Dear websites, please let me enter phone numbers, credit card numbers, bank account numbers, and similar, using any combination of spacing and hyphens I choose, please especially do this if the number is always displayed with the spacing included. It is a lot easier for me to enter the number, and check I’ve entered it correctly, if you let me do this. The code to strip any spaces out, if you can’t cope with them being there, is almost as simple as the code you must already have to detect they are there and complain about me using them - don’t make your users do it for you manually, it’s unhelpful, and kind of rude.
