bpost (Belgian Post Group) provides an API to validate belgian address : https://www.bpost.be/site/en/webservice-address.

The goal of the "bpost Batch Address Validation" tool is to validate a huge amount of addresses by querying the bpost API.

The tool only requires PHP 7.0+.

git clone https://github.com/geo6/bpost-batch-validation cd bpost-batch-validation/ # Install Composer curl -sS https://getcomposer.org/installer | php # Install dependencies php composer.phar install 

To process the data/test.csv, run :

php validate.php --file=data/test.csv 

If you want to skip some records, you can add --start option :

php validate.php --file=data/test.csv --start=2 

Your file must be a valid CSV (Comma-separated values) file.
The structure is the following :

• Identifier (string or integer)
• House number (string or integer)
• Streetname (string)
• Postal code (integer)
• Municipality name (string)

Have a look at data/test.csv if necessary.
