A VAT number is (more or less) analogous to a sales tax number in the States (that have a sales tax). If you mean is there an equivalent to a calling-party-pays, premium-rate number, it is +1-900 or +1-area code-976 numbers. I am all but certain that zero businesses or spammers will call it even if you ask them and they’re virtually useless these days because VoIP and mobile carriers don’t generally support making calls to them. The only lines that still work for calling them are regular, regulated, post-paid billing POTS lines. Added: I also just looked and apparently both AT&T and Verizon no longer bill customers for premium-rate charges (pass-through billing) so there are even fewer lines that still support calling those numbers.
