Where to send your GPTZero cancellation letter

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

The addresses we hold

Every address our database holds for GPTZero, with the New York one a cancellation letter goes to first and the envelope wording that matches it.

Where the letter goesMailing address

GPTZero33 Irving PlNew York, NY 10003

GPTZero takes its post at this New York address (ZIP 10003).

Second address on file

GPTZeroIrving Place 33New York 10003

The database lists this as a second address for GPTZero. Use the primary address above unless your agreement names this one.

How to address the envelope

  1. Copy it exactly onto the envelope

    The front of the envelope carries 33 Irving Pl, New York, NY 10003 and nothing else in the address block. Check the 10003 digit by digit before it goes in the post.

  2. Add the return address

    Your name and postal address go top-left on the front (or the back flap). If the letter cannot be delivered it comes back to you, which is itself evidence of the attempt.

  3. Send it by certified mail

    At the counter, certified mail costs a fee on top of the postage and comes with a mailing receipt and a delivery record. The tracking number on the green label is what you follow.

  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 letter to send

The request itself is short: GPTZero is asked to end the account, stop the charges and confirm in writing, with the account email, the plan or product name and the invoice or order number from your latest receipt where the brackets are.
