To add to this, the 800 part is effectively an international convention for toll free numbers at this point. Most countries use either “800”, “0800”, or “1800”. On top of that the +800 country code is used for international toll-free numbers, but AFAIK it only works in a few countries.
To add further more: often also 810 or 820 numbers exist, where a phone call might have a toll up to 10 or 20 cents per minute respectively. With 900 numbers you usually dont know, how expensive they are, when only looking at the number.
