Address Autofill

Automatic completion of address fields using browser data, saved profiles, or predictive address APIs

Checkout
Also known as:Address Autocomplete, Auto-fill, Type-ahead Address

Address Autofill automatically populates shipping and fields, reducing manual typing. Autofill sources include browser-stored addresses, account profiles, and predictive APIs that suggest addresses as users type.

Autofill Methods

Browser autofill: Uses addresses saved in Chrome, Safari, Firefox, or Edge. Triggered by properly labeled form fields.

Account profiles: Logged-in customers select from previously saved addresses.

Predictive autofill: APIs like Google Places suggest complete addresses as users type the first few characters.

Device autofill: Mobile keyboards offer saved address suggestions.

Why Autofill Matters

Typing full addresses on mobile devices creates friction and errors. Autofill reduces both:

Speed: Completing an address takes seconds instead of minutes.

Accuracy: Fewer typos and formatting errors mean fewer failed deliveries.

Mobile conversion: Particularly valuable on small screens where typing is tedious.

Enabling Browser Autofill

Browsers detect autofill-eligible fields through:

attributes: HTML attributes like autocomplete="address-line1" signal field purpose.

Field names: Standard names like "address," "city," "zip" help browsers identify fields.

Label text: Labels describing field content assist browser detection.

Common Autocomplete Values

  • name (full name)
  • email
  • tel (phone)
  • address-line1, address-line2
  • city or address-level2
  • state or address-level1
  • postal-code
  • country

Predictive Address Services

Google Places Autocomplete: Suggests addresses globally as users type.

Loqate: and autocomplete for international addresses.
