California: the licence number in your emails
California Insurance Code section 1725.5(c) requires licensees to include their licence number in emails that involve an activity a licence is required for.
- No smaller than the largest phone number, street address or email address in the email.
- Next to, or on the line below, your name or title.
- For an organization's email, next to or below the organization's name.
California: cards, quotes and print ads
Section 1725.5(a) also requires the licence number on business cards, written price quotations and print ads distributed only in California: at least as large as any phone number, address or fax number, or 12-point type (8-point on business cards), whichever is larger.
Section 1725.5(b) requires the word “Insurance” on the same items, at least as large as the smallest phone number, or 12-point type (8-point on cards), whichever is larger.
Other states
Rules differ from state to state. Check with the insurance department in each state you're licensed in. This page describes California's rule; it isn't legal advice.
Aicopack's email signature
Aicopack builds a signature from your profile: your name, title and photo, your phone and email, a link to your page, and a licence line from the first licence you entered with a number (its state, line and number), or your NPN.
Copy it into Gmail or Outlook. Check the size and placement against your own state's rule: Aicopack doesn't check your signature for you.
