This article focuses on **Outbound CNAM** — how it works, how to manage it, and what to do if your caller ID name isn’t displaying as expected. **What is Outbound CNAM?** **Outbound CNAM** (also called *outbound caller ID name* or *CNAM storage*) lets you assign a custom name to one of your phone numbers. This name is stored in a national CNAM database and can appear on the receiving party’s caller ID when you make calls. Example: You’ve set your phone number 412-200-7430 to display as "XYZ COMPANY." When you call someone, they should see "XYZ COMPANY" on their screen. **How It Works** - When you place a call, the receiving phone provider performs what's called a **CNAM dip**, which means they look up your caller name in a central database. - Even if a caller name is sent in the SIP header (the "From" field), it’s **not guaranteed** to be shown—this info can be removed once the call travels through the public phone network (PSTN). - The **receiving phone provider** (like Verizon, AT&T, etc.) is ultimately responsible for showing the caller name—not Voiply. **Things to Know** - **Caller ID name display is not universal** — it can vary by carrier, and some carriers cache outdated records. - If the wrong name appears, the only way to correct it is by opening a support ticket with the **receiving carrier**. - Not all Voiply phone numbers (DIDs) support Outbound CNAM. Be sure to choose compatible numbers when purchasing or porting. **CNAM Propagation & Update Timeline** **Please allow up to 48 business hours** for CNAM changes to fully take effect. *Note:* Some phone carriers cache old records, so the previous name may still appear temporarily—even after it's been removed. **What Happens When You Update CNAM** 1. **Instant Save:** Your CNAM change is saved in Voiply's system right away. 2. **Vendor Sync:** Updates are sent to our CNAM provider—usually overnight. 3. **Propagation Time:** It can take up to **48 business hours** for the new name to fully appear in CNAM lookup (dip) results. If you open a ticket, we’ll review the timestamp of your update and take action if the info hasn’t reached our vendor properly. **CNAM Character Limit** - CNAM names are limited to **15 characters**, including spaces. • Longer names are **automatically shortened** (e.g., "ABCDEF GHIJKL MNO" becomes "ABCDEF GHIJKL"). This is a **national standard** that applies across all carriers—not a Voiply limitation. **Final Tips** - **No extra fees** for using Outbound CNAM—just choose a compatible number - **Caller name display is controlled by the receiving carrier** (e.g., Verizon, AT&T) - **Changes take time**—wait 48 business hours before assuming there's an issue - **Still seeing the wrong name?** Open a ticket with the carrier showing incorrect info Need help verifying your Outbound CNAM? 📨 [**Contact our support team**](https://kb.voiply.com/how-do-i-contact-voiplys-support)—we’re happy to help! - [Getting Started](https://kb.voiply.com/getting-started#main-content) - [Account Setup & Verification](https://kb.voiply.com/getting-started#account-setup-verification) - [Billing Basics](https://kb.voiply.com/getting-started#billing-basics) - [Calling and Service Limitations](https://kb.voiply.com/getting-started#calling-and-service-limitations) - [Features & Enhancements](https://kb.voiply.com/getting-started#features-enhancements) - [Network Setup](https://kb.voiply.com/getting-started#network-setup) - [Using the Voiply Mobile App](https://kb.voiply.com/getting-started#using-the-voiply-mobile-app) - [Porting Your Number](https://kb.voiply.com/porting-your-number) - [Home Phone Service](https://kb.voiply.com/home-phone-service#main-content) - [Cancellation and Returns](https://kb.voiply.com/home-phone-service#cancellation-and-returns) - [Troubleshooting](https://kb.voiply.com/home-phone-service#troubleshooting) - [Billing and Payments](https://kb.voiply.com/home-phone-service#billing-and-payments) - [Account Management](https://kb.voiply.com/home-phone-service#account-management) - [Getting Started](https://kb.voiply.com/home-phone-service#getting-started) - [Kids Phone Service](https://kb.voiply.com/kids-phone-service) - [Business Phone Service](https://kb.voiply.com/business-phone-service#main-content) - [Starter Plan](https://kb.voiply.com/business-phone-service#starter-plan) - [The Essentials](https://kb.voiply.com/business-phone-service#the-essentials) - [Premier Plan](https://kb.voiply.com/business-phone-service#premier-plan) - [Number Parking](https://kb.voiply.com/number-parking) - [Internet Service](https://kb.voiply.com/internet-service) - [Online Fax Service](https://kb.voiply.com/online-fax-service) - [Premium Add-ons](https://kb.voiply.com/premium-add-ons) - [AI Receptionist](https://kb.voiply.com/ai-receptionist) - [AI Assistant](https://kb.voiply.com/ai-assistant) [![Chill listening crop-3](https://kb.voiply.com/hs-fs/hubfs/logo_1-removebg-preview.png?width=60&height=24&name=logo_1-removebg-preview.png "Chill listening crop-3")](http://www.voiply.com) 301 Grant St #270, Pittsburgh, PA 15219 [mailto:support@voiply.com](mailto:support@voiply.com) Copyright © 2025, Voiply, LLC
