## Tips

* Double-check your EIN and business name for accuracy
* 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
* Identify your official business address (cannot be a PO Box or dev URL)
* If you have multiple brands, register each separately
* If registration is rejected despite a compliant website, [contact support](https://support.quo.com/help/submit-a-request) for Twilio clarification on the rejection reason

<Tip>
  Having a consistent online presence (Google Business Profile, social media, business listings) helps strengthen your registration application.

## 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](https://support.quo.com/help/submit-a-request) can submit a manual request behalf, but cannot guarantee approval.

## FAQs

<AccordionGroup>
  <Accordion title="I completed my carrier registration as sole-proprietor, is it possible to re-register as a business?">
    Not directly. To switch, you’ll need to delete your current registration and re-register as a business.

    A couple things to know:

    * Messaging may be briefly paused during the switch
    * The carrier review fee applies again

    Sole proprietor and business registrations are treated as completely separate by carriers, so there’s no way to convert or transfer an existing registration
  </Accordion>

  <Accordion title="My Caller ID was rejected because my business name doesn't match my registration. What can I do?">
    If you're using a secondary or DBA name, you'll need documentation linking it to your registered name (e.g. a DBA filing or name change certificate). [Contact support](https://support.quo.com/help/submit-a-request) and we'll submit a manual request to Twilio on your behalf. Approval is not guaranteed.
