SIDN webpage for sale
This article explains how to list a .NL domain for sale using SIDN ForSale. ForSale works by publishing a special TXT record in DNS under _for-sale. SIDN (and other parties that support ForSale) can detect this and show that the domain is for sale, including a way for interested buyers to contact the selling party.
Important (Pilot → Production):
SIDN has moved ForSale from a pilot into production. If your domain currently uses the old TXT value that starts with idcode=, you must update it to the new production syntax.
Your unique code stays the same — only the TXT value format changes.
- 1) Add or update the TXT record in DNS
-
In your DNS management panel, create (or update) a TXT record at:
Host / Name:_for-sale
Type: TXT
Value:"v=FORSALE1;fcod=NLFS-<YOUR_UNIQUE_CODE>"
Example (do not copy the example code; use your own):
_for-sale.domain.nl TXT "v=FORSALE1;fcod=NLFS-<YOUR_UNIQUE_CODE>"
Old pilot format (for reference only):
If you previously used the pilot syntax, it likely looked like this:
_for-sale.domain.nl TXT "idcode=<YOUR_UNIQUE_CODE>"
Replace it with the new production value:
_for-sale.domain.nl TXT "v=FORSALE1;fcod=NLFS-<YOUR_UNIQUE_CODE>"
- 2) Verify the TXT record is visible using
- After saving your DNS changes, confirm the TXT record is publicly resolvable. Run the following command (replace the domain with your own):
dig
dig TXT _for-sale.gsm-easy.nl
Example output:
; <<>> DiG 9.10.6 <<>> TXT _for-sale.gsm-easy.nl ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 39126 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 1232 ;; QUESTION SECTION: ;_for-sale.gsm-easy.nl. IN TXT ;; ANSWER SECTION: _for-sale.gsm-easy.nl. 600 IN TXT "v=FORSALE1;fcod=NLFS-MDFlYjk2NmEtZTBhNC00ZmUzLTliOGUtNDYzOWU0MmE1N2E2" ;; Query time: 25 msec ;; SERVER: 192.168.1.1#53(192.168.1.1) ;; WHEN: Thu Feb 19 15:55:02 CET 2026 ;; MSG SIZE rcvd: 132
You should see an ANSWER SECTION containing: "v=FORSALE1;fcod=NLFS-..."
If you don’t see an answer:
• Double-check the host/name is exactly _for-sale in the DNS panel.
• Confirm you updated the correct DNS zone (the one used by the domain’s active nameservers).
• Wait for propagation (TTL/caching) and try again.
- 3) Open the ForSale page using our URL
-
The page where the domain is offered for sale can be accessed via:
https://mydomainprovider.com/for_sale_nl/<domain>
or:
https://mydomainprovider.com/for_sale_nl/?domain=<domain>
Example: https://mydomainprovider.com/for_sale_nl/?domain=gsm-easy.nl
If a captcha is shown, complete it and click Submit.

- 4) Confirm the selling provider details
-
After submitting, you will see the contact details of the selling provider. Interested buyers can use these details to reach out regarding the domain purchase.
Note: The contact details shown are based on the brand connected to the registrant.

- 5) Done
- You have now successfully listed your .NL domain for sale using the SIDN ForSale program.
