hcard - hcard format for company address type

Question

I'm looking for best way to use hCard format on my site and my concern is about type of company address

My contacts data goes like this:

CompanyX Office 28 Nulla St. Mankato Mississippi 96522

---

CompanyX Headquarters 92 Dictum Av. San Antonio MI 47096

---

CompanyX Customer Service 48 Dolor. Av. Muskegon KY 12482

My vcard html goes like this:

<div class="vcard">
<strong class="org">CompanyX <span class="category">Office</span></strong>
<div class="adr">
    <div class="street-address">28 Nulla St.</div>
    <span class="postal-code">96522</span> <span class="locality">Mankato Mississippi</span>
</div>
