This guide covers the full account onboarding flow — collecting user information, submitting the account, and handling edge cases.

​
Overview

Account creation requires four data groups:
  1. Contact — Email, phone, mailing address
  2. Identity — Legal name, date of birth, tax ID, citizenship
  3. Disclosures — Regulatory disclosures (control person, political exposure, etc.)
  4. Agreements — Account and customer agreements with timestamps and IP address

​
Collecting data in your UI

You don’t need to collect all data on a single screen. A common pattern: 
Screen 1: Name, email, phone
Screen 2: Address
Screen 3: Date of birth, SSN, citizenship, funding source
Screen 4: Disclosures (yes/no checkboxes)
Screen 5: Agreement review and signature
Submit the account once all data is collected.
