US toll free number free from UK?

Hi all - hope all Reading this are doing good

My question is :
Are US toll free numbers free to call from UK landline?

I got a specific number to call A holiday resort company that’s in ORLANDO;

0014077223575

Or another but without the 00s

18888859533

Any help shall be appreciated

** the company themselves said that the number is toll free and is free to call from wherever in the world**

?
