GoHighLevel CNAM Setup Guide

If you use ClickUp or any other project management tool alongside GoHighLevel, understanding how CNAM works is essential for managing phone systems professionally. CNAM (Caller ID Name) lets you display a business name instead of just a phone number when you place outbound calls. This guide explains what CNAM is, how it works in GoHighLevel, and what you must do to enable it correctly.

What Is CNAM in GoHighLevel?

CNAM stands for Caller ID Name. It is the feature that allows the receiving party’s phone to display a text name (such as your business name) in addition to, or instead of, your phone number.

In the context of GoHighLevel, CNAM determines what name your contacts see when you call them from your GoHighLevel phone numbers. Instead of a generic or unknown label, a properly configured CNAM can show a recognizable business identity.

CNAM data is stored and controlled by the terminating phone carrier, not directly by GoHighLevel. When you place a call, the carrier receiving the call looks up the associated CNAM record and displays it on the recipient’s device, if supported.

How CNAM Works with GoHighLevel Phone Numbers

When you purchase or use phone numbers inside GoHighLevel, those numbers are powered by an upstream carrier. CNAM is linked to each individual phone number. The process works as follows:

• You register a Caller ID Name for a specific phone number.
• The CNAM entry is stored in a national or regional database accessible to carriers.
• When you call someone, the terminating carrier queries that database.
• If a CNAM record exists and the carrier supports it, your chosen name is shown.

Because the terminating carrier controls what is displayed, GoHighLevel itself cannot guarantee that CNAM will always appear on every call. Some carriers or devices may show only the phone number, or they may override the CNAM with their own data.

Requirements for CNAM in GoHighLevel

Before setting up caller ID names, there are key requirements and limitations you should keep in mind. These come from how carriers handle CNAM, not from GoHighLevel alone.

GoHighLevel CNAM Character and Format Rules

• CNAM is generally limited to a maximum of 15 characters (including spaces).
• Use only letters, numbers, and standard spaces. Avoid special characters and symbols.
• The name must represent a real business or individual; carriers may reject misleading or fake names.

Because of the character limit, you may need to abbreviate your company name while keeping it recognizable to your contacts.

GoHighLevel CNAM Carrier and Device Limitations

• Not all carriers support CNAM display for wireless or VoIP devices.
• Some carriers rely on their own internal databases and may show a different name than the one you registered.
• Certain devices may display only the phone number or a location instead of the CNAM text.

These limitations apply regardless of whether calls are made through GoHighLevel or any other phone platform, because they are enforced at the carrier level.

How to Enable CNAM for a Number in GoHighLevel

The exact configuration options for CNAM registration are handled through the telephony backend used by GoHighLevel. The high-level process is as follows:

1. Choose the phone number
   Select the specific phone number in your GoHighLevel account that you want to use for outbound calls with a branded caller name.

2. Prepare your Caller ID Name
   Ensure your desired CNAM value:

   • Is 15 characters or fewer.
   • Contains only allowed characters (letters, numbers, spaces).
   • Accurately represents your business or personal identity.

3. Submit CNAM through your telephony settings or support
   Depending on the configuration options currently available in your GoHighLevel environment, you may:

   • Use an integrated telephony settings panel (if available), or
   • Work with support to request CNAM registration for your specific number.

4. Wait for carrier propagation
   After CNAM is submitted, carriers need time to update their databases. This can take several days, and the time frame varies by carrier.

5. Test calls to multiple carriers
   Place outbound test calls from GoHighLevel to different phone providers (mobile, VoIP, landline) to verify whether your CNAM is displayed and how it appears.

For reference, you can review more information directly from the original GoHighLevel CNAM article at this official support page.

Best Practices for GoHighLevel CNAM Setup

To get the most reliable results from your caller ID configuration, follow these recommendations when working with GoHighLevel phone numbers.

Use a Clear, Recognizable GoHighLevel Caller Name

• Choose a name that your customers can immediately recognize.
• If your business name is long, use a shortened version that still clearly relates to your brand.
• Avoid generic terms such as “Customer Service” that could look suspicious or spam-like.

Align GoHighLevel CNAM with Compliance Rules

• Use only truthful and accurate business names.
• Do not imitate another company’s identity.
• Follow all local, national, and carrier-specific telephony regulations.

Proper compliance helps reduce the risk of your calls being flagged or blocked by carriers or spam detection systems.

Monitor GoHighLevel Call Results

• Ask internal staff or trusted contacts on different carriers to confirm what they see when you call.
• Document differences by carrier or device type.
• Update your CNAM if you rebrand or change your business name.

Troubleshooting CNAM Issues in GoHighLevel

Because CNAM display is controlled by the terminating carrier, there are common issues you may encounter when using GoHighLevel for outbound calls.

GoHighLevel Caller Name Not Showing

• CNAM propagation may not be complete yet; wait several days after registration.
• The receiving carrier may not support CNAM or may use its own database.
• The recipient’s device or plan may not display caller ID names by default.

In many cases, the CNAM record is correctly registered, but the final display is limited by the recipient’s carrier policies or device settings.

Incorrect GoHighLevel Name Displayed

• Some carriers maintain outdated or conflicting CNAM records.
• The carrier may substitute a location or previously stored name.
• Contacting the relevant carrier may be required to correct mismatched data.

Because this behavior is external to GoHighLevel, resolving it may require coordination with carriers or telephony providers.

Additional Resources Beyond GoHighLevel

To deepen your understanding of CNAM behavior and improve your telephony strategy, you can:

• Review the official GoHighLevel documentation on CNAM at the support knowledge base.
• Consult a telecom or marketing operations specialist for complex, high-volume setups.
