How to Find a Pen Pal as an Adult (And What to Write)

Part of the Ultimate Guide to Pen Pals

You want a pen pal. You’ve wanted one for a while, but every time the thought crosses your mind, a little voice says, “Isn’t that something only twelve-year-olds do?”

It’s not!

Grown adults are quietly driving a pen pal comeback big enough that The Boston Globe covered it in May 2026 and Pinterest named “penpal ideas” one of its 2026 trends, with searches up about 90 percent. Regular people, wanting a reason to check the mailbox.

Where do you find a pen pal?

The fastest routes: join a pen pal club, set up a profile on a matching site like Global Penfriends, mail a single postcard through Postcrossing to test the waters, post an introduction on Reddit’s r/penpals, or start close to home at your library. All of these work; they differ in how fast they move and how much browsing you do.

We catalog them by hand in one place. Browse the Pen Pal Directory and see who’s out there.

Pen pal clubs. Organized communities built for trading letters. Some match you with one person, some run group swaps, some are simply a well-tended list of people who want mail. They’re the easiest way in, because someone else has already done the work of building the community. Our Ultimate Guide to Pen Pals lays out every kind, and which fits which person.

Hand-matched clubs. A newer breed skips the browsing entirely: you fill out a short survey, and a real human pairs you up. The Dirt Pen Pal Club, run by The Dirt at UC Davis, pairs readers each season for free, and the Maclean Smyth Snail Mail Club runs a free once-a-year match. Getting matched by a person feels less like shopping and more like being set up by a friend. (Clubs, societies, exchanges, matchmakers: the different kinds of pen pal clubs maps them all.)

Online matching sites. Global Penfriends has been matching pen pals by post and online for over twenty-five years, welcomes all ages, and is free to join. Pen Pal World is free with a premium tier. InterPals costs nothing either, though longtime users report thin moderation there, so browse with a skeptical eye and keep your home address to yourself. Before you spring for any paid tier, our breakdown of free vs. paid pen pal sites explains what paying buys. And if you’re hoping for a pen pal abroad, our international pen pals guide covers postage, customs, and writing across cultures.

Postcrossing. Postcrossing works differently: you mail a postcard to a random member, and once it arrives, a different member mails one to you. More than 800,000 members trade postcards this way. It won’t hand you an ongoing pen pal, but as a first taste of snail mail it’s unbeatable. Signing up is free; your only cost is postcards and postage.

The Slowly app. Slowly brings the pen pal experience to your phone, with letters that arrive at a real-mail pace instead of instantly. The core app is free.

Reddit and Facebook groups. Reddit’s r/penpals is one of the most active pen pal spaces online. People post short bios and what they’re looking for, and you reply to someone who sounds like a match. On Facebook, Worldwide Snail Mail Pen Pals and Bring Back Paper (run by The Reading Residence) both host free, ongoing pen pal exchanges.

Instagram and TikTok. Search #penpal, #snailmail, or #happymail and you’ll find a whole world of people who love writing letters, many of them looking for new pen pals right now. Comment on posts, reply to stories, send the shy DM: “I’d love to be pen pals if you’re open to it.”

Local options. Check your library’s community board; some libraries run their own pen pal programs and even handle the mailing. Senior centers often have residents who would love a pen pal, some schools run intergenerational programs, and craft or journaling meetups are full of people who already love paper and ink. Letter-swap events, where everyone writes to everyone, let you try the hobby before committing to one person.

Kindness letters. A different thing from pen pals, and worth knowing about: instead of trading letters, you give one. Programs like Letters Against Isolation and The World Needs More Love Letters deliver your card to an isolated senior or to somebody going through something hard, no reply expected. We catalog around 60 of these programs in the Kindness Letter Directory.

How do you choose the right pen pal?

Pick someone who seems interesting and willing to write back; you are not choosing a soul mate. Agree on pace before the first letter, start with one pen pal instead of five, and protect your home address until trust builds. Everything else sorts itself out letter by letter.

Shared interests help, but different perspectives are just as good. A pen pal who loves what you love makes for easy conversation. A pen pal who lives a completely different life makes for fascinating conversation. Both work.

Agree on frequency up front. Some people want to write every week, some once a month, and neither is wrong. Mismatched expectations are what lead to guilt and ghosting. A quick “I’m a once-a-month writer, is that okay?” saves a lot of stress later.

Start with one. It’s tempting to sign up for five pen pals at once. Don’t. Get into a rhythm with one person first; add more later if you want to.

Sort the safety basics first. Use a PO box or a mail-forwarding service instead of your home address, at least at first. A small PO box starts around $15 to $25 per three-month term in most areas, and virtual mailbox services start around $5 to $10 a month (prices checked July 2026; both vary by ZIP). Beyond that, trust your instincts. You don’t owe anyone your personal information because you exchanged a letter. Our pen pal safety guide walks through the rest.

What should you write in your first pen pal letter?

Introduce yourself with the details that make you specific, say honestly why you wanted a pen pal, share a slice of your life, and ask a few real questions. A sticker or a tea bag tucked into the envelope sets a generous tone, never a requirement.

The first letter is the hardest one. After that, it’s a conversation.

Introduce yourself, but make it interesting. Skip the résumé format. “I’m Sarah, 34, accountant” is fine but forgettable. “I’m Sarah, I live in a tiny apartment with a cat who judges me, and I recently became obsessed with making my own pasta” is someone a person wants to write back to. Nobody connects over “I enjoy traveling.” People connect over “I once drove four hours to try a specific donut.”

Say why you wanted a pen pal. Be honest. “I’ve been craving slower, more intentional connections” or “I’ve always loved getting mail and finally decided to do something about it.” A little vulnerability in the first letter sets the tone for the whole friendship.

Ask specific, curious questions. “What’s the best meal you’ve cooked recently?” or “What’s a hobby you’ve been meaning to start?” Good questions make it easy for them to write back.

If the blank page freezes you, steal this template. It works in an envelope or in a matching site’s first message box. Swap the brackets for your own details:

Hi, I’m [your name], and this is my first pen pal letter since I was about ten, so bear with me. By day I [teach seventh graders / chase a toddler / wrangle spreadsheets], and lately I can’t stop [baking bread that refuses to rise / rewatching old mystery shows]. I wanted a pen pal because I miss conversations that take their time. Tell me the best thing that happened to you this month, big or small, and I’ll trade you mine in my next letter.

When you want more than a framework, our guide to what to write to a pen pal digs into the blank-page problem, and how to write a letter worth writing back to is about earning the reply.

What do you write after the first letter?

Respond to what they wrote, then add something new. Answer their questions, react to their stories, share an update from your own life, and ask a few fresh ones. That’s the whole rhythm, back and forth, letter after letter.

Don’t stress about matching their length. If they wrote three pages and you wrote one, that’s fine; the content matters more than the word count.

And if it’s been a while since your last letter, skip the six sentences of apology. “It’s been a minute, but I’m here now” is all the transition you need.

Our guide to keeping a pen pal friendship going is for the long haul: pacing, ruts, and what to do when they go quiet. For the craft of the letters themselves, there’s the Ultimate Guide to Writing a Letter.

Opening lines for pen pal letters

For the very first letter:

• I’ve been wanting to do this for a while, so here goes: hi, I’m your new pen pal.
• This is my first pen pal letter as an adult, so if it’s a little awkward, that’s why.
• I saw your post and thought, “Yep, that’s my person.” And here I am.

For follow-up letters:

• Your last letter made me smile for a full five minutes. Consider this my attempt to return the favor.
• I’ve been carrying your letter around in my bag all week because I keep rereading it.
• Three things happened since I last wrote, and I saved them all for you.

For when it’s been a while:

• It’s been way too long, and I’m not going to waste time apologizing. Let’s just pick up where we left off.
• Life got busy, but I never stopped thinking about writing you.
• I owe you a letter, so this one comes with interest.

What are the unwritten rules of pen pal etiquette?

Reply in a reasonable time, don’t ghost without a note, respect a pen pal who wants to keep the friendship on paper, and end a mismatch kindly. Extras like stickers and washi tape are welcome and never expected. That’s most of the rulebook.

Don’t ghost without warning. If you need a break from writing, say so. A quick “I’m taking some time off, but I’ll be back” beats silence, because silence leaves your pen pal worrying about you.

Don’t keep score on response times. Life happens. A reply can take two weeks or two months, and it doesn’t mean they stopped caring. Give grace and expect it in return.

If the match isn’t working, let it go gently. Some matches don’t click, and that’s normal. You can let a correspondence fade, or be honest: “I think we might not be the best match, but I’m really glad we connected.”

The full pen pal etiquette guide has the rest: gifts, boundaries, and the golden rule.

What makes pen pal friendships different?

A pen pal is the antidote to a very modern kind of loneliness, not because letters are magical.

Because letters are slow.

You can’t fire off a quick reply. You sit with what someone said, think about it, and answer with intention, with no algorithm deciding who sees it and no audience to perform for. It gives you the depth of a close friendship without the pressure of real-time conversation. You can take a week to answer. You can think before you speak.

People share differently on paper, too. More honestly. You don’t edit a letter the way you edit a text; you just write, and the performance falls away somewhere between the greeting and the signature.

And then there’s the anticipation. Waiting for a letter is a joy the instant-everything world has almost forgotten, and finding a handwritten envelope with your name on it never gets old, not after the hundredth letter.

Common worries (and honest answers)

“I’m too old for a pen pal.” Adults are the heart of this hobby. Spend five minutes on r/penpals or in any pen pal club and you’ll find teachers, nurses, engineers, and grandparents, all looking for the same thing you are. There is no age limit on wanting real, human connection.

“What if we run out of things to say?” You won’t, and if you ever feel stuck, our 50 letter writing prompts exist for exactly that moment.

“What if they stop writing?” It happens, and it’s okay. Some pen pal relationships last years. Some last three letters. Both were worth having. If one fades, find another.

“Is it safe?” Yes, with basic caution. Use a PO box, hold back your last name and home address until you feel comfortable, and trust your gut. The vast majority of pen pal experiences are wonderful.

“What if I’m boring?” You’re not, and your pen pal is worried about the exact same thing. The grocery run, the neighbor feud, the soup that didn’t work out: all of it is fascinating to someone living a completely different life. Share the small stuff. That’s the good stuff.

Write the first letter

Every pen pal friendship starts the same way: one stranger decides to write first.

Be that person.

Pick your route in the Pen Pal Directory, write a letter that’s imperfect and honest, and drop it in the mail. You don’t need beautiful handwriting or special paper, just a stamp. And if you’d rather be pointed somewhere, the Find My Club quiz takes about a minute.

Then check your mailbox in a week or two, and see what comes back.

You might be surprised how much a stranger’s handwriting can feel like home.
