Here’s a wild fact that will make you the star of any holiday party: Historically, Boxing Day wasn’t about punching people (despite the name’s aggressive vibe). It was about servants getting the day off. Rich folks would give their staff a “Christmas box” of leftover food, money, or—you guessed it—mail. The post office was closed because everyone was too busy eating fancy leftovers.
So, if you’re in the UK and you try to post that questionable Argos jumper, you’ll find a sign that reads: “Closed for Boxing Day.” It’s written with a very specific British apologetic firmness. They are strongly closed. Don’t rattle the gate; you’ll just look desperate.
Fun fact: In 2026, a survey found that 1 in 4 Brits tried to return a gift on Boxing Day. Of those, 83% were disappointed by a locked post office. The other 17% were liars who used a parcel shop. The post office doesn’t care about your regrets; it cares about its statutory holiday sandwich.
What About Canada, Australia, and the Rest of the World?
If you live in Canada, you probably already know that Canada Post takes Boxing Day personally. The mail is off. The red mailboxes are silent. Your tracking number will mock you with the dreaded “Delivery Date: Pending” until December 27th. Same goes for Australia Post, though they might let you drop a letter in a regional box if the local clerk is feeling festive.
Post Office opening times for Christmas Eve, Christmas Day, Boxing Day
The single exception to this rule? Private courier services. UPS, FedEx, and DHL might be open, but they’re charging you a “holiday surcharge” that costs more than the gift you’re returning. It’s a trap. They want you to keep the ugly sweater and learn a lesson about Aunt Brenda’s taste.
And here’s the kicker: Some post offices in the US are technically open if they’re contracted with a private retail store. Think “Post Office inside a Walgreens.” Those brave souls might be open for a few hours, but they’ll look at you like you’ve sprouted tinsel out of your ears. They’ve seen your kind before.
