to fix next.

Step-by-Step: How to Use the GoHighLevel Error Dictionary

Follow these steps whenever the GoHighLevel phone system shows an error on a call or SMS/MMS.

Step 1: Locate the Exact GoHighLevel Error Message

1. Open your GoHighLevel account.
2. Go to the conversation, call log, or workflow where the issue occurred.
3. Look for an error label, status badge, or warning tooltip next to the call or message.
4. Note the exact error phrase or code, including any numbers or short descriptions.

Having the exact wording is important because similar errors may have different causes and solutions.

Step 2: Match the Error to the GoHighLevel Dictionary

1. Open the LC Phone System Error Code and Warning Dictionary in a new tab.
2. Use your browser’s find function (Ctrl+F or Cmd+F).
3. Search for the main term from the error (for example, “unreachable”, “blocked”, or “invalid number”).
4. Read the related entry to understand what the error means and which side (your number, your contact, or the carrier) is causing the issue.

This process helps you quickly identify whether the problem is technical, compliance‑related, or data‑related.

Step 3: Apply the Recommended Fix

Based on the description in the GoHighLevel error dictionary, take the recommended action. Common actions include:

• Correcting or reformatting a contact’s phone number
• Removing unsupported characters or media from a message
• Checking your phone number configuration inside the LC phone settings
• Reducing the frequency or volume of similar messages if they might be flagged as spam
• Ensuring you comply with carrier and local messaging regulations

After making a change, send a new test message or place a test call to confirm that the error no longer appears.

Common GoHighLevel Phone Error Scenarios

While each specific error code has its own definition, most issues fall into a few common categories. Use these scenarios to decide where to look first.

Invalid or Unreachable Numbers in GoHighLevel

Some errors indicate that the destination number is wrong, inactive, or unreachable.

Typical signs include:

• Repeated delivery failures to the same contact
• Error messages referencing “invalid number”, “unreachable”, or “unknown subscriber”

How to handle:

• Double‑check the country code and number format.
• Confirm with the contact that the number is correct and active.
• Update the contact record in GoHighLevel before retrying.

Content or Compliance Issues in GoHighLevel Messages

Other errors and warnings originate from carrier or compliance filters. These can affect both one‑to‑one and bulk messages.

Warning signs include:

• Messages marked as “filtered” or “blocked by carrier”
• Errors that mention prohibited content or policy violations

How to handle:

• Avoid spam‑like patterns such as repeated identical messages to many contacts.
• Include clear opt‑out language when required.
• Remove harmful, misleading, or disallowed content from SMS campaigns.
• Monitor deliverability rates after each change.

Configuration Problems in the GoHighLevel LC Phone System

Some GoHighLevel errors point to a configuration or account setup issue rather than a contact or content problem.

Indicators include:

• No calls or texts go through from a specific number
• Errors referencing phone number capabilities, registration, or configuration

How to handle:

• Open your LC phone or number settings.
• Verify that the number is active and supports the type of traffic (voice or SMS) you are sending.
• Ensure numbers are properly assigned to workflows, pipelines, or users where needed.

Best Practices for Preventing GoHighLevel Phone Errors

While you can always troubleshoot individual issues with the error dictionary, it is more efficient to prevent recurring problems. Use these best practices when building and maintaining your GoHighLevel workflows.

Validate Contact Data Before Using GoHighLevel Automation

• Require valid phone numbers when capturing leads.
• Clean historical data and remove obviously invalid or incomplete numbers.
• Periodically review high‑error contacts and correct or remove them.

Write Carrier‑Friendly Messaging Content in GoHighLevel

• Keep messages concise and clearly related to the contact’s expectations.
• Avoid excessive links, all‑caps text, or repeated use of promotional terms.
• Include identity and purpose in your first outreach so contacts recognize who you are.

Monitor GoHighLevel Error Trends Over Time

• Review recent errors in your conversations and call logs each week.
• Identify patterns such as one campaign or number generating most of the issues.
• Adjust sending windows, volume, or content based on what you find.

When to Contact GoHighLevel Support

If you have followed the steps above and matched the message to the dictionary but the same error keeps appearing, it may be time to contact support.

Before opening a ticket, prepare:

• Screenshots of the exact GoHighLevel error or warning
• The date, time, and timezone for the affected calls or messages
• Sample phone numbers (with sensitive data shared securely)
• A brief description of what you already tried based on the LC error dictionary

This information helps support review your case more quickly and compare it with carrier‑level logs if needed.
