Poste restante should solve your problems.Here is info.You want to make sure it goes to Vasser St.branch if mailing to Reno.
In the United States, the U.S. Postal Service uses the term “general delivery” and reserves the term “poste restante” for international mail sent to general delivery. Mail is addressed as follows:
For example Mrs. Jane Q. Smith GENERAL DELIVERY Washington, DC 20090-9999
In the ZIP+4 code, the +4 code for general delivery is 9999. The main post office in a community will hold such mail for up to 30 days. According to the USPS website, "In medium to large cities with multiple ZIP Codes, you’ll want to make sure senders use the ZIP Code for the area’s main Post Office."
