ZIP Code Verification

ZIP code verification for better experiences and better data

A faster, easier way to verify zip codes and capture accurate address data in your forms and checkouts.

Enter up to 5 postcodes/addresses, per IP address per day, to see real-time address capture from Loqate in action. Don't forget, you can start at any point of the address.

ZIP code lookup and verification improves user experience and increases conversions

A smooth on-boarding process is crucial. ZIP code lookup and verification makes capturing a full address faster and more accurate than typing it manually. Getting customers through your checkout or registration process quicker and with less frustration reduces cart abandonment and drop offs.

Real-time address and ZIP code lookup

Find an address in as little as 3 keystrokes. As soon as a ZIP code, business name or street is typed, suggestions to auto-complete the address are immediately provided, with nearest locations coming up first.

The traditional ZIP code lookup needlessly adds extra steps to your checkout experience. ZIP codes can cover up to 100 addresses but using our type-ahead solution, you can get to a single delivery point much faster. With our fuzzy-matching capabilities, we correct abbreviations, misspellings and other errors to ensure the right address is captured every time.

The best possible data quality

ZIP code lookup and verification cuts back data entry errors at the point of capture by more than 20%. Checked against Royal Mail PAF^®, the most up-to-date ZIP Code Address File, you can be sure you are collecting correct address data at the point of entry. This reduces the need to clean data once it's in your database and its standardized format ensures accurate deliveries.

Reduce costs

Increase business efficiency by speeding up data entry, avoiding typos and the cost of failed deliveries. Remember, the real cost occurs when the delivery fails, causing redelivery charges, and an adverse effect on customer satisfaction, loyalty and future sales.

Better user experience

Auto-complete results appear as soon as you start typing a postal code, with the nearest locations coming up first.
By providing a quick way to enter address details you allow customers to move smoothly through the checkout and reduce form or cart abandonment. This all helps to improve the end-user experience and ultimately customer satisfaction and loyalty.

With Loqate you'll know where, better
