Our services at a glance

Address verification

The address check validates the complete address, verifies the spelling and adds any missing data. If the address is not unique, correct alternative suggestions are displayed.

For many countries, the addresses are guide-codable as with DHL in Germany, i.e. subsequent guide-coding by DHL, which is subject to a charge, is not necessary.

Input assistant for addresses

Typing errors, which occur particularly often on smartphones and tablets, can be reduced simply and effectively by suggesting addresses when entering them. Your users receive these after entering the first few digits and can easily choose from the correctly spelled suggestions. This works nationwide and internationally for almost all countries.

E-mail check

The e-mail validation validates e-mail addresses according to various criteria:

  • Format
  • valid country domain
  • Availability of the e-mail server
  • Validity of the e-mail address
  • E-mail account feedback (full, blocked, outdated.)

This way, your customers can be informed as soon as they enter the email that there is a spelling mistake, or the email may not be delivered because the roof of the post office is full.

Salutation and first name check

We match every first name entered with a database of over 30,000 first names. If first names are uniquely assigned to one gender, we can display a note when choosing the salutation if the chosen salutation is incorrect.

Telephone number check

The phone number formatting recognizes area codes in Germany and standardizes them according to a predefined standard. This can be freely defined by you. This works for German landline numbers as well as for mobile numbers.
