From noon on 16 September, groep 7 and 8 children ring doorbells for Kinderpostzegels: 14 euro buys five cards and five stamps

Primary school children will ring your doorbell this week. The Kinderpostzegelactie is a fixed point in the Dutch September: pupils in groep 7 and groep 8 across the country go door to door from noon on Wednesday 16 September until Wednesday 23 September, selling stamps, cards and plasters for Stichting Kinderpostzegels. People meeting it for the first time tend to freeze in the doorway, unsure whether this is a sales call, whether money changes hands on the spot and whether saying no is rude. Three things settle it: the children take orders by QR code or paper form and do not handle cash, a set of cards and stamps costs 14 euro, and a polite nee, dank je is a normal answer, because this is a national fundraising week rather than doorstep selling.

• What makes it specific: this year's proceeds go to one named problem, children who are not safe at home, under the official line Veilig opgroeien. Dat moet gewoon. The 2026 stamps were hand-drawn by the Dutch design brand Blond Amsterdam, are self-adhesive for the first time and are cut in the shape of a house or part of one. (source 3)
• When and what it costs: from 12:00 on 16 September to 23 September, everywhere at once, with children staying in their own neighbourhood. One Kaarten en kinderpostzegels 2026 set is 14 euro and holds five Hallmark postcards plus a sheet of five self-adhesive children's stamps with stickers; children also carry stamps, plasters and a few items that change each year.

• Who it suits: parents with a child in groep 7 or groep 8, because the task comes home with them and a participating class receives a 150 euro Actieportemonnee to spend on a goal it chooses; and anyone who has just moved here and wants to see how the neighbourhood works, since this is the lowest-threshold Dutch conversation of the year.

• Check before you open the door: the children record an order rather than take payment, so do not press cash on them; the form needs your name, address and correct spelling because the goods arrive later; and the official page states neither a delivery date nor a way to opt out of the doorbell, so check the official page for both.

Do the sum yourself: a 14 euro set holds five cards and five stamps. For comparison, a PostNL stamp for a standard letter is still 1.40 euro after 12 July 2026, so five of them sit in the order of seven euro of postage, and the rest of the price covers the cards and the donation. The question is therefore not whether 14 euro is expensive but how many paper cards you will actually post this year: divide that number by five and you have the number of sets you will use, while anything above it is effectively a donation. If you only want to give money and have no use for cards, donate directly on the foundation's site; if you want to back the class standing at your door, one set does it. (source 4, source 1)

Hokimi field note: the doorbell rounds cluster between the end of the school day and dinner, and children from the same school usually come by two or three times during the week, so missing the first knock costs nothing. The line that matters is the address on the order form: it is written by you and delivered to you, and a misspelling means the cards never arrive.
