Frequently Asked Questions

An address autocomplete is a functionality used in online forms and mapping applications to assist users in entering addresses in the right format.

When a user types an address in a form field or search bar, the autocomplete system suggests potential matching results based on relevance or proximity to the user’s location.

The address autocomplete functionality typically leverages a database or an API that contains a vast collection of valid addresses, postal codes, cities, states, and countries. As users begin typing in their address search, the system predicts and suggests potential matches based on the input provided, making it easier for users to select their valid address from the suggestions rather than manually entering the complete address. 

Choosing carefully your address autocomplete software is important. For instance, a a user inputs 185, Fift Avenue, although no residence exists with that number on the specified street – with only two existing apartments numbered 183 and 186 – many address autocomplete tools ignore these errors and proceed to fill in the remaining address details. 

Consequently, this oversight often results in unsuccessful or undelivered shipments.

The Address autocomplete validation process ensures that users receive suggestions as they type, and validate the correct address data to ensure it is real and accurate.

This validation process checks aspects such as:

  • Presence of typos or misspellings in street address
  • Existence of the address in a valid postal or mapping database
  • Formatting of the address being properly standardized to match postal standards

Address Autofill and Address Autocomplete are closely related concepts, but they have some data sourcing differences:

Address Autofill

Address Autofill typically refers to the automatic population of address fields in a form by filling in address details based on information the user has previously provided or saved in their profile. It doesn’t necessarily involve real-time suggestions or predictions as the user types. It is commonly used in e-commerce websites, online checkout processes, and address entry forms.

Address Autocomplete

Address Autocomplete provides real-time address suggestions based on the characters entered by the user. This can be especially useful when users are unsure of the exact address format or need to choose from multiple possible addresses. It helps reduce errors and improve the accuracy of address data entry.

These concepts are not the be confused with address verification which is ensuring an address is connected to the individual who provided it. An address verification software can be useful in this case.

One disadvantage of address autocomplete is the potential for privacy concerns. Here’s how address autocomplete can be a privacy issue:

  1. To provide address autocomplete functionality, many applications and websites may collect and store user input data, including the addresses users are typing or selecting.
  2. Address autocomplete may also have location-based functionality, which means it may have access to a user’s real-time location. This can be concerning for users who are wary of sharing their location with applications or websites.
  3. Some

    address autocomplete services may share user data with third-party entities, which can raise additional privacy concerns if users are not aware of or have not consented to such data sharing.

GeoPostcodes databases are 100% GDPR compliant, to ensure your location data follows all data regulations in force.


We can help you with address autocomplete service.

Address autocomplete is a valuable tool that enhances the user experience and improves data accuracy. Its ability to simplify the address entry process makes it a widely adopted feature in many online applications and services using address forms.

Some of the main benefits are:

  • Efficiency: Address autocomplete speeds up the process of entering information in address forms or applications, reducing the likelihood of misspelling, which can lead to delivery issues and cost increases.
  • Data Quality: By suggesting a correct address in real-time, address autocomplete helps reduce errors and inaccuracies.
  • Increased Conversions: It enhances the user experience by simplifying the address entry process. A smooth and efficient address entry process will lead to higher completion rates.
  • Standardization: Address autocomplete often enforces standardized formatting and conventions, ensuring that addresses adhere to postal or mapping standards.

While both processes are important for address data collection, Address autocomplete and Address validation work on different stages of the data entry process:

  • Address autocomplete: Address autocomplete streamlines the data entry process by suggesting standardized format matches based on the address input of a user. While address autocomplete offers suggestions, it may not validate the accuracy of the entered address

  • Address validation: Address validation focuses on verifying and ensuring the accuracy and completeness of the address captured by the autocomplete form (among other sources). It confirms that the provided address exists in a valid postal or mapping database and adheres to formatting and standardization rules. It is crucial for preventing address-related errors, such as typos or incomplete addresses, that can lead to delivery problems, returned mail, or inaccurate location data.
