When you’re asked to send documents in an open envelope — especially when submitting paperwork to a public administration — it means the envelope should not be sealed when presented.

This is a common requirement for official document submissions through the post office or an administrative registry.

Why the Envelope Must Be Open

Verification

The clerk or postal employee needs to check the contents to confirm that the envelope only contains documents (not goods or other items).

Stamping Your Copy

They will stamp a copy of your documents as proof that your submission has been received (“received” or “filed” stamp).

Sealing After Review

After verification, the clerk will seal the envelope in your presence and send it officially to the corresponding authority.

Practical Steps

  • Prepare two copies of all your documents:
  • One for submission.
  • One for your records, to be stamped as proof of delivery.
  • Place everything in an envelope but do not seal it.
  • Go to the post office (or any official registry desk).
  • Tell them it’s for “administrative submission” or “official registry by post.”
  • They’ll open or check the envelope, stamp your copy, and then seal it.
  • Keep your stamped copy as legal proof that you submitted your paperwork.

Example

You’re sending signed forms to a government office or university.

They request the documents “in an open envelope.”

→ Bring the envelope open.

→ The clerk checks and stamps your copy.

→ They close it and send it officially.
