What number will h&m call with(orlando, FL)?

I did a online application a couple days ago and is currently waiting for a call back. I have so much advertisment and 800 numbers calling me, i am just curious what number will H&M call with. Will it be a local phone number(407)? Also if I do get a interview I understand I should send a thank you letter, where can i send this too? I dont think I would ask the person who interview me his/her adress or email looking like a creep and end up loosing my job opportunity lol. Thanks for reading guys :)
