Where should I mail my H4 EAD application if my spouse's most recent I-797 begins with WAC

I’m really confused as to where I should be mailing my H4 EAD visa application.

I’m the H-4 spouse of an H-1B nonimmigrant, and the receipt number of my spouse’s most recent Form I-797 Notice of Approval for Form I-129 begins with WAC

Are the mailing addresses different from the service centers? For WAC service center is SFO - but application is expected to be mailed to Phoenix, AZ 85034? Please clarify

Thanks!

Yes, different offices may process different types of applications.
