Carriers rarely kill a paid label on a fixed date, but the windows around refunds and voids are very real. USPS refunds an unused label only within 30 days of the print date, UPS processes no void after 180 days, and FedEx says a printed return label keeps working for as long as the account behind it stays in good standing. An old label may well still scan; it is the money and the paperwork that age out.
Each carrier publishes refund and void deadlines instead of a use-by date. The rules cited here were read on 2026-07-27.
Context for the expiry question: a current 1 lb box, 10 × 8 × 4 inches, quoted the day this page was written. When an old label’s status is murky, rebuying is often cheaper than the detective work.
| Carrier | Service | Price | Quoted window |
|---|---|---|---|
| USPS | Ground Advantage | $9.91 | 6-7 business days |
| UPS | Ground | $10.31 | 3-4 business days |
| USPS | Priority Mail | $14.49 | 4-5 business days |
| UPS | 3 Day Select | $15.13 | 3-4 business days |
| UPS | 2nd Day Air | $16.58 | 2-3 business days |
Rates also get refiled during the year, so a price locked months back stops matching what the same service costs today. That cuts both ways, and it is one more argument against sitting on labels you have already bought.
Per the refunds page at usps.com, checked 2026-07-27, a Click-N-Ship label the postage system has never scanned can be refunded within 30 days of its print date, and from 30 to 60 days the request goes through the Click-N-Ship help desk by email. USPS names no date after which an unused label stops being accepted, so the refund window is the deadline that actually bites.
Per ups.com, checked 2026-07-27, you can void a UPS shipment yourself within 90 days of creating the label, must ask UPS to do it between 90 and 180 days, and after 180 days a void will not be processed at all. UPS likewise stops short of naming a day the label itself dies.
The FedEx shipping FAQ at fedex.com, checked 2026-07-27, states that a print return label carries no expiration date while its account remains in good standing, and that an email return label can stay retrievable for up to two years from the request. Those statements cover return labels; for ordinary one-way labels we found no published window, so treat freshness as the safe default.
Often yes, since none of the three big carriers publishes a firm use-by date for a paid, unused label. You fall outside the USPS refund window after 30 days though, and outside every UPS void option after 180, so waiting quietly shrinks your fallbacks.
USPS allows it within 30 days of printing for labels that were never scanned, per usps.com. UPS voids run out at 180 days. On our side, the terms say unused labels may be eligible for carrier void or postage refund only when the selected carrier allows it, and carrier decisions take time.
Carriers pull the operative data from the barcode at the first scan, and none of the pages we checked ties acceptance to the printed date. Where the date really counts is refund math, which starts at label creation or printing.
Our terms cover that case head-on: we review the order and either issue the label, ask for corrected information, or refund the label payment when no label can be provided.
