What Is a Pen Pal? Meaning, History and the Kinds of Pen Pals Today

The short answer: a pen pal is someone you write to regularly, usually a person far away whom you haven't met. Traditionally pen pals swapped handwritten letters by post. Today a pen pal can also be someone you email, send postcards to, or write to in an app. What makes them a pen pal is the regular writing and the friendship that grows from it.

Pen pal meaning

The word is simple: pen for writing, pal for friend. A pen pal is a friend you know through writing.

Dictionary.com gives two definitions:

• American: a person with whom you keep up an exchange of letters, usually someone so far away that meeting in person is unlikely.
• British: a person you regularly exchange letters with, often in another country, whom you haven't met. It lists pen friend as another name.

It describes "pen pal" as an Americanism from 1935-40. You'll also see it written as penpal or pen-pal, and in Britain penfriend is common. Wikipedia notes that pen pals are usually strangers whose relationship rests mostly or only on their letters, and that the friendships are usually built on cultural exchange and friendship.

What pen pals actually do

A pen pal friendship is slower and more thoughtful than most chat. People usually write about:

• Daily life: their town, their job or studies, the weather, what they ate.
• Culture: holidays, food, music, how things are done where they live.
• Interests: books, films, hobbies, a language they're learning.
• Bigger thoughts, once they know each other: plans, worries, what matters to them.

Each letter answers the last one and asks something new. Over months, that turns two strangers into friends. If you need ideas, see our list of pen pal questions.

A short history

Writing to someone far away is as old as letters, but organised pen pal friendships grew in the 20th century, often through newspaper and magazine columns.

• Newspaper pen pal columns. The Christian Science Monitor, for example, ran its own pen-pal program from 1928 to 1969, and many readers found pen pals through it.
• The word itself appears in the 1930s, according to Dictionary.com, with "pen friend" used alongside it.
• Key pals. When email arrived, "key pals" (keyboard pals) carried the idea online, faster and without stamps.
• Websites and apps. Pen pal directories, postcard exchanges and letter apps now let adults find a pen pal in minutes rather than waiting for a newspaper column.

Why people have pen pals

• Friendship. Someone who knows you through your words, often more honestly than people who see you every day.
• Learning about the world. Real daily life in another country, not the tourist version.
• Language practice. Writing to a native speaker is steady, low-pressure practice.
• Something to look forward to. A reply in the post or in your inbox is a small bright spot in the week.
• Writing for its own sake. Many people simply enjoy putting thoughts on paper.

Some pen pals eventually meet. Many never do and still stay friends for years.

How to get a pen pal

In short:

1. Choose your pace: paper, slow letters or chat.
2. Pick one or two places that match it.
3. Write a short, specific profile with no private details.
4. Send several first messages yourself, each ending with one real question.
5. Agree a rhythm, and keep answering.

Pen pal safety for adults

• Keep your home address private until you know someone well, unless you're on a postcard service built to share addresses.
• Never send money or gift cards, whatever the story.
• Watch for fast romance. Declarations of love, a sad story and then a request for help is a common scam pattern.
• Block and report anyone who turns a friendly exchange sexual or pushy.

The short version

A pen pal is a friend you write to. It used to mean letters in the post; now it can be postcards, email, slow-letter apps or instant chat. The format matters less than the habit: write regularly, answer what they said, ask something real, and let the friendship grow one letter at a time.
