Where to send your Poseidon cancellation letter

Read the addresses on this page next to the full guide to cancelling Poseidon.

The addresses we hold

The address a cancellation letter to Poseidon needs, and every other address we hold, starting in Göteborg: copy the lines exactly and the envelope sorts itself.

Where the letter goesMailing address

PoseidonÖstra Hamngatan 16411 09 GöteborgSweden

The Sweden address on file for Poseidon. Postal code 411 09.

How to address the envelope

  1. Use the address letter for letter

    One address block, copied whole: Östra Hamngatan 16, 411 09 Göteborg, Sweden. If any line differs from the card above, start the envelope again.

  2. Put your own address on it

    Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.

  3. Certified mail, not a courier

    Take the letter to a post office counter and ask for certified mail: you get a postmarked receipt and a delivery record. Keep the tracking number and check it until it shows delivered.

  4. File the receipt with your copy

    Your copy of the letter, the mailing receipt and the tracking record belong together in one file.

The cancellation letter

A plain, dated letter to Poseidon asking for the cancellation, the end of every charge and written confirmation. Have the name and email on the account and, if you have one, an account or customer number to hand; our letter template fills the same shape in on screen.
