Postal Services in Penang

A letterbox in Penang (18 January, 2013)

On this page about the postal services in Penang, we will get to know the post offices, mailings in Malaysia, postage, post boxes and letter boxes. I hope the information I have assembled will be useful to you.

Post Offices in Penang

Post Offices can be found throughout Penang Island. For more details, I have a page for it, Post Offices in Penang.


Every household is expected to have a letterbox for the delivery of mails by the postman. Most of these are square boxes with a lip for the insertion of the mails, with the address often written on the box itself. There is no specific colour to letterboxes, though most people use red.

Mailings in Malaysia

When sending a letter, take note of the classification of mails by Pos Malaysia, implemented since 1 January, 2006.

Standard Mail are letters that weigh a maximum of 50 gms, having a height of 90 mm to 165 mm and the width of 140 mm to 250 mm. The width has to be equal or more than the height. The maximum thickness of the envelope should be between 0.25 mm to 6 mm. White envelopes are preferred although soft colours are allowed. You should avoid using staples or metal clips for your letters. Finally, a 15mm space at the base of the envelope should be left blank for the printing of bar codes.


Latest details of postage can be found on the Pos Malaysia website. This information below was last updated on 20 July, 2015.
