Hi there, before I make further comments, could you confirm if I understood this correctly? <Durchwahl> would be the equivalent to English's phone number extension correct? (Eg. a company's landline with extensions to different people/extension)

Morning Euskirchener, thanks for your feedback!

I've went through the German's regulation on phone numbers, and this is indeed a caveat situation. German mobile numbers can have 3 or 4 digit prefix number (without the turntable 0). For example, the prefix could be 15xx, 16x, and or 17x.

If you look carefully at section 015 of the wikipedia page you've sent me, you'll see that it has being explained over there.

Please let me know if you have any other concern! ;)

Hi Herrieman,

Thanks for the FYI!

Yes, I am aware of the turnkable 0s in the area codes. I left it in because I will be running a script in a while that would be sanitizing all POI's phone numbers in one go (adding the country code, truncating the leading 0s, validating the phone numbers etc.).

This is actually how I managed to pin point all of the invalid phone numbers in the first place. ;)

Understood, so just for my future reference, a POI node (say a restaurant) and an address node should be just merged into one node then?

I suspect that the data source does not have the up-to-date date in regards to Hoogstraat. I can confirm that the street name is Hoogstraatje
