Now keep it safe: three things
  1. Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
  2. Save this receipt to your camera roll.

    Keep the receipt file too. The image is a handy copy; checking needs the file.

  3. Email it to yourself.Email it to myself

        How to keep notes that hold up

        Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.

        1. Write it down straight away, on paper or in the box on a step.
        2. Put the date, time and place at the top, and who you spoke to.
        3. Use their words where you can; separate what you saw from what you were told.
        4. Sign or initial a paper note, photograph it and add the photo.
        5. Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.

        Keep the application version you sent

        A school appeal file had a later application but lacked the one sent on time. The school kept treating the child as a late applicant. The ombudsman found faults and secured a fresh appeal, without saying the child must get a place.

        Missing application was one of several procedural faults; the outcome of a proper appeal remained uncertain.

        To reapply after a lost mailing, the rule listed a mailing receipt, a return receipt or agency receipt, or an online confirmation page; a notarized affidavit was added for 2009 onward.

        Proves / Doesn’t prove

        Proves

        A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.

        Doesn’t prove

        It does not prove you mailed anything, that the agency received it, who made it, or that it was on time; mailing and delivery are shown by the post office receipt and the agency's own rules.

        A timestamp does not prove mailing, receipt by an agency, timeliness or what physically went into an envelope.

        These are the bounds of a completed proof. The local tester does not establish any time. The chosen court, scheme or regulator decides what to accept.

        Questions, answered plainly.

        Your file stays on your device. During normal receipt creation, your device sends a randomized code made from its fingerprint, plus encrypted recovery data. It doesn't send the plain fingerprint or the random value that opens the code. Keep the original file and the complete receipt for checking. Privacy Policy.

        Does a copy of my application prove I mailed it?

        No. A copy preserves the document version you selected; a postal receipt records mailing. Together they do not establish what was physically inside the envelope.

        Is a time receipt proof of mailing?

        No. It shows these exact files existed by a date. Keep the post office receipt, and add a scan of it as the second file so the two are dated together.

        Did the postmark rules change?

        USPS added DMM 608.11 effective 24 December 2025. A machine postmark can show the first processing date rather than the drop-off date. Asking the counter for a manual postmark is the common workaround.

        Does the IRS accept a postmark as proof my document was filed on time?

        Under the statute, a postmark on or before the deadline counts as the delivery date for items mailed with prepaid postage and a correct address. Registered mail registration is prima facie evidence of delivery.
