Four things happen before a sold phone goes in the box
The box and the postage are the easy part. What actually goes wrong with a mailed phone is a buyer who cannot get past the lock screen, because the seller wiped the storage but left an account signed in. Below is the order that avoids it, then the packing and the carrier side of the job.

Erase, then box
Everything below happens before the tape goes on, not after.
The order that matters
Do these in sequence. Reversing the first two is the single most common reason a buyer messages back within a day of delivery.
- Sign out of the account before you reset it. On an iPhone that means Settings, your name, Sign Out, which turns off Find My and Activation Lock. On Android it means removing the Google account under Settings so Factory Reset Protection does not re-lock the phone to you after the reset. Do this step first; a factory reset performed first can leave the lock active with nothing left to sign out of.
- Factory reset the device. Erase all content and settings, or the equivalent under Android's system reset menu. This is what removes your photos, messages and app data, and it only sticks once the account above is already gone.
- Pull the SIM and any memory card. A SIM tray needs a pin or a paperclip; do it before the phone is buried in bubble wrap. Neither belongs in a mailed phone regardless of the buyer.
- Power the phone all the way off. Not sleep, not airplane mode — off. A phone that wakes up in a mail tray can search for a signal for the whole trip and land dead.
A live quote: Google Pixel 8 in original box
Captured 2026-08-22 through the SMKlog calculator: “Google Pixel 8 in original box”, Berkeley Heights, NJ 07922 to Austin, TX 78701.
Route
Berkeley Heights, NJ
to Austin, TX
Declared as
New in original box, battery installed
That declaration is why air tiers came back at all
| Carrier | Service | Price | Transit |
|---|---|---|---|
| USPS | Ground Advantage | $10.29 | 2-3 business days |
| UPS | Ground | $12.40 | 4-5 business days |
| UPS | 3 Day Select | $16.20 | 3-4 business days |
| UPS | 2nd Day Air | $16.25 | 2-3 business days |
| USPS | Priority Mail | $16.35 | 2-3 business days |
Every row shown is what checkout collects, carrier cost and SMKlog's charge together. USPS Ground Advantage won this lane at $10.29; a shorter route than New Jersey to Texas would likely come in under that. The bottom two rows are air services, and they are on this table only because the handset was declared new in its retail box. Sell a phone you carried for two years and those two rows come off, for the reason below.
Packing and the carrier side
Box it small and rigid
A phone-sized carton with bubble wrap around the handset beats a padded mailer for anything you would mind losing. If the retail box is intact, seal it and set it inside the outer box — buyers pay more for that box, and it keeps the screen from resting against packing paper.
Condition picks the tier, not the battery
USPS Publication 52's domestic lithium instruction reads that a battery installed in the equipment it operates is mailable “via air or surface transportation.” The narrowing comes one sentence later: a used, damaged or defective device holding that battery moves by surface transportation only. A resold handset is a used device, so the air tiers are closed to it and the outer box has to carry the surface-only wording. Read from pe.usps.com 2026-08-22.
Say what condition it is in
A used phone in working order is one thing; a phone with a swollen, cracked or recalled battery is a different shipment that most services will not carry at all. Describe it honestly at checkout and the right service tier follows automatically.
Picking between USPS, UPS and FedEx for this exact box is a route-by-route question — see how each treats a phone specifically on the USPS page and the FedEx page. Sending one out of the country adds a rule that catches a lot of sellers off guard; that is covered separately on the international page.
Where these rules come from
- USPS, Publication 52, Packaging Instruction 9D — the air-or-surface permission for an installed battery and the surface-only path for a used, damaged or defective device. Read 2026-08-22.
- Prices: our own capture against production for the Pixel 8 parcel above, Berkeley Heights, NJ 07922 to Austin, TX 78701, run 2026-08-22. Not list prices and not estimates.
USPS revises Publication 52 without notice, and UPS and FedEx set their own lithium limits separately. Treat the wording above as what each source published on the date shown.
Common questions
Do I have to factory reset a phone before shipping it?
Yes, if it is leaving your hands for good. Sign out of the cloud account first, turn off the anti-theft lock, then erase the device. Doing it in that order is what stops a buyer from opening a phone that is still tied to your account.
What is FRP lock and why does it block a resold phone?
Factory Reset Protection is Android's version of the same idea as Find My: the phone remembers the last Google account and refuses to finish setup for anyone else until that account signs back in. A factory reset does not clear it by itself. Remove the Google account under Settings before you reset, not after.
Should the SIM and memory card stay in the phone?
No. A SIM card carries your number and can be reused or cloned; a memory card carries whatever you never got around to deleting. Both come out before the phone goes in the box, regardless of who is receiving it.
Does the phone need to be powered off in the box?
Yes. A phone that wakes up mid-transit can key onto a network, buzz against the packing material, and drain the very battery a carrier is trusting to stay inert. Power down fully rather than leaving it asleep.
Can any carrier ship a phone with the battery installed?
Yes, with a condition test attached. USPS Publication 52 allows a lithium battery installed in the equipment it operates by air or surface transportation, so a sealed new handset can take any tier. A used, damaged or defective device carrying the same battery is surface only, and its box needs the words Restricted Electronic Device and Surface Transportation Only. A swollen or punctured cell is not mailable at any tier.
What box should a phone ship in?
A small rigid box, not a padded mailer alone. Wrap the phone in bubble wrap, seat it so it cannot shift, and if the retail box survived, put that sealed box inside the outer one — it protects the screen and it is worth money to a buyer.
