You must mail Form 8802, including the full user‑fee payment, at least 45 days before the date you need Form 6166.
Enter your residential address on line 2 and a separate mailing address on line 3a if you want correspondence sent elsewhere.

Attach any required employee‑benefit‑plan filings (Form 5500 or determination letter) or DRE statements, then sign the form under penalties of perjury before mailing it with the user fee.
If you enter a P.O. box or C/O address, certification may be denied, and missing required plan documents can also cause denial.
