Address validation: Verify addresses quickly, easily and at unbeatable conditions!

The Adresslabor offers you up-to-date data maintenance with the help of modern tools. Correct and clean up your customer directory by checking addresses, e-mails and telephone numbers!

Incorrect entries in your existing customer data may seem inconspicuous at first - but they often have noticeable negative effects. Incorrect data records often result in considerable administrative effort. Through consistent data maintenance, you can minimise the potential economic damage.

Data cleansing through address validation and further steps

Use us for data cleansing of your customer entries. We quickly and reliably correct any errors. Avoid duplicates, i.e. double entries that differ only in a typo or number error. After all, you want to prevent your mail from reaching the customer in duplicate because of such an entry.

For this purpose, we carry out address validation, for example. In addition, our portfolio also includes:

• eMail check
• Telephone number check
• Name check.

eMail address in the database maintenance check

In the digital age, email is increasingly becoming the communication channel of choice when it comes to providing your customers with information. If a visitor to your website enters his address incorrectly during registration, he will not receive any of your messages; in the worst case, the entire registration process will fail because the confirmation e-mail will not arrive. With our e-mail address check, common incorrect entries are detected directly so that the system can correct them immediately or display an error message to the visitor.

In addition to checking email addresses, our database maintenance service also includes the analysis of telephone data. Through automated test calls, you can thus determine which numbers are outdated and therefore no longer in service. In addition, we find missing customer telephone numbers for you or determine the corresponding addresses on the basis of telephone data.

Postal address validation: address update and address cleansing

By running a postal address check on your database, you ensure that your letters, flyers and other correspondence actually reach the person they are intended for.Our address update automatically corrects numerous typical input errors, such as abbreviated street names or transposed digits in the postcode. In addition, address cleansing helps to filter out entries that are not meant seriously, for example "sample city" or "test street". This ensures that you do not incur unnecessary packaging and postage costs for items sent to fantasy addresses.

You can use our various offers for data maintenance in different forms: as individual tests, as mass checks or in the form of API interfaces for the input mask of your registration form. Would you like to see the process of our validations in an example?
