邮政公布2026年假日寄件截止日：本土普通邮件最迟12月17日 特快专递12月19日
美国邮政署（USPS）已公布2026年假日季推荐寄件日期。要让邮件与包裹在12月25日圣诞节前送达，美国本土48州范围内的 USPS Ground Advantage 与一类邮件（First-Class Mail）最迟应在12月17日寄出，优先邮件（Priority Mail）为12月18日，优先特快专递（Priority Mail Express）为12月19日。
寄往 Alaska、Hawaii、波多黎各及美国属地的包裹，Ground Advantage 的建议截止日提前至12月16日，其余服务的日期与本土相同。邮政署同时指出，今年光明节（Hanukkah）在12月4日至12日，较往年为早，需要寄送该节日礼品的民众应相应提前安排。
寄往军事地址与国际地址的完整建议日期表，邮政署建议民众自10月中旬起在其假日寄件页面查询。邮政署表示，假日季业务量庞大，始终建议民众尽早寄出邮件与包裹。
上述日期为邮政署9月22日发布的官方推荐时间，属于「预期节前送达」的建议截止日而非保证。
USPS Announces 2026 Holiday Mailing Deadlines: December 17 for Ground and First-Class, December 19 for Express
The U.S. Postal Service has announced its recommended mailing and shipping dates for the 2026 holiday season. For expected delivery before December 25 within the contiguous United States, USPS Ground Advantage and First-Class Mail should be sent by December 17, Priority Mail by December 18, and Priority Mail Express by December 19.
For Alaska, Hawaii, Puerto Rico and U.S. territories, the recommended Ground Advantage date moves one day earlier, to December 16, while the other services keep the same dates. USPS also noted that Hanukkah falls earlier this year, from December 4 to 12, and advised customers to adjust their mailing plans accordingly.
A complete list of suggested dates for military and international addresses is available on the USPS holiday shipping page from mid-October. The Postal Service said customers should always plan to mail and ship early during the holiday season.
The dates, released by USPS on September 22, are recommended send-by dates for expected pre-Christmas delivery, not guarantees.
