PenPal World is probably the biggest penpal finding site on the web.

Currently they have over 400,000 members from every country in the world. You can search for penpals before signing up by using the ‘Search Members’ tab on the main page (although you need to sign up to make contact).

• Penpals: 400,000 +
• Activity: Very active. 500+ new members signed up yesterday
• Hidden email address: Yes
• Internal messaging: Yes
• Profile pictures: Yes (1 photo)
• Block penpals from contacting you: Yes
• Ability to hide/pause account: Yes

Pros: One of the things I really like about PenPal World is how fast it is. 8 different search methods makes it relatively easy to find the penpal you are looking for.

Cons: You have to pay (yes dollars) to send more than 5 messages a day.
