Tips

- Confirm the business name on your website matches your registration
- Check that your website phone number and address match what you’re submitting
- Ensure your website shows a clear product or service

Caller ID names and business names
The name you use for Caller ID must match the business name on your carrier registration. If you operate under a secondary or DBA business name that differs from your registration, the Caller ID submission will be rejected. To use a secondary name, you’ll need to provide documentation linking the two names (e.g. a DBA filing or name change certificate). Quo can submit a manual request behalf, but cannot guarantee approval.FAQs
