How to address a certified mail envelope
Address the envelope normally, then place the certified mail label, PS Form 3800, above the delivery address or in the upper right area, leaving at least three and a half inches of clear space from the right edge for the postage meter. If you want a return receipt, PS Form 3811, the green card, goes on the back, with the recipient address on the front of the card and your return address on the back.

Certified mail does not change how you address the envelope. It adds to it: a tracking label that needs specific clearance from the postage meter, and optionally a return receipt card that needs its own placement on the back. Most of the confusion around certified mail is not about the address at all, it is about where these extra pieces go without interfering with each other or with the postage.
Get the placement wrong, label too close to the postage zone, and the consequence is not cosmetic. A meter that prints over the tracking barcode can genuinely delay delivery on a piece of mail specifically chosen because tracking and proof of delivery mattered enough to pay extra for.
Step by step
Address the envelope exactly as you normally would
Recipient name and address in the usual position, your return address in the top left. Certified mail does not change the basic address format at all.
Place the certified mail label with clearance from the postage area
PS Form 3800 goes above the delivery address or in the upper right, but it needs roughly three and a half inches of clear space from the right edge for the postage meter. If the label overlaps that zone, the meter can print over the barcode and delay delivery.

PS Form 3811, the green card, attaches to the back of the envelope. Write the recipient address on the front of the card and your own return address on the back, since that is where the signed card gets mailed back to.
Use restricted delivery if only one specific person should be able to sign
Restricted delivery requires the named recipient specifically, verified by photo ID, rather than anyone available at the address. It costs more and is used mainly for legal or sensitive notices where it matters who personally receives the piece.
Know what happens if the recipient refuses to sign
A refusal gets marked and the mail is returned to you, but the attempt itself is still documented. Refused certified mail is generally treated by courts as valid proof of attempted delivery, which is often the entire reason certified mail was used for a legal or formal notice in the first place.
Quick reference

| PS Form 3800 label | Above the address or upper right, 3.5 in clear from the right edge |
| PS Form 3811 green card | Back of the envelope, recipient address on front of card |
| Your return address for the green card | Back of the PS Form 3811 card itself |
Special cases
The rule above covers most people. Here is what changes for the rest.
What happens if the recipient refuses to sign for certified mail?
The carrier notes it as refused and the piece is returned to you. It is not illegal to refuse certified mail, and once refused it is no longer the recipient obligation. What matters for the sender is that a documented refusal still counts, in most legal contexts, as a valid attempt at delivery, which is frequently the whole reason certified mail was chosen for something like a legal notice or an eviction filing in the first place.
How long does USPS hold certified mail if nobody is available to sign?
Generally around 15 days at the local post office, after one or two delivery attempts and notices left at the address. If it remains unclaimed after that window, it is returned to the sender the same way a refused piece would be.
Does restricted delivery really require government ID?
Yes. Restricted delivery is specifically designed so only the named individual can sign for the piece, and the carrier verifies that with photo identification rather than accepting a signature from anyone else at the address, including a spouse or coworker who could sign for standard certified mail.
