Data processing

Postal check and correction

Is your post actually delivered? Incorrect postal addresses cause unnecessary costs and lead to delays, complaints and returns.

We tackle the problem at the root: For a postal check of your database, our independent partners check all addresses against a street directory containing more than 1.2 million street names and all 28,000 postcodes which is based on the original postcode data of Deutsche Post. Any wrong postcodes or typos in street names are corrected automatically enabling your mailings to be delivered without hindrance in future. In addition, performing a postal check followed by a merge purge will facilitate the elimination of as many duplicates as possible.

Get your database up to scratch by requesting a non-binding offer right away.
