PTchan is a Portuguese bulletin board that was founded on December 16, 2010, then changed domains on July 19, 2018. However, there really isn't much to say about it, since the administration has mostly been anonymous, and it doesn't have much of a history.

The website started out at the “ptchan.net” domain, running Kusaba X, on December 16, 2010. There was the usual server issues,¹⁾ then PTchan made the switch to Vichan on August 11, 2016.²⁾ Due to the usual billing issues, this iteration lasted until July 19, 2018 as the data was destroyed, and their administrator decided it was time to pass ownership onto somebody else since they no longer had the time to manage it.³⁾

Around August 2018, the website was revived at the “ptchan.org” domain, running Vichan, then switched to a Vichan fork called NPFchan. On May 1, 2021, the website switched over to jschan, eventually forking it into ptchina by 2024. The layout was redone in February 2025, then PTchan began restructuring on April 23, 2025, so board creation was closed and the number of boards was reduced to five.

• The first incarnation of PTchan was represented with the Order of Christ Cross symbol.
• PTchan's mascot is 'Maria Marta Cunhel Guloso' (マリア・マルタ・クウネル・グロソ)⁴⁾ from Kūneru Maruta, which is a slice-of-life, cooking manga, published weekly in Big Comic Spirits.
• At one point, the 'PTchan.org' domain was presumably owned by a Brazilian, given its 55chan theme,⁵⁾ but they died while 'PTchan.net' emerged and the domain was eventually released in 2015.
• When you disable 'local time' in settings, PTchan generally follows the time in Continental Portugal and Madeira, which would be UTC±0 (without DST) and UTC+1 (with DST).
