Customer Properties - Upstack Data

Customer properties are used for identity resolution and destination matching. Including these fields significantly improves match quality on advertising platforms.

Properties

email

Primary cross-device identifier.

phone

E.164 format phone number.

firstName / lastName

Customer name fields.

Address Fields

Shipping and billing address.

Quick Reference

Property	Type	Required	Description
`email`	string	Recommended	Customer’s email address
`phone`	string	No	Phone number (E.164 format recommended)
`firstName`	string	No	Customer’s first name
`lastName`	string	No	Customer’s last name

Example

window._upstack('track', 'lead', {
  email: 'customer@example.com',
  phone: '+15551234567',
  firstName: 'Jane',
  lastName: 'Smith',
  value: 0,
  currency: 'USD'
});

Events that include an email match far more reliably on Meta than events with only an IP address.

Privacy

All customer PII (email, phone, name) is normalized and SHA-256 hashed before being sent to advertising destinations. Raw values are never stored in destination platforms.
