Why Magento 2 Webshops Benefit from Real-Time Address Validation

Magento 2 provides a default address input where customers can type each field freely. That inevitably leads to errors: spelling mistakes in street names, wrong postal codes, missing house number additions. Real-time address validation solves this.

The Problem: Incorrect Addresses at Checkout

With free text input for addresses, all sorts of things go wrong:

• Spelling mistakes — Linneausstraat instead of Linnaeusstraat
• Wrong postal code — customer types 1092 XC instead of 1092 CX
• Missing addition — apartment A gets forgotten

The result: the carrier does not know what to do, the package is returned, and you pay double shipping costs.

Why Real-Time Address Validation Is Essential in Magento 2

With the ApiCheck extension for Magento 2, the customer only fills in the postal code and house number. Street and city appear automatically.

Example:

• Customer types: 1092CX + 12
• Street name: Linnaeusstraat
• City: Amsterdam

The customer sees the address immediately. Is it wrong? Then they adjust the postal code or house number and immediately get a new result.

Did You Know...

An incorrect delivery address costs you an average of €7 to €15 in extra work:

• Contacting the customer
• Repacking and resending
• Administrative handling of the return

Ten errors per month = at least €70 per month in losses.

How Real-Time Address Validation Saves Time

Without address validation, your logistics team only notices errors after the order has been placed — when the package has already been prepared. With real-time validation, you intercept the error in the form, before the order enters the system.

That saves not only shipping costs, but also customer service time and frustration on both sides.
