Donate stamps to population matters

You can now donate your used stamps to Population Matters! We accept any stamps: new or used, marked or unmarked. Any and all UK and overseas stamps are accepted.

Step 1: Please carefully cut or tear about a centimetre border around any stamp that you are sending in. There is no need to remove the stamp from the part of envelope it is attached to.

Step 2: Please then pop your collected stamps in a standard-sized envelope, weighing no more than 100g and no thicker than 5mm, and post them to us at:

Population Matters

The Chandlery

50 Westminster Bridge Road

London SE1 7QY.

Please send in no more stamps than fit in a standard size letter / C5 sized envelope. To make sure that the stamps reach us and do not incur additional charges please do not overfill any envelopes ensuring that the stamps fit in a standard size and not ‘large letter’ as per Royal Mail guidelines and that the envelope is less than 5mm thick.

If you have any questions please email supporters@populationmatters.org.

We will collect your stamps together and, when the collection reaches a certain weight, we recycle the stamps. For every kilogram of stamps we recycle we raise about £20.
