By simplifying address validation at point of entry or in batch, you can:

  • Improve Deliverability
  • Reduce Costly Errors
  • Boost Address Data Accuracy
  • Increase Delivery Speed
  • Boost ROI
Approximately 20% of postal addresses entered online contain errors - spelling mistakes, wrong house numbers, incorrect postal codes, formatting errors that don’t comply with a country’s postal regulations. This can result in late or undeliverable shipments, a big and costly concern for companies doing business domestically and across the globe.

Melissa’s Global Address Verification and Validation service verifies addresses for 240+ countries and territories at the point of entry and in batch to ensure only valid billing and shipping addresses are captured and used in your systems.

  • Leverage a postal certified address engine using official government data including CASS (USPS), SERP (Canada Post), PAF (Royal Mail) and more
  • Correct & verify international addresses by adding missing components such as postal codes, locality, and more
  • Standardize/normalize addresses to meet local in-country formatting rules
  • Transliterate to and from native country languages and Latin
  • Add precise lat/long coordinates up to the rooftop (delivery point) level
With the help of Melissa’s solutions, we have been able to realize a customer onboarding process which makes registration faster and simpler – and reduced manual validation costs.Elisabeth Ihmels @ car2go

Frequently Asked Questions

Yes, Melissa's address verification solutions allow you to verify postal addresses from 240+ countries. Our tool will parse, standardize, and verify addresses before they’re entered into your database, so you never have to worry about bad data in your system. Plus, Melissa can transliterate addresses from multiple language scripts to create validated output in Latin characters.

Some online services don’t have access to official government data for address verification. Melissa relies on CASS (USPS), SERP (Canada Post), PAF (Royal Mail), and other postal-certified data to update and correct records.

Whether you do business in the U.S. or abroad, you need accurate address information to reach your customers. An address verification service checks all your customer records to ensure they are correct and complete, improving data quality and saving your business time and money.

Address verification services offer many advantages, including:

  • Better customer experience: If you have incorrect addresses, you’re losing out on opportunities to communicate with your customers and build loyalty to your brand.
  • Less returned mail: If you ship an item to an incorrect address, you’ll waste time and effort correcting the error, and you risk losing a customer.
  • Lower administrative burden: Manually correcting customer records is time-consuming. An address validation service ensures that a mailing address is correct the first time it’s entered into your database.
  • Cost savings: If you have complete address information, such as ZIP+4 for USPS mail, you may be able to save money on bulk mailings.

Validation is the process of confirming that a specific address exists. Verification goes an extra step: it compares an address against trusted reference data to confirm that mail can be delivered to the address. The verification process can also make corrections to the address and standardize the format. Melissa Data’s solutions provide both address validation and verification.

Address verification tools are software solutions that businesses use to check, correct, and standardize the format of a set of mailing addresses. Companies use these tools to verify their customer records.

Melissa’s global address verification service allows you to verify and correct addresses from over 240 countries around the world, using one single, user-friendly interface. For pricing information or to request a demo of our address verification software, contact us today.
