How to address the envelope
Use the address letter for letter
The front of the envelope carries 650 California St, 12th Floor, San Francisco, CA 94108 and nothing else in the address block. Check the 94108 digit by digit before it goes in the post.
Add your return address
Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.
Send it certified
Certified, not courier: buy it at the counter, keep the postmarked slip, and the letter to San Francisco is traceable from the article number until it is signed for.
Keep the records
Hold on to the letter copy, the receipt and the tracking page.
